A superscan is defined as a bone scan which demonstrates markedly increased skeletal radioisotope uptake relative to soft tissues in association with absent or faint genito-urinary tract activity. While a superscan is relatively uncommon its recognition is important as it is associated with a number of important underlying diseases. Total of 6027 bone scans were examined in a 5-year period and out of which 80 cases were diagnosed as superscan.
In bone imaging the term superscan has been used to describe the appearance of high skeletal uptake of radionuclide combined with low background activity Osmond etal 1975.

3D volume rendered images of the heart in a CT Coronary Angiogram study. A bone scan in which there is excessive skeletal radioisotope uptake in relation to soft tissues along with absent or faint activity in the genitourinary tract is known as a superscan. While the typical heterogeneous appearance of metastases normally is distinct from homogeneous uptake in metabolic bone disease the appearance of confluent disease a superscan can be quite similar as seen in the present patient 4-7.
Gleason score was 54 and PSA at diagnosis was 419 μgl. A superscan is a term given to the appearances on a nuclear bone scan when bony uptake of Tc99m disphosponate is so profound that the usual physiological uptake observed in the kidneys is no longer apparent. Radionuclide bone imaging is not specific but its excellent sensitivity makes it useful in screening for many pathologic conditions.
