Intravoxel Incoherent Motion Imaging

2021
Intravoxel incoherent motion (IVIM) refers to the microscopic incoherent motion of water molecules within each imaging voxel, which includes true diffusion and pseudo-diffusion caused by capillary perfusion. By applying a bi-exponential model to diffusion-weighted images obtained with multiple b values, IVIM imaging noninvasively simultaneously ...

Intravoxel incoherent motion imaging of focal hepatic lesions

Journal of Magnetic Resonance Imaging, 2012
AbstractPurpose:To compare diffusivity values between malignant and benign focal hepatic lesions using the intravoxel incoherent motion model.Materials and Methods:This study included 84 focal hepatic lesions in 84 patients. Final diagnoses were as follows: hepatocellular carcinoma (n = 45), cholangiocarcinoma (n = 6), metastatic liver tumor (n = 3 ...

Flow‐compensated intravoxel incoherent motion diffusion imaging

Magnetic Resonance in Medicine, 2014
PurposeThe pseudo‐diffusion coefficient D* in intravoxel incoherent motion (IVIM) imaging was found difficult to seize. Flow‐compensated diffusion gradients were used to test the validity of the commonly assumed biexponential limit and to determine not only D*, but also characteristic timescale τ and velocity v of the incoherent motion.Theory and ...

Intravoxel incoherent motion (IVIM) imaging in human achilles tendon

Journal of Magnetic Resonance Imaging, 2018
BackgroundLimited microcirculation has been implicated in Achilles tendinopathy and may affect healing and disease progression. Existing invasive and noninvasive approaches to evaluate tendon microcirculation lack sensitivity and spatial coverage.PurposeTo develop a novel Achilles tendon intravoxel incoherent motion (IVIM) MRI protocol to overcome the ...

Intravoxel incoherent motion diffusion-weighted imaging in the characterization of Alzheimer’s disease

Brain Imaging and Behavior, 2021
Alzheimer's disease (AD) is the most common type of dementia, and characterizing brain changes in AD is important for clinical diagnosis and prognosis. This study was designed to evaluate the classification performance of intravoxel incoherent motion (IVIM) diffusion-weighted imaging in differentiating between AD patients and normal control (NC ...
