Introduction: None written.

The sensitivity and specificity of findings for Sialolithiasis are listed below. See the left navigation bar to change the display.

Finding	Sensitivity	Specificity	Comments, Study
CT Scan	Sensitivity = 100%		high-res, non-con Study: AJR Am J Roentgenol 1982 Sep;139(3):547-54. PMID 6981322
MRI Sialography	100%	80%	this visualizes the ducts. Stones are invisible on MR. Sens/spec vary based on MR modality. Study: Radiology 2000 Sep;216(3):665-71. PMID 10966693
Ultrasound	80%	80%	Study: Radiology 2000 Sep;216(3):665-71. PMID 10966693
X-Ray	Sensitivity = 60%		for parotid stones. For submandibular stones, sensitivity is 80-95% (just based on radio-opaqueness). Study: UTD: http://www.utdol.com/online/content/topic.do?topicKey=prim_ent/7995
