Temporomandibular joint motion: efficacy of fast low-angle shot MR imaging.

摘要: One hundred temporomandibular joints (TMJs) in 62 symptomatic patients and two healthy volunteers were prospectively examined with T1-weighted spin-echo fast low-angle shot (FLASH) gradient-echo sequences. FLASH sequences performed during opening of the mouth provided a pseudodynamic depiction TMJ motion. In 49 joints, information that potentially influenced therapeutic approach to patient. This was not available from standard images. The additional fell into four general categories: (a) determination exact time disk recapture, (b) distinction normal variants pathologically displaced disks, (c) clarification discrepancies found between clinical examination results images, (d) elimination motion degradation
