Multi-Gated acquisition (MUGA): About your scan
This handout explains a multi-gated acquisition (MUGA) scan. This diagnostic test shows how well your heart works when you are resting. It is often used for people who are going to start chemotherapy treatment, which involves medicines that may be toxic to the heart. Sections include "How should I prepare?" "How does the scan work?" and "What should I expect during and after the scan?"
