Abstract

The Filtered Back Projection (FBP) algorithm has been the standard algorithm for image reconstruction in computed tomography (CT) for many years, but it creates possible streak artifacts and a notable increase in image noise when radiation dose is reduced exceedingly. With technological advancement and increased computational capacities in workstations,Adaptive Statistical iterative reconstruction (ASIR) algorithms have reemerged as a potential alternative. The purpose of this review is to establish if there is a general consensus that ASIR algorithms faithfully reduce radiation dose and improve image quality in CT in comparison with the FBP algorithm. A systematic review of the literature from 2011 to 2022 was conducted using Elsevier, Google Scholar, Pubmed, AJR, dan Science Direct, Physica Medica and the Korean Journal of Radiology. A total of 11 articles were categorized as either synopsis articles or performance evaluation clinical studies. The results show that the use of IR algorithms reduces objective image noise, and at least preserves spatial resolution and low contrast detectability, even when dose is reduced. In conclusion, there is a general that ASIR algorithms can faithfully reduce radiation dose but must notice about ASIR level to improve image quality in CT in comparison with the FBP algorithm.

Abstract

Background: The hospital has standardized the selection of sequences used for MRA examination. In the Radiology Installation of Arifin Achmad Hospital, Riau Province, only one time of flight sequence was used from two non-contrast MRA sequences, namely time of flight and phase contrast. In this regard, there are two sequences of non-contrast MRA examination that need to be used in order to identify and produce a good image of the renal vessels. Methods: This study is a quantitative study with an experimental approach that aims to determine differences in information on anatomical MRA Renal images using 2 non-contrast MRA methods, namely time of flight and phase contrast. This study applies the Lemeshaw formula with a 95% confidence level, using 10 Renal MRA patients and 3 radiology specialists as respondents for image assessment. Results: The results showed that there was no difference between tof and pc sequences in the anatomy of the renal arteries and segmental arteries. However, there were significant differences shown in the anatomical assessments performed (interlobar arteries, arcate arteries, and interlobular arteries). Almost all indicators show a p-value of <0.050, with the 3d time of flight sequence showing superiority in all aspects assessed compared to the 3d phase contrast sequence. Conclusion: There is a difference in anatomical image information on the Renal MRA using 3d time of flight sequences and 3d phase contrast. In the 3d time of flight sequence, it is able to produce arterial images well but lacks in displaying venous images. On the other hand, the 3d time of flight sequence is good at showing veins and lacking in arterial imaging. Keywords: mra renal; time of flight; phase contrast

Abstract

The principle of using contrast media is to influence the magnetic field and relaxation times of T1 and T2. Contrast media in MRCP consists of positive and negative contrast media. Gadolinium is a positive contrast medium with intravenous injection, while the negative contrast medium used must contain manganese (Mn) or iron (Fe) (Westbrook et al, 2016). Research conducted by Suhardi et al (2013) states that the use of positive contrast media is increasingly rarely used due to the high price and difficult to obtain, it also has side effects on patients, such as weakness, nausea and vomiting. According to Fatimah et al (2018), natural ingredients with relatively high manganese (Mn) content that can be used as negative oral contrast media, one of which is the manganese content in packaged oolong tea, which is 0.9 mg. At the Radiology Installation of Prof. RSUP. DR. R. D. Kandou Manado by using boxed tea as a substitute for positive contrast media which is expensive and has side effects on patients.This type of research is a qualitative research with interview, observation and experiment methods. This study used the original box tea and blackcurrant box tea as negative oral contrast media to 3 volunteers. The examination was carried out twice for each volunteer, using the original box tea in the first week and blackcurrant box tea in the second week. The results of the images obtained will be asked for opinions through interviews with respondents, namely 1 radiology doctor and 2 radiographers. Data is processed using a coding system. MRCP examination procedure at Prof. RSUP. DR. R. D Kandou Manado includes patient preparation with the patient fasting 6 hours before the examination with the aim of avoiding fluid in the duodenum which can interfere with the biliary tract and bile duct into the duodenum. Instructions for drinking boxed tea contrast media were carried out 10-15 minutes before the examination, followed by preparation of equipment, patient position, protocol and examination technique. The resulting image does not provide a difference between the use of the original box tea and blackcurrant box tea on the anatomical image information on MRCP. The advantages of using negative oral contrast media, Teh Kotak, is able to help reduce signals from CBD and Vater's ampulla, as well as being able to display MRCP images that are better than using other negative contrast media. Patients with diabetes are not recommended to use this contrast medium.

