Feature: U.S. needs national strategy to curb imaging overutilization

Medical imaging overutilization--a growing concern in the U.S.--exposes patients to unnecessary radiation, while also adding to rising healthcare costs, according to a study published online Aug. 24 in Radiology. In an interview, William R. Hendee, PhD, lead author, reviewed various methods by which medical imaging could be curtailed.

Radiology: Prelim study shows CE breast CT outperforms CT, mammo

Radiology: Rad role may evolve as image-guided biopsies trend up

CT, ultrasound and MRI have helped shift biopsy techniques away from more invasive approaches toward image-guided percutaneous techniques, according to a study published in the September issue of Radiology. The trend toward less-invasive approaches translates into enhanced safety and efficiency and could lead to more interaction between patients and radiologists.

CMS Webinar: Incentive payments to offset EHR adoption, not reimburse
