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. CONCLUSSION: The use of Automatic Tube Current Modulation (angular dose modulation and z-axis dose modulation) helps in  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 there is no requirement to
