What Is an MRI With Contrast? MRI With the advancements in medical imaging technology and a higher prevalence worldwide, you might have become more familiar with one type of imaging technology known as magnetic resonance imaging (MRI) ― and the value it offers to health care. You might be...
In magnetic resonance imaging (MRI), contrast agents are used to enhance the imaging of tissue structures. While they enhance signals in blood vessels and in spaces between cells, they do not reach the interior of the cell. By contrast, glucose is taken up and then broken down in the body...
A novel MRI contrast technique enables to observe tissue properties not observable by previously known MRI methods. A difference between two disclosed pulse sequences is used to measure magnetization exchange time between water molecules and macromolecules such as proteins, thereby producing a measure ...
Most MRIs are performed without a contrast dye because it isn't needed to get accurate results for the suspected problem. Also, certain patients (those who are pregnant as well as those with kidney disease) shouldn't get the contrast dye because of possible complications. What Is an MRI Scan...

摘要: This chapter covers all current types of contrast agents (CA) for use in Magnetic Resonance Imaging (MRI). It is intended for learning rather than exhaustive review, presenting and discussing terms...DOI: 10.1007/978-3-642-60061-6_1 ...
The results are often good, although some patients develop prolonged morbidity with postoperative pain and stiffness. The main aim of the present study was to analyze the reaction of the joint capsule 3 months after subacromial decompression using MRI without contrast. We also wanted to study if ...
对比分辨率(Contrast Resolution):在影像中区分两种不同物质的能力。 平行成像(Parallel Imaging):利用多个接收线圈同时接收信号的成像技术。 干扰(Interference):来自外部源的不需要的信号。 异相(Out-of-phase):描述MRI图像中两个或更多信号不同时达到最大值的现象。
