Objective

Advances in MR hardware performance and imaging techniques have enabled us to perform subsecond frame rate contrast enhanced MR angiographies as a clinical routine resulting in subtraction angiographies with temporal resolutions similar to those obtained by conventional DSA. In this manuscript, we describe the technique of 2D-dynamic contrast-enhanced MR subtraction angiography and its possible applications in neurosurgery.

Methods

A T1 weighted gradient-echo sequence with ultra-short TR and TE values was performed during the intravenous bolus application of MR contrast media. This sequence was run continuously for about 70 seconds with a temporal resolution of 0.34 seconds per image.

Results

In all 30 investigated cases and all pathological entities separation of early and late arterial phases, capillary phases, early and late venous phases was possible. The proximal portions of the major cerebral arteries, the capillary blush and the venous anatomy including the tributaries to the large sinuses could be well defined.

Conclusions

Dynamic contrast enhanced MR angiography will prove helpful in the detection and follow-up of arteriovenous malformations, including their arterial feeders, size of the nidus and their venous drainage pattern, b) the demonstration of dural arteriovenous fistulas, which can be recognised as a early filling of a dural sinus during the early arterial phase, and, c) the characterization of the degree of vascularisation of brain tumours.
