Celiac plexus block: evaluation of injectate spread by three-dimensional computed tomography.
We describe a case of pancreatic cancer in which the spread pattern of injectate during neurolytic celiac plexus block was evaluated by three-dimensional helical computed tomography. Three-dimensional images provide excellent visualization of the spread patterns of injectate in a target site, which appears to provide patients with effective relief from intractable pain.

Double contrast magnetic resonance (MR) imaging using superparamagnetic iron oxide (SPIO) and gadolinium (Gd) is performed to detect and characterize focal liver lesions. However, this technique is a costly and lengthy process. The purpose of this study was to determine the usefulness of SPIO-enhanced MR imaging including SPIO-enhanced T1-weighted imaging in diagnosing focal liver lesions. ⋯ The ferumoxides set was useful for the detection of focal hepatic lesions. Ferumoxides-enhanced T1-weighted imaging may replace delayed-phase gadolinium-enhanced T1-weighted imaging in the diagnosis of hepatic metastasis and cysts.
