补充资料:磁共振成像
磁共振成像 magnetic resonance imaging 利用人体组织中某种原子核的核磁共振现象,将所得射频信号经过电子计算机处理,重建出人体某一层面的图像的诊断技术。又称核磁共振成像术。英文简称MRI。
MRI在临床上主要用于以下部位:①头部。可清晰分辨脑灰质和白质,对多发性硬化等一类脱髓鞘病优于CT。对脑外伤、脑出血、脑梗塞、脑肿瘤等同CT类似,但可显示CT为等密度的硬膜下血肿。脑梗塞或脑肿瘤的早期,CT不能查出,而MRI有可能显示。对钙化和脑膜瘤显示不好。脑干及小脑病变的MRI图像由于没有伪影是首选检查方法。②脊柱。不需要造影剂就能清晰区分脊髓、硬膜囊和硬膜外脂肪。对肿瘤、脊髓空洞症、脱髓鞘病变等均有较高诊断价值。显示骨折或脱位不如常规X射线或CT,但能观察脊髓损伤情况。显示椎间盘较好,可以分辨纤维环和髓核,特别是矢状面图像可以同时显示多个椎间盘突出。③四肢。对骨质本身病变显示不如常规X射线或CT。对软组织及肌肉病变包括肿瘤及炎症都能清晰显示,特别是对早期急性骨髓炎,是一种灵敏度很高的检查方法。也是检查膝关节半月板病变的首选方法。④盆腔。对直肠及泌尿生殖系统优于CT,无辐射损害,特别适用于孕妇及胎儿检查。⑤胸部。对肺的检查不如常规X射线,对纵隔检查则优于CT,不用造影剂即可分辨纵隔血管和肿物,也是一项有价值的心血管检查技术。⑥腹部。主要用于肝、胰、脾、肾等实质脏器。 |
