Superscan
Updates to Article Attributes
Body
was changed:
Superscan is intense symmetric activity in the bones with diminished renal and soft tissue activity on a Tc99m diphosphonate bone scan.
Pathology
This appearance can result from a range of aetiological factors:
- diffuse metastatic disease
- prostatic carcinoma
- breast cancer
- transitional cell carcinoma (TCC)
- multiple myeloma (some difference in opinion)
-
lymphoma
- patchy uptake nonetheless: look at skull and ribs
- tends to somewhat spare the distal skeleton
- metabolic bone diseases
- renal osteodystrophy
- hyperparathyroidism 1 (often secondary hyperparathyroidism)
-
osteomalacia
- will involve distal skeleton
- smoother uptake
- myelofibrosis/myelosclerosis
- mastocytosis
- wide spread Paget disease
Radiographic appearance
A metastatic superscan tends to have uptake throughout the axial skeleton and proximal appendicular skeleton, often somewhat heterogeneous. In contrast, a metabolic superscan tends to be more uniform and involve both the axial and more peripheral skeleton, including the distal extremities, calvarium, and mandible.
