Background: Stroke is a diseas that has a high mortality rate as the third most common disease that causes death in the world. To diagnose the location and type stroke, a neuro imaging examination is need, which is by examining the CT Scan of the head. The purpose of this study was to determine differences in diagnostic information on CT scan of the head in cases of ischemic stroke with a choice combination of 3 mm slice thickness with 1.5 mm interval reconstruction and 2 mm slice thickness with 1 mm interval reconstruction, and to find out which combination is the most optimal in producing diagnostic information in cases of ischemic stroke. Methods: This type of research is quantitative research with experimental approach. The study was conducted at Telogorejo Hospital Semarang. The sampel in this study were 10 patients with expertise results of ischemic stroke. The resultan data was 10 head scan radiographs with ischemic stroke and each radiograph is reformatted with combination of 3 mm slice thickness with 1.5 interval reconstruction and 2 mm slice thickness with 1 mm interval reconstruction. Assesment of diagnostic information data was done by 3 respondents. before data analysis, first kappa test was done to three respondents and then tested wilcoxon. Result :The result of this research is the difference of diagnostic information between combination of 3 mm slice thickness with 1.5 mm interval reconstruction and 2 mm slice thickness with 1 mm interval reconstruction. A combination of 2 mm slice thickness with 1 mm interval reconstruction with mean rank 21.00 is the most optimal combination for head scan with ischemic stroke cases

Background: Cardiac angiography CT examination is a non-invasive measure to evaluate coronary blood vessels. Multislice CT with a high level of sensitivity and specificity is required to be able to reconstruct data from a constantly moving heart, resulting in diagnostic and informative image quality. Heart movement or heart rate plays a role in the occurrence of motion artifacts so that a stable heart rate is required at the time of data acquisition. The purpose of this paper is to see the role of the heart rate in cardiac CT Angiography examination and to determine the value of the heart rate to obtain the best image quality. Methods: The research method uses a literature study approach by describing the article. Article searches use Science Direct, Radiopedia, American Journal Radiography, and Google Search to find articles that match inclusion and exclusion criteria so that 4 articles are obtained and then they are reviewed. Results:: The study results show that the heart rate plays a very important role in producing image quality from CT examination. Cardiac angiography, a stable heart rate will minimize the occurrence of artifacts, which is one of the points in the image quality parameter. A stable heart rate to get the best image quality is at â‰¤60 BPM when data acquisition with low heart rate variability Conclusion: .Nilai heart rate untuk mendapatkan kualitas citra yang informatif dan diagnostik pada nilai heart rate 60 bpm, sehingga kualitas citra akan baik.

Background: Ischemic stroke is a critical condition detectable through head CT scans, where windowing techniques significantly enhance brain tissue visualization. At Bethesda Hospital Yogyakarta, differing windowing protocols are used in the Emergency and Main Radiology Departments, yet no standardized stroke-specific window has been established. This study aims to identify the differences in anatomical information in head CT scans with various windowing settings and to determine the most optimal windowing protocol.Methods: This research is a quantitative-experimental study conducted at Bethesda Hospital Yogyakarta involving 10 patients with ischemic stroke, using variations of windowing settings: WW 120 HU WL 60 HU, WW 100 HU WL 35 HU, and WW 40 HU WL 40 HU. The image results were evaluated by two respondents based on the anatomical information of brain parenchyma, insular cortex, internal capsule, left and right cerebral hemispheres, and brain sulci. The data analysis was performed using the Friedman statistical test.Results: The results of the study showed that the WW 100 HU WL 35 HU setting provided the most informative anatomical visualization across all evaluated brain structures. In contrast, WW 120 HU WL 60 HU was the least informative for the brain parenchyma and insular cortex, while WW 40 HU WL 40 HU offered moderate clarity for most structures but was suboptimal for the brain parenchyma. These differences were confirmed by the Friedman test, with a p-value 0.05.Conclusions: There were differences in anatomical information across the various windowing settings in head CT scan examinations for ischemic stroke cases. In addition, the highest overall and individual anatomical mean rank was found in the WW 100 HU WL 35 HU windowing setting, with a value of 2.95.

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.

Background: Pulse gradient echo sequences use varying RF excitation pulses and with NMV flips through various angles (not just 90Â°). 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.
