Avirtual colonoscopyinvolves the use of eithercomputerized tomography(CT) ormagnetic resonance imaging(MRI). The colon is filled with either a liquid contrast agent or air, and CT or MRI is performed. Computerized reconstruction of either the CT or MRI images provides a virtual image that mimics ...

Finally, the implementation of rectal magnetic resonance imaging (MRI) as a staging modality has provided superior tissue contrast. Protocols have been optimized with high-resolution T2-weighted sequences, diffusion restriction, PET/MR, and the development of hepatobiliary MRI contrast agents that have...

In this respect, the pig is just another model and does not seem superior to the guinea pig, in particular since there are large differences between the anatomy of porcine and human colon. In addition, ganglia in the ISMP have a vastly different morphology and size; while ganglia in the ...
Anatomy of the lower gastrointestinal (digestive) system showing the colon, rectum, and anus. Other organs that make up the digestive system are also shown. Gastrointestinal stromal tumorscan occur in the colon. For more information, visitGastrointestinal Stromal Tumors Treatment. ...
With the proven benefits of minimally invasive surgery, there is steady growth in robotic surgery use and interest in novel robotic platforms. A miniaturized Robotic-Assisted Surgery Device (mRASD) has been in clinical use under a multi-center, investigational device exemption (IDE) study for right...
