ATLANTA--In choosing the appropriate test, keeping clinical context in mind and understanding what the test indicates and what it does not indicate are key elements a physician must remember in selecting the correct imaging modality for the testing of myocardial viability, said Christopher Hanson, MD, professor of medicine and radiology at Thomas Jefferson University Hospital in Philadelphia, during an imaging symposium at the American College of Cardiology (ACC) annual conference on Monday.
A task force commissioned by the American Association of Physicists in Medicine (AAPM) has recommended that radiation dose delivered to the prostate and nearby organs in brachytherapy procedures should be carefully analyzed using post-implant CT or MRI and uniformly documented in each patient.
Researchers from Thomas Jefferson University and the University of Delaware in Newark have received a grant from the Department of Defense (DoD) to create a 3D patient imaging system that will allow surgeons to view and touch selected organs and tissues prior to surgery.
Walter J. Curran, Jr., MD, Radiation Therapy Oncology Group (RTOG) chair, has been named the executive director of the Emory Winship Cancer Institute in Atlanta, and associate vice president for cancer at Woodruff Health Services Center in Philadelphia.
It is now possible to identify head and neck cancer patients who have a higher risk of developing distant metastases or suffering a relapse, according to an early release of new research by Radiation Therapy Oncology Group (RTOG) investigators published online this week and in an upcoming issue of the Journal of Clinical Oncology.
Researchers from the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have implicated the loss of a stromal protein called caveolin-1 as a major new prognostic factor in patients with breast cancer, predicting early disease recurrence, metastasis and breast cancer patient survival, according to an article published online before print May 1 in the American Journal of Pathology.
An automated system designed for the interpretation of coronary CT angiography (CCTA) helps radiologists determine which cases are high priority and should be read first, according to a study presented today in Boston at the 2009 annual meeting of the American Roentgen Ray Society.

Physicians in states with medical liability tort reform laws ordered fewer imaging studies for emergency patients with mild-moderate head trauma, according to a study published July 13 in the online edition of the American Journal of Emergency Medicine.
The ability to transform healthcare delivery at the community level requires information and tools for both consumers and providers—not one or the other, said Aaron McKethan, program director for the Beacon Community Program under the Office for the National Coordinator for Health IT (ONC). McKethan discussed "Beaconology," an informal term used by ONC to describe the basics of the Beacon Program, in an exclusive interview yesterday.
An early morning radiologist shift can expedite the communication of urgent findings and improve patient care, according to a study in this month's Journal of the American College of Radiology. “The Joint Commission and the ACR have emphasized the importance of improved communication, particularly of critical test results, for better patient care,” Rathachai Kaewlai, MD, of Massachusetts General Hospital in Boston, shared with Health Imaging News.
Medical imaging overutilization--a growing concern in the U.S.--exposes patients to unnecessary radiation, while also adding to rising healthcare costs, according to a study published online Aug. 24 in Radiology. In an interview, William R. Hendee, PhD, lead author, reviewed various methods by which medical imaging could be curtailed.
Dedicated contrast-enhanced (CE) breast CT delivered significantly improved conspicuity of malignant breast lesions, including ductal carcinoma in situ (DCIS), compared with unenhanced breast CT and mammography, according to a study published in the September issue of Radiology.
Southern Methodist University (SMU) in Dallas has received a $596,000 grant from the National Institutes of Health’s (NIH) Neurological Disorders and Stroke Institute to study the role of ultrasound in determining the effects of radiation on bone.
