Comparative StudyQuantitative vs. semiquantitative assessment of intratumoral susceptibility signals in patients with different grades of glioma.
Susceptibility weighted imaging (SWI) provides vascular information and plays an important role in improving the diagnostic accuracy of preoperative glioma grading. Intratumoral susceptibility signal intensities (ITSS) obtained from SWI has been used in glioma grading. However, the current method for estimation of ITSS is semiquantitative, manual count-dependent, and includes hemorrhage as well as vasculature. ⋯ 4 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2020;51:225-233.
