ACR Appropriateness Criteria® Vision Loss
Vision loss is a common medical problem that can arise secondary to a variety of pathologies including trauma, ischemia, infection or inflammation, demyelination, and mass lesions anywhere along the visual pathway. Most nontraumatic pathology to the globe is diagnosed by ophthalmologic examination and does not require imaging. When needed, the choice of imaging study is directed at the known or suspected cause and the expected anatomic location of the insult along the visual pathway. This docume…

Assessing deep learning artificial intelligence support for detecting elbow fractures in the pediatric emergency department
Elbow fractures are among the most common pediatric injuries, accounting for 15–20 % of all fractures in children [1,2]. Diagnosing these fractures can be particularly challenging due to the complex radiographic appearance of the developing elbow, which features multiple ossification centers that emerge at different stages [3,4]. As a result, identifying fractures often requires recognizing indirect signs, such as the fat pad sign, which suggests joint effusion [5–7]. Accurate diagnosis is criti…

ACR Appropriateness Criteria® First Trimester Vaginal Bleeding: 2025 Update
Vaginal bleeding is a relatively common occurrence in the first trimester of pregnancy, but can be distressing for both patients and clinicians. Differential considerations include normal intrauterine pregnancy (IUP), a nonviable IUP, an ectopic pregnancy (EP), or much less commonly gestational trophoblastic disease (GTD). Although the diagnosis of EP, nonviable IUP, and GTD is important, it is also crucial to avoid harming potentially normal pregnancies through early medical or surgical treatme…

ACR Appropriateness Criteria® Horner Syndrome
Horner syndrome is a combination of signs and symptoms caused by abnormalities in the oculosympathetic pathway. Typically, patients present with ipsilateral miosis, ptosis, and anhidrosis. Imaging the oculosympathetic pathway is complex because of its extensive course, need for targeted protocols, and the wide range of pathology that can cause it. For this document, we focus our attention on workup guidelines based on clinical features: 1) acuity (acute, nonacute including chronic, insidious, an…

ACR Appropriateness Criteria® Hematospermia
Hematospermia is an uncommon source of referral for imaging. When considering the adequate modalities for its evaluation, the patient’s age, duration, and associated symptomatology need to be taken into consideration. Younger patients with transient hematospermia and without associated signs or symptoms usually require a clinical approach and reassurance. In the setting of symptomatic hematospermia, persistent hematospermia, and in older patients, imaging may be indicated to assess for possible …

ACR Appropriateness Criteria® Management of Acute Pulmonary Embolism
Acute pulmonary embolism (PE) is a subclass of venous thromboembolism, which can be associated with significant morbidity and mortality. Risk stratification algorithms classify PE into high-risk (massive), intermediate-risk (submassive), and low-risk groups, with management guidelines determined based on clinical risk. For high-risk PE, first-line treatment options may include anticoagulation, systemic thrombolysis, catheter-directed therapies, and surgical embolectomy. For intermediate-risk PE,…

ACR Appropriateness Criteria® Male Breast Cancer Screening
Breast cancer screening recommendations have been established historically for women, but, have been less clearly outlined for men. For average-risk men and younger men less than 25 year of age, imaging is not usually appropriate as a screening test for breast cancer. For men of higher-than-average risk, screening with mammography as annual surveillance imaging is usually appropriate.The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical co…
