正电子发射体层显像(PET)和磁共振成像(MRI)是继PET/CT之后将功能和解剖结构显像融合的新技术。与CT相比,MRI有更高的软组织对比度和空间分辨率,且无辐射,因此PET/MRI检查有其独特的优势,经过临床的逐步应用,目前已取得了初步的进展。由于女性生殖系统器官均位于盆腔并且全部是软组织器官,特别适合应用PET/MRI检查。PET/MRI在妇科恶性肿瘤的诊断、术前评估及术后随访方面都有独特的优势,特别在宫颈癌与子宫内膜癌的肿瘤体积、淋巴结转移判定等方面优于PET/CT。
Positron Emission Tomography (PET) and Magnetic Resonance Imaging (MRI) are new technologies that fuse functional and anatomical imaging after PET / CT. Compared with CT, MRI has higher soft tissue contrast and spatial resolution, and no radiation, so PET / MRI has its unique advantages, after clinical application gradually, has made initial progress. Because the female reproductive system organs are located in the pelvic and all soft tissue organs, especially suitable for PET / MRI examination. PET / MRI has unique advantages in the diagnosis, preoperative evaluation and postoperative follow-up of gynecologic malignancies. PET / MRI is superior to PET / CT in determining tumor volume and lymph node metastasis of cervical cancer and endometrial cancer.
