The researchers developed a multi-contrast pulse sequence that successively generates T1-weighted, proton density-weighted and then T2-weighted contrast in each repetition time.

For two of the six MR sequences – the proton density-weighted gradient echo (GE) sequence and the inversion recovery gradient echo (IRGE) sequence – they saw signatures in the MR image that were ...

Example triple turbo spin-echo brain MRI scans in (A) neurotypically developing and (B) atypically developing extremely preterm–born adolescents. Proton density (PD)–weighted, T2-weighted, and ...

Nina Lummel, MD, from the University of Munich, and colleagues analyzed coronal and sagittal 2mm proton-density weighted MRI sequences from 50 healthy volunteers using different MRI field ...

(d) Sagittal fat-suppressed proton density-weighted MRI scan in 14-year-old female control participant shows a 4-mm DFCI (arrow) at the distal MHG attachment (*). (e, f) Sagittal fat-suppressed ...

For mean wall thickness measured with proton density-weighted MRI, the corresponding associations were 1.32, 1.48, and 1.37.

According to ARRS' American Journal of Roentgenology (AJR), ultrasound-derived fat fraction (UDFF) is strongly associated with MRI proton-density fat fraction (PDFF) and provides high sensitivity ...

Multi-sequence knee magnetic resonance imaging (MRI) is an advanced non-invasive diagnostic method for knee pathology. However, MRI interpretation is highly time-consuming and heavily dependent on ...

MRI of atherosclerosis has been validated as a reliable assessment of the size of the vessel lumen, but also the size of the plaque, its tissue composition and plaque activity, including inflammation.
