What does Cr mean in medicine, and what does cr mean

In fact, it is a kind of image, which is used for perspective, and it is said that it should be.

Both CR images and conventional X-ray images are overlapping images of the entire photographed area, so the parts that can be captured by conventional X-ray can also be imaged with CR, and the observation and analysis of CR images are the same as those of traditional X-rays. The difference is that a CR image is made up of a certain number of pixels. CR is superior to traditional X-ray imaging for bone structure, junction cartilage and soft tissue, and can also be used for quantitative analysis of mineral salt content.

CR tends to visualize mediastinal structures such as blood vessels and trachea. Nodular lesions are more likely to be detected than traditional x-ray imaging, but interstitial and alveolar lesions are not as good as traditional x-ray imaging. CR is superior to traditional X-ray images in the observation of calcium-containing lesions such as pneumogas, pneumoperitoneum, and stones.

Tomography with CR is superior to radiography. Gastrointestinal double-contrast contrast contrast is superior to conventional X-ray imaging in showing gastric cells, minimal lesions, and intestinal mucosal folds.

Hospital terminology. CR MR CT DR DSA X-RAY are all a type of medical imaging disease diagnosis, MRI is a magnetic resonance imaging examination, which can obtain cross-sectional, sagittal and coronal images. Good spatial resolution.

CT is an X-ray diagnostic device, a complex X-ray device that obtains cross-sectional images. Compared with MRI, it is characterized by high density and resolution. Diagnosis of CR and DR and X-rays is done by X-rays just like CT.

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 done through PACS. To put it simply, there is no too obvious difference in the scope of their diagnosis, which is an abbreviation of the adjective cardiorespiratory, which means "cardiopulmonary".

Physiological terms.

Abbreviation of serum creatinine, creatinine is all filtered out by the glomeruli, renal tubules are not absorbed, rarely excreted, basically represents the glomerular filtration rate of GFR, serum creatinine (CR) normal male: 44 133 mol L ( ).

Female: 70 106 mol l( ) is not an early indicator of renal impairment.

Elevated is clinically significant (seen in any disorder that causes glomerlows. e.g., acute and chronic renal failure).

You're talking about creatinine, which is a metabolic value that evaluates kidney function.

CR: Cathode ray or conditioned reflex.

Computerized radiography system.

I don't know if you're talking about the median relationship (CR).

CR** is relatively inexpensive, and a set of CR can realize the digitization of X-ray equipment in the whole hospital.

Summary. Expand your knowledge of the chemical symbol CR, with an atomic number of 24, which belongs to group B in the periodic table. The name of the element comes from the Greek word for "color", because chromium compounds have color.

The elemental material is steel-gray metal, which is the hardest metal in nature. The content of chromium in the earth's crust is the 17th. Natural chromium in its free state is extremely rare and is mainly found in chrome-lead ore.

You crack well, CR, is an Internet buzzword. The word is an abbreviation of created, which is "from", and is generally used in Weibo. The word CR is an abbreviation for created. Extended meaning: Hongyin means "from".

Medical CRC means:Clinical Research Coordinator.

1. Definitions: A Clinical Research Coordinator (CRC) means:Clerks who assist the investigator in making non-medical judgments in clinical trials with the authorization and consent of the principal investigator and after training。Responsibilities include:Dispensing medicines, communicating with subjects, and keeping in touch with investigators, etc

CRC is a specialized profession as a member of clinical research.

Second, the content of the work.

Safeguard the rights and interests of subjectsIt is the umbrella of the subject's rights。(The purpose of a clinical trial is different from that of a medical service, and it is quite difficult for a clinician to assume the dual role of conducting a clinical trial and providing medical services at the same time.) CRC can help to be informed, face adverse reactions, save costs, shorten waiting times, etc.).

