Nov 25, 2009 · Super scan (superscan) refers to the diffuse skeletal uptake of MDP with resultant low or absent activity in the kidneys and bladder and high ratio of bone to soft tissue activity. The superscan effect presents a technical challenge in the evaluation of lesions on bone scans in prostate cancer clinical trials. CONCLUSION In conclusion, the absence of a superscan finding in bone scans does not rule out extensive bone metastases. Sometimes, they use the term “bone scan” when using the test to look at only one specific joint or bone rather than your whole body. A large camera (called a gamma camera) scans you and picks up radioactivity.

A bone scan looks at the bones to see if there are any abnormalities, such as a fracture, tumour or infection. Diffuse increased uptake on bone scan: super scan Semin Nucl Med. Healthcare providers sometimes refer to DXA scans as bone density scans, DXA scans or bone density tests. Superscan is home to the Siemens Force CT Scanner. Intense osteoblastic activity in the bones causes diminished renal and background soft tissue uptake. 1 About 40–60% of the injected Tc-99m MDP is excreted in the urine. Our CT uses only 10% of the radiation dose of other CT Scanners used in Sydney, whilst retaining the highest quality images.
