[Morphological imaging for response assessment in metastatic bone disease].

Response assessment with morphological imaging in metastatic bone disease is difficult. X-Ray is useful only for long bones. CT is the best imaging modality for assessment of osteolysis and osteosclerosis. MRI is the gold standard for bone marrow morphological imaging. Morphological MR imaging using basic sequences, especially T1, provides confident evaluation of the behaviour of lesions under therapy. Radiotherapy and interventional radiology may induce cortical and bone marrow changes.
