Abstract:
ObjectiveTo prospectively investigate the feasibility of contrast material-enhanced magnetic resonance angiography(CE-MRA)for visualization of the spinal vasculature.MethodsTen volunteers and fifteen patients with thoracic or lumbar disk herniation underwent contrast-enhanced MR angiography of the thoracoabdominal aorta and posterior branches.Examination Was performed with three-dimensional CE-MRA technique and 0.3 mmol/kg of gadolinium contrast agent Was administrated.ResultsIn all examinations,the Adamkiewicz artery,the anterior spinal artery(ASA),and their connections witll the aorta were identified.The Adamkiewicz artery originated between T8 and L3 in all examinations and derived from the left side of the aorta in 80% of all examinations.ASA was able to be observed from T6 to L3.The diameter of Adamkiewicz artery Was 0.6-1.2 mm and ASA was 0.6-1.0 mm.Conclusion CE-MRA Can be used to lOCalize Adamkiewicz artery and provide accurate information for clinical approach.
