Lab Panels and Radiology

This discussion has two questions: answer both questions.

1. Laboratory. Why do you think the AMA created lab panels? When you comment on fellow students’ posts, do you agree with their posts and why or why not?
2. Radiology. Some radiology codes include the phrase “with contrast”, “without contrast” and “without contrast followed by contrast” What is contrast and Wwhat purpose does contrast serve? What should a radiologist take into consideration when he/she decides to use contrast? Give examples. When you comment on fellow students’ posts, are their examples sound? Why or why not, and if not, explain.
