T1-weighted image

T1-weighted image

An MRI term for an image created using short echo times (TE) and repetition times (TR), the contrast and brightness of which are largely determined by T1 signals.

On MR, SFT usually presents with intermediate intensity on T1-weighted image and heterogenous hypointense on T2-weighted image, which is related to hypercellularity or collagen.
B) Axial gadolinium-enhanced T1-weighted image shows enhancement within the cisternal segment of both the vestibulocochlear nerve complex and the facial nerve.

Abdominal magnetic resonance imaging (MRI) showed that the lesion is slightly hypointense on T1-weighted image with the central scar appears more significant hypointense (Figure 3(a)) and slightly hyperintense on T2-weighted images (Figure 3(b)).

Capsular wall and internal septae of the lesion are isointense on T1-weighted image and hypointense on T2-weighted image; marginally contrast enhancement seen on fat-saturated contrast enhanced T1-weighted image (c).
The lesion was isointense relative to muscle on the T1-weighted image and hyperin tense on the T2-weighted image with a swirled appearance [Figure 1].

There was also an axial-coronal T1-weighted image with contrast showing enhancement of a nodular hyperintense active MS plaque in the left posterior limb of the internal capsule (Figure 2).
The selected images are images where the examination occurs during the relaxation took place, such as T1-weighted image and T2-weighted image (Figure 2).
On the T1-weighted image, the mass was of similar signal intensity to the adjacent muscles with an area of decreased signal intensity centrally and an area of slightly increased signal intensity peripherally.
