Prostate cancer CAD requires zone-specific techniques
By Erik L. Ridley
Location is everything. If recent research results are any indication, that old real-estate maxim also appears true for applying computer-aided detection (CAD) technology to the detection of prostate cancer.

SBRT halves cost vs. IMRT for prostate cancer
By Cynthia E. Keen
As members of Congress grapple over ways to reduce the U.S. budget, the publication on December 27 in the American Journal of Clinical Oncology of a complex model analyzing the costs of radiation therapy for prostate cancer seems particularly timely.

C-11 choline PET/MRI helps restage prostate cancer patients
By Wayne Forrest
A preliminary study by German researchers suggests that carbon-11 (C-11) choline PET/MRI may provide an alternative imaging modality to PET/CT for restaging of prostate cancer by offering equal, if not better, diagnostic performance and less radiation exposure.

Study finds CT radiation risk may be overestimated
By Eric Barnes
The risks from testicular cancer far outweigh the radiation risk from CT exams used to diagnose and monitor it, concludes a study published today in Radiology. While the study was limited to testicular cancer, it illustrates a common mistake being made in estimating the risk of radiation from medical imaging exams.

Is proton therapy worth the cost for prostate cancer?
By Cynthia E. Keen
Is the use of proton therapy for localized prostate cancer worth the cost? A national study of 30,000 men suggests it might not be. Findings were published online December 14 in the Journal of the National Cancer Institute.

Fused MRI, ultrasound aids prostate cancer detection
By AuntMinnie.com staff writers
Fusing MR and real-time ultrasound images to sample tumor spots can help detect and diagnose prostate cancer and, as a result, reduce the number of prostate biopsies, according to a study published online December 10 in the Journal of Urology.

Study: Hold the contrast for CT of asymptomatic hematuria
By Edward Susman
In young patients undergoing urograms after a finding of asymptomatic hematuria, it may not be necessary to perform contrast-enhanced CT, as a noncontrast scan may be sufficient, researchers suggested at last week's RSNA meeting.
