Optimal Low B-value in Intravoxel Incoherent Motion Diffusion

Intravoxel incoherent motion imaging (IVIM) is a new magnetic resonance imaging (MRI) technique that can detect both diffusion and pseudo perfusion microscopic tissue information. Intravoxel incoherent motion (IVIM) imaging wasintroduced to assessbothtumor diffusion and perfusion noninvasively by analyzing the signal decay curve obtained from multiple b-value diffusion-weighted imaging (DWI) acquisition to separate the signal intensity arising from a vascular component and that from a nonvascular component [8]. ST REPORTS 163 DOI 1.13srep163 1 www.nature.comscientificreports Intravoxel Incoherent Motion Diffusion-weighted Magnetic Resonance Imaging for Monitoring the Early Response to ZD6474 Eighteen healthy volunteers underwent intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI) scan of the liver twice in 1.5T MR scanner with signed informed consent approved by local ethic committees.

Intravoxel incoherent motion diffusion-weighted imaging for discriminating the pathological response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer 2017-10-01 · Intravoxel incoherent motion diffusion-weighted imaging analysis of diffusion and microperfusion in grading gliomas and comparison with arterial spin labeling for evaluation of tumor perfusion J Magn Reson Imaging , 44 ( 2016 ) , pp. 620 - 632 PURPOSE: To investigate the potential of Intravoxel incoherent motion diffusion-weighted imaging(IVIM-DWI) for the assessment of renal fibrosis in chronic kidney disease (CKD), using histopathology as a reference standard. METHODS: Eighty-five CKD patients and twenty healthy volunteers were recruited in this study. Intravoxel incoherent motion diffusion-weighted imaging analysis of diffusion and microperfusion in grading gliomas and comparison with arterial spin labeling for evaluation of tumor perfusion.

Both single-shot TSE-DWI and single-shot EPI-DWI were scanned twice respectively for 15 patients with lung cancer. In this review, we discuss the principles of intravoxel incoherent motion as applied to body diffusion-weighted MRI. The evidence for the technique in measuring tissue perfusion is presented and the emerging clinical utility surveyed. The requisites and challenges of quantitative evaluation beyond simple monoexponential relationships are highlighted. Intravoxel incoherent motion (IVIM) diffusion-weighted imaging was performed using 12 b values: 0, 10, 20, 30, 40, 50, 80, 100, 200, 400, 800, and 1000 sec/mm2.
