From: Measuring appropriateness of diagnostic imaging: a scoping review
Appropriateness of MRI, CT, X-ray (XR) and ultrasound (US) in different body regions. The image shows the absolute number of studies and the accumulated number of reviewed examinations separated into different body regions. Based on the accumulated results, overall appropriateness (in %) was calculated presenting the span of study individual reported appropriateness in percent from lowest to highest. *Four studies reviewing the appropriateness of imaging other/miscellaneous body regions (CT + MRI) [64], heart/vessels CT [86], chest/breast CT [65] and whole body CT [89] reported the relative appropriateness without providing absolute numbers for different body regions.
