Question:
For NM exams that are chosen based on single-day imaging vs two or more days— how do you consider the following? Imaging at four hours on Monday, imaging at 24 hours on Tuesday. Are you counting as a single day for a 24-hour period or as 2 days based on calendar days? Is there an official reference that may be sourced?
Answer:
If imaging is performed at four hours and then again at 24 hours, this would be considered imaging on two days. See Radiology Test Case in Clinical Examples in Radiology Volume 8 issue 3, Summer which is published by the AMA.
