Better than Real: Complex-valued Neural Nets for MRI Fingerprinting

, 2017
The task of MRI fingerprinting is to identify tissue parameters from complex-valued MRI signals. The prevalent approach is dictionary based, where a test MRI signal is compared to stored MRI signals with known tissue parameters and the most similar ...

Comparative ergonomic workflow and user experience analysis of MRI versus fluoroscopy-guided vascular interventions:an iliac angioplasty exemplar case study [PDF]

, 2015
Purpose A methodological framework is introduced to assess and compare a conventional fluoroscopy protocol for peripheral angioplasty with a new magnetic resonant imaging (MRI)-guided protocol.

A Theoretically Guaranteed Deep Optimization Framework for Robust Compressive Sensing MRI

, 2018
Magnetic Resonance Imaging (MRI) is one of the most dynamic and safe imaging techniques available for clinical applications. However, the rather slow speed of MRI acquisitions limits the patient throughput and potential indi cations. Compressive Sensing (

MRI-targeted or standard biopsy for prostate-cancer diagnosis [PDF]

, 2018
Background Multiparametric magnetic resonance imaging (MRI), with or without targeted biopsy, is an alternative to standard transrectal ultrasonography-guided biopsy for prostate-cancer detection in men with a raised prostate-specific antigen level who ...

Pressure-anisotropy-induced nonlinearities in the kinetic magnetorotational instability [PDF]

, 2017
In collisionless and weakly collisional plasmas, such as hot accretion flows onto compact objects, the magnetorotational instability (MRI) can differ significantly from the standard (collisional) MRI.

MRI of the shoulder

Current Problems in Diagnostic Radiology, 1995
Magnetic resonance imaging of the shoulder is routinely used, especially in the evaluation of rotator cuff disease and glenohumeral instability. More recent studies have provided a more sophisticated understanding of what represents a pathologic rotator cuff.

Familial multiple cavernous malformation syndrome : MR features in this uncommon but silent threat [PDF]

, 2016
Cerebral cavernous malformations (CCM) are vascular malformations in the brain and spinal cord. The familial form of cerebral cavernous malformation (FCCM) is uncommon.

Real-time motion analytics during brain MRI improve data quality and reduce costs [PDF]

, 2017
Head motion systematically distorts clinical and research MRI data. Motion artifacts have biased findings from many structural and functional brain MRI studies.

Linear stability of magnetized massive protoplanetary disks

, 2014
Magneto-rotational instability (MRI) and gravitational instability (GI) are the two principle routes to turbulent angular momentum transport in accretion disks. Protoplanetary disks may develop both.
