23NA-MRI OF THE HUMAN HEART USING A 3D RADIAL PROJECTION TECHNIQUE
Sodium MR1 hos the potentiell to differentiate viahle and non-viable infarcted myocardium.
The accurate quantijication ofthe total sodium content requires imaging techniques with ultra
short echo times below 0.5 ms. We prcsent a 3D-radial projection technique which allows
the acquisition of ECG-triggered sodium Images ofthe human heart with echo times ofO. 4
ms. A 3D-data sei ofthe heart ofa volunteer was acquired within less than 18 min on a
clinical Scanner (1.5 T), achieving a SNR oflO in the myocardium with an isotropic resolution …

Abstract
Sodium MR1 hos the potentiell to differentiate viahle and non-viable infarcted myocardium. The accurate quantijication ofthe total sodium content requires imaging techniques with ultra short echo times below 0.5 ms. We prcsent a 3D-radial projection technique which allows the acquisition of ECG-triggered sodium Images ofthe human heart with echo times ofO. 4 ms. A 3D-data sei ofthe heart ofa volunteer was acquired within less than 18 min on a clinical Scanner (1.5 T), achieving a SNR oflO in the myocardium with an isotropic resolution of W mm. This technique provides a toolfor clinical studies ofischemic heart diseases.
