Imagio is a multi-modality device, comprised of opto-acoustic (OA) imaging co-registered with diagnostic grey-scale (B mode) ultrasound, that has been designed to concurrently collect OA images in conjunction with diagnostic grey-scale (B-mode) ultrasound.

Imagio is expected to identify two functional hallmarks of a potential malignancy: the presence of abnormal blood vessels (angiogenesis); and the relative reduction in oxygen content of hemoglobin. The technology is non-invasive and does not require any contrast agent or radio-isotope, which is required for other modalities such as MRI or PET.

This is a prospective, single arm, controlled, multi-center, observational study that will compare Imagio versus conventional diagnostic ultrasound (CDU) for the visualization of suspicious masses.

Primary Outcome Measures:
  • The primary outcome measure is the test of sensitivity and specificity of Imagio vs. standard of care ultrasound in breast lesions based on the probability of malignancy (POM). [ Time Frame: The primary endpoint is evaluated prior to biopsy for subjects with a positive-diagnostic ultrasound, and is evaluated at 12-months for subjects with a negative-diagnostic ultrasound. ] [ Designated as safety issue: No ]

Estimated Enrollment: 2000
Study Start Date: July 2013
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
