Tumour

In most published studies, cross-sectional imaging techniques (CT , ultrasound, MRI) are more accurate in staging advanced (T3, T4) than early (T1, T2) diseases, and the staging of  early disease remains a challenge. In gut tumours, endoscopic ultra - sound is more accurate than CT or MRI in the local staging of  early disease (T1, T2) by virtue of  its ability to demonstrate the layered structure of  the bowel wall and the depth of tumour penetra tion ( Figure 8.41 ). Developments in MRI may also improve the staging accuracy of  early disease. MRI is extremely valuable in bone and soft-tissue tumour staging and in intracranial and spinal disease. - Tumour
