What is the experience of having an abdominal CT?

Abdominal CT, during the process, the speaker will prompt "take in, hold the breath", or other similar breath-holding voice prompts. In particular, some patients will say "Doctor, you help me do it carefully", but the fact is that no matter how careful the doctor is, if you move during the examination, it will be all in vain, and it will definitely not be clear, so you must stay still. I think that's the most important thing.

A CT scan will increase the risk of radiation cancer for the examinee8, and when you do a CT of the abdomen, you are worried that you will die in it.

The most important thing to pay attention to when doing a CT scan is to stay still. Similar to shooting, as soon as you move, the image will be blurry.

During the abdominal CT test, I did not eat any food 4 hours before the examination, and I felt that I was about to go hungry.

Do not take metal drugs during abdominal examination, and do not do gastrointestinal photography. The patient should remove metal objects such as hairpins and earrings from the head. And bring the previous inspection materials.

For abdominal scanners, barium imaging should not be done within 1 week before the examination, so as to avoid the formation of artifacts in the residual contrast agent in the intestine, which will affect the quality of CT images and lead to misdiagnosis.

I don't feel anything, just follow the instructions.

CT is irradiation, ** there is static electricity on it, which may be felt by sensitive people, but I don't know if it's right.

For abdominal scanners, fast for 4 hours before the examination, do not take laxatives within the first 2 days, and eat less fruits, vegetables, soy products and other slag and gas-producing foods.

I did abdominal enhancement CT, and I didn't feel anything, except that the contrast agent was injected in and made me shiver.

Remove metal objects from your body, such as headwear, earrings, necklaces, etc., and do not wear clothing with metal accessories, as these items can cause metal artifacts when scanning, which will affect the image quality.

I was taken three times when I had a CT scan of my abdomen, and I was really afraid that I would be exposed to strong radiation.

What can CT experience? Just don't move, and you don't feel it.

I'm going to do a lung CT and take a picture of my head and show it to the doctor, and the doctor said that it was taken wrong, and I whispered to the CT side that I opened the lungs, how did you shoot the head, and I took it twice, and I was really angry, and I couldn't show it.

An indwelling needle was applied, and the abdomen was scanned while the contrast agent was injected.

I was a little scared when I did the enema.

Fasting. Eating can affect the imaging results of the gallbladder and stomach. High alpha-fetoprotein in liver cirrhosis not only depends on whether the liver occupies a mass, but also depends on the gallbladder, bile ducts, stomach wall and surrounding tissues.

Whether fasting is required for CT depends on what is done.

Bit. Head CT does not need to be fasting, and it has no effect to do it after eating, and it is okay to do head CT for dizziness. If you do a CT scan of the digestive system, it is theoretically necessary to perform an empty stomach.

It is recommended that if you are dizzy, there are many reasons, so in addition to doing a head CT, you should take another test of your blood pressure, do an electroencephalogram and so on.

CT scan.

It is a relatively advanced and widely used imaging examination method at present. It mainly acts on the nervous system, respiratory system, bone volume and bone system, and reproductive system. With the exception of the digestive system, all other systems are not affected by dietary habits.

Because in the process of CT examination of the digestive system, if you eat, the food of the digestive system will affect the imaging of the stomach and intestines, and these food residues can easily lead to the corresponding lesions being covered, and this situation will be missed accordingly. At the same time, after eating, it will also cause the corresponding liver and gallbladder to contract, which is not conducive to the detection of corresponding diseases.

Depending on where it is, the abdomen needs to be fasting, and nothing else is needed.

CT generally don't have an empty stomach! It's not a gastroscopy, a lab or something.

The abdominal cavity needs to be fasted, not the cervical spine.

It depends on which part you do, generally not.

No, you don't! Generally not needed!!

You don't need to be on an empty stomach to do this.

CT examination is divided into non-contrast CT and CT enhancement, and many parts can be examined. If a non-abdominal examination is done, there is no need to fast. The area of the abdomen needs to be checked on an empty stomach, and a fasting patient should be asked to drink water when he comes to the hospital.

If the examination is not enhanced, the patient is generally asked to drink water containing 1%-2% contrast agent to fill the intestines and stomach, so that the examination effect will be better and the vision will be clearer. In the case of a contrast-enhanced test, the patient is asked to drink simple water, and the stomach and intestines are also filled, and the amount of water to drink and the time to drink are determined according to the upper and lower abdomen. Therefore, whether or not to fasting for CT examination mainly depends on the purpose of the examination.

For example, there are also retroperitoneal examinations, where the patient does not have to be fasting. For example, in the abdomen, even if it is an examination of abdominal organs, but in an emergency, there is no need to fast.

Conclusion: To have an empty stomach.

