To prove the usefulness of Magnetic Resonance Imaging (MRI) in determining the invasion of uterine cervical cancer with imaging planes, we evaluated 44 patients with histologically proved cervical cancer. MRI was performed with a Signa 1.5 T (General Electric), and a T2-weighted image was used. In coronal planes, the accuracy was 75.0% for parametrial invasion. It was impossible to diagnose in 77.8%, 92.1% and 63.2% the invasion of the uterine body, bladder and rectum, respectively. In axial planes, the accuracy was 76.3%, 92.1% and 78.9% for the invasion of parametrium, bladder and rectum, respectively. It was impossible to diagnose in 72.2% the invasion of the uterine body. In sagittal planes, the accuracy was 80.6%, 97.4% and 89.7% for invasion of the uterine body, bladder and rectum, respectively. In all 39 cases it was impossible to diagnose parametrial invasion. In five cases, MRI failed to detect the tumor in any of the three planes, but in three cases it was able to detect the tumor in at least one of the three. We conclude as follows: 1) MRI is a useful method in determining the invasion of cervical cancer. 2) Coronal planes are recommended for the determination of parametrial invasion, axial planes for the parametrium, bladder and rectum, and sagittal planes for the uterine body, bladder and rectum. 3) All three planes are needed to determine cervical cancer.
为了通过成像平面来证明磁共振成像（MRI）在确定子宫颈癌浸润情况方面的实用性，我们对44例经组织学证实为子宫颈癌的患者进行了评估。使用通用电气公司的Signa 1.5T磁共振仪进行MRI检查，并采用T2加权图像。在冠状面，对宫旁浸润的诊断准确率为75.0%。分别有77.8%、92.1%和63.2%的病例无法诊断子宫体、膀胱和直肠的浸润情况。在轴位，对宫旁、膀胱和直肠浸润的诊断准确率分别为76.3%、92.1%和78.9%。有72.2%的病例无法诊断子宫体的浸润情况。在矢状面，对子宫体、膀胱和直肠浸润的诊断准确率分别为80.6%、97.4%和89.7%。在所有39例病例中均无法诊断宫旁浸润情况。有5例病例在三个平面中均未检测到肿瘤，但有3例病例至少在三个平面中的一个检测到了肿瘤。我们得出以下结论：1）MRI是确定子宫颈癌浸润情况的一种有用方法。2）推荐使用冠状面来确定宫旁浸润，轴位来确定宫旁、膀胱和直肠情况，矢状面来确定子宫体、膀胱和直肠情况。3）确定子宫颈癌需要所有三个平面。
