MDCT: 3 things to do to standardize CT radiation dose
June 8, 2015 -- SAN FRANCISCO - Even the largest and most unwieldy collection of CT scanners in a multisite institution can function as one by standardizing three simple components of their CT scanning protocols, according to a Sunday presentation at the annual International Symposium on Multidetector-Row CT (MDCT).
SNMMI: PET/CT predicts survival in head and neck cancer
June 8, 2015 -- BALTIMORE - FDG-PET and FDG-PET/CT do a good job in predicting the chances of recurrence and survival for patients with head and neck cancer within two years of completing chemotherapy treatment, according to a study presented on Sunday at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) annual meeting.
Mobile App Spotlight: Cincinnati Children's Hospital
June 8, 2015 -- presents the next article in an ongoing series highlighting notable mobile apps in radiology. In this installment, we take a look at the CincyKidsRad hospital account on Figure 1, a popular medical image sharing community, that's run by the department of radiology at Cincinnati Children's Hospital Medical Center.
Ind. radiology group institutes flat-rate pricing
June 5, 2015 -- A radiology practice in Indiana has come up with a unique response to patient confusion about medical imaging costs: a flat-rate pricing program that offers set rates for various imaging exams, regardless of whether patients have insurance.
Adding contrast to CT doubles DNA damage from radiation
June 5, 2015 -- Patients who received contrast with their CT scans had more than twice as many double-strand breaks in their DNA from radiation exposure compared to those who had CT studies without contrast, concludes a new study in the June edition of Radiology. But whether this DNA damage translates into cancer risk is unclear.
New CAD app generates radiology reports
June 5, 2015 -- Researchers from Oregon have developed a novel computer-aided detection (CAD) application for radiology reports -- one that churns out differential diagnoses, accurately drawing correlations between imaging findings and potential disease states, according to a presentation at the Society for Imaging Informatics in Medicine meeting.
Canadians cut CT dose by scanning larger regions
June 4, 2015 -- Researchers from Canada were able to cut radiation dose in CT studies of multiple anatomic regions with a simple solution: performing a single scan with a larger field-of-view, rather than combining two scans of smaller regions. The technique eliminated overlap in CT dose, according to data presented at a joint meeting of Canadian radiology societies.
ISMRM 2015: DCE-MRI predicts response to breast chemo
June 4, 2015 -- TORONTO - A new method of dynamic contrast-enhanced (DCE) MRI is an "excellent early predictor" of treatment response and a good marker of residual cancer burden during and after neoadjuvant chemotherapy for breast cancer, according to a study at the International Society for Magnetic Resonance in Medicine (ISMRM) meeting.
New high-res 3D MRI map aids surgeons
June 4, 2015 -- Researchers at Duke University have created an ultrahigh-resolution 3D MRI map of the human brainstem, intended to help surgeons use deep brain stimulation to treat patients.
NEJM: Breast cancer screening reduces mortality by 40%
June 3, 2015 -- Another salvo in the screening mammography wars has been released in the form of a literature review in the New England Journal of Medicine suggesting that breast cancer screening reduces mortality by 40%. Both sides of the breast screening debate may be able to gain ammunition from the report's findings, however.
