Hochauflösende Dünnschicht-CT zum präoperativen Staging beim Rektumtumor: Vergleich mit der endo-luminalen Sonographie und der Histologie

Rectal carcinomas are amongst the most common malignant tumours. The aim of this work was to determine whether high resolution CT with thin sections (1 mm) can provide satisfactory delineation of perirectal tumour infiltration. Correct determination of local tumour spread was possible in four out of nine patients and distinction between those tumours confined to the rectal wall and those infiltrating the perirectal tissues was possible in four out of eight patients.
