Whole-body PET/CT and 3T MR perform equally well for lung cancer staging

July 31, 2008 Whole-body PET/CT and 3T MR perform equally well for lung cancer staging Don Rauf -------------------------------------------------------------------------------- No clear winner has emerged in a head-to-head comparison of whole-body FDG-PET/CT and whole-body 3T MRI for non-small cell lung cancer staging. Unenhanced PET/CT proved better for detecting metastatic lymph nodes and soft-tissue involvement, while MR was more sensitive to the presence of brain and liver metastases.… Continue

Nailing budgets and equipment in tough times

July 31, 2008 Nailing budgets and equipment in tough times Greg Freiherr -------------------------------------------------------------------------------- In uncertain economic times, there is always one sure thing. Prices are more likely to fall than rise. The bulls pull in their horns. Conservatism wins the day. And budgets usually—but not always— drop. Results from a survey by the medical information division of market research firm IMV, however, indicate that hospitals with fewer than 200… Continue

July 30, 2008 Proponents praise radiopharmaceutical reimbursement overhaul, with caveats H. A. Abella -------------------------------------------------------------------------------- Bexxar and Zevalin have become the poster children of inadequate reimbursement for radiopharmaceuticals.

MRI zeroes in on medial meniscal tears

July 29, 2008 MRI zeroes in on medial meniscal tears H. A. Abella -------------------------------------------------------------------------------- Studies from Korea and the U.S. show that MR imaging of the knee is a reliable and accurate test for the detection of specific subtypes of medial meniscal tears. Good understanding of MR-depicted anatomic features helps identify false-positive injuries of the menisci and avoid unnecessary surgeries. Radial tears are a common type of medial meniscal… Continue

Contrast-induced nephropathy fears ease

July 24, 2008 Contrast-induced nephropathy fears ease H. A. Abella -------------------------------------------------------------------------------- Ten years of clinical data from more than 30,000 patients suggest the estimated risk of sustaining renal damage from iodinated contrast media may have been blown out of proportion, according to Columbia University researchers. With proper scientific validation, contrast may be used even in patients with renal failure. Iodinated contrast agents used… Continue

MRI breast cancer staging proves benefits, shortcomings

July 23, 2008 MRI breast cancer staging proves benefits, shortcomings H. A. Abella -------------------------------------------------------------------------------- A metastudy by Australian and European researchers indicates that MR staging identifies additional disease in nearly one of five women previously diagnosed with breast cancer. It also suggests that women may undergo more extensive surgeries than originally planned because of false-positive MR findings. Evidence of MRI's value as an… Continue

GAO recommends preauthorization to slow explosive Medicare imaging growth

July 21, 2008 GAO recommends preauthorization to slow explosive Medicare imaging growth H. A. Abella -------------------------------------------------------------------------------- To the chagrin of imaging advocates, a Government Accountability Office study has found that preauthorization may be best way for Medicare to slow the rapid growth of outpatient MR, CT, and other high-tech imaging services. The June 2008 report confirmed findings of a 2005 Medicare Payment Advisory Commission study… Continue

Dawn of the Tera Era

July 17, 2008 Dawn of the Tera Era Greg Freiherr -------------------------------------------------------------------------------- It was only a few years after I had bought my first desktop computer in 1983 — a dual floppy with RAM so low I can no longer remember its size — that I watched my next- door neighbor install a memory card on the motherboard of his new PC. This top-of-the-line system had a hard drive with half a megabyte of storage. But the memory card that cost $750 held twice that… Continue

Palpation fails to reduce breast cancer mortality

July 16, 2008 Palpation fails to reduce breast cancer mortality H. A. Abella -------------------------------------------------------------------------------- Experience compiled from nearly half a million women suggests that breast self-examination has a negligible effect in reducing breast cancer-related deaths. The practice may even be putting an unnecessary strain on breast care resources, according to researchers in Denmark. Reputed medical institutions as well as patient advocacy groups… Continue
