title: The diagnostic value of technetium 99m pertechnetate salivary gland scintigraphy in patients with certain salivary gland diseases.
abstract: OBJECTIVE
  To evaluate the diagnostic value of technetium 99m pertechnetate salivary gland scintigraphy in patients with certain salivary gland diseases.
  
  
  METHODS
  We evaluated 47 patients: 25 with chronic obstructive parotitis, 12 with sialolithiasis, and 10 with Sjögren syndrome. All of the patients underwent preoperative (99m)Tc-pertechnetate salivary gland scintigraphy. Patients with chronic obstructive parotitis also underwent ultrasonography, sialography, and sialoendoscopy; patients with sialolithiasis also underwent ultrasonography and computed tomography; and patients with Sjögren syndrome also underwent ultrasonography and sialography. We made comparisons between (99m)Tc-pertechnetate salivary gland scintigraphy and the other aforementioned diagnostic tests to investigate the role of (99m)Tc-pertechnetate salivary gland scintigraphy in diseases of the salivary glands.
  
  
  RESULTS
  In patients with chronic obstructive parotitis, (99m)Tc-pertechnetate salivary gland scintigraphy showed reduced excretion by the affected glands, whereas uptake was nearly normal. Among patients with sialolithiasis, (99m)Tc-pertechnetate salivary gland scintigraphy showed reduced excretion by the affected glands and decreased uptake in 5 patients. In patients with Sjögren syndrome, (99m)Tc-pertechnetate salivary gland scintigraphy showed a decrease in both excretion and uptake by the 4 glands.
  
  
  CONCLUSIONS
  Technetium 99m pertechnetate salivary gland scintigraphy played a substantial role in the diagnosis and differential diagnosis of salivary gland diseases.