Brief description: CT is to use X-ray beam DU to scan the DAO layer of a certain thickness of a certain part of the human body, and after a series of optical and internal electrical transformations, it can be accommodated to the purpose of checking the state of various organs of the human body.

If you do not fast, due to the presence of food, it will lead to optical refraction, which is prone to errors and affect the test results, so CT examination needs to be fasting!

CT examination of most parts or organs is convenient and fast, and does not require too much preparation, just ask the patient to remove high-density or metal objects from the examination site before the examination, and conduct breath-holding training on the patient during the examination to obtain the patient's cooperation. One of the reasons why abdominal CT is different from other CT scans is that the preparation for the examination is complicated.

Preparation of the patient before the examination.

1) Through inquiry, understand the patient's condition and mental outlook, and ask the patient's family or medical staff to accompany him according to the condition.

2) Except for the emergency department, fast for 4-8 hours before the examination.

3) Remove high-density or metallic objects from the inspection site before the examination.

4) Perform the necessary signing procedures for patients who need enhanced scanning.

5) Do not take drugs containing heavy metals within a week, otherwise a clean enema should be taken.

6) Gastrointestinal barium contrast is not done within one week, because the density of the barium sulfate contrast medium used in the contrast is higher than that used in CT examination, and the image will be artifact under the action of X-ray.

Analysis: Hello, your situation is mainly due to high alanine aminotransferase index, so it is generally important to focus on CT scan of the upper abdomen to understand whether there are abnormal lesions in the liver. It is not a contraindication to intensive CT during the menstrual period, and the main contraindications to intensive CT scan are usually as follows:

Diabetes, kidney disease, heart disease, asthma, allergies, pheochromocytoma, myasthenia gravis, multiple myeloma, sickle cell disease, etc., can be tested if you only have abnormal liver function. Suggestion: Enhanced CT scan requires a certain amount of contrast agent to be injected intravenously at the same time.

In general, contrast agents are safe for humans. However, due to the individual differences in the human body, in specific circumstances, some people will have some adverse reactions to the contrast agent, including allergic reactions and neurotoxicity, vascular toxicity, nephrotoxicity, etc., among which allergic reactions are the most common, but the doctor usually does an iodine allergy test for you 15 to 20 minutes before the examination, and it is recommended that you choose a non-ionic contrast agent, which is relatively safe. It should also be noted that you need to be fasting before the examination, and you must be accompanied by at least one of your family members for the examination, and you need to remove items containing metal from the outside of the body during the examination, and the enhanced CT scan is generally divided into three phases, so you are required to adjust the breath-holding state under even breathing each time to ensure the effect of the examination.

Generally, after the examination, the doctor will leave you for 15 minutes, if there are no adverse reactions, you can leave the CT room, and you don't need to pay attention to anything else. Best wishes.

Analysis: Abdominal CT examination is to find out whether there are infectious diseases in the abdominal organs, such as inflammation, tuberculosis, abscess, etc.; Whether there is a mass, such as benign or malignant tumors, metastatic tumors, etc.; Whether there are deformities, stones, obstructions, perforations, effusions, etc. Before the examination, the patient needs to drink an aqueous solution containing iodine contrast medium 2%.

Suggestions and suggestions: The purpose is to let the contrast medium fill the entire intestinal lumen to reduce the artifacts caused by intestinal gas accumulation and affect the diagnostic effect; Second, after the intestinal tract is full, it is convenient to make a differential diagnosis of the disease. Therefore, you need to wait a while after drinking the contrast medium until it reaches the intestinal lumen of the area to be examined.

Abdominal CT must be done on an empty stomach. 1. If you are doing CT of the gastrointestinal tract, you also need to prepare the gastrointestinal tract, not only on an empty stomach, but also need to drink a lot of water before the examination, and even inject injections, such as 6542, to make the gastrointestinal tract in a dilated and relaxed state; 2. If the patient eats a lot of food for CT, a lot of food in the stomach and the gas in the gastrointestinal tract will affect the doctor's judgment of the lesion; 3. Drink a lot of water before doing abdominal CT, drinking water is to support the stomach and set it off well for easy examination.

In non-emergency settings, abdominal CT requires the patient to fast for 5 to 8 hours the night before and on an empty stomach the next day. The goal of fasting is to keep the gastrointestinal tract empty and avoid the gastrointestinal contents affecting the diagnosis.

If the abdomen CT is performed, the gallbladder needs to be observed, and if the patient eats before the examination, the gallbladder needs to be emptied of bile for digestion, and the filling is not high, and the diagnosis cannot be accurately made. In addition, patients who are examining the gastrointestinal tract need to drink 500-1000ml of water to fill the gastrointestinal tract before the examination, as it will cause discomfort if the patient eats before the examination.

Some patients experience an allergic reaction to the enhanced scan, resulting in nausea and vomiting, and eating may lead to life-threatening aspiration.
