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.

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).
This shows enhancement on the coronal gadolinium-enhanced T1-weighted image (C).
Magnetic resonance imaging (MRI) yielded a low-intensity T1-weighted image and a high-intensity T2-weighted image, and no signs suggesting malignancy.
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.
Gadolinium-enhanced T1-weighted image revealed that the tumour was surrounded by an enhanced uniform thick capsule (Fig.
The masses are moderately enhancing on a postcontrast T1-weighted image.
A precontrast sagittal T1-weighted image showed a mass in the region of the pineal gland, with a thin rim of intrinsic signal hyperintensity and enlargement of the third and lateral ventricles (Figure 2).
On MRI, rice bodies have been described as having iso-or hypointense signal intensities relative to skeletal muscle on T1-and T2-weighted images, and the rice bodies were less discernible from the surrounding bursa fluid on T1-weighted image and clearly discernible on T2-weighted image.

In addition, an intra-articular gadolinium coronal T1-weighted image shows the gadolinium contrast extending superiorly into the tibiofibular joint recess.
After administration of contrast material, the cystic lining enhanced on the T1-weighted image.
If we want to acquire a fast, robust study with T1-weighted image contrast, one option is a fast spin-echo sequence, as used for T2-weighted imaging.
