T1WI

in subacute and chronic brain hemorrhage there was a high signal on T1WI , a characteristic could be clearly diagnosed.

MRI shows a heterogeneous suprasellar mass with low signal intensity relative to gray matter on T1WI and FLAIR.

MRI scan suggested uniform T1WI signal, and slight increase in T2WI signal, and enhanced scan suggested even enhancement.

The coronal T1WI image was superior to coronal T2WI and gradient echo images in demonstrating the mandibular nerve.

There were a low signal septum between spinal cord and hematoma on T1WI and T2WI.

Methods: Models of cartilage injuries were established in 25 cattle knees, with SPIR-3D-FFE-T1WI sequence in the detection of knee injuries.

In 4 cases with lipoma of filum terminale, on T1WI filum terminal had nodular or stringed lipoma signal.

In 1 case with spinal meningeal cyst, ovoid cyst with low signal on T1WI and high signal on T2WI in the sacral canal.

Results The muscles and fat in nasopharyngeal masticator space of 40 cases (80 sides) were well demonstrated on both T1WI and T2WI images.

In 4 cases with intradural lipoma, subdural lesion with high signal on T1WI and T2WI.

T1WI images showed low signal in 3 cases and equal signal in 14 cases.

bilateral tentorial can better in T1WI and T2WI showed symmetric low signal;
