4 applications of cinematic rendering in maxillofacial CT

By Abraham Kim

Swiss researchers have used cinematic rendering to create photorealistic images of head CT and conebeam CT scans. They assess the potential benefits of integrating these images into the evaluation of maxillofacial anatomy and pathology in a study recently published online in Dentomaxillofacial Radiology.

Head CT offers low diagnostic yield for fainting

By Abraham Kim

More than half of all patients who faint still undergo head CT despite a diagnostic yield of less than 3% for the exam, according to an article published in the May issue of Academic Emergency Medicine. Researchers from Canada say it's high time to cut back on using the test for most patients.

ARRS: Use of CT angiography surges for carotid imaging

By Abraham Kim

HONOLULU - The utilization rates of all imaging modalities for noninvasive carotid imaging have declined over the past decade with one exception -- CT angiography (CTA). CTA use for carotid imaging has grown by nearly 700%, according to a presentation on Monday at the American Roentgen Ray Society (ARRS) meeting.
