Abstract

Background : MRCP is a biliary tract and pancreatic duct imaging technique, one technique that uses a breath hold. The technique speeds up acquisition time by using the Parallel Imaging ARC method so that it reduces the encoding phase on K-Space to reduce breath hold. Therefore it can increase image sharpness and reduce blurring image. The purpose of this study was to determine the differences in anatomical image information between using ARC and without using ARC on MRCP examination of coronal T2 FRFSE sequence pieces and to find better anatomical image information between using ARC and without using ARC on MRCP examination of FRFSE T2 sequences.Method : The type of research conducted by the author is quantitative research with an experimental approach. This research was carried out with 1.5 T MRI at Santo Borromeus Hospital, Bandung. Data in the form of 16 MRCP anatomical images of coronal chunks of T2 FRFSE sequences from 8 patients using ARC and without using ARC. Scores on the image are carried out in the gallbladder, cystic duct, common hepatic duct, intra-hepatic duct, common bile duct and pancreatic duct using questionnaires to 3 radiology specialists (respondents). The results of the respondents were analyzed using Wilcoxon statistical test to find out the differences in MRCP anatomical information on FR2E T2 sequences between using ARC and without using ARC and to find better anatomical image information from the two sequences seen from the mean rank value.Result : The results showed that there were significant differences in MRCP anatomical image information of coronal T2 FRFSE sequences between the use of ARC and without using ARC with a significance value of 0.05. Based on mean rank results, MRCP information on T2 FRFSE sequence coronal pieces using ARC has a mean rank value of 4.50 while MRCP T2 FRFSE coronal sequence sequences using without ARC have a mean rank value of 0.00, meaning FRFSE T2 sequences using ARC have better image information than FRFSE T2 without using ARC.Conclusion : Suggestion, the parallel imaging technique of the ARC method was applied on the MRCP examination of T2 FRFSE sequences and the data from this study could be used as baseline data to add ARC as the operational standard of the MRCP examination procedure.

Abstract

Background : There are three ways to protect yourself from the danger of radiation, namely by regulating the length of irradiation (the effect of time), the use of anti-radiation material (shielding), and adjusting the distance from the radiation source (distance). In order to be safe in carrying out x-ray irradiation, patients and operators must take three steps so that radiation hazards can be minimized (Nunung, 2004). One way to check the danger of external radiation is to use a radiation barrier. This method is generally preferred, because it creates safe working conditions. Besides that the time and distance factors can be monitored continuously at the time of work, so that radiation workers can be guaranteed safety.Methods: This research is quantitative research with an experimental approach. The method of data collection in this study is observation, direct experiments and documentation. The types of sand to be used in this study are south beach sand, opaque sand, progo sand, white mountain sand and volcanic sand.Result :  Concrete using sand material from South Beach has the lowest HVL value of 0.8644cm. Conclusion :The HVL value possessed by concrete with South Beach sand material is most effective in resisting x-ray radiation.

Abstract

Backgroud: Previous researches show that the use of out of plane shielding can reduce the radiation dose received by radiosensitive organs around the scan area on CT scan. There is a special shielding designed for CT scans, but currently the type of shielding available in almost all radiology installations is the lead apron. This study aims to determine the dose received by the breast area on CT abdominal scan without shielding and its reduction by giving lead apron shielding on 1800 and 3600.Methods:This is quantitative research with a pre-experimental design. Abdominal CT scan was performed on a whole body CT phantom whose characteristics are close to human body tissue. The radiation dose received by the breast area was measured by Termoluminisence-dosemeter (TLD). TLD’s were placedon the same points. Scanning was performed using Siemens Somaris/5 Syngo, repeated in three conditions: without shielding, lead apron shielded (equivalent to 5 mm Pb) by 1800 and 3600. The rouitne protocol was used (120 kv and 200 mA) Data was analyzed by Paired t-test to determine the difference in radiation dose received and descriptive analysis for know the level of reduction.Results:The radiation dose received by the breast area without shielding, with shielding 1800, and with shielding 3600 were respectively 0.653 mSv, 0.367 mSv, and 0.242 mSv. There were significant differences in the dose received by the breast area (p value 0.05) by using shielding. Compared to unshieldied condition, there was a decrease of 43.95% when shielded 1800, and a decrease of 62.94% when shielded 1800.Conclusion:Lead apron is effective for reducing radiation dose on breast in abdominal CT. 3600 shielding provides higher reduction than 3600 shielding, so it can be considered to be applied in clinical procedure.
