FDG PET/MRI in Synchronous Uterine Adenocarcinoma and Leiomyosarcoma

Shiho Yokoo et al.

Summary: A 52-year-old woman suspected of uterine sarcoma underwent F-18-FDG PET/MRI, which revealed a myometrial mass and an endometrial lesion, suggesting dual primary neoplasms. Based on the PET/MRI findings, the intraoperative procedure was modified to determine the necessity of pelvic lymphadenectomy. PET/MRI was more useful than PET/CT in diagnosing and differentiating between the two malignant neoplasms in the uterus, due to the high contrast resolution and precise fusion of MRI.

[18F]FDG PET/MRI in rectal cancer

Filippo Crimi et al.

Summary: [18F]FDG PET/MRI shows high sensitivity and accuracy for staging/restaging rectal cancer patients, particularly in detecting malignant nodes for N staging and liver metastases for M staging. It is recommended for post-chemoradiotherapy restaging and selecting patients for rectum-sparing approaches.
