Intravoxel incoherent motion (IVIM) imaging in human achilles tendon
Journal of Magnetic Resonance Imaging, 2018BackgroundLimited 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 (IVIM) 3 T MRI for orbital lesion characterization
European Radiology, 2020To determine the diagnostic accuracy of MRI intravoxel incoherent motion (IVIM) when characterizing orbital lesions, which is challenging due to a wide range of locations and histologic types.This IRB-approved prospective single-center study enrolled participants presenting with an orbital lesion undergoing a 3-T MRI prior to surgery from December 2015

Intravoxel incoherent motion (IVIM) imaging at different magnetic field strengths: What is feasible?
Magnetic Resonance Imaging, 2014Due to limited SNR the cerebral applications of the intravoxel incoherent motion (IVIM) concept have been sparse. MRI hardware developments have resulted in improved SNR and this may justify a reassessment of IVIM imaging for non-invasive quantification of the cerebral blood volume (CBV) as a first step toward determining the optimal field strength.To ...

Intravoxel Incoherent Motion (IVIM) to study synovitis in Osteoarthritis: a feasibility study
ISMRM Annual Meeting, 2023Synovial inflammation (synovitis) is present in the majority of people with Osteoarthritis(OA) and has been linked with pain, disease severity and progression of knee OA. However, synovitis is not widely studied due to challenges differentiating synovial inflammation from adjacent fluid on conventional MRI and contraindications and time, cost and ...

Intravoxel Incoherent Motion (IVIM) MRI in Intracranial, Extraaxial Tumors and Cysts
Journal of Computer Assisted Tomography, 1992Intravoxel incoherent motion MRI was used to assess six intracranial, extraaxial cysts and tumors including two epidermoids, two cystic acoustic schwannomas, and two arachnoid cysts. A maximum gradient strength of 0.7 g/cm was used simultaneously along all axes (maximum gradient beta value: 445 s/mm2) and comparisons were made with an external water ...

Measuring brain perfusion with intravoxel incoherent motion (IVIM): Initial clinical experience
Journal of Magnetic Resonance Imaging, 2013PurposeTo evaluate the feasibility of intravoxel incoherent motion (IVIM) perfusion measurements in the brain with currently available imaging systems.Materials and MethodsWe acquired high in‐plane resolution (1.2 × 1.2 mm2) diffusion‐weighted images with 16 different values of b ranging from 0 to 900 s/mm2, in three orthogonal directions, on 3T ...

Huntington’s disease (HD) is a neurodegenerative movement disorder that negatively impacts quality of life. Atypical antipsychotics are used for treatment, though with limited evidence from controlled trials. In this preliminary study we investigated the effects of risperidone, an atypical antipsychotic for the treatment of chorea in HD using

Mapping the intra-tumoral heterogeneity of perfusion before and after treatment offers the opportunity to identify hypoxic regions in the tumour and predict recurrent disease. Intravoxel Incoherent Motion (IVIM) parametric maps were obtained in patients with prostate cancer before and after radiation therapy.

Does intravoxel incoherent motion (IVIM) introduce a new biomarker in MRI?
Physica Medica, 2016Introduction Intravoxel Incoherent Motion (IVIM) imaging is a method that provides quantitative assessment all of the microscopic translational motions that could contribute to the signal acquired with diffusion weighted imaging (DWI) in MRI. The fundamental idea was that the molecular motion of water is randomly oriented in the capillary network at ...
