MRI Imaging Methods and Common Disease Abbreviations

MRI Imaging Methods The MRI image is formed by reconstructing signals generated from the resonance of hydrogen nuclei in a magnetic field. Therefore, the concept used in MRI images is “signal,” rather than the “density” concept used in CT images. In MRI images, lesions are described using the term “abnormal signal focus.” Because the imaging … Read more

by
Principles and Clinical Applications of Diffusion Weighted Imaging (DWI and ADC)

What is Functional Magnetic Resonance Imaging? Various magnetic resonance imaging techniques based primarily on conventional T1WI and T2WI mainly display the morphological structures of human organs or tissues and their signal intensity changes, collectively referred to as conventional MRI examinations or conventional MR imaging sequences. With the development of MRI system hardware and software, various … Read more

High-Q Metasurface Signal Isolator for Portable MRI Devices

“The combination of surface coils and metamaterials significantly improves the performance of Magnetic Resonance Imaging (MRI), offering notable local enhancement flexibility. However, due to the coupling between the two, the signal-to-noise ratio (SNR) and low contrast resolution are hindered, further obstructing the future development of clinical MRI. This paper proposes a high-Q metasurface decoupling isolator, … Read more
