CAAS MR Software Allows for Fast Functional Analysis for Cardiac MRI

Pie Medical Imaging’s FDA-cleared cardiac magnetic resonance quantitative analysis software, CAAS MR Magnetic Resonance Ventricular analysis software reportedly enables cardiologists and radiologists to perform easy and fast functional analysis on cine-magnetic resonance images for cardiac MRI studies. The quantitative analysis package provides (automatic) segmentation of the endo- and epicardial left ventricular heart wall on short- and/or long axis images.

Delayed enhancement studies can easily be quantified using the viability analysis module, while CAAS MR perfusion analysis module enables assessment of the local deterioration of myocardial blood flow, features that are only marked for investigational use in the U.S. at this time.

In the latest release of CAAS MR, the flexibility of image import is increased by allowing a wider spectrum of image acquisitions. Enhancement is made in calculation of volumes and ejection fraction using only long axis images in the functional analysis module. The analysis of first past perfusion is improved by offering more flexibility for upslope calculation as well as improvement of automatic breathing motion correction.
