Fig. 4From: Comparative analysis of the value of amide proton transfer-weighted imaging and diffusion kurtosis imaging in evaluating the histological grade of cervical squamous carcinomaThe correlation between histological grading and different parameters. The ADC (a) and MD (c) are also well correlated with grades (r = − 0.644, − 0.732, P <  0.001), while MTRasym (d) and MK (b) are strongly correlated with pathological grade (r = 0.789, 0.743, P <  0.001)Back to article page
