心内间隔缺损MRI、B超诊断与手术结果对比分析

目的：评价ＭＲｌ、Ｂ超对先天性心脏病心内间隔的显示能力，并结合手术结果，探讨ＳＥ序列垂直室间隔短轴位和一种快速梯度回波的心脏单层面多时相、多层面单时相、多层面多时相（Ｆａｓｔｃａｒｄ）的临床应用价值。材料与方法：２９例先天性心脏病心内间隔经ＭＲＩ、Ｂ超检查并与手术结果对照，结果：ＭＲＩ诊断出全部的心内间隔缺损及伴发畸形；Ｂ超漏诊了一例ＡＳＤ及１例伴发的部分肺静脉畸形引流。结论：ＭＲＩ对先天性心脏病心内间隔缺损具有重要的诊断价值和意义，而且Ｆａｓｔｃａｒｄ与ＳＥ序列相结合能明显提高诊断效果；垂直室间隔短轴位能显示房间隔和室间隔的全貌，应作为诊断心内间隔缺损的常规体位。

Comparison and Analysis of MRI,Echocardiography and Operation,Results in Septal Defect

Purpose:To assess the ability of MRI and echocardiocardiography in depicting the septal defect ;Todetermine the role of the short axial perpendicular to septum and a fast gradient-recalled-echo sequence with car-diac-triggered segmented acquisition (Fastcard) in diagnosing septal defect. Materials and Methods:29 casesof the septal defect were examined by MRI and Echocardiography. The results were compared with operative find-ings.Results: Of the 29 cases,MRI detected all septal defects and associated anomalise.4 cases of ASD and 1cases of associated partial pulmonary venous return were missed by echocardiography. Conclusion: MRI had im-portant diagnostic value in diagnosis for the septal defect. Fastcard is a powerful complement of SE in diagnosing septal defect.The short axial perpendicular to septum is superior to other planes in revealing small septal defect.[
