The term **«Диагностика МРТ КТ ПЭТ»** (in English: *Diagnostics MRI CT PET*) refers to a set of modern medical imaging methods used to assess internal organs and tissues for diagnostic purposes:

- **МРТ (магнитно-резонансная томография / MRI)** - Magnetic Resonance Imaging, which uses magnetic fields and radio waves to produce detailed images of soft tissues and organs.
- **КТ (компьютерная томография / CT)** - Computed Tomography, which uses X-rays to create cross-sectional images of the body, useful for examining bones, lungs, and detecting internal bleeding.
- **ПЭТ (позитронно-эмиссионная томография / PET)** - Positron Emission Tomography, which provides functional imaging by detecting metabolic or biochemical activity, often used in oncology, neurology, and cardiology.

Together, these diagnostic tools allow doctors to obtain both structural and functional information about the body for accurate diagnosis and treatment planning.
