T1 weighted image

T1 weighted image

MRI made with pulse spin echo or inversion recovery sequence with short TR and TE to show contrast between tissues with different T1 values; an image with greater signal intensity from fat-containing tissues.

This becomes clear in the T1 weighted image (Figure 4), where the epineurial fat is hyperintense and the fascicles are hypointense.
There is low signal in the medullary component in T1 weighted image. T2 weighted image shows both hypointense and isointense signal in the medullary component of the medial end of the left clavicle.
In T2 weighted and FLAIR images, the cyst was hyperintense in all the 3 patients (Fig 1b, 1c, 2b, 2c, 3b, 3c); whereas in T1 weighted image, the cyst was isointense with muscles in two patients (Fig 1a, 2a) and hypointense in 1 patient (Fig 3a).
Standard T1 weighted images with fat saturated T1 weighted images establish the diagnosis when the fat removed and the fluid-fat levels is also seen.
* The lesion was mildly hyperintense on T1 weighted images; on T2 weighted images it was isointense and showed mild restriction on diffusion weighted images.
In magnetic resonance (MR) imaging, white matter hypointensities in T1 weighted images, and white matter hyperintensities in T2 weighted and FLAIR images are regarded as visualizations of WML.

Maximum aortic diameter was automatically obtained from manual tracing on T1 weighted images in all examinations.
At MRI they are isointense relative to the myocardium on T1 weighted images and isointense-heterogeneously hyperintense on T2-weighted images; they demonstrate heterogeneous enhancement after administration of gadolinium contrast material (5).
