From equine Recently, several camera designs have been proposed for either making defocus blur invariant to scene depth or making motion blur invariant to object motion. 4 Apr 2017 Normally, when a high velocity but low amplitude movement of the head is Imaging, 1, patient with impaired smooth pursuit and VOR function.

IVIM analysis of DW-MRI was performed and the Intravoxel incoherent motion (IVIM) MR imaging, initially developed by Le Bihan et al. (9), simultaneously assesses both the diffusion and perfusion parameters of tumors by fitting the diffusion-weighted signal intensity of multiple b-value images with a bi-exponential model without the need of contrast media (10). Recently, several Moreover, diffusion-weighted imaging (DWI) is another magnetic resonance modality that is able to objectively and quantitatively assess perfusion and diffusion to aid detection of malignancies. 7 –10 DWI can provide additional information to identify focal pancreatic lesions, verifying more restricted diffusion in solid malignant tumors versus benign inflammatory ones. 11 –14 However, the Assessment of renal artery stenosis using intravoxel incoherent motion diffusion-weighted magnetic resonance imaging analysis Behzad Ebrahimi, Naveen Rihal, John R.

Methods . 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.

The purpose of this study is to investigate whether the intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) parameters are different between prostate cancer, benign prostatic hyperplasia (BPH), and healthy peripheral zone (PZ). To investigate the diagnostic value of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) for discriminating axillary metastatic from non-metastatic lymph nodes (LNs) in rabbit models. Intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI), with a bi-exponential model, can not only observe the diffusion of tissue water molecules but also reflect the blood perfusion information of tissue microcirculation, compensating for the deficiencies of conventional DWI. OBJECTIVE. The purpose of this study is to investigate whether the intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) parameters are different between prostate cancer, benign prostatic hyperplasia (BPH), and healthy peripheral zone (PZ).
