[67Ga-scintigraphic finding of colorectal carcinoma; the basis of clinicopathologic viewpoint]

Twenty-seven cases of colorectal carcinoma were evaluated by 67Ga-scintigraphy on the basis of clinicopathologic viewpoint. On each cases, 67Ga-scintigraphy was performed just before the operation, and resected specimen was also examined after the operation. In 17 cases (63%), the lesions were demonstrated on preoperative 67Ga-scintigraphy, on the other hand, all the lesions were clearly detected on images taken from resected specimen. Thus, it seems to be no doubt to accumulate 67Ga-citrate to colorectal carcinoma, and 67Ga-scintigraphy appears to be more useful imaging modality to detect the disease when the routine detectability becomes more higher because of some technical application.
