TUESDAY, Dec. 5 (HealthDay News) -- The combination of two imaging techniques -- positron emission tomography and computed tomography -- provides quicker and more precise information to guide the treatment of colorectal cancer, German doctors report.
Exact and complete information on the "stage" -- or severity -- of a tumor is critical, said the physicians at University Hospital Essen. Typically, getting that information requires a series of imaging sessions, each one supplying a segment of the picture.

The German study compared the use of newly available positron emission tomography (PET)/computed tomography (CT) devices to older, conventional techniques for diagnosis of 47 patients with colorectal cancer.
CT alone correctly diagnosed 52 percent of the cancers, the report said. CT followed by PET was accurate in 64 percent of the cases. But the PET/CT combination was 22 percent more accurate in defining the exact stage of the tumor.
Most important, the PET/CT combination was most successful in designing treatment for individual patients, the report said. It changed therapy management in four of the patients.
"Based on the results of our study, we have integrated PET/CT colonography in our daily clinical routine," said Dr. Gerald Antoch, associate professor of radiology at Essen, and lead author of the report.
But Antoch cautioned that the study "must be considered preliminary," and "further studies are required to confirm these results in a larger patient cohort."
Such a study will be done at Essen, Antoch said.
"Whole-body PET/CT colonography as an all-in-one staging modality seems feasible to provide an alternative to the multimodality, multi-step staging in patients with colorectal cancer," the report stated. "It is less time-consuming than a conventional multi-step approach... Thus, it represents a psychological and physical advantage when considering the burden to the patient."
