脑梗塞的磁共振成像与临床

THE MAGNETIC RESONANCE IMAGING OF CEREBRAL INFARCTION AND ITS CLINICAL STUDY

本文讨论了80例脑梗塞磁共振成像与临床表现,其中20例有CT检查。多数病例磁共振成像显示为多发性脑梗塞(95%)。梗塞灶在T_1加权是低信号改变;T_2加权呈高信号改变,急性和慢性期特点一致。资料结果表明:磁共振成像定位准确(98.75%)。病灶检出T_2比T_1敏感,磁共振成像检出病灶多于CT。在诊断脑梗塞方面,磁共振成像优于CT。

The magnetic resonance imaging of cerebralinfarction and its clinical study were discussed in 80 pa-tients (20 with CT). Most of the cases were multipleinfarction on magnetic resonance imaging (95%).T--weighted image (T_1) of infarction showedlow--signal intensity and T_2--weighted image (T_2) didhigh--signal intensity. The same character was seen inacute and chronic stage. The result revealed that 1oca-tion of magnetic resonance imaging was correct (98.75%)and T_2 was more sensitive than T_1 in demonstratinginfarction More lesions with magnetic resonanceimaging were observed than those with CT. Magneticresonance imaing was better than CT in diagnosis of cer-ebral infarction.
