Abstract
Colorectal carcinoma is one of the leading causes of death from cancer in industrialized countries .The percentage of patients who develop local or distant recurrence following curative surgical resection is relatively high, probably due to the presence of neoplastic foci that remain undetected at the time of surgery. The early diagnosis of local and distant recurrence is important in that further surgery, chemotherapy and radiotherapy separately or combined is an integrated multidisciplinary approach, may improve
survival and quality of life .Unfortunately no standardized follow us strategy has been yet developed for patients with rectal cancer treated with curative resection. PET/CT is a relatively new imaging technology, whose undoubted advantages are valuable in clinical oncology as well as in all fields of diagnosis,staging, and treatment. The hardware combination of anatomy and function has been the true evolution in imaging. Although initial staging at the time of diagnosis is often performed
during colostomy, PET-CT imaging is recommended for patients at high risk (with elevated CEA levels) and normal CT and for whom surgery can be avoided if FDG-PET shows metastases. Screening for recurrence in patients at high risk has also been advocated. Our study involved 25 patients (16 males and 9 females) with age range from 1971years.All patients had histopathological diagnosis of colorectal carcinoma obtained from biopsy whatever surgically of image guided
