Does the medical equipment test instrument have radiation?

I believe everyone is familiar with ct examination, which belongs to a fully functional disease detection instrument. It belongs to a very powerful electromagnetic energy, which can carry a lot of energy and can better penetrate most of the soft tissues of the human body, thus recording the outline of the human skeleton, but ct will bring some harm to the body.

The harm of ct scanning to human body mainly comes from some ionizing radiation produced by X-rays. This ionizing radiation mainly interacts with substances in human cells and body fluids, resulting in molecular ionization of substances, so it will directly destroy some macromolecular structures in the body, easily lead to protein molecular breakage and RNA breakage, thus destroying some enzymes important for substance metabolism, and even directly destroy human cell structure. Ionizing radiation mainly ionizes a water molecule and then forms free radicals, which will indirectly harm the human body.

What are the advantages of ct scanning?

Ct scanning is convenient and quick, especially easy for patients to accept, and it belongs to non-invasive examination. Ct has high-density resolution and can better detect the ct values of various tissues in the body. Ct images are very clear and have a clear anatomical relationship. Ct can provide some single-sided images without overlapping tissues.

Moreover, sagittal or coronal images can be reconstructed, and contrast agent can be used for enhanced scanning, which can not only effectively find some lesions, but also make some diagnoses.
