[The percutaneous placement of intra-arterial catheters with "reservoirs" for subcutaneous infusion. The technic and preliminary results].
We report our personal technique and the preliminary results of percutaneous implantation of intraarterial catheters connected to a subcutaneous infusion reservoir (Port-a-cath) for the regional chemotherapy of hepatic and extrahepatic tumors. January, 1996, to February, 1997 fifty patients underwent the procedure: 44 had liver cancers (42 had metastases and 2 hepatocellular carcinomas), 4 pelvic tumors (2 bladder carcinomas, one uterine cancer and one vaginal cancer), one had inoperable pancreatic tumor and one breast cancer. ⋯ In conclusion, the percutaneous placement of intraarterial catheters for continuous regional chemotherapy is a feasible, safe and tolerable procedure and can represent an alternative to the surgical implantation of catheters in the hepatic artery for the treatment of liver metastases from colorectal cancer. The technique opens new therapeutic possibilities for the local treatment of extrahepatic tumors (such as gynecologic, vesical, pancreatic and breast cancers), even though its clinical efficacy must be assessed in selected trials.

Comparative Study[Magnetic resonance study of patellofemoral cartilage with a fat-suppressed T1-3D gradient-echo sequence: a comparison with other acquisition technics at medium field strength].
We compared GRE T1 3D FS sequence with other acquisition techniques available on medium field strength MR units (.5 T) in patellofemoral cartilage studies. ⋯ GRE T1 3D FS sequences are the MR acquisition technique of choice in the assessment of the hyaline cartilage of the knee, even at medium field strength.
