GE Healthcare CardIQ Xpress Elite Aids Diagnosis

CT rest perfusion image obtained with CardIQ Xpress showing region of interest as compared to MR and rest MIBI with delayed contrast enhancement.

CardIQ Xpress Elite computed tomography angiography analysis software allows more speed and information so users can make an accurate, confident diagnosis. With the new AutoLaunch capability, images are ready to read and review in real time, improving workflow by up to 40 percent.

When utilizing the coronary vessel analysis tool, the vessels are tracked with greater than 93 percent accuracy. The systems relative perfusion capabilities provide color-coding of the myocardial tissues to display the hypo/hyper-dense area at rest.

(a) Cardiac MRI perfusion shows perfusion deficit of anterior/anterolateral wall attributed to left anterior descending artery/left circumflex artery (*). (b) CT coronary angiography. (c) Coronary angiography, left anterior oblique projection with caudal angulation. (d) Three-dimensional image fusion helped refine diagnosis: perfusion deficits (*) were most likely caused by narrow first diagonal branch and its first, stented side branch.

Carestream’s X-ray digital tomosynthesis functionality creates three-dimensional datasets from digital radiography (DR) that can be scrolled through similar to computed tomography (CT) imaging. It received 510(k) clearance from the U.S. Food and Drug Administration (FDA) in January 2020. Digital tomosynthesis uses a single sweep of X-ray exposures and streamlines operator workflow by separating the process of DT exposure acquisition from image volume formation.