Ensure the scientific nature of clinical trials. （This includes an assessment of the feasibility of the protocol prior to the trial; Ensure that the subjects who are included in the group are randomized; Enhance the compliance and care of the subjects; The discovery, tracking, and reporting of adverse events make the drug safety evaluation tend to be correct and reasonable; Prevent or reduce deviations from the protocol: time window, management of various clinical examinations, and important links to ensure the smooth progress of the laboratory examination process; The CRC is the first to read, finds outliers or abnormal changes, and communicates them to the researcher in a timely manner.

Because CRC is familiar with the protocol, it will also give suggestions and reminders to the investigators).

3. Improve the credibility of clinical trial data quality

1) Ensure data uniformity: under the guidance and supervision of CRC, patients should undergo physical or laboratory examinations under the same conditions as much as possible; For subjective evaluation items such as pain level and filling in the patient diary, the data obtained by the guidance of the uniformly trained CRC are more reliable.

2) Ensure data integrity: The process arrangement prepared for each patient and the diagnosis and treatment record form made with reference to the CRF are pasted on the medical record as the original data to ensure that the data is collected without omission.

3. Improve the credibility of clinical trial data qualityEnsure the timeliness and correctness of data transcription. Ensures that the original material is transcribed to paper or electronic CRF in a timely manner, and there are fewer errors in transcription.

Problems are found during the transcription process and discussed with researchers in a timely manner to reduce questions about the data in the future. Assurance of Audits. In the past, medical institutions were reluctant to receive monitoring and inspection personnel, so CRC prepared monitoring or inspection materials for them in advance, accompanied the on-site work of monitoring and inspection personnel, and answered questions in a timely manner or communicated with researchers in a timely manner, so that monitoring and inspection could be smoothly implemented.

CR means Carriage Enter.

In C it is the character''meaning. The C language is a process-oriented, abstract general-purpose programming language, which is widely used in low-level development. C can compile and process low-level memory in a simple way.

C is an efficient programming language that produces only a small number of machine languages and does not require any runtime environment support.

In text processing, cr, lf, cr lf are line breaks used on different operating systems. DOS and Windows use carriage enter + newline CR lf for the next line, while UNIX Linux uses the newline lf for the next line.

Text processing in the c language

Mac (Mac OS) uses the carriage return cr to represent the next line, and cr uses a symbol''Indicates that the decimal ASCII is 13 and the hexadecimal is 0x0d; LF use''The symbol indicates that ASCII** is 10 and the sixteenth system is 0x0a.

Therefore, the word wrap on the Windows platform is represented by 0d 0a two bytes in the text file, while the line break on the Unix and Apple platforms uses a byte table of 0a or 0d, and the runtime library on the general operating system will automatically determine the wrap format of the text file.

CR stands for Current Ratio.

Current ratio refers to the ratio of total current assets to total current liabilities. It is used to measure the ability of a company's current assets to be converted into cash to repay liabilities before short-term debt maturity. The higher the current ratio, the greater the liquidity of the company's assets, however, a large ratio indicates that the current assets occupy more, which will affect the efficiency and profitability of operating capital turnover.

Hello, it is a low-alloy high-strength structural steel with good plasticity, welding performance and impact toughness, cold and hot processing performance and low and medium temperature performance is also very good, and has a certain corrosion resistance. Q295A can be used to manufacture stamping parts for vehicles, building structural parts, medium and low pressure chemical containers and low-pressure boiler steam drums, sheet stamping parts, and oil pipelines.

cr is generally used in Weibo, quoting other people's **, etc., will use these two kinds of means to indicate that this content was created by someone, that is, from a certain place and people.

In Weibo, CR is the current ratio; It is the ratio of current assets to current liabilities, which is used to measure the ability of current assets of an enterprise to be converted into cash to repay liabilities before the maturity of short-term debts. Generally speaking, the higher the ratio, the stronger the liquidity of the company's assets and the stronger the short-term solvency. The opposite is weak. It is generally believed that the current ratio should be changed to 2:

1 or above, the current ratio of 2:1 means that the current assets are twice the current liabilities, and even if half of the current assets cannot be realized in the short term, the entire current liabilities can be repaid.
