Siemens Sola Cardiac Edition

August 24, 2018 -- At the annual meeting of the European Society of Cardiology (ESC) that starts this weekend in Munich, Siemens Healthineers plans to unveil a cardiovascular MRI scanner designed to offer special features for heart assessment, including technology that allows for free-breathing exams.

"Because of the difficulties of MRI, cardiologists often opt for multimodality exams, such as ultrasound, CT, and SPECT, when in fact all quantitative information about a patient's condition can be gained from one modality: MRI. We developed our cardiovascular edition with these fragile patients in mind," he noted.

"The Dot Engine, based on machine learning, includes automated techniques such as angulation to make cardiac MR easier. Previously, these techniques were lengthy, but the software takes a lot of the time and frustration away from the process," Fischer noted. "Cardiologists can set up protocols ahead of time to run through processes automated, which is particularly interesting for studies."

One of the most significant features of the cardiovascular edition is the Compressed Sensing Cardiac Cine application that Siemens Healthineers introduced to its MR machines 18 months ago, he explained.

"For cardiac MRI scans, an ECG signal is needed. This necessitates shaving and placing electrodes -- which takes time to set up and is a potential source of error. Using a beat sensor, we can track motion to prepare the MRI without an ECG: A surrogate signal via the surface coil determines the cardiac phase and trigger point," Fischer said.
