Bone scan-there is a round area of slight increased blood pool activity below the heart measuring approximately 77 by 56mm. what does it mean?

Need more informatio: Tell us your history, diagnosis and why you had the bone scan done in the first place?. Without this info, we are not able to help you or explain what the bone scan report means. Basically Bone scan is test to check the health of the bones. Your report says nothing about the bones. So I assume your bone scan is normal. But what else is going on, needs more information.
