To investigate the value of 3D FIESTA sequence in magnetic resonance sialography (MRS) in the diagnosis of obstructive salivary diseases.
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.
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.
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.
探讨三维快速成像稳态进动序列（3D FIESTA）在磁共振涎管造影（MRS）诊断阻塞性涎腺疾病中的价值。
对11例阻塞性涎腺疾病患者进行MRS检查，将MRS数据进行后处理后获得涎腺导管的三维（3D）重建图像及虚拟内镜图像，并与涎腺内镜图像进行对比。
MRS对阻塞性涎腺疾病的诊断准确率为72.7%。虚拟内镜提供的视野与涎腺内镜高度一致。
MRS能够显示涎腺导管走行。磁共振虚拟内镜可为涎腺手术的术前评估提供与涎腺内镜检查相当的形态学及病理学资料。
