New spectral imaging options improve abdominal CTA
By Eric Barnes
CT angiography (CTA) of the abdomen is a well-established method for answering any number of diagnostic questions, but in the past couple of years it's gotten even better. Recent technical advances, such as spectral imaging CT at different energy levels, can improve the modality's diagnostic power, reducing dose and contrast use.

Emergency departments reserve CT for complex cases
By Eric Barnes
The vast majority of CT exams of the abdomen and pelvis in U.S. emergency departments are ordered for clinically complex cases, suggesting that fears of CT overuse in simple clinical cases are largely unsupported, according to a study in the June Journal of the American College of Radiology.

CAD helps detect abnormal liver enlargement
By Erik L. Ridley
As quantitative imaging becomes increasingly important in radiology, automated tools such as computer-aided detection (CAD) software could play a vital role. A team from the U.S. National Institutes of Health has found that automated liver volumetry may help improve the detection of hepatomegaly, or abnormal liver enlargement.

ARRS: CT radiation far less risky than underlying disease
By Eric Barnes
The long-term risk of future cancers associated with CT scans has been under scrutiny for years, but those risks aren't remotely as serious as the risk of dying from the diseases CT is used to diagnose, concluded a study presented on Tuesday at the American Roentgen Ray Society (ARRS) meeting in Vancouver.

ARRS: CT useful when abdominal US is inconclusive
By Eric Barnes
About a third of CT exams performed after inconclusive abdominal ultrasound are positive, making CT a good choice for follow-up in many patients, researchers said on Monday at the American Roentgen Ray Society (ARRS) meeting in Vancouver.

NEJM: Low-dose CT good enough to diagnose appendicitis
By Eric Barnes
Low-dose CT is nearly equivalent to the standard-dose scan for diagnosing appendicitis, and it's accurate enough to serve as a first-line diagnostic modality while delivering less than one-fourth the radiation dose of full-strength CT, researchers report in a study published in the April 26 New England Journal of Medicine.
