Image-guided percutaneous biopsy is safe and accurate, and it holds potential for eliminating needless nephrectomies, according to two studies presented at the American Roentgen Ray Society meeting in Vancouver.

GE Healthcare introduced today a miniaturized version of its 4D ultrasound system for women’s health and prenatal applications. The Voluson i is about the size of a laptop yet produces real-time volumetric images and displays them on a screen as big as the company’s cart-based 4D Voluson 730.

A California lawmaker has announced a bill that would restrict sales of ultrasound machines to medical professionals. The move follows public safety concerns raised by actor Tom Cruise’s November 2005 purchase of sophisticated equipment to perform ultrasound exams on his pregnant fiancée.

Percutaneous cryoablation of renal tumors is 100% effective, according to a report presented Monday at the American Roentgen Ray Society meeting.

For years, interventional radiologists have seen vascular disease management slip through their fingers and into the hands of cardiologists and surgeons. A new ultrasound-based technique, however, may help them reclaim lost turf.

The industry rebounded in March from a sluggish start to the year as the FDA cleared 34 devices under 510(k) review, nearly matching the number cleared in the previous two months together. March brought the total to 72 radiological devices cleared so far in 2006, making up for the slow start and putting vendors on track with previous years.

Researchers from Seoul National University Medical Center have found that breast cancers detected by ultrasound only are not very sensitive to computer-aided detection.

Renal cell cancer is the most frequently encountered malignant tumor in the kidney. Over 30,000 new cases are diagnosed annually in the U.S. Many cases are now detected incidentally, as a result of the widespread use of multislice CT. MSCT usage is also redefining diagnostic workup of renal lesions and facilitating renal cell cancer staging.

Ultrasound provides a safe and accurate method of detecting breast cancer and assessing response to chemotherapy in pregnant women, according to a study in the April issue of Radiology.

Duke University engineers have developed a miniature ultrasound transducer capable of generating data for high-quality real-time 3D images, transducers so small they fit in a laparoscope, intracardiac catheter, or transesophageal probe. So far the images have been only of dogs, but Duke’s lead engineer on the project believes the step to human application is a small one.

MR-guided focused ultrasound surgery is a safe, effective treatment for uterine fibroids. The number and size of fibroids do not affect outcome, according to a pair of studies presented at the 2005 RSNA meeting.

Transvaginal ultrasound and serum CA 125 blood tests, used individually or in combination, can detect ovarian cancer early, according to preliminary results from a study conducted by the National Cancer Institute. But both tests produce too many false positives, prompting needless surgeries.

Patients often ask sonographer Cynthia Rapp just what it takes to perform ultrasound. Her frank response about the necessary qualifications sometimes comes as a surprise.

Data from around the world released at the 2005 RSNA meeting suggest that contrast-enhanced ultrasound use in molecular imaging will expand. Applications include the evaluation of tumor angiogenesis and lymph node metastases at nearly cellular levels as well as guidance, delivery, and assessment of gene therapy.
