Abstract

X-ray cassette is a light-tight container to cover radiographic film during radiographic examination. Cassette can directly or indirectly contact with the patient’s body. It can be a spreading medium of bacteria from patient to patient, or patient to radiographer. The aims of this study are to determine the number of microorganisms contained in the cassette before and after cleaning, and to know the difference between those two numbers. The study is an observational study with cross-sectional approach. The survey was done to 17 cassettes to measure the number of bacteria using swap method. Then, the data were analyzed using Wilcoxon test. Result shows that the mean of bacteria, fungi, staphylococcus and ALT on cassettes before cleaning was larger than the mean after cleaning the cassette using 70 % alcohol. The Wilcoxon test in bacteria, fungi, staphylococcus and ALT showed ρ = 0.0001, 0.012, 0.0001 , 0.0001 < 0.05 means that there was a significant difference in the content of bacteria, fungi, staphylococcus and ALT before and after cleaning the cassette using alcohol 70%. Based on these results the cassette should be cleaned regularly every morning to avoid the possible spread of bacteria.

Abstract

This research is a descriptive study with quantitative and qualitative approaches. Data were obtained from five Clinical Practice Hospitals with Focused Group Discussion. Data were analyzed with descriptif Method. The result shows that the radiographers tend to use higher Expossion Factor and Wider Collimation Field. because the Vendor and Aplicant has informed that CR operation need higher energy and the appearance of noise when the image being manipulated in CR will be lower if high mAs and kV are used. Another affecting factor is prefer images with high density. Radiographers tend to use wider Collimation Field to prevent image cut-off, resize-able image in CR, and availability of widest Imaging Plate size (35x43). Based on that results, optimal exposure factor and precise collimation field should be used in CR in order to minimize the patient dose.

Abstract

Most of the students got difficulties in comprehending narrative reading texts. It could be seen from the result of exams given by teacher. Thus, this study is aimed at finding out (1) To what extent Small Group Discussion could improve the students’ reading comprehension on narrative text at tenth grade MA KMI of Diniyyah Puteri Padang Panjang and (2) What factors could influence the students’ reading comprehension of narrative text by applying small group discussions. The Classroom Action Research (CAR) has been conducted in three cycles. The participants were twenty three students of class X A MA KMI of Diniyyah Puteri. The data were collected by giving reading comprehension tests, observation, interview and field notes. They were analyzed quantitatively and qualitatively. The findings have shown that (1) Small Group Discussions could improve students’ reading comprehension of narrative text at class X A MA KMI Diniyyah Puteri Padang Panjang, and (2) factors which influence students’ reading comprehension were limited number of students, reading materials and giving rewards to increase students’ participations and motivations, monitoring and group discussion activities.

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.

Abstract

Pemeriksaan MRI humerus menggunakan body coil sering ditemukan artefak aliasing. Terdapat dua cara untuk menghilangkan artefak aliasing yaitu  dengan pengaturan frequensi encoding direction dan phase oversampling. Tujuan penelitian untuk mengetahui perbedaan artefak aliasing pada gambar MRI humerus dengan menggunakan body coil dalam variasi pengaturan frequensi encoding direction dan phase oversampling serta menentukan pengaturan terbaik frequensi encoding direction dan phase oversampling. Penelitian adalah eksperimental one shot case study. Variasi frequensi encoding direction adalah head to feet dan feet to head sedangkan phase oversampling adalah 0%, 50% dan 100%. Penilaian gambar dari 16 volunteer dilakukan oleh dokter spesialis radiologi meliputi kejelasan artefak aliasing. Data dianalisis menggunakan uji Friedman dilanjutkan uji Wilcoxon pada tingkat kesalahan 5%. Ada perbedaan artefak aliasing gambar MRI humerus menggunakan body coil dengan variasi pengaturan frequensi encoding direction dan phase over sampling dengan nilai p < 0,001. Frequensi encoding direction head to feet pada phase oversampling maksimum menghasilkan gambar yang paling baik. Ada perbedaan artefak aliasing gambar MRI humerus menggunakan body coil dengan variasi pengaturan frequensi encoding direction dan phase over sampling. Gambar terbaik diperoleh dengan frequensi encoding direction head to feet dan phase oversampling 100%.
