Abstract

Background: Increasing the exposure factor is often carried out by radiographers to reduce noise and maintain image quality in computer radiography (CR). Therefore, there is a need for awareness and understanding of the exposure index (EI) to implement optimization procedures in radiographic examinations. Methods: The research method is descriptive and analytical by providing questionnaires to radiographers in PA chest radiographic examinations. This research was carried out at hospitals A, B, and C in the Jakarta-Bogor area with the research carried out between August – October 2023. Statistical analysis used SPSS 27 with data coding previously. After that, the data is processed with descriptive statistics to determine the frequency, distribution, percentage, average, and standard deviation. Then, the test chi-square to determine the relationship between gender, age, education, and work experience in understanding CR optimization procedures. Next, to find out the relationship between age and weight and EI, a test was carried out by Pearson test to determine the level of relationship between the two variablesResults: was found that the level of awareness and understanding of radiographers regarding optimization procedures using EI is still low. Test results chi-square age-understanding 0.309, gender-understanding 0.772, education-understanding 0.036, experience-understanding 0.201. next are the test results Pearson for Hospital-A: age-EI 0.09, weight-EI -0.49, Hospital-B: age-EI -0.21, weight-EI 0.06, Hospital-C: age-EI -0.37, weight-EI 0.56. Conclusions:  implementing EI in the optimization procedure, it needs to be confirmed by measuring the patient's radiation dose so that there are no errors in implementing the optimization.

Abstract

Background: Pulse gradient echo sequences use varying RF excitation pulses and with NMV flips through various angles (not just 90°). Gradient echo has a sensitive susceptibility effect in detecting the presence of blood products (hemorrhage) and calcifications in brain tumors. The SWI and T2 FLASH 2D sequences are part of the pulse sequence gradient echo, where the SWI sequence is a 3D velocity compensated gradient echo and the T2 FLASH 2D sequence is a 2D multi-slice gradient echo. This study aims to determine the differences in axial image diagnostic information and determine the most optimal axial image diagnostic information in MRI brain examinations between SWI and T2 FLASH 2D sequences in brain tumor cases.Methods: This type of research is quantitative with an experimental approach. Data was taken in March 2024 at the Radiology Installation of RSUP Dr. Sardjito Yogyakarta. The sample in this study was 10 patients with brain tumor cases. An assessment was carried out by 2 respondents to assess the criteria for brain tumors. The assessment data from respondents was tested using the Cohen's kappa test to assess reliability between respondents and the Wilcoxon test to determine the level of difference in axial image diagnostic information, then the mean rank was used to determine sequences with better diagnostic image information.Results: The results of the study show that there is a difference in the diagnostic information of axial images on MRI brain examination between SWI and T2 FLASH 2D sequences in tumor cases with a p-value of 0.014. The significant difference is due to the susceptibility effect in both sequences. Based on the Wilcoxon test, the SWI sequence is the most optimal sequence in displaying diagnostic information with a mean rank value of 4.Conclusions: There is a difference of axial image diagnostic information between SWI and T2 FLASH 2D sequence in Brain MRI with brain tumors cases, and SWI sequence produces the most optimal axial image diagnostic information in MRI brain with brain tumor cases.

Abstract

Background: The bisecting angle technique of periapical radiography is more often used in dental practice because the technique is practically adjustable and the patient's ability to adapt is better. Radiograph results are influenced by operator and patient factors, so management that is not optimal can cause a decrease in the quality of the radiograph, which affects interpretation, diagnosis, and treatment planning. The study aimed to determine the quality and frequency of errors in periapical radiographs using the bisecting technique due to errors in X-ray angulation and film placement at the Soelastri Dental and Oral Hospital (RSGM), University of Muhammadiyah Surakarta (UMS).Methods: The type of research is descriptive observational quantitative research with a retrospective approach. A total of 300 bisecting technique periapical radiographs from patients at RSGM Soelastri UMS in January–December 2021 who met the inclusion and exclusion criteria were taken in random stratification and evaluated. Radiographs are compared to ideal quality and given a National Radiological Protection Board (NRPB) rating, as well as looking at the frequency of errors that occur.Results: The rating most often obtained on periapical radiographs using the bisecting technique in the study was 2 for 181 radiographs (60.33%). The frequency of X-ray angulation errors was 62.94%, while the frequency of film placement errors was 37.06%. The highest error in X-ray angulation was cone cutting at 49.13%, while the error in film placement was in the form of apical cuts at 25.65%.Conclusions: The quality of periapical radiographs using the bisecting technique at the Radiology Installation at RSGM Soelastri UMS in the period January to December 2021 generally has a rating of 2 (diagnostically acceptable) according to the NRPB, and errors are still found in the angulation of the X-ray tube and film placement.

