Mammography

Digital tomosynthesis shows promise for improved lung nodule detection compared with chest radiography. It may also improve performance of CAD algorithms for lung nodule detection by eliminating structure overlap that causes many false positives, according to a study presented at the 2005 RSNA meeting.

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

Minimally invasive CT colonography has been embraced by radiologists and patients alike. As the technique evolves, its use is shifting from specialized academic centers to community hospitals and private practices. That transition is focusing increased attention on reimbursement, clinical efficacy, and interpretation issues. Computer-aided detection for CTC could affect all three.

Less than a week after going public with its intent to acquire Suros Surgical, Hologic announced the signing of a definitive agreement to acquire R2 Technology, the acknowledged pioneer of computer-aided detection. The stock swap is valued at $220 million. With the Suros deal (valued at $240 million) already on the table, Hologic now has about a half-billion dollars in transactions in the works.

Women’s health imaging specialist Hologic has signed a definitive agreement to acquire Suros Surgical Systems, a maker of breast biopsy equipment. The deal, valued at more than $240 million, could make the Indianapolis company a wholly owned subsidiary of Hologic by the end of the second quarter, pending due diligence and final approval by Suros’ investors and regulatory clearances.

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

The merits of screening mammography have again become a subject of debate following new research suggesting that breast cancer surgery speeds up disease progression in young women. The study's authors recommend that breast screening consent forms include the risk of accelerated tumor growth and early relapse.

A relatively new small field-of-view gamma camera has proved promising for two of the most hard-to-detect breast cancers: ductal carcinoma in situ and invasive lobular carcinoma.

Capitalizing on the momentum generated by advances in human genomic research, the National Cancer Institute has launched an initiative to identify genetic alterations that make people susceptible to prostate and breast cancer.

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.

Options for image-guided procedures in the breast have expanded considerably over the past 20 years. A variety of modalities are now being used to perform diagnostic, localization, and therapeutic interventional procedures for breast disease.

Acquiring information about mammography procedures is one thing. Using that information in a report and follow-up is something else. That's where programs like MagView come in. The mammography information system can be configured with integrated scheduling, billing, radiology reporting, transcription, patient tracking, management reporting, and equipment quality control.

Released in late January, Fusion Matrix PACS version 2.1 introduces reading enhancements, including the ability to query and retrieve studies from third-party DICOM sources, reserve studies, and mark studies as preliminary. Other new tools include triangulation, which lets the user define a target point on an image to view the corresponding anatomic position in other series.

Upgrades and enhancements for digital mammography systems are good news for women’s health practitioners who have already invested in the next stage of mammography. But those still contemplating the move to digital technology are beginning to consider alternatives.

Computer-aided detection has carved out a role in the last few years as a tool for flagging subtle lesions that have the characteristics of cancer. As demonstrated by new products at the 2005 RSNA meeting, CAD is expanding its scope to find abnormalities or alterations in anatomy that may call for a change in the management of patients.

Prospective buyers of digital mammography equipment got a warning at the 2005 RSNA meeting: Watch out when comparing images from equipment made by different vendors.

All year long, we at Diagnostic Imaging write about important radiology issues. You might think that by the time the RSNA meeting rolls around, we would have covered just about everything. Well, in a sense, we have. But the reality is that the "big show" never ceases to amaze us. Each year, forecasted trends don't materialize, surprise trends sneak up, and the usual number of boom and bust predictions either boom... or bust.

The study's authors recommend that breast screening consent forms include the risk of accelerated tumor growth and early relapse.

The clinical trial numbers may be small, but the ambitions of one new technology-breast tomosynthesis-were nevertheless larger than life at the RSNA meeting. While many of the breast imaging papers showcased refinements to relatively new techniques, breast tomosynthesis stood out by promising a revolution.

Interest in digital mammography was strong on the 2005 RSNA exhibit floor, driven at least in part by positive results from the Digital Mammographic Imaging Screening Trial, whose results were announced 10 weeks prior to the start of the meeting. A few doors down from the prospective buyers crowding exhibitor booths, however, early adopters of the equipment were sounding an alarm.

As computer-aided detection continues to make inroads into virtual colonoscopy territory, studies presented at the 2005 RSNA meeting highlighted its potential for spotting polyps.

R2 Technology is leveraging knowledge gained in developing computer-aided detection to make products easier and more efficient to use.

Digital breast tomosynthesis promises to dramatically reduce the rate of false-positive mammograms, potentially sparing women from unnecessary follow-up tests and biopsies, according to a study presented at the RSNA meeting.

R2 Technology is making machines smarter and, in the process, easing the transition to digital mammography.
