ABSTRACT
PURPOSE:
The purpose of this study is to evaluate the gadolinium-enhanced MR imaging findings of cerebral venous angiomas, and to compare those findings with those of cerebral angiography. MATERIALS ANDMETHODS:
We reviewed the findings of gadolinium-enhanced MR images of 11 cases with angiographically proved cerebral venous angiomas. We obtained Tl-and T2-weighted images with gadoliniumenhanced Tl-weighted images at a 0.5 T MR imager with a spin-echo technique. We analyzed the location and signal intensity of the lesion, pattern of contrast enhancement, the distribution of draining veins and medullary veins before and after contrast enhancement, and then compared with the findings of cerebral angiography.RESULTS:
The characteristic central tubular signal void structure showed low signal intensity on Tl-weighted images and high signal intensity on T2-weighted images in all cases. After gadolinium enhancement, we could find a characteristic enhancement of all medullary and central veins in 7 cases.CONCLUSION:
Gadolinium-enhanced MR image was useful in the diagnosis of venous angiomas especially in the detection of medullary veins. The invasive cerebral angiography could be replaced by this technique in this disease.
