Deep-learning-based contrast synthesis in knee magnetic resonance imaging: performance across multiple target contrasts.

INTRODUCTION Quantitative MRI has been held back, because it increases scan time on top of clinical protocols. In this cross-sectional study, we explore how accurately unmeasured contrasts can be synthesized from magnetic resonance fingerprinting (MRF) data. MATERIALS AND METHODS MRF, T1-weighted (T1w), gadolinium-en...

Simultaneous 3‐D Adiabatic T1ρ, T2*, and Quantitative Susceptibility Mapping for Characterization of Myocardial Infarction in Ex Vivo Mouse

To develop a T1ρ‐weighted quantitative susceptibility mapping (QSM) technique for simultaneous imaging of T1ρ and T2* relaxation and magnetic susceptibility in ex vivo mouse hearts after myocardial infarction (MI). MI was induced in C75Bl/6JOlaHsd mice, and their hearts (nMI = 7, nCTRL = 6) were imaged ex vivo by combi...
