It is also established that T2 weighted images are most important in detecting parametrial invasion of cancer.20 In present study, MRI findings suggestive of parametrial invasion included inhomogeneous signal intensity of cervical stroma, focal and complete disruption of hypointense cervical stromal ring on T2 weighted images, peritumoural fat stranding and tumour bulging into parametrial fat or the presence of soft tissue mass/tumour in parametrial tissue.
Statistics derived from the inhomogeneous K-function in its bivariate form (Kcross.inhom) were used to assessment of spatial interactions (Baddeley et al., 2000).
