| ***What percentage of bone destruction is needed to show up in a bone scan? A bone scan will show something is wrong _____ weeks earlier than xrays? | only 3% of bone destruction is needed to show up (this isn't much), bone scans show something is wrong 2-3 weeks earlier than xrays |
| What is the best form of diagnosis? | MRI |
| What percentage of bone destruction is needed to show up on a MRI? Does a MRI have ionizing radiation? | A MRI only needs 3% bone destruction to show up (same as a bone scan). And of course a MRI is non-ionizing, its the best remember and Dr. Poirier is in love with them! |
