| dc.description | Optimizing scanning technique in CT (lowering kV, mA and exposure time, increasing slice thickness and limiting the scan range to only necessary anatomy) the aim of our study are Comparison of Radiation Dose and Image Quality between 16-64 MDCT. 84 patients included in this study divided to 4 groups21patients were in each Group, The parameters were examined kV 120, the mAs values were degraded from 200 to 400 mAs , The slice thickness were 2mm for 16MDCTgroup(1) and 3mm16MDCT group(2), 2mm 64CTMD group(3), and 3mm for 64CTMD group(4). The results illustrated the comparisons of radiation doses for each group were obtained at 200 mAs , There was no significant difference between the group (1) and group (2) , also between group (3) and group (4) .The CTDIvol in Group (1) was 32.17mGy in group (2) was 32.17mGy , while the DLP group (1)was 564.1mGy.cm in group (2) was 560mGy.cm. The CTDI vol in group (3) was 22.9 mGy in group (4) was also 22.9mGy while the DLP group (3) was512.9 mGy.cm and group (4) was 510.6 mGy.cm and at 350 mAs , The CTDIvol in Group (1) was 56.31mGy in group (2) was 56.31mGy , while the DLP group (1)was 987.2mGy.cm in group (2) was 981.6mGy.cm. The CTDI vol in group (3) was 39.95 mGy in group (4) was also 39.95mGy while the DLP group 3 was897.6mGy.cm and group (4) was 893.6 mGy.cm, Through the results we noted there are higher significant a difference between group (1-2)more than group (3-4) .In this study ,we mad questionnaire for the team of many radiology departments where the radiographic images presented by known image's parameters, The aim of the questionnaire was to select the better image, the most radiologists they were 9form11(81.82%) chosen the group (4) MDCT64 3mmslice thickness at 250 mAs and 120 kV was the best images depended on radiation image quality with less exposure radiation dose. | |
