Abstract:
Objective To explore the clinical application value of MRA (TOF and PC)in cerebrovacular arteriovenous malforma-tion imaging when DAS as a reference gold standard.Methods 60 patients clinically suspected cerebral vascular malformations were enrolled in our study.They were all underwent MRA (TOF and PC)and DSA examinations successively within three days.Then, the imaging of feeding arteries,vascular malformation masses and venous drainages were compared and analyzed.Results Of all 60 patients with AVM,their feeding arteries and arterioles images were showed better by DSA and MRA-TOF technology than by MRA-PC.The difference was statistically significant (χ2/P DSA?PC - 4.1 75/0.000,χ2/P TOF ?PC - 3.508/0.000 ),no statistically difference was found between DSA and MRA-TOF findings,(χ2/P DSA?TOF -0.740/0.459).However,their venous drainages and venules show better with DSA and MRA-PC technology than with MRA-TOF method,the difference was statistically significant (χ2/P DSA?TOF -2.445/0.014,χ2/P PC?TOF -3.443/0.001),no statistically difference was found between DSA and MRA-PC findings (χ2/P DSA?PC -1.085/0.278).Conclusion MRA-TOF to display cerebral arteries and MRA-PC to show cerebral venues are basically consistent with the DSA,MRA-TOF and MRA-PC cannot replace each other when showing cerebral arteries and venous.
