F\u00fcr die lokale Tumorausdehnung ist die MRT beim Rektumkarzinom sehr gut geeignet. Beim Kolonkarzinom gibt es in der CT deutliche Einschr\u00e4nkungen hinsichtlich der Sensitivit\u00e4t f\u00fcr die Unterscheidung einzelner Stadien. Lymphknotenmetastasen k\u00f6nnen eine gro\u00dfe Herausforderung f\u00fcr beide Bildgebungsmethoden sein, daher wurden mehrere Malignit\u00e4tskriterien definiert.
