MR microscopy of the articular cartilage with a 1.0T permanent magnet portable MR system: preliminary results.

The present study was designed to evaluate the use of a 1.0T portable permanent magnet MR system in obtaining microscopic MR images of the hyaline cartilage in vitro. A clear laminar appearance was demonstrated with this system.

MR microscopy of articular cartilage at 1.5 T: orientation and site dependence of laminar structures.

Objective: To evaluate MR microscopic images of normal-appearing porcine hyaline cartilage ( n=15) in vitro obtained with an MR microscope using an independent console system (MRMICS) at 1.5 T.

Design And Results: The MRMICS is a portable imaging system consisting of a radiofrequency system, gradient power supplies and a personal computer.
