[Determining the linear dimensions of the heart in healthy persons by the method of magnetic resonance tomography].

Abstract

Linear dimensions of hearts in 16 healthy volunteers obtained by magnetic resonance tomography (MRT) and 2-dimensional echocardiography (EchoKG) were compared. MRT was performed with BMT 1100 tomograph ("Bruker", FRG) with magnetic field strength of 0.235 T using EKG-triggering. Oblique slices through anatomic heart axes were registered. Good correspondence of MRT- and EchoKG-obtained linear dimensions of heart structures (r = 0.62-0.85) prove that MRT allows evaluation of dimensions of various heart structures as effectively as 2-dimensional EchoKG.
