Abstract

AIM OF THE STUDY: To compare the dose difference and state the significance of Automatic Tube Current Modulation (ATCM) in abdominal MDCT examination while maintaining optimum image quality for diagnosis. Results: The varying in MAS values according to ACS for different body counter of the patients was observed. In group A resulted in estimations of dose saving in range of 10-27 %.In group B 8.1-36.6 %, in group C 8.3-33.4%, group D 5.7-19 % with application of ATCM technique. The overall radiation output results shown for forty patients as follows the least is 5.7% and highest is 36.6%.According my study statistics shows there is no correlation between BMI and the estimated dose savings. • Radiation Dose reduction Up to 36.6% was achieved with acceptable diagnostic image quality. • Reduces over all irradiation time. • Helps in reduce stochastic and genetic effects. • Helps in Not only reduce the patient dose as well as occupational dose. • Scan duration is less compare to standard protocol so we can save the time at clinical side. • Effective in breath hold scans (Coronary Angio, Pulmonary Angio, Thorax and Abdomen). • Required dose is applied according to patient body counter. • Helps in decrease scan time in uncooperative and trauma patients. • I conclude that according to the observed results. Aim of the study To compare the dose difference and state the significance of Automatic Tube Current Modulation (ATCM) in abdominal MDCT examination while maintaining optimum image quality for diagnosis. Conclussion The use of Automatic Tube Current Modulation (angular dose modulation and z-axis dose modulation) helps in
