Ultrasound

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.

Results from a new study confirm that ultrasound reliably predicts success and failure of single-dose methotrexate treatment of ectopic pregnancy. On the basis of their findings, Boston Medical Center researchers say a change is needed in clinical protocols.

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.

A radiologist was given a two-year prison term for using ultrasound to determine the sex of a fetus, according to a March 29 Associated Press report.

Findings of a Stanford University survey suggest teaching hospitals should reinforce training for radiology residents if they are to perform after-hours ultrasound scanning. Using residents to make up for the shortage of qualified sonographers could undermine medical education and compromise patient care. Data were published in the February issue of Academic Radiology.

Toshiba launches dual-panel system at ACC showAn angiography system that supports both cardiac and peripheral applications debuted March 11 in the Toshiba America Medical Systems booth during the American College of Cardiology meeting. Infinix DP-i/FD2, which incorporates two flat-panel detectors, meets ACC guidelines for both types of applications, according to the company. The system features an 8 x 8-inch floor-mounted cardiac C-arm and a 12 x 16-inch ceiling-mounted C-arm. The design allows coronary and vascular studies on the same table, increasing overall patient comfort and saving time that would otherwise be lost moving the patient to a second system.

A decade has passed since luminaries began generating promising clinical results using ultrasound elastography, which measures the elastic properties of tissue. Two years ago, Hitachi Medical began commercializing this technology. Now that company’s experience with its EUB Logos 8500 and pioneering work with a modified Siemens Allegra suggest that efforts to push elastography forward could soon begin paying dividends for vendors, customers, and patients.

The FDA was good to the radiology industry in 2005. For the third time in as many years -- and the fourth in the last five -- the regulatory agency cleared more than 300 radiological products. The last quarter could have been better, however.

Using intravascular ultrasound, researchers have found that intensive cholesterol lowering with a statin drug can regress the buildup of plaque in the coronary arteries, according to a study presented at the annual meeting of the American College of Cardiology in Atlanta.

An unusual eulogy by a urologist sparked peals of laughter from radiologists during a prostate cancer imaging session at the European Congress of Radiology. The topic focused on a physical test that men have come to know, if not exactly love.

Contrast-enhanced ultrasound (CEUS) is far superior to conventional B-mode ultrasound studies and roughly as good as 64-slice CT for detection of liver metastases, according to a study from Italy presented at the European Congress of Radiology on Saturday.

Modern imaging has a ways to go before it can replace breast biopsy. A study conducted by the Agency for Healthcare Research and Quality indicates that currently available noninvasive imaging methods fall short of the accuracy needed to determine conclusively whether a lesion is cancerous.

Use of ultrasound elastography, which measures the elastic properties of tissues, may help reduce the rate of biopsies in benign lesions by half, according to new results from a British breast cancer screening program.

Optical coherence tomography, a light-based imaging strategy, was found to compare favorably with intravascular ultrasound and to nearly match histopathology in determining the structure of atherosclerotic plaques in a study presented Saturday.

Contrast-enhanced ultrasound (CEUS) is far superior to conventional B-mode ultrasound studies and roughly as good as 64-slice CT for detection of liver metastases, according to a study from Italy presented at the ECR on Saturday.

A small study from a breast cancer surveillance program of high-risk women found that annual MR imaging did not detect additional cancers beyond conventional screening with both mammography and clinical physical examination.

CT and MR angiography both provided more clinically useful information than duplex ultrasound in screening peripheral vascular disease. But when costs are factored in, CT emerged as the clear leader, according to a four-hospital study conducted in the Netherlands and described Saturday.

MR offers decided advantages as a tool for image guidance in radiofrequency ablation of liver tumors, but it also presents significant problems that must be overcome before its use becomes widespread, according to a pair of presentations March 5 at the European Congress of Radiology.

Enthusiasm about ultrasound as a complementary tool for screening women with dense breasts may be exaggerated or even unfounded, according to an Italian radiologist speaking Friday morning at the European Congress of Radiology in Vienna.
