CT, MRI, Ultrasound, And X-Ray: To Be Afraid Or Not?

Manifestations of many diseases take us by surprise, change our plans, disturb. On the one hand, the symptoms themselves can scare, and on the other, the need for a diagnosis. CT, MRI, ultrasound, and X-ray - is it harmful or not? And why several - is it possible to do one thing? What do you need to know about the most common methods of medical imaging today? How do they differ from each other? Which diagnostic method is right for you?

ultrasound-and-xray

In the arsenal of modern doctors, there are many diagnostic methods. At the same time, more and more people are talking about overdiagnosis. How does the patient understand that the study is really necessary? In what cases are CT, MRI, ultrasound, and x-rays prescribed?

On overdiagnosis in relation to the patient, we can talk in the case of self-designation. When patients who have some kind of complaints, they prescribe themselves some kind of examination without consulting a doctor- for example, after reading some article on the Internet.

The moment determining the choice of a diagnostic method is the estimated area of ​​damage. For example, if pathology from the pulmonary system is suspected, then the primary method will be radiological. The use of MRI, in this case, is impractical.

Therefore, before undergoing a study, it is better to first see a doctor, and then undergo one or another additional examination by MRI scan centre in New Delhi- both laboratory tests and instrumental diagnostics (ultrasound, CT, etc.). The only way is it possible, on the one hand, to be immediately examined purposefully, and on the other, to avoid unreasonable (often very tangible) material and time costs.

- Each of these research methods has a radiation load on the body?

No, only methods based on x-ray radiation (in particular fluorography, fluoroscopy, and radiography, CT). Ultrasound and MRI do not carry any radiation load, as they are based on other physical phenomena that have nothing to do with radiation.

- Magnetic resonance imaging and computed tomography, ultrasound and x-ray - which of these research methods is the safest, and which is the most informative?

The safest of them is an ultrasound scan, and also, in the absence of contraindications, an MRI. In terms of information, CT and MRI will be the leaders, but each in its “nomination”. For example, to detail the pathology of the lungs, CT is most informative, while when examining the brain- MRI.

- Is it true that to clarify the diagnosis, only one diagnostic method is not enough?

If we talk not only about the methods discussed above but about diagnostics in principle, then most often - yes. Diagnosis is a multi-component process. For example, an ultrasound revealed some kind of formation. To clarify its nature, MRI may be needed. Suppose tomography showed the presence of a tumor. But what kind of tumor is it? To answer this question, a biopsy may be necessary, sometimes even a diagnostic operation.

- If the patient has an alternative between CT and MRI - what to choose?

Again, it depends on what area of ​​the body, organ (s) are planned to be examined. If, for example, we are talking about the head or spine, then an MRI will be preferable. Often you can hear the question of what is the difference between MRI and CT scan cost in Delhi NCR, and which one is better. The basis of CT is the principle of x-ray radiation, and MRI - of the magnetic field. Both methods solve their own range of diagnostic tasks, and, if necessary, complement each other.
