CT has been the source of half of the medical radiation that patients are exposed to, making it a significant contributor to current radiation levels1. Radiation dose in computed tomography (CT) has become a hot topic due to the upgoing bar of no. of CT procedures and relatively high doses associated with these procedures. The effective dose 'ED' for each patient varies depending on the organ segment being imaged, as well as the patient's gender and age. The objective of our study is (a) to...

After IRB approval, 300 cases of Plain abdominal KUB CT of patients, aged above 18 years of either gender met the inclusion criteria and comprised the study population at our Institute from November 2020 to May 2021. It was a retrospective cross-sectional-analytical study with consecutive non-probability-sampling technique. Tri-phasic CT abdomen scans were excluded because of being a multiphasic phase study and it quadruples the dose. CT head, CT chest, or extremities were also excluded to avoid the complexity of data. 50 cases were eliminated while...

A total of 300 patients of either gender with age between 18-88 years were taken in the current study. The mean age of study subjects was 39.74±15.11 years while the median age of study subjects was 37 (IQR: 28-50) years. There were 64% (n=192 males) and 36% (n=108 females). The baseline characteristics were compared between two CT (16-slice versus 128-slice) scanners. The median age of study subjects was 38 (IQR: 30-55) years in 16-slice scanner type while 35 (IQR: 26-46.25) years in 128-slice scanner type...

This study from technical point of view was a Quality assurance project for CT Dosimetry and was conducted as a research activity for undergraduate radiology technologist trainees, to make them familiarize with CT parameters. The current study was strengthened by the adequate sample size and would solve the reader's queries regarding the radiation hazards and coverage of CTDI Metrics would serve as a revision for Radiologists. Our study proves that the difference in slice number of the scanners doesn’t affect the amount of radiation exposure...
