Comparative study of MSCTA with DSA in the blood supply of meningiomas

Evaluation of multi-slice CT angiography (MSCTA) and digital subtraction angiography (DSA) was made through the comparison of the two methods in the detection of the blood supply of meningiomas, providing further clues for improved application of MSCTA and DSA in the blood supply of meningiomas. MSCTA is more advantageous in the depiction of three-dimensional relationships between the tumor and peripheral vessels and skull. And, compared to DSA, MSCTA is noninvasive, faster and cheaper.
