text: there is physiologic distribution of radiotracer in the soft tissue and bilateral kidneys.? hi, i am a 24 year old male. i got a bone scan done in june 2006 and the results said:   there is physiologic distribution of radiotracer in the soft tissue and bilateral kidneys.  what does this all mean? can you please help me out? can you please explain everything because i have no idea what any of this means. i looked everywhere for answers and got no luck. how serious is this? what can i do for it? i would very greatly appreciate this. thank you. when you were injected with the isotope, it goes into your blood stream and is processed through the kidneys-- what they are looking for is any abnormal uptake in your bones- spine, pelvis, extremities.  i'm not sure about the soft tissue unless there was infiltration at the injection site.  i assume you read the report off your chart- ask your doctor who ordered the scan to explain everything to you.  only he can tell you what is abnormal....dont lose sleep....
