Abstract
In our study 106 patients with colorectal tumors were examined using combined positron-emission and computer tomography before surgical treatment and after complex therapy. Malignancies of the colon were characterized by the wall thickening or infiltration with inhomogeneous uptake of the contract media and increased uptake of18F-deoxyglucose. In metastatic lymph nodes the typical features were size growth and increased metabolism. In patients with hepatic metastases there were increase of18F-deoxyglucose uptake and focal decrease in density. If recurrences were found, an additional tissue with increased inhomogeneous18F-deoxyglucose uptake could be seen. Use of combined positron-emission and computed tomography can provide more accuracy in staging colorectal malignancies. After complex treatment recurrences and distant metastases can also be found more precisely.
