Switched surface coil system for bilateral MR imaging.

摘要: A method is presented for acquiring magnetic resonance (MR) images in parallel from both members of a pair organs, such as the temporomandibular joint (TMJ), with use two surface coil receivers. Interleaved sagittal sections are broken into groups, one on each side head, and MR receiver toggled between coils. The that not receiving at given time decoupled other by active gating diode blocking network located across input. This produces effective decoupling independent loading positioning makes it possible to same coils already employed single-coil reception. Clinical application 95 patients (190 joints) symptoms internal derangement TMJ demonstrated 24% average decrease total patient examination time, even after addition coronal imaging procedure. In no case was there sacrifice diagnostic quality.
