- strongly T2 weighted GRE sequence → combination of high signal levels and extremely high spatial resolution (excellent tissue/fluid contrast); flow-compensated, 2- or 3-dimensional gradient echo acquisition to obtain images with contrast that is proportional to the ratio of T2 relation time to T1 relaxation time → high signal-to-noise and ...

A, B. T2WI and FLAIR image shows hyperintense lesions in the pons, and inferior cerebellar peduncles (red arrows), and in the callosomarginal interface in the deep white matter, which is characteristic of MS. C, D. Hyperintense lesions are also seen in the midbrain, and the superior cerebellar peduncle (red arrows). Figure 16.

This information is useful in cases of lesion with T2 hyperintense signal, which can misleadingly produce high signal on the DWI trace maps which are also T2 weighted (i.e. ADC helps in differentiation between T2-shine-through and diffusion restriction).

MRI: Pseudocystic multinodular, hypointense on T1, hyperintense on T2, no peritumoural oedema. May have mixed signal with bright rim on FLAIR. Pleomorphic xantoastrocytoma: WHO grade 2. Temporal lobe most common location. Usually benign, found almost exclusively in young adults, often long-standing temporal lobe epilepsy.

FLAIR images are T2-weighted with the CSF signal suppressed. When reviewing an MR image, the easiest way to determine which pulse sequence was used, or the "weighting" of the image, is to look at the cerebro-spinal fluid (CSF). If the CSF is bright (high signal), then it must be a T2-weighted imaged. If the CSF is dark, it is a T1-weighted image.
