November 18, 2015 — At this year's Radiological Society of North America (RSNA) annual meeting, Gamma Medica Inc. invites congress attendees to experience LumaGEM, the latest in molecular breast imaging (MBI). The LumaGEM MBI system features dual-head Digital Direct Conversion Gamma Imaging (DDCGI) technology that identifies tumors as small as 5 mm in dense breast tissue where mammography findings are inconclusive or even negative.

The growing awareness of the limitations of mammography screening for women with dense breast tissue and the necessity for an effective adjunct screening technology led to the creation of LumaGEM MBI. Unlike mammography, tomosynthesis, ultrasound and magnetic resonance imaging (MRI), all of which are anatomical imaging tests, MBI is a functional imaging modality that highlights metabolic activity in the breast and detects tumors not visible on a mammogram due to tissue density.

A recent study conducted by Mayo Clinic, and published in two articles in the American Journal of Roentgenology (AJR) in 2015, determined that the addition of MBI to an annual mammogram screening demonstrated a near 400 percent increase in invasive breast cancer detection rates, 50 percent reduction in biopsies and a subsequent 15 percent lower cost per cancer detected than screening with mammography alone. With over 90 percent sensitivity and specificity, LumaGEM MBI has been shown to significantly improve cancer detection in women with dense breast tissue and complicated mammograms with fewer false positives relative to anatomical imaging technologies.

The LumaGEM MBI system is U.S. Food and Drug Administration (FDA)-approved and received its CE Mark allowing for the sale and distribution within the European Economic Area (EEA).

There were several new developments in digital radiography (DR) technology at the 2019 Radiological Society of North America (RSNA) annual meeting. These trends included integration of artificial intelligence (AI) auto detection technologies, more durable glassless detector plates, and technologies to pull more diagnostic data out of X-ray imaging. Some vendors also have redesigned their DR systems to make them more user-friendly and ergonomic.

In vivo imaging is performed in conical scanning geometry by controlling the rotation and translation stages. The sensing part of the transducer array and the tumour are submerged in water to provide acoustic coupling. b Maximum intensity projections of the optoacoustic reconstruction of a phantom of polyethylene microspheres (diameter, 20 μm) dispersed in agar. The inset shows a zoomed-in view of the region boxed with a yellow dashed line. In addition, the yellow boxes are signal profiles along the xy and z axes across the microsphere centre, as well as the corresponding full width at half-maximum values. c Normalized absorption spectra of Hb, HbO2 and gold nanoparticles (AuNPs). The spectrum for the AuNPs was obtained using a USB4000 spectrometer (Ocean Optics, Dunedin, FL, USA), while the spectra for Hb and HbO2 were taken from http://omlc.org/spectra/haemoglobin/index.html. The vertical dashed lines indicate the five wavelengths used to stimulate the three absorbers: 710, 750, 780, 810 and 850 nm. Optoacoustic signals were filtered into a low-frequency band (red) and high-frequency band (green), which were used to reconstruct separate images.

The Breast Imaging and Reporting System (BI-RADS) was established by the American College of Radiology to help classify findings on mammography. Findings are classified based on the risk of breast cancer, with a BI-RADS 2 lesion being benign, or not cancerous, and BI-RADS 6 representing a lesion that is biopsy-proven to be malignant.
