Minimal or no padding can reduce radiation dose during ECG-triggered coronary CTA

Reduced or no "padding" during ECG-triggered coronary CT angiography (CTA) results in a substantial reduction in radiation dose without affecting image quality and interpretability, according to a study in the April issue of the American Journal of Roentgenology. ECG-triggered coronary CTA is a common, minimally invasive procedure that is used to evaluate blockages in the coronary arteries.

Dual-energy CT helps diagnose gout reliably in acute, emergency settings

A medical imaging technique called dual-energy computed tomography (CT) is an effective and reliable way to diagnose gout in the acute, emergency setting, according to a study published in the April issue of the American Journal of Roentgenology. Dual-energy CT is an advanced medical imaging technique that can detect vessels and bones and display them in clear contrast to one another. It enables physicians to diagnose many patients' conditions faster and more accurately as it can better characterize tissue composition better than conventional CT.

Radiofrequency ablation helps prolong life of colorectal cancer patients

Approximately half of Americans living with colorectal cancer will develop liver metastases at some point during the course of their disease. Radiofrequency ablation, a minimally invasive treatment that applies heat directly in the tumor causing cancer cell death with minimal associated injury to the surrounding healthy liver, contributes to prolongation of their life by nearly three years, note researchers at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla.
