Sarcoidosis: correlation of extent of disease at CT with clinical, functional, and radiographic findings.

abstract：:Vertebral mineral loss (measured by computed tomography) was compared to peripheral mineral loss (measured by photon absorptiometry) in immobilized monkeys. Significantly greater loss was found in axial cancallous bone than in peripheral cortical bone. The accuracy of vertebral CT measurements in one animal was determ...
