Abstract: Intra-Voxel Incoherent Motion (IVIM) is special Diffusion MR Imaging protocol that is acquired at multi bvalues using multiple diffusion

2016-02-10 · Background Intravoxel incoherent motion (IVIM) MR imaging has been applied in researches of various diseases, however its potential in cervical cancer patients has not been fully explored. The purpose of this study was to investigate the feasibility of IVIM MR imaging to monitor early treatment response in patients receiving concurrent chemo-radiotherapy (CCRT) for advanced cervical cancers

Intravoxel incoherent motion (IVIM) is a magnetic resonance imaging (MRI) technique that extracts microvascular perfusion information from a multi-b value diffusion-weighted imaging (DWI) sequence. 5,6 IVIM separates the incoherent blood motion in the capillary bed from the incoherent motion because of thermal motion within the DWI signal using a double exponential signal equation, 7,8 which

Methods. Intravoxel incoherent motion (IVIM), which was first described by Li Bihan et al. in 1986 , separates microcirculation perfusion and water molecule diffusion by using a biexponential model [22, 25, 26]. Using this biexponential model, DWI is able to use signal intensity produced by multiple b-values to analyze water/tissue diffusitvity. In general, only one diffusion model would be applied to whole field-of-view voxels in the intravoxel incoherent motion-magnetic resonance imaging (IVIM-MRI) study.
