Deep Learning to Detect Intracranial Hemorrhage in a National Teleradiology Program and the Impact on Interpretation Time.

The diagnostic performance of an artificial intelligence (AI) clinical decision support solution for acute intracranial hemorrhage (ICH) detection was assessed in a large teleradiology practice. The impact on radiologist read times and system efficiency was also quantified. A total of 61 704 consecutive noncontrast head CT examinations were retrospectively evaluated.

Forty-One Million RADPEER Reviews Later: What We Have Learned and Are Still Learning.

ACR RADPEER® is the leading method of radiologic peer review in the United States. The program has evolved since its inception in 2002 and was most recently updated in 2016. In 2018, a survey was sent to RADPEER participants to gauge the current state of the program and explore opportunities for continued improvement.

Diagnostic Error Categorization at Abdominal Imaging Peer Learning Conference.

Recognizing and preventing diagnostic errors is an increasingly emphasized topic across medicine, and abdominal imaging is no exception. Peer-learning strives for quality improvement through understanding why errors occur and identifying opportunities to prevent errors from recurring. In an effort to learn from mistakes, our abdominal imaging section initiated a Peer Learning Conference, where errors are discussed and compartmentalized into one or more of the following categories: Observation, Interpretation, Communication, and Inadequate Data Gathering.

The utility of scrotal ultrasonography in the emergent setting: beyond epididymitis versus torsion.

Scrotal pain is a common acute presentation for medical care. Testicular torsion and epididymo-orchitis are two diagnoses for which early detection is critical and their sonographic imaging features have been thoroughly described in the radiologic literature. Other important conditions for which radiologists must be aware have received less attention.

From esophagus to rectum: a comprehensive review of alimentary tract perforations at computed tomography.

Gastrointestinal (GI) tract perforation is a life-threatening condition that can occur at any site along the alimentary tract. Early perforation detection and intervention significantly improves patient outcome. With a high sensitivity for pneumoperitoneum, computed tomography (CT) is widely accepted as the diagnostic modality of choice when a perforated hollow viscus is suspected.

Characterizing solid renal neoplasms with MRI in adults.

Until recently, most solid renal neoplasms without macroscopic fat were presumed to represent renal cell carcinoma and were indiscriminately treated with nephrectomy. Expanding surgical options and ablative technologies, a growing acceptance of renal mass biopsy, the advent of targeted molecular agents, and advances in our understanding of tumor biology have challenged the wisdom of this approach and are ushering in a potential new era in which therapy is linked to histologic subtype and cytogenetics. This approach mandates evolution of our diagnostic algorithm beyond the distinction between solid and cystic and enhancing and nonenhancing.

Reducing radiation dose in CT enterography.

Computed tomographic (CT) enterography is a diagnostic examination that is increasingly being used to evaluate disorders of the small bowel. An undesirable consequence of CT, however, is patient exposure to ionizing radiation. This is of particular concern with CT enterography because patients tend to be young and require numerous follow-up examinations.
