A Qualified Medical Physicist should meet the ACR Practice Guideline for Continuing Medical Education (CME). (ACR Resolution 17, 1996 – revised in 2008, Resolution 7) CME should include education in radiation dosimetry, radiation protection, and equipment performance related to the use of medical imaging.

Recommended Screening Population The median CTDIvol did not vary significantly but DLP increased with lateral thickness for head exams. For neck and c-spine, the median CTDIvol and the 75th percentile did not vary significantly but the median DLP did with effective diameter. Similar trends were seen for the median CTDIvol and SSDE for chest, abdomen and chest-abdomen-pelvis exams.

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 American College of Radiology, with more than 30,000 members, is the principal organization of radiologists, radiation oncologists, and clinical medical physicists in the United States. head CT (U.K. 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. The ACR recommends that the payment rate of CPT® code 71250 (Computed tomography, thorax; without contrast material) should serve as the reimbursement floor for LDCT lung cancer screening with additional RVUs assigned for the numerous quality criteria required of an effective lung cancer screening program and mandated in CMS’s final coverage decision.
