‘Sub-superscan’ in Bone Scan – An Important Feature of Extensive Bone Metastases

ABSTRACT

@#A Superscan is described as a ‘beautiful bone scan’. In a superscan, the uptake of 99mTc-Methelene Diphosphonate (MDP) is prominent in the skeleton relative to soft tissue with absent or faint visualisation of the kidneys. This finding could be misinterpreted as a normal bone scan. A ‘Sub-superscan’ is a term used for scan findings in which the uptake is atypical of a superscan, but the patient has extensive bone metastases, as presented in our case report.
