Application of 3D FIESTA sequence in magnetic resonance sialography for obstructive salivary diseases / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the value of 3D FIESTA sequence in magnetic resonance sialography (MRS) in the diagnosis of obstructive salivary diseases.</p><p><b>METHODS</b>Eleven patients with obstructive salivary diseases underwent MRS, and three-dimensional (3D) reconstruction and virtual endoscopic images of the salivary gland ducts were obtained after MRS data post-processing for comparison with those of sialoendoscopy.</p><p><b>RESULTS</b>The diagnostic accuracy of MRS was 72.7% for obstructive salivary diseases. The virtual endoscopy provided a visual field highly consistent with that by sialoendoscopy.</p><p><b>CONCLUSION</b>MRS is capable of visualizing the tracts of salivary glands. MR virtual endoscopy can provide sufficient morphological and pathological data for preoperative assessment of salivary operations with sialoendoscopy.</p>
