Group 3: Nine patients had increased blood flow and blood pool phases, and Patient 3 had increased blood pool but not increased blood flow. All patients had areas of focal uptake on Single Photon Emission Computed Tomography (SPECT) but no bony abnormality on Computed Tomography (CT). A positive (+ve) result indicates increased tracer uptake in the phase of the bone scan as designated in the Table heading.
