May 23, 2017 -- A large analysis of pediatric head CT scans across the U.S. showed surprisingly large variations in radiation dose that increased as children

This data may be entered into the dose calculation form and the database will calculate the percent difference between the calculated CTDI vol and that reported by the scanner. Se hela listan på imagewisely.org 2017-09-19 · CTDIvol (or CTDI volume) represents the dose for a specific scan protocol which takes into account gaps and overlaps between the radiation dose profile from consecutive rotations of the x-ray source. Therefore CTDIw represents the average radiation dose over the x and y direction whereas CTDIvol represents the average radiation dose over the x, y and z directions. Effective January 1, 2008, the ACR program implemented United States-specific diagnostic reference levels of 75, 25, and 20 mGy, (CTDIvol) values for adult head, adult abdominal, and pediatric The ACR has initiated the Dose Index Registry leagues on the ACR CT Accreditation Committee for to automatically collect CTDIvol data directly from their many contributions to the program and this work, the Digital Imaging and Communications in Medi- including Drs.

for 13 noncardiac adult gamma camera and PET/CT ACR dose requirements were met for both genders in all BMI classifications. Dose metrics were higher in men than in women; median effective dose and CTDIvol were 1.39 (0.8-1.58) mSv and 2.78 (1.41-2.80) mGy in men versus 1.16 (0.71-1.43) mSv and 2.70 (1.4-2.78) mGy in women. Either include a screen save of the dose with the images, or enter the dose as displayed by the scanner in the Clinical Test Image Data Sheet.

Effective January 1, 2008, the ACR program implemented United States-specific diagnostic reference levels of 75, 25, and 20 mGy, respectively, for the CTDIvol of routine adult head, adult abdominal, and pediatric abdominal CT scans.",
