Mammography

Full-field digital mammography is comparable to screen-film in detecting breast cancer, according to results of a randomized trial in Norway involving nearly 25,000 women.

Combining computer-aided detection with screening mammography increases marginal costs per year of life saved by 19%. This is well within the cost-effectiveness range of other medical procedures, according to a study presented Monday.

An investigational device shown as a work-in-progress at the RSNA meeting promises to improve the detection of breast cancer by keying off the process of angiogenesis, which can transform an innocuous tumor into a lethal one by triggering the growth of new blood vessels to feed the cancer.

Preliminary findings from a national trial of ultrasound as a screening tool in patients at high risk for breast cancer shed light on key variables that influence radiologist interpretive performance.

Hologic, which in recent years has made women’s health its principal focus, is showing its full-field digital breast tomosynthesis system as a work-in-progress for the second consecutive RSNA meeting. Despite growing interest in this technology, the company expects to present it as a work-in-progress again next year.

The Access Breast Coil appearing for the first time at the RSNA meeting has a multichannel phased-array architecture to enhance image quality of the breast, axillary tissue, and chest wall. The investigational device, which is being shown at the Confirma booth, has multiple receivers to power the phased-array coils, which may reduce MR imaging time, as well as a large field-of-view. It can support unilateral and bilateral imaging.

PET pioneer acquires micro-CT firm CTI Molecular Imaging plans to acquire ImTek, a provider of micro-CT systems for imaging laboratory animals used in medical research. The $3.75 million cash deal is expected to close by the end of November. Financial performance and milestone achievements hold the potential for future incentive payments. The acquisition of ImTek, which designs and manufactures the MicroCAT scanners, would complement CTI Concorde, a business unit of CTI Molecular Imaging dedicated to the manufacture of micro-PET scanners.

Full-field digital mammography and advanced digital applications will dominate this year’s mammography offerings on the RSNA exhibit floor.

Digital mammography is inevitable. People may argue over the details, but everyone accepts the fact that screen-film mammography-radiology's last major analog holdout-cannot stand forever.

Hormone replacement therapy, previous breast surgery, and a low body mass index may reduce the accuracy of screening mammography, according to a study in the August issue of the British Medical Journal.

Philips cuts deal with healthcare enterpriseMarietta Memorial Hospital and Philips have struck a multiyear strategic agreement to bring advanced medical technology, clinical support, and staff education to the southeastern region of Ohio. Marietta and Philips have worked together for more than 10 years to outfit Marietta’s Cancer Center with digital x-ray and CT simulator systems.

Just like double-checking a grocery receipt to make sure you haven’t been overcharged, researchers suggest attention be paid to x-ray stereotactic biopsy cores to ensure they contain previously targeted calcifications. Cores obtained without such calcifications have a higher chance of missing malignant lesions.

Computed radiography for mammography cannot yet be sold in the U.S., but mammographers elsewhere in the world have been able to buy it from Agfa Healthcare. Many of those who bought this technology, called the Embrace CR (1A), probably wish they hadn’t.

Mammo display receives clearance for marketThe U.S. market will soon have a new flat-panel display for mammography. Barco has received FDA clearance to begin marketing its Coronis 5MP Mammo product. The clearance comes just weeks after the FDA passed Barco’s CRT-based MGD 521M mammography display.

The FDA issued on July 13 a 510(k) clearance to Totoku Electric for its ME511L, a 5-megapixel monochrome digital mammography LCD monitor. SCAN incorrectly stated that the clearance was obtained by U.S. Electronics, a distributor of Totoku monitors in the
