While a comprehensive review of MRI physics is beyond the scope of this article, a brief overview of MRI sequence parameters that drive T2-weighting is merited. TR (repetition time) reflects the time interval between initiating RF excitation pulses; TE (echo time) measures the time between the initial radiofrequency … WebScreening for these involves review of both T2-weighted and non-T2-weighted sequences.

WebT2 is generally the more commonly used, but T1 can be used as a reference for anatomical structures or to distinguish between fat vs. water bright signals. Additional features of … WebHyperintense intramedullary signal at T2-weighted imaging is a common and important indicator of myelopathy at MRI ( 1 ). T2 hyperintensity can reflect many processes at the microscopic level, including edema, blood–spinal cord barrier breakdown, ischemia, myelomalacia, or cavitation ( 2 ). WebJun 23, 2015 · For example, it was common to use T1-weighted (T1) or T2 sequences, T1 being of similar sensitivity to subcortical changes as is modern CT scanning, while T2 is relatively insensitive to subtle white matter abnormalities and is less good at identifying changes adjacent to a cerebrospinal fluid (CSF)-containing space than is FLAIR (eg, in the ... how big should a door be
