How does the CT scan machine work?

Let's talk about how a CT scan works.

With the development of CT scan devices, it is possible to take pictures of all parts of the human body.. If you are curious to know how CT scan works, we must say very simply and briefly that with the help of CT scan devices, X-rays are irradiated to the body and when the rays are transmitted to the tissues in the form of electric current, it is called information.. The detector transmits this information to a powerful computer, and the result is images.. Registration is done give.

The CT scan machine, which is circular in shape and has a bed in the middle, is usually placed inside a room with relatively cool air.. Next to the CT scan room, there is a control room where the machine's computers are located, and the technician controls the machine from there and performs imaging operations... during the CT scan, only the patient is in the machine room, and the technician leaves the room after guiding the patient to take the correct position, and through the glass window, the patient's condition examines and talks to him.

In order for the imaging to be performed correctly and accurately, the patient must remain motionless during the CT scan.... For this purpose, it may be fixed on the bed with adhesive tape.

The things that we should pay attention to before performing a CT scan of body parts without injection are:

1.... The insurance book must be valid until the day of the CT scan... Having a valid insurance book is an important point that we sometimes forget, and this sometimes causes the CT scan center to not be able to do its work properly and we have to take another appointment.

Completion of CT scan with injection of contrast liquid

In some cases, to increase the clarity of the CT scan images and better diagnose the complication, the injection of a contrast agent is used... Due to the entry of these substances into certain organs of the body, blood vessels or tissues, the contrast of the images increases and the diagnosis of abnormalities becomes more accurate.

Contrast material enters the body in several ways:

• Swallowing
• Enema or enema through the anus
• intravenous injection
• local injection

It should be said that these substances usually have mild side effects that are either absorbed by the body or removed from the body through urine and feces.

In cases where you need to perform a CT scan with the injection of contrast material, in addition to following the general CT scan procedures, you should also pay attention to other points, which include:

1.... You must fast 6 hours prior to doing a CT scan...

3... Creatine and PH test should be done one day before the CT scan, and the patient should refrain from doing other tests such as thyroid and... for a week after the CT scan as much as possible... Be careful that patients who take certain medications do not stop taking the medication without a doctor's prescription.

4... If you are pregnant, be sure to discuss this with your doctor.... Take this issue very seriously, radiation can have a serious negative effect on the health of the fetus...

5... If you are breastfeeding, it is better not to breastfeed the baby for 24 hours after the injection of the contrast agent... The contrast liquid is usually removed from the body in less than 24 hours, after that there will be no problem to breastfeed the baby.

6... Patients who take metformin from 48 hours before to 24 hours after a CT scan should stop using it only with the doctor's opinion.

7.... If you have allergies, including asthma, drug sensitivity, etc., consult your doctor before CT to prescribe anti-allergic medication.

8... Drinking plenty of fluids up to 2 days after the injection test is recommended.... Drinking fluids causes more urination and faster removal of the injected fluid from the body...
