Release date: 2006-11-14 Experts said: CT, nuclear magnetic examination have their own advantages Modern medicine is inseparable from laboratory tests, but in the face of those projects, many people are confused. In order to help everyone understand, from this issue, this edition opens up the "Sunshine Inspection" column to introduce the common clinical tests and inspection related knowledge. The high black wolfberry generally refers to the black wolfberry with a particle size between 0.4-0.5 cm. The granules are full and even with low anthocyanin content. It is generally described as the size of pepper or green bean.

In clinical work, doctors often encounter such problems: "The doctor gave me a CT, I heard that nuclear magnetic is the best, can I do nuclear magnetic", "the price of nuclear magnetic is expensive, can I make a CT?" In fact, magnetic resonance imaging (MRI) and computed tomography (CT) have their own advantages and cannot be replaced.
The imaging principles of MRI and CT are different. CT is imaged by X-rays penetrating the human body; MRI is imaged by signals emitted by hydrogen protons contained in the human body.
CT examination can be used in all parts of the body. It is sensitive to internal hemorrhage, calcification, bone, air and fat. It is especially used to observe intrahepatic hemorrhage or calcification, bone lesions (such as fractures, bone tumors and bone degeneration). Etc. There are also advantages in lung examinations, abdominal examinations, etc. In addition, CT imaging is very fast, especially suitable for the display of the heart and large blood vessels, of course, this requires a certain amount of iodine-containing contrast agent to be injected into the vein.
MRI is superior to CT in soft tissue examination, and is mostly used for neurological diseases (including cerebral infarction, inflammation, tumor, myelitis, spinal cord tumor, vertebral lesions, etc.) and abdominal, pelvic, limb soft tissue lesions. In some areas, the combination of CT and MRI can improve the sensitivity of the examination, such as soft tissue lesions but suspected of bleeding calcification.
MRI and CT have their own shortcomings. The biggest disadvantage of CT is radiation damage, but it is safe as long as it does not exceed the national prescribed dose and pay attention to protection. In addition, CT may have relatively heavy artifacts in some areas, such as the posterior cranial fossa (the back of the head).
Although MRI has no radiation and high contrast, the biggest drawback is that the inspection time is relatively long, so the requirements of the subject are relatively high. During the examination, the part to be inspected must not move, especially the examination of the abdomen and heart part requires the patient to suffocate for 5-20 seconds, otherwise the effect is not good.
CT has no absolute contraindications. Except for the advantages and disadvantages of pregnant women and newborns, it is suitable for all people under the premise of radiation protection. If you are allergic to iodine, you cannot perform a CT-enhanced scan.
MRI does not have the above contraindications, but patients with cardiac pacemakers and metal prosthetic valves can't do it. Patients with aneurysm clips, vascular stents, artificial joints, and metal internal fixation can't do it unless they have special instructions. Indicate an acceptable MRI exam. In addition, due to the long time of nuclear magnetic examination, the noise is large. For patients who cannot cooperate, such as children, unconscious, claustrophobic patients, if you do not take sedative measures, you can not do MRI.

Chaidamu black wolfberry is one of the main building plants in Qinghai desert Gobi area, and its natural habitat conditions are generally harsh. With strong resistance, strong germination capacity, drought tolerance and cold tolerance, it can form shrubs on desert, Gobi, barren hills and barren slopes. It is a fine plant resource with good wind and sand and sand fixation to keep soil and water. It has high ecological value. It plays an important role in preventing wind and fixing sand, improving desertification soil and preserving water and soil. It has high ecological application value in ecological environment construction.
Invigorating kidney and benefiting essence and preventing cancer: Black wolfberry and red wolfberry can make up the kidney and enrich the essence, and the anthocyanin (Anthocyanosides) in black wolfberry has the effect of removing free radicals, and can also prevent cancer cells from spreading smoothly, so as to protect more healthy cells from cancer cells. It seems that the pathogenesis of breast cancer is so, so taking anthocyanins will have a good inhibitory effect on the development of breast cancer.
The oil content of Lycium ruthenium is 5.54, and 3 main fatty acids are mainly unsaturated fatty acids. The content of linoleic acid is the highest, which is 7. 4. 8. It contains 17 kinds of amino acids. The content of glutamic acid was the highest (1.14%), followed by aspartic acid (1.11%) and methionine and cystine (0.14%). Protein content was 11.5%, total sugar 34.43%, reducing sugar 33.68%, Vc 212.11mg (100g) 1, moisture 10.31%. Lycium barbarum contains a certain amount of essential fatty acids and eight kinds of essential amino acids, as well as a certain amount of VC and Ve. The most important thing is that it contains more reducing sugar and pigment, and its pigment is the active ingredient of antioxidant and delaying senescence of black fruit and wolfberry, which can play a role in delaying senescence, and also has the effect of anti radiation, which has profound potential for development.
