Invasive Tests

Medical procedures that involve entering the body to diagnose heart conditions. These tests include cardiac catheterisation, angiography and various scanning techniques using radioactive tracers.

Explaining the Angiography Technique

How angiography uses X-rays and catheters to examine blood vessels and detect heart and circulation problems.

Undergoing Cardiac Catheterisation

A guide to cardiac catheterisation, a procedure doctors use to examine your heart and blood vessels in detail.

Undergoing Radionuclide Tests

Radionuclide tests use small amounts of radioactive chemicals to show how well your heart is working and check for heart disease.

What Are Electrophysiological Tests?

How doctors use electrophysiological tests to detect dangerous heart rhythm problems that other imaging can't find.

What Does a Thallium Stress Test Involve?

A thallium stress test uses exercise or medication to see how blood flows to your heart and detect coronary artery blockages.

What Is Perfusion Scanning?

Perfusion scanning uses medical imaging to check how blood flows through your heart and brain to spot blockages or damage.
