Figure 3. (a) T2 weighted sagittal fast-spin-echo scan showing a large cervical tumour with high T2 signal. The oblique scan line demonstrates the plane that is required to obtain a true axial representation of the cervix as in Figure 3b. (b) Oblique T2 weighted fast-spin-echo scan. There is preservation of the normal low T2 signal intensity of the cervical stoma (arrows). The preservation of this line has a negative predictive value exceeding 96 for parametrial invasion.
