Magnetic resonance imaging (MRI) has rapidly become an important tool in clinical
medicine and biological research. Its functional variant (functional magnetic resonance …

Progress has recently been made in implementing magnetic resonance imaging (MRI)
techniques that can be used to obtain images in a fraction of a second rather than in …

Specified regions of the myocardium can be labeled in magnetic resonance (MR) imaging to
serve as markers during contraction. The technique is based on locally perturbing the …

An adaptive technique for measuring and correcting the effects of patient motion during
magnetic resonance image acquisition was developed and tested. A set of algorithms that …

Brain tissue movements were studied in axial, sagittal and coronal planes in 15 healthy
volunteers, using a gated spin echo MRI sequence. All movements had characteristics …

A technique for measuring blood flow by whole body nuclear magnetic resonance is
described. This method uses imaging gradient profiles that combine even echo rephasing …

Cardiovascular magnetic resonance (CMR) phase contrast imaging has undergone a wide
range of changes with the development and availability of improved calibration procedures …

The accuracy of volume flow rate measurements obtained with phase‐contrast methods was
assessed by means of computer simulation and in vitro experiments. Factors studied include …

We review the current status of liquid flow velocity studies by pulsed nuclear magnetic
resonance (NMR). NMR is a non-invasive method that is most sensitive to protons, so that …

A surface coil on the neck causes adiabatic fast passage in blood as it flows by through a
magnetic field gradient. This allows separation of blood and stationary tissue images of the …
