Abstract

Real time imaging allows a wide range of exposure than the conventional radiography for producing diagnostic images. Hysterosalpingography (HSG) is an effective method of evaluating abnormalities of the uterus and fallopian tube using real-time fluoroscopic procedure. The main purpose of this study was to assess the possible radiation dose deposited into different organs of female patients undergoing HSG during the reproductive period. The study was conducted at radiology department of Aminu Kano Teaching Hospital, Kano State, Nigeria. About sixty eight (68) number of patients with average age of thirty four (34) years, within the range of seventeen (17) to fifty (50) years were involved in the study. Patient’s weight and height were considered for the determination of Body Mass Index. The work took place between November 2017 to February 2018. Technique factors such as tube voltage (kV), tube current (mA) and time of exposure were compiled. Exposure of the X-ray machine in terms of μSv/mAs was measured using a Geiger Muller (GM) type detector. The findings of the study indicated that radiation doses received by patient’s organs varied significantly within the procedure. The urinary bladder received the highest dose of while the thymus received the least dose of . The patient-specific dose ranges from to . The mean effective dose was and the estimated lifetime attributable risk (LAR) cancer risk for HSG fluoroscopy-guided medically procedure was found to be 1.32×10–2 ± 0.001. The radiation doses deposited to the organs of patients involved in this study does not exceeds the limit and therefore imposed no threat.
