VC goes extra innings with AAA screening
November 12, 2012 -- Virtual colonoscopy can do double duty by screening for abdominal aortic aneurysm (AAA), according to a study of more than 1,000 individuals. Researchers found that virtual colonoscopy was reliable for detecting AAA or, more commonly, for ruling out the condition.
MRI finds strokes are more frequent in kids with sickle cell anemia
November 12, 2012 -- Researchers using diffusion-weighted MRI to screen children with sickle cell anemia have found that acute silent cerebral ischemic events occur more frequently than previously thought, and a child with sickle cell anemia is at constant threat of ischemia.  Discuss
GE taps interest in ABUS with U-Systems acquisition
November 9, 2012 -- You know you're onto something when the big boys come calling. GE Healthcare has announced its acquisition of automated breast ultrasound (ABUS) developer U-Systems, a move that highlights the rapid evolution of ABUS from a niche technology into a promising adjunct to screening mammography.  Discuss
Hopeful VC symposium attendees set plans
November 9, 2012 -- After nearly two decades of promoting a colorectal cancer screening exam they believe is a better test than optical colonoscopy, virtual colonoscopy advocates have no illusions about the difficulties that have impeded their efforts to secure reimbursement for screening. But lately they're more hopeful of a real breakthrough.  Discuss
PET volume, glycolytic activity predict NSCLC local recurrence
November 9, 2012 -- By characterizing non-small cell lung cancer (NSCLC) tumors through glycolytic activity and FDG-PET volume after stereotactic body radiation therapy, clinicians may be able to detect which tumors are likely to recur, according to a study presented at the American Society for Radiation Oncology meeting.  Discuss
Speech recognition systems could detect signs of user stress
November 9, 2012 -- Many radiologists feel that speech recognition dictation systems -- one of the cornerstones of digital efficiency -- were thrust upon them. While the systems had the potential to dramatically reduce radiology report turnaround time and operating costs, their use has been burdensome to many radiologists by decreasing their productivity.  Discuss
Social networking gaffes can jeopardize residency applications
November 8, 2012 -- What you post on social media can hurt you, especially if you're applying for a residency or physician training program, according to a new BMJ study that surveyed personnel in charge of reviewing applications from potential medical residents and students.  Discuss
Admins hopeful about profit growth; Medicare, not so much
November 8, 2012 -- Radiology administrators are optimistic that in the coming months their facilities will grow and operating and staff costs will remain constant. But they remain less confident about Medicare reimbursement for diagnostic and interventional imaging, according to fourth-quarter 2012 data from the Medical Imaging Confidence Index.  Discuss
Facility-wide program cuts CT dose by up to 90%
November 7, 2012 -- A San Diego imaging center was able to reduce CT radiation dose by as much as 90% using a combination of dose reduction strategies with or without iterative reconstruction techniques, thus minimizing patient risk, researchers wrote in the November Journal of the American College of Radiology.  Discuss
Antidepressant rinse reduces pain for cancer patients after RT
November 7, 2012 -- When used as a rinse, doxepin, a tricyclic antidepressant, reduces oral mucositis pain in patients who receive radiation therapy (RT) for head and neck cancer, according to research from the Mayo Clinic presented at the recent American Society for Radiation Oncology annual meeting.  Discuss
