Quantitative MRI Uncovers Subtle Cortical Damage in Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease. [PDF]

Ann Clin Transl Neurol
ABSTRACT Objective To determine whether myelin‐sensitive quantitative MRI reveals microstructural abnormalities in normal‐appearing cortex (NACtx) in myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), indicating that conventional MRI underestimates remission residual cortical injury.

Quantitative cardiac MRI [PDF]

Journal of Magnetic Resonance Imaging, 2019
Cardiac MRI has become an indispensable imaging modality in the investigation of patients with suspected heart disease. It has emerged as the gold standard test for cardiac function, volumes, and mass and allows noninvasive tissue characterization and the assessment of myocardial perfusion. Quantitative MRI already has a key role in the development and

Quantitative pharmacologic MRI in mice [PDF]

NMR in Biomedicine, 2011
Pharmacologic MRI (phMRI) uses functional MRI techniques to provide a noninvasive in vivo measurement of the hemodynamic effects of drugs. The cerebral blood volume change (ΔCBV) serves as a surrogate for neuronal activity via neurovascular coupling mechanisms.

Quantitative MRI assessment of leukoencephalopathy [PDF]

Magnetic Resonance in Medicine, 2002
AbstractQuantitative MRI assessment of leukoencephalopathy is difficult because the MRI properties of leukoencephalopathy significantly overlap those of normal tissue. This report describes the use of an automated procedure for longitudinal measurement of tissue volume and relaxation times to quantify leukoencephalopathy.

Quantitative Brain MRI [PDF]

Topics in Magnetic Resonance Imaging, 2010
This issue of Topics in Magnetic Resonance Imaging (MRI) is about “Quantitative Brain MRI.” What do we mean by “quantitative” MRI? In the context of imaging studies, the term quantitative is often used when numeric values of signal intensities are measured in addition to performing the conventional “qualitative” visual inspection of the images.

Quantitative measurement of hopper flow using MRI [PDF]

EPJ Web of Conferences, 2021
To gain fundamental insight into granular flow behaviour, quantitative measurements of velocity and solid fraction are required. The aim of this study is to measure the solid fraction and velocity of 3D granular flows quantitively using a recently ...

Variability and reproducibility of multi-echo T2 relaxometry: Insights from multi-site, multi-session and multi-subject MRI acquisitions

Frontiers in Radiology, 2022
Quantitative magnetic resonance imaging (qMRI) can increase the specificity and sensitivity of conventional weighted MRI to underlying pathology by comparing meaningful physical or chemical parameters, measured in physical units, with normative values ...

Revisiting brain iron deficiency in restless legs syndrome using magnetic resonance imaging

NeuroImage: Clinical, 2022
Study objectives: Studies on brain iron content in restless legs syndrome (RLS) using magnetic resonance imaging (MRI) are heterogeneous. In this study, we sought to leverage the availability of a large dataset including a range of iron-sensitive MRI ...

Quantitative Diffusion-Weighted MRI of Neuroblastoma

Cancers, 2023
Neuroblastoma is the most common extracranial, malignant, solid tumor found in children. In more than one-third of cases, the tumor is in an advanced stage, with limited resectability. The treatment options include resection, with or without (neo-/) adjuvant therapy, and conservative therapy, the latter even with curative intent.
