Diagnosis is determined through X-rays, three phase bone scan, skin tests, joint fluid analysis, and thermo graphic studies. Sometimes the phentolamine test is used. Thermography is more sensitive than any other diagnostic tool when diagnosing RSD according to Dr. H. Hooshmand. He states that diagnosing RSD without thermography is like diagnosing a heart attack without an EKG. It should be noted that the CT scan, EMG, and MRI studies may be normal during the first stage of RSD. Along with the tests, signs and symptoms of RSD are taken into account. All the pieces of the puzzle must fit to render a proper diagnosis.
NOTE: In some parts of Canada, thermography is available but other areas do not have this diagnostic tool. We are trying to get better diagnostic tools which will mean earlier diagnosis of RSD and faster, more efficient treatment.
