Magnetic resonance imaging. (A1, A2) Representative apparent diffusion coefficient (ADC) slices of control and ECM-embedded scaffolds, respectively. Boxed regions mark areas for which diffusion coefficients were calculated. (A3) Graph showing ADCs for the control and ECM scaffold. Data represent mean±SD of the values from the five boxed regions. (B1, B2) Representative T1 relaxation slices for control and ECM-embedded scaffolds, respectively. Boxed regions mark areas for which T1 relaxation times were calculated. (B3) Graph showing T1 relaxation times for the control and ECM scaffold. Data represent mean±SD of the values from the five boxed regions. (C1, C2) Representative T2 relaxation slices for control and ECM-embedded scaffolds, respectively. Boxed regions mark areas for which T2 relaxation times were calculated. (C3) Graph showing T2 relaxation times for the control and ECM scaffold. Data represent mean±SD of the values from the five boxed regions.
