摘要
磁共振成像(MRI)是临床上不可或缺的诊断成像技术。与 X 射线和计算机断层扫描(CT)相比,磁共振成像的优势在于其对比度取决于不同器官组织的密度差异。除了医院的核磁共振成像系统外,日本还有 100 多套系统用于各领域的研究目的,包括基础科学研究、分子和临床研究以及生命科学研究,如药物开发、兽医和食品检测。多年来,在辐射技术、医学物理和放射学领域的基础研究中还开展了其他临床前成像研究。临床前核磁共振成像研究包括使用小孔和全身核磁共振成像系统进行的研究。在本综述中,我们重点讨论使用小口径磁共振成像系统进行的动物研究,即 "临床前磁共振成像"。临床前磁共振成像可用于阐明疾病的病理生理学和转化研究。本综述将概述以往的临床前磁共振成像研究,如大脑、心脏和肝脏疾病评估。此外,我们还将概述临床前磁共振成像研究在放射物理学和技术方面的用途。
Preclinical magnetic resonance imaging and spectroscopy in the fields of radiological technology, medical physics, and radiology.
Magnetic resonance imaging (MRI) is an indispensable diagnostic imaging technique used in the clinical setting. MRI is advantageous over X-ray and computed tomography (CT), because the contrast provided depends on differences in the density of various organ tissues. In addition to MRI systems in hospitals, more than 100 systems are used for research purposes in Japan in various fields, including basic scientific research, molecular and clinical investigations, and life science research, such as drug discovery, veterinary medicine, and food testing. For many years, additional preclinical imaging studies have been conducted in basic research in the fields of radiation technology, medical physics, and radiology. The preclinical MRI research includes studies using small-bore and whole-body MRI systems. In this review, we focus on the animal study using small-bore MRI systems as "preclinical MRI". The preclinical MRI can be used to elucidate the pathophysiology of diseases and for translational research. This review will provide an overview of previous preclinical MRI studies such as brain, heart, and liver disease assessments. Also, we provide an overview of the utility of preclinical MRI studies in radiological physics and technology.
期刊介绍:
The purpose of the journal Radiological Physics and Technology is to provide a forum for sharing new knowledge related to research and development in radiological science and technology, including medical physics and radiological technology in diagnostic radiology, nuclear medicine, and radiation therapy among many other radiological disciplines, as well as to contribute to progress and improvement in medical practice and patient health care.
