Hospital terms
CR MR CT DR DSA X-ray is a type of medical imaging disease diagnosis. MRI is a magnetic resonance imaging examination, which can obtain cross-section, sagittal Planar and coronal images. Good spatial resolution. CT is an X-ray diagnostic device, a complex X-ray device that can obtain cross-sectional images. Compared with MRI, its characteristic is high density resolution. CR, DR and X-ray diagnosis, like CT, also use X-rays to complete images. The difference is that CR and DR are more advanced in image acquisition than ordinary X-ray machines. CR is an IP board, and DR is more advanced and is completed through PACS. Simply put, there is no obvious difference in the scope of their diagnosis. Cr is the abbreviation of the adjective cardiorespiratory, which means "cardiopulmonary".
Physiological terms
The abbreviation of serum creatinine. All creatinine is filtered out by the glomerulus. It is not absorbed by the renal tubules and rarely excreted. It basically represents the glomerular filtration rate [GFR]. , Serum creatinine (Cr) is normal for men: 44~133μmol∕L (0.5~1.5mg∕dl)
Women: 70~106μmol∕L (0.8~1.2mg∕dl), which is not the early stage of renal function damage. index.
The increase is clinically significant (seen in any disease that causes glomeruli to decrease. For example: acute and chronic renal failure)
