Snowboarders face different injuries from skiers
October 19th 2005Despite the image of young snowboarders recklessly bombing downhill, the popular sport actually has no greater percentage of injuries than does skiing. Snowboarders have their own types of injuries, however, related to factors unique to the sport.
Engineering innovation leads to first clinical PET/MR scanner
October 10th 2005Working with colleagues at the former CTI PET Systems in Knoxville, Siemens Medical Solutions engineers in Erlangen, Germany, are assembling a prototype PET/MR scanner designed to overcome technical barriers that have thus far kept a hybrid of these two modalities from clinical use.
Pancreatic imaging gets a taste of the tropics
October 7th 2005Could patients with possible biliary and/or pancreatic disease soon be offered a piña colada before imaging? Not quite, but a team of Belgian radiologists has started serving pineapple juice labeled with gadolinium to boost the quality of its MR cholangiopancreatography scans.
Perfusion-diffusion confusion yields to spatial information
October 5th 2005In recent years, the use of MR perfusion- and diffusion-based imaging to predict tissue outcome following acute ischemic stroke has increased significantly. While most strategies to improve outcome have focused on MRI parameters, researchers from Boston and Finland have devised a novel approach that also includes spatial information.
Glaucoma drainage implants and MRI safety
October 3rd 2005A drainage implant or device, also known as a tube shunt, is implanted in the sclera of patients with glaucoma to maintain an artificial drainage pathway and control intraocular pressure. Intraocular pressure is lowered when aqueous humor flows from inside the eye through the tube into the space between the plate that rests on the scleral surface and surrounding fibrous capsule.(1-3)
Functional MRI sniffs out liars and cheats
September 28th 2005TV cops are unlikely to visit their local MR center when extracting confessions from suspected criminals. But the appearance of 3T scanners on detective programs could simply be a matter of time, following research demonstrating the accuracy of fMRI-based lie detection.
Report from SMI: Dynamic MR imaging predicts responsiveness in rectal cancer patients
September 9th 2005New evidence presented this week at the 2005 Society for Molecular Imaging confirms that perfusion index measures obtained with dynamic contrast-enhanced MRI predict whether rectal cancer patients will benefit from chemoradiation.
7T scanners move closer to use in clinical research
September 1st 2005Philips and Siemens are delivering on promises made two years ago to develop ultrahigh-field MR systems. The companies are completing construction of several 7T clinical installations, each bearing the clinical front end of a mainstream MR scanner rather than the unwieldy controls that have marked previous installations. The ramifications for the MR community are enormous.
The ‘Celling’ of modern radiology
August 29th 2005Usually, the beginnings of great change are recognized only in hindsight. The exception to that rule may have happened Aug. 24. This was the day the developers of Cell Broadband Engine Architecture -- known informally as Cell -- flung wide the doors to the technical underpinnings of this new computing chip.
Cardiac MRA monitors pediatric heart surgery
August 18th 2005MR angiography can successfully monitor children who have had arterial switch surgery for transposition of the great arteries. Researchers in Belgium suggest the technique could spare children x-ray exposure from repeated exams and the potential toxicity of iodinated contrast agents.
Multispecialty partnerships adopt ablation therapies
August 12th 2005As more medical practitioners accept RFA and other tumor ablation methods for cancer treatment, physicians must determine how to integrate the procedure into their practices. The leap from academia to a clinical setting may be perilous, as tumor ablation doesn’t fit neatly into any one specialty. Does RFA belong in the interventional radiology box, the surgery box, or the oncology box?
Heart docs embrace new cardiac CT, MR guidelines
August 6th 2005Several cardiology societies have collaborated to update standards for training and utilization of cardiovascular CT and MR imaging, addressing increasingly burdensome credentialing requirements. The document applies only to cardiac applications and does not address extracardiac findings associated with cardiac imaging.
iPAT Squared offers big-time boost for 3T MR imaging
August 1st 2005Parallel imaging has gone exponential in Siemens' latest version of iPAT. The advanced iPAT Squared technology allows four, eight, or even 16 times the data capture of systems without parallel imaging, according to the company. There is a catch, however: Parallel imaging is a signal hog, and that can cause problems at all but the highest field strengths.
Vendors challenge limits of MR speed and resolution
August 1st 2005Parallel imaging is extending the limits of resolution with anatomic and functional studies of unprecedented clarity and diagnostic value. It is cutting acquisition times by more than half to freeze motion more easily and increase patient throughput.
ARRT toasts milestone, tweaks MR and ultrasound certification
July 18th 2005The American Registry of Radiologic Technologists in June celebrated its 250,000th certification. The ARRT might reach the half-million mark sooner than expected as it gears up to allow MRI techs and sonographers to be certified without first becoming radiologic technologists.
MRI promises to contribute greatly to cancer management
July 1st 2005The benchmark of any breast imaging tool is its ability to match mammography in cancer detection. Breast MRI not only holds its own in population subsets, it also promises to contribute more to breast cancer management than mammography can.
Metal detector safeguards against threats in MR suite
July 1st 2005Hospitals are full of the kind of metal that can change calm into chaos: patient carts, oxygen tanks, cleaning buckets. A momentary lapse or a step too close to an MR scanner can turn a mundane staple of hospital life into a lethal projectile.
Cardiac MR angiography monitors heart surgery children
July 1st 2005MR angiography can successfully monitor children who have had arterial switch surgery for transposition of the great arteries. Researchers in Belgium suggest the technique could spare children x-ray exposure from repeated exams and the potential toxicity of iodinated contrast agents.
Three-D imaging data aid neuronavigation
June 27th 2005Diagnostic radiologists may be growing familiar with interactive 3D imaging tools, but surgeons' acceptance has been slower. Further use of 3D imaging in the operating room is far from inevitable if surgeons remain unconvinced of the need for computerized anatomic reconstructions. Speakers at the CARS meeting effectively countered such skepticism by highlighting practical uses of 3D imaging data in neurosurgery.
Imagers await 3T endorectal coils for prostate exams
June 16th 2005Under the best of circumstances, 3T imaging of the prostate with a body coil can approximate the level of detail and sensitivity available at 1.5T with an endorectal coil. Researchers hope that with a 3T-oriented endorectal coil they will finally be able to take advantage of 3T's higher resolution in a challenging portion of the anatomy.
U.K. study strengthens case for breast MR screening
May 31st 2005A U.K. multicenter study has shown that a combination of MRI and mammography offers the best way of detecting breast cancer in women with a high genetic risk of the disease. The results add more weight to arguments for routine breast MRI for women carrying BRCA mutations and possibly for omitting mammography altogether
