Figure 1. (a) ⁹⁹Tc^m MDP bone scan demonstrating increased tracer uptake around an osteolytic area in the proximal end of right humerus and mild increased uptake in the right sacroiliac (SI) joint. (b) ⁹⁹Tc^m(V)DMSA whole body scan of the same patient showing focal concentration in the same region corresponding to that seen in bone scan. (c) Multiplanar MRI of the pelvis showing a tiny focus of high signal intensity in the iliac aspect of the right SI joint in an axial short tau inversion recovery sequence suggestive of metastatic deposit. (d) ⁹⁹Tc^m MDP bone scan and (e) ⁹⁹Tc^m(V)DMSA whole body scan post therapy (chemotherapy and external radiotherapy over the right upper humerus) showing significant reduction of tracer uptake commensurate with the patient's clinical improvement.
