MR imaging of motion with spatial modulation of magnetization.
TLDR
This technique can be used to study heart wall motion, to distinguish slowly moving blood from thrombus, and to study the flow of blood and cerebrospinal fluid.

Combination of compressed sensing and parallel imaging for highly accelerated first‐pass cardiac perfusion MRI
TLDR
Comp compressed sensing and parallel imaging are combined by merging the k‐t SPARSE technique with sensitivity encoding (SENSE) reconstruction to substantially increase the acceleration rate for perfusion imaging and a new theoretical framework is presented for understanding the combination of k-t SParSE with SENSE based on distributed compressed sensing theory.

TLDR
Dynamic computed tomography using rapid-sequence scanning can be used to determine cerebral blood flow noninvasively following an intravenous bolus injection of contrast material, as this area is proportional to the fractional vascular volume of the tissue.

Heart wall motion: improved method of spatial modulation of magnetization for MR imaging.
TLDR
It is demonstrated in this study that the substitution of more RF pulses, with their relative amplitudes distributed according to the binomial sequence, results in sharper stripes, allowing the use of a two-dimensional grid of stripes for more detailed studies of heart wall motion and provides a unique method of analyzing regional ventricular myocardial strain.

Tracking and finite element analysis of stripe deformation in magnetic resonance tagging
TLDR
A method for tracking stripe motion in the image plane, and how this information can be incorporated into a finite element model of the underlying deformation of a silicone gel phantom subjected to a well-controlled 3-D deformation is described.

Three‐Dimensional Left Ventricular Deformation in Hypertrophic Cardiomyopathy
TLDR
HCM patients had reduced 3D myocardial shortening on a regional basis; however, LV torsion was increased, and the principal strain associated with 3D maximal contraction was slightly depressed in many regions.
