Improving SWI Contrast
نویسنده
چکیده
Fig 2: A selected slice showing the SWI (A,B) and MIP (C, D) images with FH and FZ filters (α = 3, β = -0.1). Compared to FH (left), the FZ (right) showed clear improvement in the tissue contrast, both between gray and white matter tissue (B vs. A) and between veins and surrounding tissues (D vs. C). Fig 3: Determination of the optimal parameters α and β for FZ, using CoM. The optimal α is 2 to 4 with β around -0.1 and a contrast enhancement over 50% compared to FH. A B

Susceptibility-weighted imaging (SWI) has continued to develop into a powerful clinical tool to visualize venous structures and iron in the brain and to study diverse pathologic conditions. It is a new art which evaluates and exploits the properties of blood, iron and other tissues. It is a magnitude or filtered phase images or combination of both, obtained with high-resolution 3D fully velocit...
متن کاملImproving Signal-to-Noise Ratio in Susceptibility Weighted Imaging: A Novel Multicomponent Non-Local Approach
In susceptibility-weighted imaging (SWI), the high resolution required to obtain a proper contrast generation leads to a reduced signal-to-noise ratio (SNR). The application of a denoising filter to produce images with higher SNR and still preserve small structures from excessive blurring is therefore extremely desirable. However, as the distributions of magnitude and phase noise may introduce ...
