Synopsis

Spinal artery imaging has long been difficult in clinical detection and assessment of spinal vascular lesions, due to its anatomical complexity and very small diameter. Compared with DSA and CT, CE-MRA technology has the advantages of safety, noninvasive and radiation free. Traditional MR sequences, such as TOF and PC, perform poorly with lower SNR. Here, accuracy of B-TFE and 3D T1-FFE sequences were compared to provide radiologists a better choice in the spinal artery scenario. The results indicated that 3D T1-FFE would be preferred than B-TFE. And B-TFE should be used merely when patients are sensitive to contrast media