Abstract

Background: Abdominal radiography examination is one of the examinations that is routinely carried out on the abdominal area to diagnose abnormalities in the abdominal area using radiation. In the stomach area there are gonads which are organs that are sensitive to radiation. The X-rays that come out of the X-ray tube are polyenergy, that is, they are composed of low energy x-ray, medium energy x-ray and high energy x-rays. Low energy x-rays have no benefit on the radiographic image information produced, but only increase the radiation dose on the skin surface. The additional x-ray filter is able to prevent low-energy x-rays from hitting the patient. The aim of this study is to determine the difference in the dose of radiation during the abdominal examination between the use of an additional filter and the use of an additional filter without an additional filter.Methods: The research was carried out at the Radiology Unit of the Prof. Dr. Margono Soekarjo Regional Hospital, Purwokerto and the Purwokerto Radiology Study Laboratory, Poltekkes Semarang with a sample of 50 samples with variations in the use of filters including 0 mm, 1 mm Al + 0.1 mm Cu, and 1 mm Al + 0.2 mm Cu and 2 mm Al. The data measured is the radiation dose On the surface of the Gonad organ's skin.Results: The results of measuring the average dose to the skin surface of the gonad organ are 180.26 mSv on a 0 mm Al filter, 83.32 mSv on a 1 mm Al + 0.1 mm Cu filter, 58.32 mSv on a 1 mm Al + 0 filter, 2 mm Cu and 119.49 mSv on a 2 mm Al filter. The greatest reduction in radiation dose occurred when using an additional filter of 1 mm Al + 0.2 mm Cu, amounting to 68% of that without using an additional filter. The decrease in the use of other filters was 54% when using an additional filter of 1 mm Al + 0.1 mm Cu and 34% when using an additional filter of 2 mm Al. The statistical tests showed there was a difference in the radiation dose during abdominal examination between using an additional filter and without using an additional radiation filter with a significance value of 0.000 (p-value 0.05).Conclusions: There is a difference in radiation dose during abdominal examination between using an additional filter and without using an additional filter with a significance value of 0.000 (p-value 0.05).

Abstract

Background: CT scans have a much greater dose than conventional radiographic examinations. The thyroid organ is an organ that is sensitive to radiation which is located near the head, precisely in the inferior part of the head so that when a CT scan of the head is carried out, the thyroid organ will be exposed to radiation. The aim of this study was to determine the difference in thyroid skin dose entry value between using a thyroid shield and without a thyroid shield on a head CT scan.Methods: This study is a type of quantitative research with a pre-experimental design. The object of research is Entrance Skin Dose (ESE) of ThyroidOrgan on non-contrast head CT Scan examination. The research location is at the Radiology Department at the Regional General Hospital Prof. Dr. Margono Soekarjo Purwokerto. Sample data number is 50 people (25 samples of non-contrast head CT scans without thyroid shield, and 25 samples of non-contrast head CT scans with thyroid shield. Data was obtained by measuring the radiation dose using a dosimeter placed over the thyroid area during a non-contrast CT scan between using a thyroid shield and without using a thyroid shield. Data analysis was performed using statistical tests Results: The results of measuring the radiation dose to the samples showed that the average radiation dose to the skin surface of the thyroid organ on a non-contrast CT scan without using a thoracic shield was 884.96 µSv and using a thyroid shield was 428.64 µSv. This shows that the average radiation dose from the skin surface of the thyroid organ decreased by 456.32 µSv (51.56%).Conclusions: There is a significant difference in the amount of radiation dose to the surface of the skin of the thyroid organ in non-contrast head CT scans between using a thyroid shield and without using a shield with a dose reduction of 51.6% of the radiation dose without using a thyroid shield.

Abstract

Background: The use of PD TSE fat saturation (FS) sequences in coronal section of the MRI knee joint routine examination revealed artifacts caused by popliteal artery pulses. Meanwhile, there is T2 FS sequence with the BLADE technique that can reduce motion artifacts, but isn't used in the knee joint routine MRI examinations. BLADE is a technique of filling radial k-space around the center of k-space, thereby reducing motion artifacts and improving image quality. The aim of this study is to determine the differences in anatomical information, artifacts, and sequences that optimally reveal the anatomical information of knee joint between the PD TSE FS and T2 FS BLADE coronal section.Methods: This study used a quantitative research methods with an experimental approach. The sample of this study are 10 healthy volunteers and 2 radiologists as respondents. Each volunteer undergo an MRI knee joint examination with the PD TSE FS and T2 FS BLADE coronal section. The results of the two sequence images were assessed by the two respondents to obtain data for assessing anatomical information on the ACL, PCL, collateral ligament, articular cartilage, meniscus, subchondral bone, and artifact information. Data that has been obtained is processed using the Wilcoxon test.Results: The results shows that there are differences in the anatomical information of ACL, PCL, articular cartilage, and meniscus between the PD TSE FS and T2 FS BLADE coronal section. Meanwhile, there is no difference in the anatomy of the collateral ligament and subchondral bone. There is also a difference in artifact information between the two sequences.Conclusions: The T2 FS BLADE sequence is more optimal than the PD TSE FS sequence in displaying anatomic information and is also more optimal in suppressing ghosting artifacts from the popliteal artery pulse.

