Fig. 13.1 Normal whole-body bone scintigraphy Bone pain is a severe debilitating condition which frequently impairs the quality of life. Patients often receive analgesics, bisphosphonates, and external beam radiotherapy to…
Fig. 31.1 Appearance of the immunologic response in RA: interleukin-2 (IL2) and interleukin-4 (IL4) cytokines that are released from T-helper lymphocytes proliferate and activate the B lymphocytes. Activated B cells…
Fig. 10.1 On multiplanar reformatted oblique coronal image (a), proximal ulnar (white arrow) and radial head fractures (black arrow) are readily seen. Three-dimensional reconstructed image in bone window (b) demonstrates…
