Multimodality MR Imaging,64-slice CT Coronary Angiography In Diagnosis Of CHD And Assessment Of Revascularization

Objective :â‘ To discuss the value of the combination CTA and multimodality MR scanning technology in diagnosis of CHD.â‘¡To discuss the recent therapeutic effect of viable myocardium after PTCA+stenting with multimodality MR scanning.Methods:â‘ 28 patients were underwent 64-slice CTA and cardiac multimodality MR scanning,and the results were compared with CAG.â‘¡12 patients were underwent cardiac multimodality MR scanning before CAG and between one to two weeks after PTCA+stent.Results:â‘ The results of detecting medium and severe coronary stenosis by 64-slice CTA and MR myocardial perfusion had no statistical significance compared with CAG.â‘¡Original abnormal perfusion segments,left ventricular motion and function were improved after stenting by cardiac multimodality MR scanning.Conclusion:â‘ If combinate 64-slice spiral CTA and cardiac multimodality MR scanning,we can assess CHD conveniently,completely,accurately and non-invasiely.â‘¡Cardiac multimodality MR scanning can assess short-term therapeutic effect from cardiac morphous,motion and myocardial perfusion after revascularization.
