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. ... observing a ...

The researchers performed one scan during proton irradiation, and three immediately after irradiation, using a variety of MR sequences. For two of the six MR sequences – the proton density-weighted ...

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 ...

(e, f) Sagittal fat-suppressed proton density-weighted MRI scans in 15-year-old female control participant (e) and 15-year-old male control participant (f) without a DFCI for comparison.

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

MRI examinations included three PDFF acquisitions with calculation of an overall median PDFF. Ultimately, UDFF was positively associated with MRI PDFF (rho=0.82 [95% 0.71-0.89]; p<.001), with mean ...

Multi-sequence knee magnetic resonance imaging ... (T2W), and proton density-weighted (PDW) MRI sequences from sagittal, coronal, and axial planes. By combining data from arthroscopy, ...

The primary endpoints were volume of abnormal signal on MRI (group 1) and correlation between APT-weighted % hyperintensity and pathology (group 2). Results: Nine patients were studied in group 1.
