PET/CT details hint at survival of head and neck cancer patients
By Wayne Forrest
Japanese researchers have found that several PET/CT parameters -- in particular, a ring-shaped area of FDG uptake -- are reliable predictors of survival for patients with head and neck squamous cell carcinoma. Results of their study were published in the April issue of the American Journal of Roentgenology.

IMRT confers survival benefit for head and neck cancer
By Brian Casey
Patients with head and neck cancer who received intensity-modulated radiation therapy (IMRT) had better survival rates than those who received conventional radiation treatment -- the first indication of a survival benefit for the more complex technique, according to a new study in Cancer.

Natural language processing predicts need for repeat head trauma CT
By Eric Barnes
Monday, December 2 | 10:50 a.m.-11:00 a.m. | SSC12-03 | Room N229When do head trauma patients need repeat CT scans? When the report suggests the condition is worsening. However, a neuroradiologist review is time-consuming, and scans are sometimes repeated unnecessarily. By automating the process, California researchers hoped to improve CT utilization and cut radiation exposures from unneeded scans in this study to be presented on Monday morning.
