Abstract:
:Subcutaneous fat provides excellent contrast for water density tissue. Five patients with subcutaneous metastases visualized on computed tomography (CT) scans are presented. In some cases, CT proved to be the optimal diagnostic modality for visualizing these lesions and documenting their response to therapy.
