Multislice CT fluoroscopy: technical principles, clinical applications and dosimetry.

Purpose: The aim of this study is describing fluoroscopic techniques with multislice CT during interventional procedures. We emphasize the technical principles of the multislice CT fluoroscopy and the relative advantages in clinical application, in comparison to single slice fluoroCT and conventional CT guided procedures. Other topics are dosimetry and patient's and operator's radioprotection.

Abdominal recurrence of ovarian cancer: value of abdominal MR in patients with positive CA125 and negative CT.

Purpose: To evaluate the role of abdominal MR in the diagnosis of ovarian cancer recurrence in patients with increasing serum Ca-125 levels and negative abdomino-pelvic CT scan.

Materials And Methods: In a period of about 30 months, 22 patients in follow-up for ovarian carcinoma (stages II, III-IV) with increasing levels of Ca-125 and negative abdomino-pelvic CT scan were studied with abdomino-pelvic MR. All patients had a disease-free interval of at least 6 months after cytoreductive surgery and chemotherapy.
