Abstract
Objective:To investigate diagnostic value of three-dimension contrast-enhanced magnetic resonance angiography(3D CE-MRA)in lesions of thoracic and abdominally great vessels.Methods:A retrospective analysis was performed on imaging and clinical data of 32 patients with lesion of thoracic and abdominally great vessels who admitted to Air Force Medical Center,PLA.during May 2016 and June 2025.All patients initially underwent conventional plain scan of magnetic resonance imaging(MRI).Subsequently,the Test Bolus technique with small dose was adopted to inject 2 ml of gadobenate dimeglumine via vein,and the time to peak of target blood vessel was tested,which was used to determine the delayed time of individual 3D CE-MRA scan.Three-dimensional T1-weighted fast low-angle shot(3D FLASH)sequence was used in this study,and the mask was collected as basic images of subtraction before injected contrast agent.Then,the dynamic enhanced scan was implemented according to predetermined delay time,so as to obtain thin-slice original images at arterial and venous phases,and automatically complete subtraction for mask.Two attending physicians at department of imaging were selected to analyze the original images and reconstructed images of the maximum intensity projection(MIP),so as to assess the morphology of the target vessels,and the lesion characteristics.Results:The obtained images of 3D CE-MRA for all patients at arterial and venous phases can clearly display main stem,and branches of 2-3 level of that of aorta.A total of 31 cases with positive lesion(96.9%)were found in 32 patients,which included 15 cases of abdominally aortic aneurysm(46.9%),6 cases of renal artery stenosis(18.8%),6 cases of Takayasu arteritis(18.8%),3 cases of atherosclerosis(9.38%),and 1 case of iliac artery aneurysm(3.13%).Conclusion:3D CE-MRA technique can non-invasively and clearly display the anatomical details and pathological features of thoracic and abdominally great vessels,which has importantly clinical value in diagnosing and preoperative assessing the lesions of thoracic and abdominally great vessels.关键词
