New analyses of data from the Digital Mammographic Imaging Screening Trial show that digital mammography is superior only for pre- and perimenopausal women with dense breasts. Screen-film mammography may actually have an edge in older women with fatty breasts, according to a study presented at the RSNA meeting on Sunday.
Computed radiography arrived at the RSNA meeting Sunday ready for sale into the U.S. market as a mammography application. At the head of the pack was Fujifilm Medical Systems USA, the only vendor with FDA approval to sell CR for mammography. It received the agency green light in July.

There are two ways into the U.S. market for computed radiography for mammography. One path, successfully traversed by FujiFilm Medical Systems USA and now being trod by Kodak, is the FDA's premarket approval (PMA) process. But Konica Minolta is taking the road less traveled.

Kodak will showcase its computed radiography platform for mammography at the RSNA meeting, but it will have to do so as a work-in-progress, at least for customers in the U.S.

The imaging industry tallied another 34 FDA clearances in September, pushing the running count for the year to 261. Image management led all categories with 14 devices, followed by x-ray with 10, radiotherapy with four, ultrasound and CT each with two, and nuclear medicine with one. A surgical microscope accessory that is used to view intraoperative cerebral blood flow fits none of the traditional categories.

Elderly patients can undergo CT scanning of the pancreatobiliary region with only 90% or less of the contrast dose required in other patients without compromising the exam's quality.
I routinely read and enjoy the column by Dr. Bradley Tipler. But I was shocked and disappointed by the article in the June 2006 edition, ("Command of a tight ship stays out of reach," page 64). I work on the other side of the table.
For years, the world of breast imaging was quite simple. Screen-film mammography and ultrasound did not leap ahead, but they did a satisfactory job for most women. In the past few years, the armamentarium has exploded, with the introduction of modalities from MRI to vacuum biopsy. The management of breast disease has changed significantly.
The validity of population-based breast screening has once again been called into question by the world’s media. The negative headlines have, ironically, been triggered by a report that finds mammography screening saves lives. But it is the concurrent likelihood of overdiagnosis that has captured journalists’ attention.

Six years ago, Hologic looked like a company on the brink. Once the darling of the radiology industry with booming sales of bone densitometers, Hologic had sought to diversify, but its acquisitions were dragging the company down rather than lifting it up.
Buoyed by corporate acquisitions, Hologic will appear at the RSNA meeting with a 13,000-square-foot booth filled with works-in-progress for its mammography, CAD, and densitometry offerings, and enhanced by a first-time RSNA showing of an MRI system from Esaote and the Chicago debut of its newly acquired biopsy portfolio.

New audit data that will allow benchmarking in screening mammography for U.S. practices are set to be published in the October 2006 issue of Radiology.
Siemens Medical Solutions will launch its newly acquired MammoTest breast biopsy table at the RSNA meeting. The rights to the system were acquired by Siemens this summer from now-defunct Fischer Imaging in a deal brokered by the Federal Trade Commission. By late November, the company expects that its managers in every country will be versed in the prone stereotactic biopsy unit and ready to begin selling it globally, said Erica Rouleau, national sales director for women’s health at Siemens.
Computer-aided detection pioneer iCAD has upgraded its mammography CAD technology. The new product, Version 7.2, is now shipping with the company’s workstations SecondLook 300 and 700.
