| [ Summary ] |
We outline the usefulness and limitations of evaluating colorectal cancer through use of FDG-PET (PET/CT) scanning, in relation to categories such as detection of primary lesions, lymph node metastasis or recurrence, as well as detection of distant metastasis. PET (PET/CT) scanning is effective for detecting metastases and recurrence rather than evaluation of primary tumors. It is especially useful for finding unexpected lesions as compared to other imaging modalities. 3D images reconstructed by fused contrast enhanced CTs and FDG-PET scans are used to produce navigation images. These images may be used to detect hypermetabolic tumors and vascular structures simultaneously. They are useful for preoperative mapping to clarify the correlationship of tumors and blood vessels. |
