What is a Lexiscan Nuclear Stress Test and How Does It Work?
Table of Contents
A Lexiscan nuclear stress test is a special test for the heart. It uses a drug called Lexiscan and nuclear imaging to check blood flow. It’s great for people who can’t do hard exercise.
For this test, a tiny bit of radioactive tracer is put into your blood. It goes to your heart and is seen by cameras. The Lexiscan drug makes your heart work like it does during exercise.
Then, the cameras take pictures of your heart. These pictures show if there are any problems with blood flow. Your doctor can see these pictures to find out what’s going on with your heart.
