TL;DR: To evaluate the validity of different approaches to determine the signal‐to‐noise ratio (SNR) in MRI experiments with multi‐element surface coils, parallel imaging, and different reconstruction filters, a large number of experiments were conducted with single‐element coils and parallel imaging.

TL;DR: The statistical distribution of background noise was analyzed for MR acquisitions with a single-channel and a 32-channel coil, with sum-of-squares (SoS) and spatial-matched-filter (SMF) data combination, with and without parallel imaging using k-space and image-domain algorithms, with real-part and conventional magnitude reconstruction and with several reconstruction filters.

TL;DR: Using an adequate fit method may substantially improve the sensitivity of T2 to detect pathology in cartilage and change in T2 follow‐up examinations.

TL;DR: In vivo DT imaging of patellar cartilage is feasible, has good test-retest reproducibility, and may be accurate in discriminating healthy subjects from subjects with osteoarthritis, and two promising biomarkers for early OA.

TL;DR: A combined intravoxel incoherent motion–diffusion tensor imaging (IVIM‐DTI) methodology is used to distinguish structural from flow effects on renal diffusion anisotropy.
