Book excerpt: Magnetic Resonance Imaging“Magnetic Resonance Imaging” (MRI) is the most widely clinically used diagnostic tool for soft tissue imaging. This advanced technology and its applications are under continuous research and development, ranging from lower fields to ultra-high fields to the highest possible fields for preclinical (animal) and human imaging. Formerly known as Nuclear Magnetic Resonance Imaging (NMR), with the rising demands of clinical diagnosis requirements, it is under constant development and innovation in hospitals for populations around the world because of constant desire to go to higher fields that lead to unique research and clinical applications that aren’t achievable with other commercially and or research technologies. The basics of MRIThe human body is rich in hydrogen, when a human body is subjected to a large magnetic field, many of the free hydrogen nuclei align themselves with the direction of the magnetic field. MRI works on the principle of the directional magnetic field associated with charged particles in motion. MRI is also known as nuclear magnetic resonance imaging, a technique used to create images of parts of the human body based on the resonance of nuclei in motion under the effect of a magnetic field.

Book excerpt: Magnetic resonance imaging (MRI) may be used to provide detailed images of the human body with excellent soft tissue contrast. Alongside its current widespread clinical applications for diagnosis and treatment, MRI allows researchers to measure structure and function of different tissue types in order to advance our understanding of human biology and enable new medical applications of MRI. In particular, diseases affecting nerves and vessels, such as trigeminal neuralgia, with uncertain etiology can be studied using multiple MRI modalities so that treatment planning can we more effective and patient outcomes can be improved. Ultrahigh field MRI scanners, such as those operating at 7-‐tesla (7T), provide increased signal-‐to-‐noise ratio, which can be translated to higher spatial resolution. Additional advantages of high magnetic field MRI include enhanced vascular contrast as well as improved spectral separation and quantification for MR spectroscopy. These benefits over MRI at lower field strengths make ultrahigh field MRI a powerful new tool for performing quantitative image analysis with increased accuracy. One quantitative application of MRI is the detection and visualization of cells labeled with magnetic nanoparticles. This unconventional use of the imaging modality enables very effective imaging of cells or lesions tagged with these particles. The projects explored herein consist of such quantitative image analysis using advanced imaging techniques, including ultrahigh field MRI.

Download or read book Multi Dimensional Quantitative Dynamic Contrast Enhanced Magnetic Resonance Imaging Using Multitasking Technical Development and Applications written by Nan Wang and published by . This book was released on 2020 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic contrast enhanced (DCE) MRI plays a central role in the diagnosis, characterization, and treatment monitoring of various diseases. It can provide essential functional information of the tissues, including the perfusion and permeability properties. Besides, the changes in functional properties is recognized to precede the morphological alterations, which can potentially provide an avenue for early diagnosis and treatment evaluation. However, current practice of DCE MRI continues to face demanding technical challenges. First, there is direct conflict in the requirements for adequate anatomical coverage and high spatial and temporal resolution for tissues characterization. Existing techniques usually compromise one or more aspects, leading to suboptimal protocol. Second, dynamic T1 mapping for the quantification of CA concentration is hard to realize. Approximation in this step can introduce error in the derivation of DCE parameters. Third, imaging of some organs, such as heart or abdominal organs, is subject to artifacts caused by physiological motion, which can significantly degrade image quality or increase the scan time. Forth, the growing concern towards Gd deposition within body parts makes it controversial to use contrast agent. The primary goal of the work in the dissertation is to address the aforementioned limitations by developing a novel quantitative DCE MRI technique using MR Multitasking framework to achieve: 1) motion-resolved imaging with free-breathing acquisition and bulk-motion correction, 2) high spatial-temporal resolution with 3D anatomical coverage for simultaneous perfusion and permeability quantification, 3) dynamic T1 mapping for accurate quantification of CA concentration and potentials for reducing GBCA dose. All the technical advancements aims to improve the detection, staging, characterization, and treatment monitoring for multiple organs and diseases. There are three specific aims to achieve the ultimate goal. First, the Multitasking DCE technique was developed and tested in the study of carotid atherosclerosis. It enables 3D coverage of entire carotid vasculature with high spatial resolution (0.7 mm isotropic), high temporal resolution (600 ms), and dynamic T1 mapping for direct quantification of CA concentration. Bulk motion detection and removal scheme were also implemented for the improvement of image quality. In vivo studies have shown that the proposed technique can achieve accurate T1 quantification and robustness to motion. The PK parameters were repeatable in vivo and showed significant difference between carotid atherosclerosis and normal carotid vessel wall. Second, 6-dimensional (6D) Multitasking DCE technique was developed for the characterization of PDAC. It achieves respiratory-motion-resolved, high-temporal-resolution T1 quantification of the entire abdomen in a 10-min free-breathing scan. Sixteen healthy volunteers and 14 patients with pathologically confirmed PDAC were recruited for the in vivo study. The results demonstrated that the quantitative PK parameters using Multitasking DCE were repeatable in vivo and showed significant differences between normal pancreas, tumor and non-tumoral regions in PDAC patients. In addition, 8 patients with confirmed CP were recruited. The PK parameters representing blood flow and vascular properties showed significant difference between normal pancreas, PDAC, and CP. Third, the Multitasking DCE technique using a low dose at 0.02 mmol/kg (LD-MT-DCE) was developed for breast imaging. It produced co-registered high-spatial-resolution (0.9 mm 0.9 mm 1.14 mm) dynamic T1 maps at 1.4-second temporal resolution with whole-breast coverage in the 10-min scan. The dose was chosen to be 0.02 mmol/kg, 20% of the standard dose, based on a numerical simulation conducted to evaluate the dose effect on the accuracy and precision of the PK parameters quantified using LD-MT-DCE. Twenty healthy volunteers and 7 patients with breast cancer were recruited for the in vivo study. The results demonstrated that LD-MT-DCE were repeatable, showed excellent image quality and equivalent diagnosis compared with standard-dose clinical DCE. The estimated PK parameters were capable of differentiating between normal breast tissue, and benign and malignant tumors.
