Sialography:
- a- contrast examination for sublingual gland
- b- only oily contrast medium can be used
- c- 4-5 cc of contrast is the obtimum dose
- d- ductal stones is one of the indications.
The correct answer is: d. ductal stones is one of the indications.
Here's the reasoning and explanation for each option:
a. Contrast examination for sublingual gland:
This is true. Sialography can examine all three major salivary glands, including the sublingual gland.
b. Only oily contrast medium can be used:
This is false. Both water-soluble and oily contrast media can be used for sialography. Water-soluble media is generally preferred due to its ease of injection and lower viscosity. Oily media might be used in specific situations where leakage from the duct is a concern.
c. 4-5 cc of contrast is the optimum dose:
This is true. While the optimal dose can vary depending on the gland size and individual patient, 4-5 cc per gland is typically considered the standard range.
d. ductal stones is one of the indications:
This is true. In fact, diagnosing ductal stones (small, hard deposits blocking the salivary ducts) is a major reason for performing sialography.
Therefore, based on the accurate information and specific focus on indications, d. ductal stones is one of the indications is the most fitting answer.
