Dynamic contrast-enhanced MRI for the assessment of spinal tumor vascularity: correlation with angiography.

Purpose: To determine if dynamic contrast-enhanced MRI (DCE-MRI) could correlate well with invasive angiography in the characterization of spinal tumor vascularity.

Methods: Totally 40 patients with untreated spinal tumors underwent MRI before preoperative angiography and embolization. Tumors were assigned to hypervascular, moderate, or hypovascular groups based on angiographic appearance.
