What Does This Bone Scan Indicate?
I was given a copy of my bone scan on a CD. The viewer on the CD is Efilm Lite. In the center there is a large white spot that appears as bright as a large light bulb. It disappears if I move the sidebar down but then it leaves a void there. No other portion of the image changes except this large spot. When it is visible it is labeled as WB enhanced dual intensity and when the void is visible it says WB masked. What is this spot and what is its significance? Thanks. Edit: I was expecting an answer from a radiologist since I was at the Ask a Radiologist page , now it says a family physician is waiting to answer.

Hi,
In a typical bone scan technique, the patient is injected (usually into a vein in the arm or hand, occasionally the foot) with up to 740 MBq of technetium-99m-MDP and then scanned with a gamma camera, which captures planar anterior and posterior or single photon emission computed tomography (SPECT) images.[17][18] In order to view small lesions, SPECT imaging technique may be preferred over planar scintigraphy.[19]
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. AJEET SINGH, General & Family Physician
