A nuclear stress test called Lexiscan creates images of the heart muscle by using radioactive tracers. Your doctor can assess your heart's blood flow using the images created and look for any regions with abnormal or reduced blood flow. It is possible to use Lexiscan to identify or rule out coronary artery disease, evaluate its severity, and decide whether you are a candidate for angioplasty or bypass surgery. Users of Welzo can use this article for informational purposes to better understand Lexiscan.

Side Effects

The most typical adverse reactions to Lexiscan are:

head pain

- Weakness

- feeling faint or queasy

- flushing or skin that is red.

- dizziness or sickness

- breathing difficulties.

If you experience any of the following severe side effects, call your doctor right away:

- Chest ache

- an unsteady heartbeat

- trouble breathing

- losing consciousness or fainting.

The side effects of Lexiscan are generally well tolerated, but they do pose a slight danger. Before having the test, you should go over the risks and advantages with your doctor.


-The typical Lexiscan dose is 5 mCi (185 MBq).

How to consume:

- Through an IV line, Lexiscan is injected into a vein. Less than a minute should pass between injections. You must remain motionless on your back for roughly 20 minutes after the injection so that the tracer can circulate throughout your body.

How does Lexiscan work?

A tiny quantity of radioactive tracer is injected into a vein during the procedure for Lexiscan. The tracer is absorbed by the heart muscle after passing through the bloodstream. A specialized camera detects the gamma rays that the tracer emits and uses them to create images of the heart muscle. The images can be used to evaluate the heart's blood flow and identify any regions with abnormal or decreased blood flow. The Lexiscan test is non-invasive and doesn't call for any special preparation.


Nuclear medicine specialist interprets the images created by Lexiscan. Within 24 hours, the test's results will be made public. Most people agree that Lexiscan is reliable for making diagnoses.
