Entrance Skin Dose and Effective Dose Measurement in The Most Common Diagnostic Radiology Examinations in Jiroft, 2017

Medical uses of radiation have grown very rapidly over in the past two decades, medical uses represent the largest source of exposure to people. Using diagnostic radiology devices is one of the most common and important methods in medical diagnosis. Although the use of these methods is very beneficial for the treatment of patients, ionising radiation may cause damage to the cells in living cells. The main purpose of this study was to investigate patient dose in common radiographic examinations. This study was performed in radiology centers and hospitals affiliated with Jiroft University of Medical Sciences, including QalehGanj Hospital, Imam Khomeini Hospital, Kashani Hospital and 12th Farvardin Kahnoch Hospital. In each center, measurements are performed on at least 10 patients aged between 25- 60 years for different imaging techniques including: Chest (PA), Pelvic (AP), Abdomen (AP), Skull (AP) and (LAT), Lumbar Spine (AP) and, Lumbar Spine (LAT). ESD, ED were measured with T-LD 100 and PCXMC software, respectively. The average entrance skin dose (mGy) and effective dose (mSv) for the Chest (PA), Abdomen (AP), Pelvice (AP), Lumbar Spine (AP) and Lumbar Spine (LAT) and Skull (AP) and Skull (LAT) were(0.63-0.06), (2.34-0.32), (2.48-0.39), (3.33-0.34), (7.32-0.17), (2.9-0.02) and (1.81-0.01) respectively. The values indicate that the implementation of quality control and quality assurance programs in the radiology centers is necessary and according ALARA principle all radiographic exams should be performed under lower doses with best quality of image.
