ACR Appropriateness Criteria® Staging and Follow-Up of Leukemia.

Imaging associated with staging and follow-up of leukemia can play an important role in accurately assessing disease; however, the type of imaging and usefulness varies significantly by the subtype of leukemia. This document reviews the current literature regarding the impact of imaging for both staging and surveillance of several of the most common leukemic variants. These include acute lymphoblastic leukemia, acute myeloid leukemia, chronic lymphocytic leukemia, Richter transformation, and chronic myeloid leukemia. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.
