Niche MRI vendor Advanced MammographySystems will debut its long-awaited MR mammography scanner atthe RSNA show. The company, which is a subsidiary of fast MRIdeveloper Advanced NMR Systems, will also hold a special briefingon Sunday, Nov. 27, to unveil the unit.
AMS has yet not released the name of the system, but the scannerfeatures a 0.5-tesla superconducting magnet similar in appearanceto a standard MRI scanner, according to Robert Kwolyk, vice presidentof sales and marketing for the Wilmington, MA, company. Thereare significant differences, however: Patients will enter themagnet bore feet first and in a prone position, with the breastshanging through holes in the patient table. The scanner's specialradio-frequency coils are embedded within the table, Kwolyk said.
The scanner will feature sequences optimized for breast imaging,according to Kwolyk. The company is reluctant to discuss whetherthe scanner will be used for screening, lesion differentiationor both, preferring instead to leave the development of clinicalapplications up to physicians. Use of the scanner for imagingleaks in silicone breast implants is one application whose utilityis already evident, however.
The scanner has been designed to support an integrated breastbiopsy capability that may be developed in the future, accordingto Kwolyk. It may also be possible to integrate breast therapywith the system.
Advanced Mammography Systems has designed the system for cost-effectivescanning, Kwolyk said. The price of the system will probably beunder $500,000 and the scanner can complete an examination in15 minutes. The system sites in less than 300 square feet. Thecompany is in the process of filing a 510(k) application for theproduct.
Seven Takeaways from Meta-Analysis of PSMA Radiotracers for Prostate Cancer Imaging
December 1st 2023In a newly published meta-analysis of 24 studies, researchers noted that the PSMA PET radiotracer 18F PSMA-1007 may provide more benefit than 68Ga Ga-PSMA-11 for primary staging of patients with prostate cancer and detection of local lesion recurrence, but also has drawbacks with higher liver uptake and multiple reports of false positive bone lesions.
Study: Regular Mammography Screening Reduces Breast Cancer Mortality Risk by More than 70 Percent
November 30th 2023Consistent adherence to the five most recent mammography screenings prior to a breast cancer diagnosis reduced breast cancer death risk by 72 percent in comparison to women who did not have the mammography screening, according to new research findings presented at the annual Radiological Society of North America (RSNA) conference.
