Effective breast CAD still harbors a few workflow caveats
Computer-aided detection (CAD) has become a valued ally in breast cancer screening, boosting overall detection rates and detecting cancers earlier. But CAD has its caveats. Even in mammography, CAD won’t turn a poorly performing radiologist into a breast cancer specialist. And the technology may not be cost-effective for every breast center.

IHE pursues user adoption, product development, IT expansion
The quest involved in Integrating the Healthcare Enterprise (IHE) is not so different from the daunting mission that consumes the characters in J.R.R. Tolkien’s Lord of the Rings trilogy. Both involve a long journey by a hardy band of individuals, tasked with the near-impossible. The partnerships seem unlikely, and yet, in both cases, the teams ultimately prevail. For the five-year IHE project, what would seem to be journey's end is turning out to be another new beginning.

Pinhole technique abets dedicated breast SPECT imaging
Still in its early stages, a new breast imaging technique that pairs SPECT with pinhole collimation shows promise in detecting small lesions with high contrast and signal-to-noise ratios, according to investigators from Duke University Medical Center in Durham, NC.

Key variables impact accuracy of digital mammography
Slight differences in breast cancer detection rates between full-field digital mammography (FFDM) and film-screen might boil down to two simple questions: How is the patient being positioned and who is interpreting the images? Dr. R. James Brenner, medical director of breast imaging at Eisenberg Keefer Breast Center in Santa Monica, CA, tackles these questions and more.

Strict attention to detail enhances sensitivity of breast US
By applying a strict algorithm for differentiating benign from malignant lesions, sonographers can make more specific diagnoses, prevent biopsy of benign lesions, and find palpable malignant tumors missed by mammography, according to Dr. A. Thomas Stavros, chief of ultrasound at Radiology Imaging Associates in Greenwood Village, CO.

Radiologists say training, not tests, will hone mammography skills
Better education and training, not regulation, are needed to improve mammography skills, according to radiologists reacting to a U.S. proposal to mandate periodic exams as a way of improving breast cancer screening.

Gastric bypass battles bulge, but patients pose imaging challenge
As obesity becomes a national health issue in the U.S., a growing number of Americans are turning to surgery as a way to battle their bulge. But gastric bypass, one of the fastest-growing surgeries at U.S. hospitals today, poses multiple challenges for radiologists and technologists performing postprocedural imaging to detect complications.

Tips and techniques make MRI feasible for breast centers
Breast MRI is a valuable problem-solving tool in breast imaging, but even this highly sensitive technique can be humbled. Exam timing, indications, and technique are critical to success, according to Dr. Bruce Porter, medical director of First Hill Diagnostic Imaging in Seattle.

New adjunctive breast techniques improve positive biopsy rates
LAS VEGAS - Nearly 80% of the 1.3 million breast biopsies performed in the U.S. each year to evaluate suspicious mammographic findings are benign, the FDA reports. But new adjunctive technologies in development could put a serious dent in that percentage, according to a presentation Monday at the National Consortium of Breast Centers.

Ultrasound nonmass breast lesion features may signal malignancy
By Amerigo Allegretto
Some nonmass breast lesion characteristics on ultrasound exams can be considered suspicious for malignancy at screening ultrasound.
November 5, 2024
Images depict a 43-year-old woman with a malignant non-mass lesion that was diagnosed as microinvasive ductal carcinoma. (A) Transverse and (B) longitudinal ultrasound images show a hypoechoic non-mass lesion (solid arrows) with segmental distribution in the left breast. The lesion has associated calcifications (dashed arrows in A). (C) Longitudinal color Doppler ultrasound image shows high vascularity. (D) Magnified image in the mediolateral oblique view from screening mammography shows grouped calcifications (arrows), which are considered a mammographic correlate of the ultrasound-detected non-mass lesion (A radiopaque marker attached to the skin is visible in the image because the mammographic exam was performed after screening breast ultrasound). Ultrasound-guided core needle biopsy and pathologic examination revealed ductal carcinoma in situ, but the lesion was upgraded to microinvasive ductal carcinoma at subsequent surgery (2.5-cm ductal carcinoma in situ, histologic grade II, estrogen receptor-positive, progesterone receptor-positive, human epidermal growth factor receptor type 2-negative).
