The dramatic growth of Medicare-related medical imaging utilization—which drew the attention of rate-cutting federal policymakers and the wrath of politicians on Capitol Hill in the mid-2000s—has ended, according to a study from Thomas Jefferson University in Philadelphia.

Cancer patients saw a four to five times greater increase in their average annual exposure to imaging-related ionizing radiation than the general population since 1994, according to a retrospective study of more than one million privately insured people in the U.S.

Radiologist errors identified from an analysis of 656 imaging exams paints a unique picture describing why radiologists make errors. The analysis also points to ways such mistakes can be prevented.

U.S. hospitals could save nearly $22 million annually by deemphasizing CT in favor of diagnostic ultrasound as the frontline imaging test for suspected appendicitis. Such a change would also spare many patients unnecessary exposure to ionizing radiation from CT, according to financial evaluation and meta-analysis by Laurence Parker, Ph.D., an imaging economics researcher at Thomas Jefferson University in Philadelphia.

A few modifications to the radiology order form can serve an important function in encouraging physicians to adopt evidence-based practices when ordering CT to evaluate small pulmonary nodules, according to a study from Dartmouth-Hitchcock Medical Center.

A Monday morning scientific session covering cardiac CT dose and noise broke down into newsworthy matched pairs: two studies examining the implication of CT radiation on public health, two investigating the impact of radiation reduction strategies on patient dose and image quality, and a third pair considering how noise reduction from iterative reconstruction affects the quality of images of highly calcified vessels and morbidly obese patients.

Dr. Hedvig Hricak used her presidential address before the opening session of the 2010 RSNA meeting to express her desire for a new molecular imaging subspecialty while cautioning radiologists that MI is not appropriate for all clinical settings.

A growing body of data is linking sportsrelated concussions to brain damage associated with cognitive impairment.

The brains of 24 retired U.S. National Football League players with known cognitive impairment show signs of damaging atrophy, according to advanced MRI studies described at the 2009 RSNA annual meeting.

In the aftermath of CT-related radiation accidents at the prestigious Cedars-Sinai Medical Center in Los Angeles, the FDA, healthcare providers, and manufacturers are taking action to avoid suffering through similar situations themselves.
