A whole-body CT scan documented multiple lymph node, liver, subcutaneous, bone, and muscular metastases, a right femoral venous thrombosis, a left popliteal arterial thrombosis, and splenic and renal infarcts.

Whole-body CT scans provide an advantage in terms of comparison because all organs are in the primary beam of the irradiated area.
