Background: Have been done research on inspection procedures examination in the case of abdominal CT Scan cholecystitis at Radiology installationProf. Dr. Margono Soekarjo Purwokerto Hospital. This study aims to determine the inspection procedure examination in the case of abdominal CT Scan cholecystitis not using the biphase technique diagnosis and to find out information on examination in the case of abdominal CT Scan cholecystitis with monophase technique at Radiology installationProf. Dr. Margono Soekarjo Purwokerto Hospital.Methods:This type of research is aqualitaive research case study approach. The data collection methods with unstructured observation , depth interview with 3  radiographers, 1 radiologist, a sending doctor and a patient, and the documentation of the results of reading radiographs and photographs. The data obtained  then reduced, classified, dried and then interpreted in the form   then  concluded kuotasi and suggestions.Results: The result showed that the procedure examination abdomen ct scan in case of colecystitis at radiology installation Prof. Dr. Margono Soekarjo Purwokerto Hospital before the hearing preparation charge informed consent of patients, perform laboratory checks urium creatinin, fasting from the night and drank appoxcimately 1000 ml of Water the morning before the examination. While the position of the patient supine feet first and the administration of contrast media intra vena with a volume of 80 ml plus 20 ml Na Cl and arrangements flow rate 2,0 ml/sec with a scan delay of 40 seconds. Reason not to do engenering biphase technique examination in the case of abdominal CT Scan cholecystitis because only monophase technique, arterial phase alone can establish the diagnosis of cholecystitis.Conclusion: Information on CT Scan diagnosis in Radiology Installation  Prof. Dr. Margono Soekarjo Purwokerto Hospital was able to show in indication of cholecystitis but have not been able to show the mass and metastase to the surrounding organs lake the liver gallbladder and pancreas, intrahhepatic and extrahepatic tract.

Background: Axiolateral projection of mastoid examination with Schuller method using angle range of 25°-30° caudad according to Bontrager (2010). The difference thickness of the human’s head will cause range of angles of axiolateral projection of mastoid examination using Schuller projection. The inappropriate angle will affect the different anatomical information. Axiolateral projection of mastoid examination using Schuller projection in Radiology Installation of dr. Soetomo Hospital used an angle that is 25° for all patients with different thickness of the head. This study aims to determine the differences in anatomical image clarity on radiographic image of axiolateral projection of mastoid examination using Schuller method with an angle that is 25° with variations of head thickness between 12 to 14.5 cm.Methods: This research was a quantitative research with an experimental approach. Subjects of this reearch were 10 respondents. Data analyzed statistically by Kruskal Wallis test and Mann Whitney test.Results: The results showed that there was difference in anatomical image of axiolateral projection of mastoid examination with Schuller method with 25° angle. Result of statistical test to get optimal radiographic image of mastoid using Schuller method showed the significant value, which was 0,000. Differences in anatomical image was also shown on the assessment results from 10 respondents which most of respondents assess anatomical features on a 14.5 cm head thickness was very good.Conclusion: There were differences anotomical information of mastoid radiograph using schuller method with thickness variaton of head. Head thickness of 14.5 cm can show anatomical image of the mastoid air cells, bony labirinth, condyle mandible, temporomandibular joint (TMJ), Aacousticus the external meatus (MAE) and tegmen tympani. The CR angle should be considered based on head thickness.

Background : Parallel imaging is one of the MRI Scanning techniques used to reduce the overall scan time when the patients with unvoluntary movement being examined with a low magnetic field of 0,35 T.  This research aims to determine the difference between the clinical image quality of the conventional turbo spin echo (TSE) with mSENSE and that of the TSE with GRAPPA parallel imaging techniques from which resulting the MRI T1 and T2 Weighted Images (T1WI and T2WI) sagittal view of lumbar spines, and to define the techniques that clinically provide the most approriate anatomical information.Methods :  This experimental study is made performed by the MRI 0.35 T in which 10 patients who had hernia nucleus pulposus (HNP) desease participated in the experiments ramdomly. The appointed Radiologists blended in the image evaluation using an image checklist to assess the visualisation of anatomical organs on the resulted sagittal lumbar MRI T1WI and T2WI. The two non-parametric statistical tools, Friedman test and the post hoc Wilcoxon matched pairs test, is used to analyze all the data descriptively. Testing the resesearch hypotheses with 95% of confident interval is to proved the differences between resulted sagittal lumbar MRI T1WI and T2WI..Results : The results shown there is a significant difference on the image quality of anatomical information when conventional TSE, parallel imaging-mSENSE and -GRAPPA, with T1WI are applied in the imaging techniques. When those imaging techniques are employed to obtain T2WI, the result is not significant in  contrast.Conclusion : Good imaging techniques with adequate clinical image quality are ranked sequently as the conventional TSE, the  mSENSE and GRAPPA.

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 180 0 and 360 0. 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 Termoluminisencedosemeter (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 180 0 and 360 0. 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 180 0 , and with shielding 360 0 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 180 0 , and a decrease of 62.94% when shielded 180 0. Conclusion:Lead apron is effective for reducing radiation dose on breast in abdominal CT. 360 0 shielding provides higher reduction than 360 0 shielding, so it can be considered to be applied in clinical procedure.
