Diagnostic value of 31P magnetic resonance spectroscopy (MRS) and velocity encoded MRI (VEC-MRI) in suspected diastolic dysfunction with normal myocardial mass. – Comparison to ec…

Purpose: To evaluate the diagnostic role of VEC-MRI combined with 31P-MRS in hypertensive patients compared to echocardiographic and tissue Doppler results. Material and Methods: 30 patients (19 men and 11 women, mean age 59±11 years) were prospectively studied by echocardiography and velocity encoded MRI (VEC-MRI) in order to calculate E/A ratio and deceleration time of the early diastolic filling curve (DT(E)). Results of both modalities were correlated. Patients in whom VEC-MRI was not able to distinguish normal diastolic function from pseudonormalization decisively additionally underwent 31P-MRS.
