First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether giving a personalized dose of a radioactive tracer (rubidium-82) based on a patient's weight can improve the quality of PET heart scans. Researchers will enroll 48 adults with known or suspected heart disease and divide them into four weight groups. The goal is to see if this weight-based dosing produces clearer images across all body sizes.
