Treatment guidelines from the FDA limit the ultrasonic ablation of uterine fibroids to 50% of the lesion mass, as seen and targeted with MRI, a limitation that has raised doubts in the medical community about whether the treatment can be effective. But Dr. Phyllis Gee, medical director of the North Texas Uterine Fibroid Institute in Plano, says physicians need not be concerned about the efficacy or long-lasting effect of this treatment.
Vendors are pouring money into R&D aimed at reducing radiation dose to patients when a simpler, more immediate answer might be at hand: positioning patients correctly before scanning.

Most of the potential associated with dual-beam CT scanning, a technology developed and being solely pioneered by Siemens Medical Solutions, has been in cardiology. The applicability of this technology to other disciplines is only beginning to be explored.
Fewer than one quarter of U.S. outpatient imaging centers surveyed by the marketing research firm IMV plan to purchase any type of high-end diagnostic imaging equipment between now and 2008, a draconian measure prompted by the implementation of the Deficit Reduction Act (DRA).

Whole-body MR imaging could complement-and, in some cases, even replace-traditional bone scanning techniques. Researchers across Europe have found that whole-body MRI has a significant impact on patient management compared with x-ray and nuclear medicine.
Multislice CT has steamed into our radiology departments like a nuclear-powered aircraft carrier. In its wake, an entire support industry has sprung up to help us quench our ever-increasing thirst for more and better slices.
A portable CT scanner built by NeuroLogica will be one door away from the dressing rooms of Oscar De La Hoya and Floyd Mayweather Jr. when the two middleweights duke it out May 5 at the MGM hotel and casino in Las Vegas. The dedicated head scanner will scan either or both, if physicians attending the boxers see any signs of neurological damage.
Nuclear medicine applications have boomed since PET studies secured reimbursement, and the use of hybrid modalities combining nuclear imaging with multislice CT scanning is growing. The potential for increasing radiation exposure for patients and medical workers requires beefing up radiation safety measures, according to two leading nuclear medicine experts who spoke at the 2007 National Council on Radiation Protection and Measurements meeting.

Quantitative Radiology is now part of AFP Imaging. Purchase of the Italian firm, which has installed about 500 conebeam CT scanners for dental applications over the past decade, is being framed as a coup by AFP chairman and cofounder David Vozick.
Physicians’ 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.
The Society of Nuclear Medicine’s campaign to guide advanced molecular imaging techniques into clinical practice has passed the halfway point in its goal of collecting $5 million to fund the effort.
N1177, 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.
Thailand, 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.

Several 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.
Toshiba and Siemens each rolled out a new CT at the European Congress of Radiology last week. Both launches are designed to target stragglers in the marketplace still operating outdated single-, dual- and quadslice systems.

Correct 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.

In the past, a person with chest pain entering the emergency department at the Hospital of the University of Pennsylvania could spend up to six hours there before being discharged.
We 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.
