How is metastatic workup?

Chest Radiography : AP and lateral CXR are enough CT chest:  Can detect small lesions of 2mm (might be benign) Abdominal CT:  Detect retroperitoneal involvement (lymph nodes < 2cm) Cannot distinguish fibrosis, teratoma, or malignancy MRI of the brain: if multiple lung metastases, or high β-hCG PET: No apparent advantage over CT (done in specific cases) Repeat tumor markers after 1 month of surgery They are very important for F/U Staging is done based on pathology result of radical orchiectomy, tumor markers and imaging results
