CT oncoscreening. Early oncology detection
Oncological diseases are becoming more common. Cancer leads to a mutation of healthy cells into malignant. The body essentially eats itself. The main danger is that in the early stages, when the percentage of successful overcoming of the disease is maximum, there may be no symptoms at all or they are insignificant.
The primary symptoms that may indicate the presence of oncology include:
- • fast fatiguability;
- • decreased appetite;
- • discoloration of the skin;
- • pain;
- • weight loss;
- • general malaise;
- • a yellowish tinge appears (if it is cancer of the liver or pancreas).
Such symptoms are often ignored and attributed to everyday stress or lack of vitamins. The specificity of mentality and lifestyle also affects the decision to seek help from specialists. Moreover, even in the case of treatment, traces of neoplasms are not always detected. For the most accurate results, you need to resort to modern diagnostic methods, such as ultrasound, MRI or CT
CT oncoscreening is the most effective diagnostic method, which helps with high accuracy to obtain basic data on the presence and condition of neoplasms. In addition, it actually has no contraindications and is carried out quickly. The advantage is the detection of neoplasms in the early stages and with minimal size. This is one of the most accurate methods that can determine the presence of the first foci of onco.
When oncoscreening may be needed:
- • in the presence of neoplasms (tumors);
- • excessive stress levels;
- • bad habits in the patient;
- • age after 35 years;
- • burdened hereditary history;
Contraindications for CT: no
Limitations for CT: pregnancy, kidney or liver failure, weight more than 150 kg, allergy to iodine-containing substance.
Time: up to 40 minutes (with contrast).
Indications for bolus administration:
- • suspicion of a tumor;
- • for a better examination of soft tissues.
Using a bolus, you can get a more detailed picture with the possibility of reconstructing the frontal and longitudinal images.
The goals of CT diagnostics:
- • determination of tumor size;
- • check for metastases;
- • accurate imaging of the tumor;
- • examination of the condition of the lymph nodes;
- • determination of the degree of spread of the tumor.
To clarify the nature of the tumor, special tests (verification) are performed, such as a biopsy, scrapings, or puncture. These are diagnoses that are made on particles of infected tissue.
How is CT oncoscreening performed:
In most cases (with the exception of breast cancer), the administration of a contrast medium is necessary, therefore, 6 hours before the examination, you need to refrain from eating. The introduction of a bolus does not bring discomfort or pain. Light heat radiates throughout the body. The introduction of the drug is carried out gradually during the scan.
What is the advantage of introducing contrast – it accumulates directly in the tumor itself. It is filled with this iodine-containing substance and it becomes better visible on the projection.
It must be remembered that before the diagnosis itself it is important to remove metal objects, because they can interfere with obtaining an accurate image and create layers in the picture. The patient lies on a retractable couch and drives into the tomograph ring. The mechanism turns on and the ring with sensors moves around the area being examined. The three-dimensional picture is transferred to the computer. The patient communicates with the doctor through a feedback device.
Getting and processing the results takes no more than an hour. A three-dimensional image and a doctor’s opinion are issued to the patient’s hands (on a flash drive) or sent to e-mail
