Study finds U.S. nuclear cardiology doses are too high
By Eric Barnes
Radiation doses for myocardial perfusion imaging exams in the U.S. are significantly higher than those in the rest of the world. Few U.S. sites adhere to best practices for dose reduction, and the U.S. fee-for-service model also contributes to the disparity, according to articles published online December 28 in JAMA Internal Medicine.

Optical imager targets breast cancer screening
By Medicalphysicsweb
Diffuse optical imaging has been proposed as a nonionizing and relatively inexpensive alternative method for detecting breast cancers, including those in dense tissues. Now, U.S. scientists have developed a handheld optical scanner with the potential to image breast cancer in real-time.

Study finds benefits to breast cancer screening over 75
By Kate Madden Yee
A new study of breast screening in women older than 75 has found that enough cancers are detected in this population to make screening worthwhile. The findings could shape the ongoing debate over whether older women should undergo regular screening.

Raman imaging steps closer to the clinic
By Jude Dineley
For brain tumor patients undergoing surgery, the proportion of tumor removed is a major factor determining prognosis. However, diseased tissue may look like healthy brain, making it difficult for surgeons to locate the tumor margin.

Density mapping predicts interval breast cancers
By Eric Barnes
Dutch researchers are using a breast density mapping software package to predict which density patterns are associated with higher rates of tumors found between mammography screenings. The results may help make supplemental breast cancer screening exams more effective for select patients.

PET features help guide dose escalation
By Cynthia E. Keen
Quantitative imaging features (QIFs) from FDG-PET combined with conventional prognostic factors of patients with non-small cell lung cancer (NSCLC) show potential to enhance overall survival risk stratification. That's the conclusion of study findings published in the Red Journal and Radiology.

fMRI finds the Christmas spirit alive and well
By Wayne Forrest
If there was ever any doubt about the existence of the Christmas spirit, one need only look into certain regions of the human brain. That's according to Danish researchers, who found that specific areas of the brain lit up on functional MRI (fMRI) scans when people who celebrate the holiday viewed Christmas-related imagery.
