Cardiac Imaging

The cardiac imaging channel includes the modalities of computed tomography (CT), cardiac ultrasound (echocardiography), magnetic resonance imaging (MRI), nuclear imaging (PET and SPECT), and angiography. 

GE Healthcare partnered with the AI developer Dia to provide an artificial intelligence algorithm to auto contour and calculate cardiac ejection fraction (EF). The app is now available on the GE Vscan pocket, point-of-care ultrasound (POCUS) system, as seen here displayed at RSNA 2019. Watch a VIDEO demo from RSNA.

The researchers used high resolution cross-sectional imaging with CT or MRI to assess 225 men with abdominal aortic aneurysm. Follow-up lasted, on average, more than three years.  Slightly more than half of patients had an intraluminal thrombus. The aneurysms of those with intraluminal thrombus were larger at baseline and grew by a rate of 2 mm per year, twice as fast as the 1 mm per year growth rate in people without intraluminal thrombus.

This is an example of artificial intelligence automation for cardiac MRI using an AI app from TeraRecon's Envoy AI marketplace. The GE MRI image has bee countoured, anatomy labeled and all quantification automated by the AI, greatly reducing post-processing time. See this and other new AI imaging technologies from the 2019 RSNA meeting.

Figure 1 from the new ASE ischemia cardiac ultrasound imaging guidelines, showing a side-by-side views of apical 4- and 2-chamber images, at rest and immediately post-exercise. In the four-chamber view, the left ventricle is shown on the left-hand side of the screen. With exercise, the echocardiogram shows the LV cavity dilates (right quadrants) and there are regional wall motion abnormalities in the LAD territory.
