Quantitative sodium MRI of kidney

NMR in Biomedicine, 2015
One of the main tasks of the human kidneys is to maintain the homeostasis of the body's fluid and electrolyte balance by filtration of the plasma and excretion of the end products. Herein, the regulation of extracellular sodium in the kidney is of particular importance.

Quantitative MRI of the Prostate and Uterus in Monkeys

Magnetic Resonance in Medicine, 1992
AbstractQuantitative MRI has been carried out in the prostate, seminal vesicles, uterus, and ovaries in the pig‐tailed monkey, Macaca nemestrina. T2‐weighted, fat‐suppressed, multislice experiments were performed at 2.35 T. Eight males, 14 ovariectomized females, and 20 intact females were studied.

Quantitative diffusion MRI of the abdomen and pelvis

Medical Physics, 2021
AbstractDiffusion MRI has enormous potential and utility in the evaluation of various abdominal and pelvic disease processes including cancer and noncancer imaging of the liver, prostate, and other organs. Quantitative diffusion MRI is based on acquisitions with multiple diffusion encodings followed by quantitative mapping of diffusion parameters that ...

Quantitative MRI Musculoskeletal Techniques: An Update [PDF]

American Journal of Roentgenology, 2019
OBJECTIVE. For many years, MRI of the musculoskeletal system has relied mostly on conventional sequences with qualitative analysis. More recently, using quantitative MRI applications to complement qualitative imaging has gained increasing interest in the MRI community, providing more detailed physiologic or anatomic information. CONCLUSION.

MRI protocol optimization for quantitative DCE-MRI of the spine

Magnetic Resonance Imaging, 2017
In this study we systematically investigated different Dynamic Contrast Enhancement (DCE)-MRI protocols in the spine, with the goal of finding an optimal protocol that provides data suitable for quantitative pharmacokinetic modelling (PKM).In 13 patients referred for MRI of the spine, DCE-MRI of the spine was performed with 2D and 3D MRI protocols on a

Towards quantitative MRI for the clinic

Physica Medica
Magnetic Resonance (MR) is an effective tool for clinical diagnosis, staging, monitoring, treatment planning, and assessing response to therapy. Measurements of anatomical, physiological, and biochemical characteristics of the organs through MR, referred to as quantitative imaging, is becoming increasingly used in clinical research for drug and medical

Methods and Applications of Quantitative MRI

2005
The general objective of quantitative magnetic resonance imaging (MRI), or parametric mapping, consists of reconstructing synthetic images in which each voxel bears the value of a physical parameter selected a priori. Due to the large degrees of freedom in the choice of acquisition parameters, MRI is versatile and is thus able to quantify different ...

Quantitative MRI Assessment of Alzheimer's Disease

Journal of Molecular Neuroscience, 2004
The development of a noninvasive method to detect early, subtle changes in the brains of patients with Alzheimer's disease (AD) would have considerable clinical value as therapy. This therapy is most likely to be successful if intervention could occur before neurons were irreversibly damaged or lost.

A quantitative MRI study of vascular dementia

Neurology, 1992
We studied the MRI and clinical factors associated with dementia following stroke by quantifying ventricle-to-brain ratio (VBR), anatomic region of infarction, and cortical, subcortical, and white matter areas of infarction in 24 stroke patients with dementia and 29 nondemented stroke patients.

An MRI phantom material for quantitative relaxometry

Magnetic Resonance in Medicine, 1987
AbstractMost phantom media in current use exhibit T1 relaxation times that are significantly dependent on both temperature and operating frequency. This can introduce undesirable variability into relaxation measurements due to temperature fluctuations, and complicates direct comparison of imagers operating at different magnetic field strengths.
