Structure and properties Meglumine or -methyl-D-glucamine (C7H17NO5, Mr = 195.2 g/mol) exists as a white crystalline powder that is readily soluble in water. It carries an amino group which is protonatable. Fields of application Some contrast agents exist as meglumine salts. In this case, meglumine serves as an organic salt former.
Do I need contrast medium? Contrast agents are used to improve the representation of structures. The MRI images are black and white, and since there are not infinite shades of grey, it is sometimes difficult to distinguish between different tissues. For the diagnosis of stroke, the diffusion MRI is particularly important. Diffusion MRI shows areas … Do I need contrast medium? | MRI for a stroke
What is an MRI for a stroke? MRI (magnetic resonance imaging) is a diagnostic procedure that uses magnetic fields and radio waves to create an image. With MRI, even small strokes can be visualized very well and, above all, much earlier than with CT (computed tomography). This article explains why the CT examination is nevertheless … MRI for a stroke
Can any stroke be detected with MRI? The MRI has a great resolving power, so that even small strokes can be detected. Nevertheless, there are tiny strokes and even bleedings that escape the MRI. If MRI is used as an imaging technique in the acute phase of an ischemic stroke, it should be noted that … Can any stroke be detected with MRI? | MRI for a stroke
Ductoscopy is a modern examination procedure that allows the milk ducts in women’s breasts to be mirrored from the inside. The main indication for this form of diagnostics is the secretion of unclear, mainly reddish fluids from the nipple. By assessing the respective milk duct, it is possible to detect even small changes with the … Ductoscopy: Treatment, Effects & Risks

Magnetic resonance imaging is often referred to as MR or MRI. In medicine, magnetic resonance imaging is a so-called imaging procedure. What is magnetic resonance imaging? Magnetic resonance imaging (MRI) is an imaging procedure. It is mostly used for diagnosis and to visualize the structure and function of tissues and organs. This means that magnetic … Magnetic Resonance Imaging: Treatment, Effects & Risks
Saltatory excitation conduction ensures sufficiently fast conduction velocity of neural pathways for vertebrates. Action potentials jump from one unisolated cord ring to the next on isolated axons. In demyelinating diseases, the insulating myelin is degraded, disrupting excitation conduction. What is saltatory excitation conduction? Saltatory excitation conduction ensures sufficiently fast conduction velocity of neural pathways for … Saltatory Excitation Conduction: Function, Role & Diseases
