Intravoxel incoherent motion imaging of the kidney: alterations in diffusion and perfusion in patients with renal dysfunction
S Ichikawa, U Motosugi, T Ichikawa, K Sano… - Magnetic resonance …, 2013 - Elsevier
PURPOSE: To investigate the relationship between estimated glomerular filtration rate
(eGFR) and parameters calculated using intravoxel incoherent motion (IVIM) imaging of the
kidneys. MATERIALS AND METHODS: We studied 365 patients, divided into 4 groups
based on eGFR levels (mL/min/1.73 m2): group 1, eGFR≥ 80 (n= 80); group 2, eGFR 60–80
(n= 156); group 3, eGFR 30–60 (n= 114); and group 4, eGFR< 30 (n= 15). IVIM imaging was
used to acquire diffusion-weighted images at 12 b values. The diffusion coefficient of pure …
