From a recent study printed in Medscape in 2008:
- A 3 phase bone scan may be helpful in revealing findings typical for the diagnosis of RSD. A false negative (misses RSD diagnosis in symptomatic people) is fairly common
- It is considered sensitive and specific particularly if done < 20 wks of onset. But a study by Werner reported sensitivity at 44%
- Sensitivity reported at 60% by Kozin, et al.
And a 2007 article from Orthopedics Today:
- The sensitivity of a 3 phase bone scan decreases with duration of the disease
- It has poor sensitivity, approximately 50%
So, not a great test for RSD, what is? It's a mixed bag. But do it sooner than later if you're going to do it at all and understand that this test will not be sensitive enough 50% of the time for RSD. In constrast, bone scanning is something like 97% sensitive when looking for bone tumors.
