Seno Medical ’s Imagio Combines Optoacoustics with Ultrasound to Diagnose Breast Cancer

At last week’s RSNA conference in Chicago, we got a chance to learn about Seno Medical Instruments, a San Antonio, Texas company, and its imaging technology that combines conventional ultrasound with a new modality called optoacoustic imaging. We spoke with Dr. Tom Stavros, Medical Director at Seno. The company’s Imagio system relies on a duplex probe that looks and acts like a regular ultrasound transducer, but that also emits laser light to simultaneously work as an optoacoustic imaging device. In optoacoustics, laser light is used to add energy to tissue, which is then released in the form of ultrasound waves. These waves can be detected, but unlike conventional ultrasound, they contain information about blood and its oxygenation. Ultrasound is pretty good at seeing the structures of tissues, and in this device, optoacoustics provides the functional view of blood oxygenation and improves the contrast, which can make it critically important for spotting tumors, as tumors eat up a lot more oxygen than nearby tissues. The Imagio system is intended for breast cancer diagnostics rather than screening, and patients are expected to have been screened using ultrasound before being imaged by Seno’s system. Roughly 80% of breast biopsies turn out negative these days, a disturbingly high number, so anything to improve this would be highly beneficial for reducing costs, improving the emotional well being of patients, and getting the right people quic...

Authors: Agarwal R, Diaz O, Lladó X, Gubern-Mérida A, Vilanova JC, Martí R Abstract Mammography is the gold standard screening technique in breast cancer, but it has some limitations for women with dense breasts. In such cases, sonography is usually recommended as an additional imaging technique. A traditional sonogram produces a two-dimensional (2D) visualization of the breast and is highly operator dependent. Automated breast ultrasound (ABUS) has also been proposed to produce a full 3D scan of the breast automatically with reduced operator dependency, facilitating double reading and comparis...

Mobile health devices aim to ease healthcare, and perhaps even expand it. Clarius Mobile Health, for instance, set out to “enable more clinicians to use ultrasound to improve patient care,” the company reports on its Web site. The company then went on to develop wireless Clarius Ultrasound Scanners for scanning various parts of the body and for guiding short procedures, describing the devices as  "almost as easy to use as the camera on your smart phone." To date this year, the company has delivered more than 1600 scanners, shared Clarius CEO Laurent Pelissier in a news release. Clarius ...

Hologic (NSDQ:HOLX) said recently that it won FDA 510(k) clearance for its Quantra 2.2 breast density assessment software and that it inked a development and distribution deal with Clarius Mobile Health for its wireless, handheld ultrasound scanner. The Marlborough, Mass.-based company said the Quantra 2.2 software uses a proprietary algorithm to analyze mammography images for the distribution and texture of breast tissue to produce patient-specific breast density assessments. “As the global leader in breast cancer screening technology, we relentlessly pursue the development of clinically superior products that ...

A 68-year-old woman with a recent history of blurring in the left eye had undergone mastectomy for breast cancer twenty years ago. A series of bone metastases started five years after her diagnosis. Examination of the optic nerve head of the left eye revealed an isolated epipapillary mass. Indocyanine green angiography displayed vessels within the mass, and fluorescein angiography demonstrated hyperfluorescence of the mass from vascular leakage plus lobular spots of blocked fluorescence. B-scan ultrasound revealed a hyperechoic elevated nodular mass on the optic disc.
