Table 2 Apparent diffusion coefficient (ADC) and intravoxel incoherent motion (IVIM) parameter values of the primary tumour between patients without nodal involvement, those with sub-centimetre involvement, and those with size-significant involvement. ADC: apparent diffusion coefficient (x 10− 3 mm2/s); D: pure diffusion coefficient (x 10− 3 mm2/s); f: perfusion fraction. PLN: pelvic lymph node

From: Diffusion-weighted magnetic resonance imaging of primary cervical cancer in the detection of sub-centimetre metastatic lymph nodes
