Mammography

An add-on digital stereotaxy option for GE’s Senographe Essential lets users perform biopsies on its full-field digital mammography system, sparing institutions the expense of setting up a dedicated biopsy room, according to the company.

Computer-aided detection systems show high potential for detecting inconspicuous colonic polyps but provide little help in locating nonpolypoid colorectal lesions, according to research presented Wednesday at the RSNA meeting.

Automated breast ultrasound should not replace handheld ultrasound in a diagnostic breast center but rather should be used in conjunction with it or play a role in screening breast ultrasound, according to a study presented at the 2008 RSNA meeting.

While radiologists herald breast tomosynthesis as the hope for the future of breast imaging, several barriers hinder its widespread use. Its very ability to detect benign lesions dilutes the value of such detection, according to a keynote speech at the RSNA meeting.

Clinical trials in oncology demand standardized measurements of imaging scans to assess treatment response, but, unfortunately, the existing clinical workflow is not designed to produce these cohesive measurements on a routine basis. A group from Dana Farber Cancer Center has proposed using imaging analysts to deliver more consistent results.

Toshiba America Medical Systems has positioned its MicroPure ultrasound technology as a way to better characterize microcalcifications. The new technology, showcased at RSNA 2008 on Toshiba’s Aplio XG ultrasound scanner, improves the detection of small calcifications that otherwise may evade detection with ultrasound.

Extending its reach in applications for MR in women’s health, Toshiba unveiled at RSNA 2008 its Radiance Plus Breast Imaging Suite for use on the company’s two 1.5T scanners, the Vantage Atlas and Vantage Titan.

As the mammography community embraces digital mammography, newly converted sites must overcome the challenge of comparing new images with old. PACSGEAR introduced at RSNA 2008 its solution to the problem.

Digital mammography is more accurate than film for diagnosis of breast cancer in women with dense breasts, according to results from the Digital Mammographic Imaging Screening Trial presented at the RSNA meeting.

Sony has unveiled at RSNA 2008 a printer designed specifically for digital mammography.

In Pennsylvania, radiologists 65 and older read significantly more mammograms than any other group, according to an American College of Radiology patterns-of-care study.

Targeted radiation of breast cancer reduces treatment time from six and a half weeks to five days, while reducing pain and improving cosmetic outcome, according to a study presented at the RSNA meeting.

Emerging opportunities in breast imaging have inspired CoActiv to tailor its Exam-PACS to handle breast-specific gamma imaging files.

An aggressive, stealthy small breast cancer sub-type accounts for 10 percent of all breast cancers but half of all lesion-related deaths.

Preliminary results from American College of Radiology Imaging Network Trial 6657 show that MRI estimates residual breast cancer disease area better than clinical exams or mammography.

PET niche developer Naviscan arrived at the RSNA meeting with permission from the FDA to launch its Stereo Navigator, a biopsy guidance feature for its breast-specific PET scanner. Stereo Navigator can localize lesions as small as 2 mm. It uses a stereotactic frame fixed between the scanner’s paddles to guide a biopsy needle into the breast. Localization is verified using a PET-visible line source inserted into the needle track. This allows the user to confirm trajectory and position. The PET-guidance accessory is compatible with biopsy devices from Ethicon Endo-Surgery, Hologic, and SenoRx.

Enhancements in breast imaging mark the latest ultrasound upgrade from Philips Healthcare. Tissue aberration correction technology and algorithms built into the Vision 2009 upgrade for its iU22 radiological flagship are part of an integrated effort to better define tissue in fatty breasts, according to the company. An enabling technology is the Philips PureWave transducer and its coded beamformer, which have been present on earlier technologies.

Themes emerging from breast imaging abstracts at the upcoming RSNA include the increased use of breast MRI, full-field digital mammography versus film-screen mammography, and more.

Computer-aided detection significantly improves the sensitivity of pulmonary embolism imaging, according to a study that will be presented at the 2008 RSNA meeting. Other studies show that specially developed CAD schemes can detect flat lesions that are often missed in CT colonography.

Computer-aided detection is gradually gaining acceptance in radiology and has become a major research focus in the past few years. The development of CAD with multislice CT has reached the point where, together, they have the potential to offer new capabilities in the interpretation of emergency room scans.

It’s been a long time coming. Nearly a decade has passed since ATL took a serious run at advancing the medical art of breast cancer diagnosis. The company, long-since absorbed by Philips Healthcare, developed a novel algorithm designed for its Ultramark 9 HDI, later adapted for its HDI 3000 and 5000.

Full-field digital mammography was built on solid-state technology.The first such machines, introduced eight years ago,were based on flat-panel detectors, a tradition that continueduntil the commercial introduction of computed radiography afew years ago.
