Technological development in Therapeutic applications of alternating electric fields: Review [PDF]

, 2012
A number of bacteria, virus and other unhealthy cells need to be killed for getting rid of them. For more than a century antibiotics have been effectively used for killing bacterial pathogens and chemical drugs against the cancer cells.

OpenMRF: A Modular, Vendor‐Neutral Open‐Source Framework for Magnetic Resonance Fingerprinting Using Pulseq

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Widespread adoption and methodological advancement of magnetic resonance fingerprinting (MRF) are limited by the lack of unified, reproducible implementation frameworks and fragmented open‐source tools. To address these barriers, we introduce OpenMRF—a comprehensive Pulseq‐based solution—designed to enable standardized and transferable

Respiratory‐Resolved Isotropic 3D T1 Mapping of the Carotid Vessel Wall With B1+ Correction (CARISMAT1C)

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop, optimize, and characterize a respiratory motion‐resolved free‐running isotropic 3D carotid vessel wall T1 mapping technique named CARISMAT1C. Methods An inversion‐recovery gradient‐echo free‐running pulse sequence with interleaved double flip‐angle (2FA) was implemented, and an extended‐phase‐graph dictionary was used to ...

A Rapid T1‐Independent Sequence for Cerebrospinal Fluid Water Standard Correction: Application to Improved Proton Density Mapping in Brain

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve brain water content measures relative to cerebrospinal fluid (CSF) by including a rapid T1‐independent sequence to correct for CSF T1 errors. Methods Proton density (PD) was estimated from a 3D multiple echo gradient echo sequence by extrapolating to TE = 0 and then correcting for T1 losses using a T1 map from 3D MP2RAGE. To

A Modular Hybrid Framework for CEST MRI Development and Clinical Translation Using pTx‐Pulseq Preparation With Open‐ and Closed‐Source Readouts and ONNX Mapping

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Chemical exchange saturation transfer (CEST) MRI offers unique metabolic insights for imaging of cancer, stroke, or neurodegeneration. However, the rapid expansion of CEST preparation schemes and evaluation techniques creates a bottleneck; novel methods often remain complex prototypes requiring offline processing, preventing clinical ...
