Radiation therapy for prostate cancer linked to secondary cancers
By Cynthia E. Keen
Patients undergoing external-beam radiation therapy (EBRT) for localized prostate cancer may be at an increased risk for secondary malignancies 10 or more years after initial treatment. French-Canadian men who received EBRT between 1983 and 2004 were found to have a higher prevalence of bladder, rectal, and lung cancers compared to those who had a radical prostatectomy.

Experience is key to fewer errors in radiograph interpretations
By Wayne Forrest
A new study from the University of Iowa Carver College of Medicine found that the error rate for radiograph interpretations will decrease with experience and, predictably, first-year residents have the highest rate of missed diagnoses. One interesting note from the study, however, is that first-year board-certified radiologists had a major error rate similar to that of experienced board-certified radiologists.

Coronary calcium still matters
By Eric Barnes
In light of radiology's fervent focus on coronary CT angiography (CTA) and unstable coronary artery plaque, does coronary artery calcium even matter anymore? It does, according Dr. J. Jeffrey Carr of Wake Forest University in Winston-Salem, NC. He recently debunked some myths about calcium at the 2008 International Symposium on Multidetector-Row CT.

Automated polyp measurement cuts variability
By Eric Barnes
A new study from the Netherlands found that manual polyp measurements in virtual colonoscopy were a bit more accurate than an automated process based on polyp protrusion measurements. The automated scheme still came out ahead, however, because it eliminated interobserver variability.

Low tube current, modulation reduce pediatric CTA dose
By Eric Barnes
Dialing down the x-ray tube current and activating tube-current modulation made a huge difference in the radiation dose for children undergoing coronary CT angiography (CTA), according to a new study in the American Journal of Roentgenology. The reduced-dose acquisition protocols had no significant negative effect on image quality and were, in fact, hardly noticeable, researchers said.
