Fig. 13From: Magnetic resonance imaging (MRI) in rectal cancer: a comprehensive reviewMeasurement of extramural tumour growth is dependent on the plane of imaging. True transverse TSE (a, 3 T) image shows the extramural tumour growth to be 9 mm (white line). Reformatted image from original 3D T2-weighted images with plane reconstructed perpendicular to the rectal wall (b, 3 T) shows that the extramural tumour component can be 20 mm (dotted line)Back to article page
