Case 004 (NPO Guidelines): A 72-year-old patient is scheduled for a contrast-enhanced CT of the chest at 10:00 AM. The patient ate breakfast at 7:30 AM. According to current ACR guidelines regarding fasting before IV contrast, what should the technologist do?

Reschedule the exam for later in the day to ensure a full 8-hour fast. Proceed with the exam since current ACR guidelines do not mandate routine fasting before IV iodinated contrast. Administer an antiemetic before the contrast injection to prevent aspiration. Convert the study to a non-contrast CT to avoid aspiration risk.

Correct Answer:

Proceed with the exam since current ACR guidelines do not mandate routine fasting before IV iodinated contrast.
