T2 and proton density. MR scans that bring out T1 contrast are defined as T1-weighted. The primary basis for different types of contrast in MRI is the choice of two scan parameters: TR (repletion ...

The most common MRI sequences are T1-weighted and T2-weighted scans. T1-weighted images are produced by using short TE and TR times. The contrast and brightness of the image are predominately ...

Mid-Sagittal MRI of the Lumbar Spine. Left (T1-weighted image); Right (T2-weighted image). On this view centered over the lumbar spine, one can see all five lumbar vertebrae in addition to the sacrum ...

Prostate zonal anatomy is best demonstrated with MRI. On T2-weighted sequences ... for this reason it is important that a T1-weighted sequence is also performed to demonstrate high signal blood ...

Fig 2 (A) T1-weighted, (B) T2-weighted, (C) fluid-attenuated inversion recovery, (D) susceptibility-weighted, (E) m-ADC (mean apparent diffusion coefficient) map, and (F) postcontrast T1-weighted ...

The number of gadolinium-enhancing lesions per T1-weighted MRI scan, the annualized rate of lesions on T2-weighted MRI, and serum neurofilament light chain levels, but not the change in brain ...
