Pre- and post-androgen deprivation therapy images from planar bone scintigraphy (anterior view). Anterior images from planar bone scintigraphy of one patient at baseline (a) and after 6 months of satisfactory androgen therapy (b). PSA decreased from 92 ng/mL at baseline to 8.8 ng/mL (90 % reduction), and plasma-testosterone decreased from 1.7 to 0.07 ng/ml. All lesions initially suspected of malignancy in the axial skeleton demonstrated partial or complete regression, whereas lesions in large joints and small joints in the hands and feet were stable or progressed. The activity in the left elbow region is an artifact caused by contamination at tracer injection
