The strength of a magnet in an MRI system is rated using a unit of measure known as a tesla. Another unit of measure commonly used with magnets is the gauss (1 tesla = 10,000 gauss). The magnets in use today in MRI systems create a magnetic field of 1.5-tesla to 7.0-tesla, or ...

Tell your doctor if you have an MRI (magnetic resonance imaging) or any type of scan using a radioactive dye that is injected into a vein. Contrast dyes and furosemide can harm your kidneys. Furosemide on-body infusor (Furoscix) may be used to treat congestion due to fluid overload in ...
It's much easier and safer to look at a broken bone using X-rays than it is to open a patient up. But X-rays can also be harmful. In the early days of X-ray science, a lot of doctors would expose patients and themselves to the beams for long periods of time. Eventually, ...
Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body. Arthroscopy is a procedure to look inside your joint with a scope. The scope is a long tube with a magnifying glass, a camera, and ...
Treatment with cabergoline had significantly reduced the prolactin levels and had also improved the patient's headaches. High-resolution CT, with and without contrast, or MRI is necessary to visualise microprolactinomas (and other sellar lesions) and confirm the diagnosis. 展开 ...
Ultimately, the image produced by the MRI is a thin slice through the knee in one of these three planes. As an example, shown here is an overview of the knee on an axial PD image on a slice through the femoral condyles. In this modality, fat and hyaline cartilage show as white, ...
Since living in cities is associated with an increased risk for mental disorders such as anxiety disorders, depression, and schizophrenia, it is essential to understand how exposure to urban and natural environments affects mental health and the brain. I
Fröhlich interaction is unimportant for spin relaxation. This is because all spin-dependent parts of the e-ph interaction are short-ranged, while Fröhlich interaction is the only long-range part of the e-ph interaction but is spin-independent. This important conclusion again emphasizes the ...
activity of a 379-nodes whole-brain network. Each node consists of one excitatory and one inhibitory population that mutually and recurrently interact. To simulate long-range white matter coupling, the neural masses were connected by each participant’s SC, which were estimated by dwMRI tractograp...
