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

Pediatric Ct Scan is a quick and painless examination that uses x-ray equipment to create detailed images of the child’s internal organs, bones, soft tissues and blood vessels. Pediatric Ct Scan examinations are used to help diagnose abdominal pain and evaluate trauma injuries. This type of research is quantitave research using analytical observational methods, this research has been done on 25 April- 16 June 2022 with 10 patient’s famillies as research sample. Measurement of the radiation dose of the tyroid organ of the patien.s famillis using a DMC 300 pendose measuring instrument by means of a tool tied to the left side of the patient’s famillies neck (the part that is not covered by the apron). The results of the study of the radiation dose of the tyroid organs of the patient’s family produced avarage for a scanogram of 0,001 mSb, for scanning results an average of 0,0187 mSv was obtained, the average value of the quivalent dose was 0,0187 mSv and the average value of the effective dose was 0,0000748 mSv. The average obtained is still categorized as safe for the general public when compared to PERKA BAPETEN no.8 of 2011.

Abstract

Diagnosis of orbital is recommended for orbital MRI examinations, on of the pathology is retinoblastoma. orbital organs contain a lot of soft tissues so the orbital MRI is one of the right choices because it can appear anatomically and pathologically in a cross-sectional orbital, in two dimensions and three dimensions. Examination protocols on orbital MRI in retinoblastoma cases have several sequences in pre- and post-contrast agent. The purposes of this research were to determine the orbits MRI procedure in the retinoblastoma case. The Method of this research is a descriptive of qualitative with case study method. The data were collected in unit of radiology DR. Saiful Anwar Malang by using observation method, documentation, and interview of radiolog and radiographers. Data analyzed by using presented and data reduction to get the conclusion and suggestion. The results are an orbital MRI examination is concerned with MRI safety with patient screening and informed consent. The protocol for pre-contrast agent orbital MRI was T1 3D TSE axial, T2 TSE axial, DWI axial, T2 TSE fat saturated axial, and T2 DRIVE axial. On post-contrast agent using sagittal T1 FFE sequences, T1 3D TSE axial. The use of slice thickness is 3mm and 1mm in 3D image, 2D T2 DRIVE and 2D T1 FFE post contrast. gadolinium contrast agent as much as 5 mmol/10ml injection intravenously. The selection of sequences in the protocol of orbital MRI can produce detailed orbital anatomy images and provide sufficient clinical information to diagnose retinoblastoma.

Abstract

Low Back Pain (LBP) is a pain condition that attacks the lower part of the spine, caused by injury to muscles or ligaments, common causes include lifting the wrong weight, poor posture, not exercising regularly and so on. One of the radiological examinations to establish the diagnosis of LBP is a radiographic examination of the lumbar spine. In the examination procedure, the radiological examination of the lumbar spine, the patient's position during the examination was arranged to sleep supine on the examination table, while at RSI Purwokerto the examination of the lumbar vertebrae with the case of LBP the patient position setting was arranged to stand in front of the bucky stand. The research used in the preparation of this scientific article is qualitative research with approach case study, the method of data collection is carried out by direct observation of the technique of radiographic examination of the lumbar spine with LBP cases at the Radiology Installation of Islamic Hospital Purwokerto and data collection methods by taking data from documents, including radiographs, medical records and radiographic readings. On radiographic examination of the lumbar spine with LBP cases with the patient standing, the results were: low back pain with normal lumbar curvature and no disc narrowing. Conclusions that can be drawn from the technique of examining the lumbar vertebrae at the Radiology Installation of the Islamic Hospital of Purwokerto were carried out with the AP and Lateral erect projections. the use of this projection can be more informative and can clarify the intervertebral space or narrowed intervertebral disc.
