MEM Introduction Ulnar-sided wrist pain is common among athletes, and the usual causes include independent or combined injuries to the triangular fibrocartilage complex (TFCC), the extensor carpi ulnaris (ECU), and the distal radioulnar joint (DRUJ). Sports that require repeated forearm pronation/supination, radial/ulnar deviation, and axial loading can easily lead to ulnar-sided wrist pain in athletes. … Read more

Additionally, there are two Philips flat-panel digital subtraction angiography (DSA) machines (one yet to be installed), one … Read more
1.High-frequency mobile C-arm, widely applicable in clinical settings: can be used for interventional imaging/bone surgery/gastroenterology intervention/vascular intervention/neurosurgery intervention/tumor intervention/pain intervention. 2.B ultrasound is a technology that uses ultrasound to detect the human body, constructing organ images based on the feedback from sound waves. 3.CT (Computed Tomography) is a type of electronic computer tomography that uses … Read more
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
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

Robert G. Briggs and colleagues from the Department of Neurosurgery at the University of Southern California in Los Angeles studied the Superior Frontal Gyrus (SFG) and its white matter connections through MRI imaging of brain fiber bundles in healthy adults and anatomical studies of cadaver brains. Their results were published online in the journal Clin … Read more
DTI imaging has a relatively long application history, as it can display the overall orientation of fiber bundles and generate quantitative parameters such as FA values and MD values to reflect microstructural information. However, studies have shown that this model has limitations in displaying complex fiber bundle orientations, especially for crossing fibers and fibers with … Read more
