Magnetic resonance imaging

MAGNETOM Aera 1.5T is a high-field magnetic resonance tomograph equipped with tunnel aperture of 70 cm which is comfortable for a patient during the procedure. MAGNETOM Aera 1.5T utilizes Tim + Dot + Trueform technologies. Tim technology allows for a combination of more than 204 elements of various rolls and selectable scanning area without repositioning of the patient, while Dot technology automatically selects the optimal scanning protocol for each subject. TrueForm forms cylindrical field of magnet uniformity to increase diagnostic value of images. The field is even throughout the scanning area, which allows for the increased investigational region and it helps to obtain high-quality images. Altogether, these methods help to the accuracy of diagnosis and improve comfort for patients under investigation.

Capacities of tomograph are enhanced due to the use of novel scanning sequencing   and visualization analysis including heart function programme analysis; flow volume/velocity programme analysis, highly-specific myocardial tissue innovation analysis (Т1- Т2- Т2*- mapping); myocardial viability analysis adapted to use quantitative and volumetric assessment of fibrosis areas; myocardial perfusion analysis adapted to use visual and semi quantitative assessment;
