Sample text
In patients scheduled for a pelvic scan only, the start delay should be at least 60 s; practical experience suggests that 70–90 s are optimal. With this start delay, there is contrast enhancement of the iliac, external, internal, and common veins already at the beginning of the scan and it is thus possible to exclude venous thrombosis or tumor infiltration of the veins. Since perfusion of the pelvic organs such as the uterus is not a major diagnostic concern, it is not necessary to perform a scan of the early arterial phase.
The contrast medium may be injected manually or automatically. A strict injection protocol is not required when static contrast-enhanced images are acquired. However, a standardized injection protocol with use of an MR-compatible, automatic injector is recommended when dynamic studies are performed. In both cases, contrast medium injection should be followed by a saline flush of 20 ml to ensure that all of the rather small amount of contrast medium of about 10–20 ml reaches the central veins. 2 CT Scanning Technique There have been considerable technical advances in computed tomography in recent years.
Intracavitary coils yield a better image quality by improving the local SNR. The true pelvis, in particular the cervix, can be examined with an endorectal or endovaginal coil [1, 3, 5]. Intra- cavitary coils can be used alone or in combination with surface coil elements (phased array) as with MRI of the prostate. 4 Pulse Sequences The standard protocol for pelvic imaging comprises unenhanced T1- and T2-weighted sequences. The high soft tissue contrast of MRI is a prerequisite for the reliable detection and characterization of pathology in the female pelvis.
