In brief: Only at certain time

Bulky lesions in the retroperitoneum or masses growing off the bowel are frequently visualized.
The same holds true for metastatic lesions to liver and lung. When we work up a patient for extensive surgical resection and want to be sure no metastatic focus is present to be addressed or might obviate the surgical procedure, a PET/CAT scan is employed where any malignant lesion lights up.
