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.

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].

Caption: Figure 11: A 35-year-old male with fat-saturated T1-weighted image showing a lesion abutting the right atrium that is isointense to the surrounding muscle.
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 extradural herniated disc fragment appears hypo to isointense on the T1-weighted image and hyperintense on T2 images, which was similar to our case.
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).
Using lesion size measured on contrast-enhanced T1-weighted image as the reference, we calculated and compared area ratio of T1 ([AR.
Sacral magnetic resonance imaging (MRI) obtained by the previous doctor showed a low-intensity T1-weighted image of the left second sacral ala and a high-intensity T2-weighted image and a short TI inversion recovery (STIR) image (bone marrow edema) compared with the right side.
At ten months after initiation of the treatment, short-inversion-time inversion-recovery (STIR) showed no edematous lesions and no joint effusion; however, T1-weighted image showed low signal osteoarthritis change.
Gadolinium-enhanced T1-weighted image revealed that the tumour was surrounded by an enhanced uniform thick capsule (Fig.
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.
Magnetic resonance imaging (MRI) is a useful tool for the definitive diagnosis of SIF, which is seen as a low intensity band surrounded by bone marrow edema on the T1-weighted image [1, 3].