Abstract

Background: Shoulder Joint MRI examination is one of the musculoskeletal examinations that is often carried out in the MRI modality because the Shoulder joint is one of the most active joints. In order to be able to visualize a good image, the right coil is needed, in the shoulder joint MRI examination it is recommended to use a shoulder array coil or shoulder coil. This examination can also use a flex coil in an MRI shoulder joint examination at the hospital if the congenital shoulder coil is damaged. The shoulder coil has better image quality because of its shape that surrounds the entire object you want to examine. Methods: This study used a quantitative approach with a quasi-experimental approach, namely conducting experiments on the observed objects, to find answers to the problems raised by conducting an MRI Shoulder Joint examination using two different types of coils, namely Shoulder coil and flex coil in 10 samples. The data is then processed using SPSS. Results and Conclusions: Based on the results of statistical test calculations for the SNR value of the anatomy of the shoulder joint, there is a significant difference in image quality, namely the SNR of the anatomy of the shoulder joint using shoulder coil and flex coil which has an overall p value/sig of 0.038 so that Ho is rejected and Ha is accepted. The average SNR for shoulder coil was 312.41 and flex coil was 246.30, so the difference in the SNR value for MRI shoulder joint using shoulder coil compared to flex coil was 66.11. With these results, the more optimal MRI Shoulder joint examination uses the Shoulder coil. Keywords: Shoulder Coil, Flex Coil, Signal to Noise Ratio (SNR)

Abstract

One of the efforts to optimize radiation protection and safety in the implementation of diagnostic and interventional radiology procedures for patients is to apply the Diagnostic Reference Level (DRL) according to the type and object of examination carried out. The level of diagnostic guidance for medical exposure or DRL is highly recommended to be used as a guide for medical practitioners in optimizing protection in each type of diagnostic and interventional radiology examination and is used to prevent unnecessary radiation exposure in patients. Each Radiology Installation needs to conduct a routine evaluation of the dose value received by the patient and compare it with the latest Indonesian Diagnostic Reference Levels (IDRL) so that its implementation becomes effective. This study aims to evaluate the value of CTDI and DLP in the Adult Abdomen CT-Scan Examination at the NTB Provincial Hospital. This study uses descriptive quantitative research with a survey approach that aims to evaluate the value of CTDI and DLP in the Adult Abdomen CT-Scan examination at the NTB Provincial Hospital. This study was conducted by collecting data sourced from the Abdominal CT-Scan Examination. The facilities DRL value is calculated by using the quartile formula 3 (75 percentile) in Microsoft excel automatically, then compared with the latest IDRL value. The calculation of the quartile value of 3 (75 percentile) from CTDI and DLP received by patients at the adult Abdominal CT-Scan Examination at the NTB Provincial Hospital, obtained as many as 60 samples. Drl or quartile 3 (75 percentile) values obtained for CT-Scan Abdomen Contrast were 16.60mGy for CTDIvol and 1344.57mGy*cm for DLP. As for the Non-Contrast Abdominal CT-Scan of 15.15mGy for CTDIvol and 797.97mGy.cm for DLP. The value of 75 percentile of CTDI and DLP received by patients on the adult Abdominal CT-Scan Examination while at the Provincial Hospital is in accordance with the recommendations of BAPETEN / IDRL 2021.
