Quantitative Susceptibility Mapping: Concepts and Applications
Splet21. feb. 2024 · The value of cerebral susceptibility-weighted imaging (SWI) in malignant melanoma (MM) patients remains controversial and the effect of melanin on SWI is not well understood. Purpose. To systematically analyze the spectrum of intracerebral findings in MM brain metastases (BM) on SWI and to determine the diagnostic value of SWI. Splet01. okt. 2024 · Susceptibility weighted imaging (SWI) is a 3D gradient-echo MR technique that is based on blood oxygen level dependent (BOLD) induced phase effects between the venous blood and the surrounding brain parenchyma. SpletSusceptibility Weighted Imaging (SWI)* We have developed a new type of contrast in MRI different from spin density, T1, or T2 imaging. This new method exploits the susceptibility differences between tissues. We refer to this method as Susceptibility Weighted Imaging*. picture of man falling down stairs