Abstract

Background: Kidney stones are a clinical condition with the presence of stones along the urinary tract of varying sizes. The aim of this research is the need for a system to automatically detect kidney stones so that it can help radiologists in diagnosing kidney stones accurately, effectively and efficiently, and patients can immediately undergo further action to cure kidney stones.Methods: The difference in research carried out by researchers is the use of artificial intelligence which uses deep learning with a convolutional neural network (CNN) algorithm. This research uses images obtained from CT scan results from public data (Kaggle) and primary hospital data. The number of images used in the Augmentation training data was 2338 normal images and 2390 kidney stone images. The augmentation testing data used 540 normal images and 446 kidney stone images. The research also involved experts, namely radiology specialists, in determining images with abnormal and normal stone tones.Results: research obtained from CT Scan images of kidney stones with augmentation and original using public data/Kaggle images, obtained using augmentation obtained a high accuracy value of 99.69%. Meanwhile, in testing data using primary/hospital data images, augmented data obtained accuracy values that were still low at 45.43% and 45.23%, respectively.Conclusions: The use of deep learning with the CNN model in training data augmentation obtained high accuracy values, however in testing data using hospital CT scan images the accuracy value was still low, but it was able to recognize images of kidney stones, so it could help in automatically diagnosing kidney stones. For future work could involve refining the model to handle variations in hospital data or exploring additional features to improve generalizability.

Abstract

Background: CT Coronary Angiography (CTCA) is a non-invasive imaging modality with a high spatial and temporal resolution to diagnose coronary vascular disease. FBP (Filtered Back Projection) has limitations in improving the image quality, so iterative reconstruction is used on CTCA. Adaptive Iterative Dose Reduction (AIDR 3D) is one of the iterative reconstructions developed by Toshiba, which has three levels of strength: mild, standard, and strong. The study aimed to explain the application of AIDR 3D in improving image quality on coronary CT angiography examination. Methods: This research is descriptive with a literature study approach, using articles from NCBI, Science Direct, and Google Scholar. The keywords used are CT Coronary Angiography, AIDR 3D, and Image Quality. The articles obtained are reduced based on inclusion and exclusion criteria so that seven relevant articles are conducted for extraction.Results: The results showed that AIDR 3D could improve the quality of CTCA images with the most significant percentage in AIDR 3D strong by reducing noise 18-46.1% and increasing SNR 21-84.7% and CNR 21-82.2%.Conclusions: The application of AIDR 3D strong in obese patients with CTCA is good to use with standard kVp and 250-450 mA without increasing mA so that it does not increase the dose. AIDR 3D strong can also be used in patients with normal body mass with tube current adjusted according to the patient's body mass if there is no indication on the right coronary artery. AIDR 3D standard can be used in overweight patients and normal body mass.

Abstract

Background: Technically, by applying MR Spectroscopy it possibly makes that signal from several numbers of different chemical compounds can be obtained, separated, and quantified in simultaneous way. In relation to which, the quantification of brain metabolites in 1H MRS depends on the separation of spectroscopy signal of each metabolites. In this matter, spectrum results will be influenced by the size of volume of interest. In this matter, volume of interest (VOI) is a specific area in the tissue, whereby the metabolites of which, are analyzed. This research aims to analyze the comparison of the results of brain MRS spectrum with the different variation of Volume of Interest (VOI) measurements in MRI Phillips 3T.Methods: Design of this research applies quantitative method with experimental approach by using Philips Ingenia 3 Tesla MRI machine undertaken at radiology installation of Regional General Hospital Ciawi toward 11 brain MRI patients undergoing Magnetic Resonance Spectroscopy with the different variation size of Volume of Interest (VOI) namely 1.0 × 1.0 ×1.0 cm, 1.5 × 3.0 ×1.5 cm, and 2.0 × 2.0 × 2.0 cm.Results: This research suggests that there is a different height of NAA, Choline, Creatine, and Glx metabolites whereas for Myo-inositol, Lipids and Lactate metabolites there is not any significant difference. Meanwhile for Full Width Half Maximum, there is a significant difference with different variation of volume of interest (VOI).Conclusions: There is a significant difference in the height of metabolites NAA, Choline, Creatine, Glx (p value 0,05), whereas for metabolites of Myo-Inositol, lipids, and Lactate (p value 0,05) there were no significant differences at different variations of Volume of Interest (VOI). There is a significant difference with a p value of 0.000 0.05 in the Full Width Half Maximum (FWHM) value with different Volume of Interest (VOI) variations where the highest average Full Width Half Maximum (FWHM) value is VOI C (2.0 × 2.0 × 2, 0 cm) with an average of 21.476 followed by VOI B (1.5 × 3.0 × 1.5 cm) of 20.603 and the lowest average FWHM value is VOI A (1.0 × 1.0 × 1.0 cm) of 15.985 which means that the larger the size of the Volume of Interest (VOI), the higher the Full Width Half Maximum (FWHM) value will be. The size of the Volume of Interest (VOI) for the hippocampus area must be adjusted to the size of the patient's hippocampus because a size that is too large will cause unwanted areas to enter the Volume of Interest (VOI) and affect the spectrum results.
