Question

Which of the following would NOT enhance during the first several minutes of a post contrast CT study of the neck?

1) vascular lesion
2) lymph nodes
3) jugular vein
4) internal carotid artery

Answer 1

The internal carotid artery would NOT enhance during the first several minutes of a post contrast CT study of the neck.

Step-by-step explanation:

The internal carotid artery would NOT enhance during the first several minutes of a post contrast CT study of the neck.

During a post contrast CT study, contrast dye is used to highlight specific structures in the body. The contrast dye is injected into the bloodstream and enhances the blood vessels when it reaches them.

In the case of a post contrast CT study of the neck, the vascular lesion, lymph nodes, and jugular vein would all enhance because they are part of the blood vessel system in the neck. However, the internal carotid artery, which supplies blood to the brain, would not enhance because it is located inside the skull and not part of the neck anatomy being studied.
