GI docs find value in virtual colonoscopy
May 31st 2006While radiologists have long supported virtual colonoscopy, their gastrointestinal colleagues have been skeptical. Research presented in May at the Digestive Disease Week meeting in Los Angeles suggests these clinicians are embracing the radiology technique.
Fusion imaging proves useful for RFA follow-up
May 25th 2006PET/CT provides reliable and accurate information on treatment response and disease recurrence for patients undergoing radiofrequency ablation treatment of primary and metastatic liver tumors, according to a series of studies by German researchers.
Hybrid MR/optical scanner examines breast tissue
May 25th 2006Dartmouth researchers have combined MR and near-infrared (NIR) imaging to form a hybrid breast scanner. The prototype, which has been tested successfully on volunteers and some breast cancer patients, is being groomed to detect early tumor growth and to stage tumors by characterizing their vascular and cellular makeup. By developing combined NIR/MR imaging, the researchers hope to evolve this hybrid into a mainstream modality for diagnosing breast cancer and following the treatment of patients.
FDA clearances dip in April, but show industry strength
May 24th 2006FDA clearances dipped in April compared with their spike in March, but the latest month put the industry back on track with previous years’ performance, outshining five of the past six Aprils with 28. That brings the total to 80 clearances this year -- in the ballpark with, though still lagging behind, industry performance since 2000.
Large trial boosts vertebroplasty’s worth
May 22nd 2006A Mayo Clinic study has proved that vertebroplasty can provide enduring relief from the disability and pain produced by spinal compression fractures. The data come from what may be the longest follow-up trial for vertebroplasty featuring the largest population sample ever recorded by a single institution performing the procedure.
Studies at 9.4T explore safety issues for lower fields
May 18th 2006The first human brain images done at the University of Minnesota’s 9.4T MR scanner are yielding impressive results, according to J. Thomas Vaughan Jr., Ph.D., who administers the Engineering Core of the Center for Magnetic Resonance Research at the U of M.
Goat study cements vertebroplasty's efficacy status
May 15th 2006Vertebroplasty appears to be safe for people in their golden years. But as the range of applications expands and the age of eligibility grows ever younger, will the procedure materials stand the test of time? A study of goats suggests they will.
Researchers confront strengths, limitations of 64-slice CTA
May 15th 2006State-of-the-art 64-slice CT is proving its worth as a potent noninvasive tool for imaging coronary arteries, but it has some noteworthy limitations, according to research presented at the European Congress of Radiology in March.
New MR regulations spur industry backlash, lobbying effort
May 15th 2006European radiology staff, medical imaging researchers, and manufacturers are being urged to lobby against regulations that will restrict the operation of MR scanners. Speakers at the European Congress of Radiology expressed concerns that the limits, to be imposed in all European Union member states by April 2008, have no scientific basis and could bring greater risks to patients.
MR imaging illuminates elbow joint disorders
May 15th 2006The elbow is a complex joint. It links the shoulder and the hand, enhances the flexibility of hand motion, and transmits generated forces. The most common elbow injuries are related to chronic overuse, although the joint is vulnerable to acute trauma as well.1 It may also be affected by disease or infection.
