Quantitative Transient-state Imaging (QTI) is a non-random, dictionary-less MR Fingerprinting alternative. Through iterative reconstructions, QTI recovers a series of contrast-weighted images from transient-state acquisitions and subsequently estimates the parameters that best describe the resulting dynamic signal evolutions. Here, we extend the QTI framework by incorporating a simple velocity...

Mapping of quantitative MRI relaxation values is promising for improving the assessment of musculoskeletal disease. Magnetic Resonance Fingerprinting (MRF) is a new method that enables fast quantitative MRI by exploiting the transient signals caused by the variation of pseudorandom sequence parameters. This proof-of-concept work demonstrates the utility of MR Fingerprinting in the knee. ...

Magnetic Resonance Fingerprinting (MRF) promises quantitative tissue analysis based on the relaxation times. Spiral undersampling is employed with MRF to yield short scan times. However, it is prone to blurring artifacts in the presence of field inhomogeneities, especially if both aqueous and fatty tissues are present. In this contribution, we extend MRF to quantify the fat signal fraction and...
