Comparative Study Clinical Trial
Staging of colon cancer: whole-body MRI vs. whole-body PET-CT--initial clinical experience.
To assess the accuracy of whole-body MR imaging (WB-MRI) in comparison with whole-body [18(F)]-2-fluoro-2-deoxy-D-glucose (FDG) PET-CT in staging patients with diagnosed colorectal carcinoma (CRC). ⋯ WB-MRI is a feasible method for examining colon cancer patients but cannot displace the present role of PET-CT.
-
To evaluate the accuracy of Multi-detector row CT (MDCT) for the prediction of tumor invasion of the mesorectal fascia (MRF). ⋯ Multi-detector row CT has a poor accuracy for predicting MRF invasion in low-anterior located tumors. The accuracy of CT significantly improves for tumors in the mid-high rectum. There is a high inconsistency among readers.
-
To evaluate 16-slice CT portography technique and appearances of cavernous transformation of portal vein (CTPV) and the correlation with surgical procedure of orthotopic liver transplantation (OLT). ⋯ Using 16-slice CT portography can noninvasively diagnose CTPV. The appearances of CTPV on the 16-slice CT portography can provide helpful information for surgeons to make an accurate preoperative decision. MIP is the optimal technique for displaying CTPV.

We assessed the imaging features of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas paying special attention to underlying pancreatic fibrosis on three-phase helical computed tomography (CT) and dynamic magnetic resonance (MR) imaging. ⋯ Three-phase helical CT and dynamic MR imaging were useful in the diagnosis of IPMN of the pancreas.

The aim of this study is to report our experience in diagnosis of the opium body packers with CT scan. ⋯ CT scan could be a suitable imaging modality in identifying opium packets, similar to that reported for cocaine and heroin.
