Virtual colonoscopy wins recognition as most cost-effective screening tool
April 23rd 2007Physicians’ pursuit of the subtlest signs of cancer may be misplaced when it comes to colon cancer. Finding lesions 5 mm or smaller does not significantly reduce the incidence of colorectal cancer, according to study results scheduled for the June 1 issue of Cancer, a peer-reviewed journal of the American Cancer Society. The results, published online April 23, are good news for virtual colonoscopy.
Novel CT contrast agent targets vulnerable plaque
April 11th 2007N1177, an experimental contrast agent plucked from a foundering company, has researchers at Mount Sinai School of Medicine high on its potential for use in coronary CT angiography. The agent’s propensity to accumulate in coronary plaque rich in macrophages shows promise for identifying patients at high risk of heart attack and stroke. CT angiograms then highlight this plaque, which is especially vulnerable to rupture, putting its bearers at increased cardiovascular risk.
Asian nations use UN cash to strengthen PET facilities
April 1st 2007Thailand, Malaysia, and other countries have received United Nations aid to implement and upgrade their PET and nuclear medicine capabilities. The nuclear medicine section of the International Atomic Energy Agency, a UN affiliate organization, provides the assistance as part of its mandate to foster peaceful uses of nuclear science and technology.
Details emerge from use of 256-slice CT at Johns Hopkins Medicine
March 27th 2007Several weeks of clinical tests at Johns Hopkins Medicine have confirmed expectations for Toshiba’s 256-slice CT, establishing the prototype’s ability to measure subtle changes in blood flow and minute blockages in the heart and brain.
Experts pinpoint benefits of hybrid systems in cancer management
March 13th 2007Correct diagnosis of tumor character and stage is fundamental to lung-cancer therapy planning, but evaluating indeterminate solitary pulmonary nodules (SPNs) continues to challenge radiologists. In addition, it is vital to determine as soon as possible whether patients are likely to respond to treatment.
CTA revolutionizes treatment of peripheral vascular disease
March 1st 2007We continue to be both amazed and intrigued by the hype showered on cardiac CT angiography and the corresponding lack of hype given to peripheral vascular CTA. No doubt, 64-slice cardiac or coronary CTA is potentially a revolutionizing technology, but PV-CTA has already revolutionized the comprehensive diagnosis and treatment of peripheral vascular disease.
Scalable system delivers bang for investment buck
March 1st 2007This spring, the first sites in the world will begin using Philips Medical Systems' newly minted BrightView family of gamma cameras. The compact dual-head product, unveiled at the 2006 RSNA meeting, shines at the high end of the company's nuclear medicine portfolio in performance and versatility.
SPECT/CT boosts malignant lymph node detection in obese women
February 26th 2007Multiplanar SPECT/CT lymphoscintigraphy provides better sentinel node detection in patients diagnosed with breast cancer than planar imaging alone, according to a study in the February issue of the Journal of Nuclear Medicine. The technique shows particular promise for overweight patients.
Nuclear medicine outlook: The road ahead, a glance back
February 2nd 2007Expanded coverage for PET drove demand for procedures in 2006, helping push unit sales, which also benefited from local pressures on providers to keep up with the competition. Demand for upgrading the installed base to PET/CT from dedicated PET could bolster sales in the near term, just as the popularity of the modality continues to rise.
CAD firm prepares virtual colonoscopy launch in U.S.
February 1st 2007Italian computer-aided detection and imaging device company iM3D is slated to begin selling its CADColon iM3D system in this country this quarter. The company, which introduced itself to the U.S. radiology community in 2005 under the moniker iMED Medical Imaging Lab, is already selling CADColon in Europe and is awaiting approval from the FDA for marketing in the U.S. It plans to sell the product directly to customers but is also exploring relationships with imaging vendors interested in building its CAD algorithm into their workstations, said Alessandro Zuccato, head of sales.
MR colonography proves effective but unpleasant
February 1st 2007Although MR colonography is proving to be an effective method of colorectal screening, patients are no more likely to accept it than optical colonoscopy. In addition, limited bowel prep protocols for CT colonography are proving comparable to full cathartic prep.
Novel tracer for prostate cancer improves sensitivity
January 9th 2007Researchers at Emory University have demonstrated the uptake of a new radiotracer known as FACBC in both primary and metastatic prostate cancer on initial staging, as well as in recurrent cancer within the prostate bed, lymph nodes, and bone. They reported their findings in the January issue of the Journal of Nuclear Medicine.
Report from RSNA: Software boosts accuracy, reduces reading time for bone scans
January 2nd 2007Software designed by researchers at the University of Chicago helps detect interval changes in successive nuclear medicine bone scans and can reduce interpretation time by up to 32%, according to research presented in an educational exhibit at the RSNA meeting.
Coronary CTA lacks certainty as ischemia indicator
December 14th 2006Plaque buildup in the coronary arteries seen on 16- and 64-slice CT angiography does not always mean blood flow to the heart is restricted, according to research conducted at the Leiden University Medical Center in the Netherlands.
