Aim. The aim of the study is to evaluate the quality of the temporal mandibular joint (TMJ) imaging in patients with lack of condyle-disk coordination with the Half-Fourier Acquisition Single Shot Turbo Spin Echo (HASTE), and compare it with the quality of TSE T2-weighted images.
Methods. Twenty-seven patients were selected (12 men and 15 women; age range 17-69 years) with medical history negative for facial trauma or surgery. The instrument used was a Siemens 1.5 Tesla with bilateral coil dedicated for studying both TMJs. TSE T2-weighted and HASTE images in the parasagittal axis with open and closed mouth were obtained for both joints.
Results. The quality of the TSE T2-weighted images was betterr for all parameters considered (both at open and at closed mouth) than the HASTE images; however, the latter method is considerably quicker.
Conclusion. HASTE was found to be a valid method for use as rapid screening to study the TMJ and for use in patients who are unable to maintain an immobile position. Time and cost required for the examination are drastically reduced.
