Changes in the distributions of fluorine-18-labelled fluoro-2-deoxy-d-glucose accumulation into tongue-related muscles after dissection in patients with tongue cancer

To elucidate the changes in the distributions of fluorine-18-labelled fluoro-2-deoxy-d-glucose ( F-FDG) accumulation in the tongue muscles of patients following four kinds of surgical operations for tongue cancers. The changes in the distributions of F-FDG accumulations in the tongue muscles on posi...

Description
Summary:To elucidate the changes in the distributions of fluorine-18-labelled fluoro-2-deoxy-d-glucose ( F-FDG) accumulation in the tongue muscles of patients following four kinds of surgical operations for tongue cancers. The changes in the distributions of F-FDG accumulations in the tongue muscles on positron emission tomography (PET)-CT, in association with imaging findings on CT and MRI, were retrospectively analyzed before and after four kinds of surgical operations for 50 patients with tongue cancers. F-FDG-PET-positive areas appeared at the back of the intrinsic muscles of the tongue after invasive surgery for tongue cancers despite the absence of abnormal findings on CT and MRI. A correlation between the standardized uptake value maximum of F-FDG in the intrinsic muscles and the degree of invasiveness of the surgical procedures for tongue cancers (r = 0.539, p
