Objectives:
The aim of this study was to evaluate the diagnostic accuracy of a specific protocol of computed tomography-colonography with intravenous contrast medium and urographic phase, which combined simultaneously the study of the intestinal and urinary tract, in the preoperative evaluation of women with deep infiltrating endometriosis (DIE) of anterior and posterior pelvic compartments.
Methods:
We retrospectively analyzed 73 women who underwent 74 computed tomography-colonography with intravenous contrast medium and urographic phase examinations for strong clinical suspicion of DIE. All the women had surgical confirmation.
Results:
Computed tomography-colonography with intravenous contrast medium and urographic phase in detecting DIE rectosigmoid involvement had a sensitivity of 82.3% and a specificity of 66.7%, while in detecting DIE urinary tract involvement had a sensitivity of 45.9% and a specificity of 78.4%.
Conclusions:
Computed tomography-colonography with intravenous contrast medium and urographic phase is a useful technique for the preoperative planning of selected women with DIE, in particular, for the detection of sigmoid colon and bladder lesions especially when performed with a dose reduction protocol.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
01:26Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
