Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to generate images of the organs in the body.
The common procedure for a DCE-MRI exam is to acquire a regular T1-weighted MRI scan (with no gadolinium), and then gadolinium is injected (usually as an intravenous bolus at a dose of 0.05–0.1 mmol/kg) before further T1-weighted scanning. DCE-MRI may be acquired with or without a pause for contrast injection and may have varying time ...
Magnetic resonance myelography (MR myelography or MRI myelography) is a noninvasive medical imaging technique that can provide anatomic information about the subarachnoid space. It is a type of MRI examination that uses a contrast medium and magnetic resonance imaging scanner to detect pathology of the spinal cord , including the location of a ...
Fast low angle shot magnetic resonance imaging (FLASH MRI) is a particular sequence of magnetic resonance imaging. It is a gradient echo sequence which combines a low-flip angle radio-frequency excitation of the nuclear magnetic resonance signal (recorded as a spatially encoded gradient echo) with a short repetition time .
Multi-organ CT scans may help doctors identify those who may have a heightened risk of developing type 2 diabetes, a new study suggests. ... age of 45 who received a CT scan between January 2012 ...
Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15] MRI can be made sensitive to the motion of molecules.
Moreover, studies examining the impact of GLP-1 drugs on weight loss have reported considerable variation in the proportion of lean mass lost due to the same GLP-1 drug. Magnetic resonance imaging ...
NAFLD is often diagnosed through medical history, blood tests, physical exams and imaging tests, like ultrasound or MRI. These methods can help reveal fatty deposits in the liver and rule out ...
