Locating the preferred imaging modality
Extensive radiologic tools exist to aid clinicians in the diagnostic process. The AHRQ National Guideline Clearinghouse allows clinicians to search the American College of Radiology ACR Appropriateness Criteria® to locate suggested criteria for ordering radiologic exams.
Guidelines provide the suggested radiologic procedure that may be ordered for each presenting condition with a rating scale to denote the applicability for each exam. For each procedure the rating scale indicates the level of appropriateness of the exam. The guidelines also contain the relative radiation level for each type of exam.
Additionally, a summary of the literature is provided for the clinical condition in question. Examples of conditions described in the database include: osteonecrosis of the hip, assessment of fetal well-being, and nasopharyngeal carcinoma. Nearly 200 American College of Radiology Appropriateness Criteria are indexed by the AHRQ website to provide guidance in the ordering of radiologic exams.
