Validation of F-FDG PET/MRI and diffusion-weighted MRI for estimating the extent of peritoneal carcinomatosis in ovarian and endometrial cancer -a pilot study.

Background: The extent of peritoneal carcinomatosis is difficult to estimate preoperatively, but a valid measure would be important in identifying operable patients. The present study set out to validate the usefulness of integrated F-FDG PET/MRI, in comparison with diffusion-weighted MRI (DW-MRI), for estimation of the extent of peritoneal carcinomatosis in patients with gynaecological cancer.

Methods: Whole-body PET/MRI was performed on 34 patients with presumed carcinomatosis of gynaecological origin, all scheduled for surgery.

MR follow-up of small experimental intracranial haemorrhages from hyperacute to subacute phase.

Purpose: To compare pulse sequences in revealing intracranial bleeding from the hyperacute to subacute phase.

Material And Methods: We injected 0.3-1 ml of autologous blood into the brain of 8 rabbits.
