CT Chest, Abdomen, and Pelvis Without and With IV Contrast The majority of clinical questions for abdominal and/or pelvic CT can be appropriately answered with a single- phase study as detailed in the ACR-SABI-SPR practice parameter for the performance of CT of the abdomen and CT of the pelvis [21]. Imaging of Invasive Breast Cancer CT Chest, Abdomen, and Pelvis Without IV Contrast There is no evidence to support the use of CT chest, abdomen, and pelvis without IV contrast to evaluate for distant recurrence. FDG-PET/CT Skull Base to Mid-Thigh In symptomatic patients with a history of breast cancer who received treatment for curative intent, PET/CT can be used to evaluate for recurrence according to NCCN guidelines [126]. Imaging of Invasive Breast Cancer Supporting Documents The evidence table, literature search, and appendix for this topic are available at https://acsearch. acr.org/list. The appendix includes the strength of evidence assessment and the final rating round tabulations for each recommendation. For additional information on the Appropriateness Criteria methodology and other supporting documents go to www. acr.org/ac. Appropriateness Category Names and Definitions Relative Radiation Level Information Potential adverse health effects associated with radiation exposure are an important factor to consider when selecting the appropriate imaging procedure. Because there is a wide range of radiation exposures associated with different diagnostic procedures, a relative radiation level (RRL) indication has been included for each imaging examination. The RRLs are based on effective dose, which is a radiation dose quantity that is used to estimate population total radiation risk associated with an imaging procedure. Patients in the pediatric age group are at inherently higher risk from exposure, because of both organ sensitivity and longer life expectancy (relevant to the long latency that appears to accompany radiation exposure).
