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.

Size-specific subgroup analysis revealed a wide variability of SSDE and CTDIvol across CT protocols and patient size groups with a transgression of DRLs in noncontrast abdominopelvic CT of large patients (Dw 37–41 cm). 2020-07-30 · DIR Executive Summary and QCDR Preview reports provide aggregate data for your facility compared to the entire registry.

CT dose index (CTDI) (measured in mGy) is a standardized measure of radiation dose output of a CT scanner which allows the user to compare radiation output of different CT scanners. In the past CTDI100 (measured over a 100 mm long ionization cham

The facility will not receive a pass if the radiation dose is perceived to be too high, regardless of ACR CT dose metrics requirement for CTDIvol of 3.0 mGy for a standard size normal BMI patient was still met in our population for all groups of patients including the obese. The CT dose metrics in our patient population were considerably lower than the mean national average CT dose metrics data for all CT lung cancer screening examinations that 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.", 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. Mark Armstrong, James Brink, Bolivia cine (DICOM) header, thus allowing The aim of this study was to assess the distribution of CT dose index (CTDI) values reported by sites undergoing ACR CT accreditation between 2002 and 2004. The ACR CT accreditation program uses diagnostic reference levels (and pass-fail criteria) as follows: CTDI vol of 75 mGy (pass-fail criterion, 80 mGy) in the 16-cm phantom for a routine adult head examination, 25 mGy (pass-fail criterion, 30 mGy) in the 32-cm phantom for an adult abdomen examination, and 20 mGy (pass-fail criterion, 25 mGy) in CT dose index (CTDI) (measured in mGy) is a standardized measure of radiation dose output of a CT scanner which allows the user to compare radiation output of different CT scanners.

2003 data now specifies CTDIvol reference levels of 65 mGy for the cerebrum and 100 mGy for the posterior fossa). Thus, the ACR CT Accreditation Program used survey data from the inception of the program to establish the most current U.S. reference levels for head CT (i.e., 2002 data were used to avoid including dose 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.
