Spiral computed tomography
It is known that half of the success of the treatment of any disease lies in the accuracy of the diagnosis. Alas, it is still not uncommon for a patient to be treated for one disease for years, and then it turns out that he is sick with a completely different one, just the symptoms are similar. During the time of improper treatment, the disease does not stop in development, taking on a chronic course and stubborn nature. Diagnostic errors are especially dangerous in oncology, where they can cost lives, since malignant tumors in the later stages become practically incurable. In light of this, it becomes clear why spiral computed tomography is so in demand in modern medicine.
Spiral computed tomography is a high-tech method for examining internal organs, which is based on X-ray diagnostics. The advantages of spiral computed tomography make it the method of choice for diagnosing many pathologies of internal organs, since method a) is characterized by high accuracy (error within 1 mm) and b) allows obtaining results quickly, faster than with conventional computed or magnetic resonance imaging.
What happens during a spiral computed tomography session? As with conventional CT, the patient table moves slowly, but the X-ray tube also rotates around the patient. Thanks to this, one more advantage of spiral computed tomography is achieved: a lower radiation load on the body. The study allows you to take pictures in any direction, both longitudinal and transverse, the step of which is equal to one millimeter. In other words, the doctor has a 3-D image of the desired area. At the same time, the accuracy is amazing, since all types of tissues, including soft ones, are well distinguishable and detectable. The error does not exceed 1.5-2%, for comparison, the error of a conventional X-ray image is about 10-15%.
Conventional computed tomography and magnetic resonance imaging allow you to "see" neoplasms larger than 7mm. This is quite small, but not when it comes to malignant tumors. For many types of tumors, 7mm is already a serious stage of development, when the initial stage is irretrievably missed. If you suspect such conditions, it is spiral computed tomography that will help, since it allows you to detect neoplasms up to 1 mm in size.
The spiral computed tomography method is reliable, fast and accurate; it has only one drawback - a relatively high cost, since it requires expensive equipment. However, nothing is more precious than life, and SKT helps to save it.
