Intraoperative CT fine-tunes maxillofacial surgery
January 21, 2015 -- Maxillofacial surgeons who used CT intraoperatively on their trauma patients found that imaging and review can be performed quickly, perfecting the trauma surgeon's work while there's still time to make revisions, according to an article published this month in JAMA Facial Plastic Surgery.
US-guided biopsy performs well for evaluating bone neoplasms
January 21, 2015 -- Ultrasound-guided biopsy of bone neoplasms yields similar accuracy to CT-guided biopsy for evaluating primary and metastatic bone lesions, while saving money, offering patient convenience, and avoiding radiation dose, according to research from the Henry Ford Health System.
Joint Commission releases requirements for imaging services
January 20, 2015 -- The Joint Commission has released updated accreditation requirements for diagnostic imaging service providers in hospitals and ambulatory care centers. Although the new rules emphasize imaging safety in positive ways, more specific guidance is needed, according to safety advocates.
Practice of Ultrasound: Part 20 -- A great new year for ultrasound?

January 16, 2015 -- Thanks to a specially modified compact MRI scanner, Cincinnati Children's Hospital Medical Center is having early success in imaging infants in its neonatal intensive care unit for pulmonary ailments and abnormal lung development.
What do patients really know about radiation and radiologists?
January 16, 2015 -- While it's all well and good for radiologists to spend more time interacting with patients, it's important to understand what patients actually know about radiation and radiologists to do this effectively. Two studies presented at the recent RSNA meeting explored these questions and came to some surprising conclusions.
