ViosWorks enables large image datasets of the whole chest to be post processed and evaluated in real-time via cloud technology.

December 15, 2015 — At RSNA 2015, GE Healthcare showcased Viosworks, a new, advanced application to greatly simplify cardiac magnetic resonance imaging (MRI) exams. GE hopes the software will enable cardiac MRI to gain ground in the U.S. market, where it curly only makes up about 1 percent of MRI exams due to the time and complexity.

ViosWorks is designed to help solve several cardiac MR challenges at once. It delivers a three-dimensional spatial and velocity-encoded dataset at every time point during the cardiac cycle, yielding high resolution, time-resolved images of the beating heart and a measure of the speed and direction of blood flow at each location. ViosWorks captures seven dimensions of data (three in space, one in time, three in velocity direction).

It uses a free-breathing scan that can be acquired in less than 10 minutes. A conventional cardiac MRI takes about 70 minutes. ViosWorks can simultaneously provide key elements of a cardiac MR exam: anatomy, function and flow. This provides four advantages.

• The exam is simplified for the patient by using a single 3D free-breathing scan.
• The error-prone and time-consuming aspect of slice positioning is removed.
• Co-registered anatomic images provide the ability to assess cardiac functioning 3D and contextualize
flow abnormalities, and as a result, the cardiac exam can be reduced from over 60 minutes to
approximately 10 minutes or less.
• New algorithms allow large datasets unimaginable before to be evaluated in real-time via the cloud
based Arterys software. Arterys visualization is designed to significantly reduce the amount of time spent on data processing and bring new visualization routines to life.

The software is designed for use on the Signa Pioneer 3.0T, Signa Explorer and Signa Creator 1.5T MRI scanners.

(A) Schematic depiction of the automated process for assessing fat, muscle, liver, aortic calcification, and bone from original abdominal CT scan data. (B) Case example in an asymptomatic 52-year-old man undergoing CT for colorectal cancer screening. At the time of CT screening, he had a body-mass index of 27·3 and Framingham risk score of 5% (low risk). However, several CT-based metabolic markers were indicative of underlying disease. Multivariate Cox model prediction based on these three CT-based results put the risk of cardiovascular event at 19% within 2 years, at 40% within 5 years, and at 67% within 10 years, and the risk of death at 4% within 2 years, 11% within 5 years, and 27% within 10 years. At longitudinal clinical follow-up, the patient suffered an acute myocardial infarction 3 years after this initial CT and died 12 years after CT at the age of 64 years. (C) Contrast-enhanced CT performed 7 months before death for minor trauma was interpreted as negative but does show significant progression of vascular calcification, visceral fat, and hepatic steatosis.
