Analgesia for pelvic brachytherapy.
Pelvic brachytherapy presents the anaesthetist with numerous challenges. Patients vary from highly distressed young adults, to the elderly with coincidental disease severe enough to preclude surgery. The painful radioactive implants remain in place for a number of days. Treatment in isolated rooms reduces radiation exposure to staff, but makes close postoperative monitoring difficult, so the an...
متن کاملI-41: Pelvic MRI at Infertility
Compared with ultrasound, MRI has limited indications in evaluation of Female Infertility. Laparoscopy is the gold standard for the diagnosis of pelvic endometriosis. MRI is helpful in determining the extent of deep infiltrating endometriosis, especially when laparoscopic inspection is limited by adhesions. MRI allows for much more anatomic detail as well as better measurements of uterine fibro...
متن کاملI-45: Advance MRI Sequences in Pelvic Endometriosis
Background: To assess MRI in diagnosing endometriotic lesions, emphasizing T2*weighted imaging efficacy. Materials and Methods: This prospective study of 48 females (22-38 years, average 29.6) clinically suspected of endometriosis from September 2009 to April 2012. MRI was performed with a 1.5 T imager (Siemens) with a body array coil. T1, T2 and T2* weighted (2D-FLASH) sequences were obtained ...
متن کاملMRI/TRUS data fusion for brachytherapy
BACKGROUND Prostate brachytherapy consists in placing radioactive seeds for tumour destruction under transrectal ultrasound imaging (TRUS) control. It requires prostate delineation from the images for dose planning. Because ultrasound imaging is patient- and operator-dependent, we have proposed to fuse MRI data to TRUS data to make image processing more reliable. The technical accuracy of this ...
متن کاملNormal and variant pelvic anatomy on MRI.
The superior tissue contrast and flexible imaging planes afforded by magnetic resonance imaging (MRI) versus competing technologies permit optimal depiction of the pelvic viscera. Targeted protocols developed for specific pelvic visceral organs highlight important anatomic features that may not be imaged by other modalities. Therefore, a solid understanding of normal and variant pelvic anatomy ...
