| Research Abstract |
The smallest commercially available surface coi(3cm in diameter) and an experimental small rectangular surface coil(1x3cm) were and applied on the SIGNA HORIZON 1.5T MR system to investigate the ability to image small structures in the dermal and/or subcutaneous areas. The field of view of 4x4cm was selected. For the experimental coil, first spin echo imaging with repetition time 1,500ms, echo time 19ms, slice thickness 2.0mm, image matrix 256x160 was thought to be suitable to image the surface areas of the interphalangeal jnd wrist joints, although this coil was only applied on normal volunteers and had no chance with patients. However, comparison of the results between the experimental and commercial coils helped to establish the best routine clinical imaging techniques about the small surface areas. Because of the small size of the coil, positioning of the patients(volunteers) was the most critical factor. We intend to continue the study and wish to help for a new smaller commercial coils in near future.
