What does CR mean in medicine?

Cr, Mr, CT, DR, DSA and X-ray are all kinds of medical imaging diagnosis. MRI is a magnetic resonance imaging examination, which can obtain images of cross-section, sagittal plane and coronal plane. Good spatial resolution. CT is a kind of X-ray diagnostic equipment, and it is also a complicated X-ray equipment, which can obtain tomographic images. Compared with MRI, it is characterized by high density resolution. CR, DR and X-ray diagnosis, like CT, all complete images through X-rays. The difference is that CR and DR are more advanced than ordinary X-ray machines in image acquisition. CR is an IP board, and DR is more advanced, which is completed by PACS. Simply put, there is no obvious difference in their diagnostic range. Cr is the abbreviation of adjective cardiorespiratory, which means "cardiorespiratory".

Physiological terminology

The abbreviation of serum creatinine is completely filtered out of the glomerulus, not absorbed by renal tubules, and rarely excreted, which basically represents glomerular filtration rate ([〔GFR], and serum creatinine (Cr) is normal: 44 ~133 μ mol ∕ L (0.5 ~1.5 mg ∕ DL).

Female: 70 ~106 μ mol ∕ l (0.8 ~1.2 mg ∕ dl) is not an early indicator of renal function damage.

This increase has clinical significance (see any disease that leads to glomerular decrease). Such as: acute and chronic renal failure)
