Susceptibility Weighted Imaging (SWI) is a new T2* weighted Gradient Echo sequence that exploits the magnetic properties of tissues due to local inhomogeneities in the magnetic field. The essential feature in this technique is to tap the paramagnetic properties, specifically those of the deoxygenated hemoglobin, in order to make deoxygenated hemoglobin increasingly visible especially on the MRI phase images.

520 $a Susceptibility Weighted Imaging (SWI) is a new T2* weighted Gradient Echo sequence that exploits the magnetic properties of tissues due to local inhomogeneities in the magnetic field. The essential feature in this technique is to tap the paramagnetic properties, specifically those of the deoxygenated hemoglobin, in order to make deoxygenated hemoglobin increasingly visible especially on the MRI phase images.
520 $a The study also emphasizes the clinical potentials of this high resolution imaging technique, particularly in the case of Diffuse Axonal Injury (DAI) in Traumatic Brain Injury. SWI holds clinical significance in the above mentioned pathology because studies proved that hemorrhagic lesions visible in SWI are significantly higher than those detected by conventional imaging techniques. These findings are primarily because susceptibility weighted imaging is capable of detecting microhemorrhages which are undetected in the case of CT scans and other current MR imaging techniques. This could help in SWI contributing to effective and efficient evaluation of DAI, bringing about a correlation between prognosis and outcome. (Abstract shortened by UMI.)
