Magnetic resonance cholangiopancreatography (MRCP) is a medical imaging technique. It uses magnetic resonance imaging to visualize the biliary and pancreatic ducts non-invasively. This procedure can be used to determine whether gallstones are lodged in any of the ducts surrounding the gallbladder .
MRCP may be: Magnetic resonance cholangiopancreatography , in medical imaging, a technique to visualise the biliary tract and pancreatic ducts. Membership of the Royal Colleges of Physicians of the United Kingdom , a postgraduate medical diploma run by the Federation of the Medical Royal Colleges of the United Kingdom
Methallyl chloride Phenyl lithium (base) LiCl + PhH 1-Methylcyclopropene The phenyllithium should be free of lithium halides. The corresponding reaction of allyl chloride and phenyllithium main affords cyclopropylbenzene. Isomers Methylcyclopropene can refer to either of two isomers, 1- methylcyclopropene covered in this article, or 3- methylcyclopropene which is not covered in this article ...
The CRC Handbook of Chemistry and Physics is a comprehensive one-volume reference resource for science research. First published in 1914, it is currently (as of 2024 [update] ) in its 105th edition, published in 2024.
MDCalc is a free online medical reference for healthcare professionals that provides point-of-care clinical decision-support tools, including medical calculators, scoring systems, and algorithms. [1] MDCalc is also a mobile and web app. [ 2 ] The decision-support tools are based on published clinical research, [ 3 ] and MDCalc’s content is ...
Here, 1 / f eq is an integer value. Each solute can produce one or more equivalents of reactive species when dissolved. In redox reactions, the equivalence factor describes the number of electrons that an oxidizing or reducing agent can accept or donate. Here, 1 / f eq can have a fractional (non-integer) value.
Electrospray parameters include electrospray voltage, gas and liquid flow rates. Chemical parameters refers to the sprayed solvent composition, e.g. addition of NaCl. Geometric parameters are α, β, d 1 and d 2 (see figure on the right). Furthermore, α and d 1 affect the ionization efficiency, while β and d 2 affect the collection efficiency ...
For example, 3-methyl-1-pentene with a rectus assignment is formatted as (R)-3-methyl-1-pentene. [12] An example of a (s) descriptor: (1R,2s,3S)-1,2,3-trichlorocyclopentane. A practical method of determining whether an enantiomer is R or S is by using the right-hand rule: one wraps the molecule with the fingers in the direction 1 → 2 → 3.
