Abstract

Purpose

To establish direct 17O-magnetic resonance imaging (MRI) for metabolic imaging at a clinical field strength of 3 T.

Methods

An experimental setup including a surface coil and transmit/receive switch was constructed. Natural abundance in vivo brain images of a volunteer were acquired with a radial three-dimensional (3D) sequence in the visual cortex and in the heart with electrocardiogram (ECG)-gating.

Results

In the brain, a signal-to-noise ratio of 36 was found at a nominal resolution of (5.6 mm)3, and a transverse relaxation time of T2* = (1.9 ± 0.2) ms was obtained. In the heart 17O images were acquired with a temporal resolution of 200 ms.

Conclusion

Cerebral and cardiac 17O-MRI at natural abundance is feasible at 3 T.
