Comparative StudyFast multiplanar spoiled gradient-recalled imaging of the liver: pulse sequence optimization and comparison with spin-echo MR imaging.
The purpose of this study was to optimize a new rapid-acquisition MR pulse sequence, called fast multiplanar spoiled gradient-recalled (FMPSPGR) imaging, for breath-hold imaging of the liver and to compare unenhanced and contrast-enhanced FMPSPGR with standard spin-echo imaging in detecting liver tumors. ⋯ FMPSPGR is a new, ultrafast MR sequence that provides T1-weighted images of the liver during suspended respiration. Contrast-to-noise ratio and liver signal-to-noise ratio are significantly improved over those on conventional spin-echo T1-weighted images. The combination of breath-hold FMPSPGR with gadopentetate dimeglumine is an excellent technique that can be used to rapidly evaluate the liver with superior overall image quality. Contrast-to-noise ratios are generally superior to T2-weighted spin-echo images, making this technique a useful adjunct to conventional spin-echo MR imaging.

A celiac plexus block performed via an anterior approach offers several potential advantages over a posterior approach, including shorter procedure time, less discomfort to the patient, and less risk of neurologic complications. We evaluated the use of an anterior approach to determine its efficacy and safety. ⋯ The anterior approach to a celiac plexus block is a safe and effective means of pain control in patients with pancreatic carcinoma. It offers several potential advantages to the posterior approach, and should be considered for all patients with pain caused by pancreatic carcinoma that is refractory to pain medication.
