Simultaneous T 1 and T 2 Mapping in the Brain With QuantoRAGE : An MP2RAGE Variant Using T 2 ‐Prepared Inversion

ABSTRACT Purpose To develop and validate a repeatable and reproducible approach, QuantoRAGE, for simultaneous whole‐brain T 1 and T 2 mapping using adiabatic magnetization preparation. Methods QuantoRAGE is a 3D FLASH‐based sequence using an adiabatic T 2 ‐prepared inversion foll...

Apparent Intramyocellular Lipid Index Using Spiral Magnetic Resonance Spectroscopic Imaging at 3 T

Abstract Purpose: This work introduces a rapid, high-resolution method based on spiral Magnetic Resonance Spectroscopy Imaging (MRSI) to map the apparent content of intramyocellular (IMCL) and extramyocellular (EMCL) lipids in human skeletal muscle. Methods: Unsuppressed water sp...

Evaluation of clinical performance of artificial intelligence-assisted measurement of thoracic aortic diameter on non-contrast CT

This study aimed to evaluate the clinical performance of artificial intelligence (AI)-assisted measurement of thoracic aortic diameter on non-contrast computed tomography (NCCT). This single-center prospective study included 79 patients (mean age = 70 ± 13 standard deviation; 46...

Diagnostic Accuracy of APTw and NOEw MRI Metrics for IDH Mutation and 1p/19q Codeletion Prediction in Gliomas

ABSTRACT Isocitrate dehydrogenase (IDH) mutation and 1p/19q codeletion are key molecular markers for glioma classification. Amide proton transfer weighted (APTw) and nuclear Overhauser effect–weighted (NOEw) markers showed promise for glioma characterization, by probing protein‐r...
