Magnetic Resonance Imaging (MRI) is a medical imaging technique used to visualize internal structures of the body in detail. It uses a strong magnetic field and radio waves to generate images of organs, tissues, and other structures without the use of ionizing radiation (such as X-rays). 

 Before undergoing an MRI scan, the patient may be asked to remove any metal objects or jewelry, as they can interfere with the magnetic field. The patient may also need to change into a hospital gown, depending on the area of the body being imaged. Patients with certain medical implants or conditions may need to inform the radiologist or technologist before the scan.

 The patient lies down on a padded table that slides into the MRI machine, which is a large, tunnel-like structure. Depending on the area of the body being imaged, the patient may be positioned feet-first or head-first into the machine. Some MRI machines are open on the sides, which can help reduce feelings of claustrophobia.

 In addition to the main MRI machine, specialized coils may be placed around the area of the body being imaged to improve image quality. These coils act as antennas to detect the radio signals emitted by the body's tissues in response to the magnetic field.

 Once the patient is properly positioned, the MRI technician leaves the room and starts the scan from a separate control room. The MRI machine generates a strong magnetic field and emits radio waves, which cause hydrogen atoms in the body's tissues to align and emit signals. These signals are detected by the coils and used to create detailed cross-sectional images of the body. The raw data collected by the MRI machine is processed by a computer to generate high-resolution images of the internal structures being examined. These images can be viewed in different planes (such as axial, sagittal, and coronal) and manipulated to highlight specific tissues or abnormalities.

 After the scan is complete, a radiologist reviews the MRI images to evaluate the anatomy, identify any abnormalities or pathology, and provide a diagnosis. The radiologist may compare the MRI findings with other imaging studies (such as X-rays, CT scans, or ultrasound) to gather additional information. Depending on the results of the MRI scan, further diagnostic tests or treatments may be recommended. The patient and referring healthcare provider receive a report of the MRI findings, which guides further management and care.

MRI imaging is widely used in medicine for diagnosing a variety of conditions, including injuries, tumors, infections, and neurological disorders. 

Bulgaria has few clinics and hospitals but some are well reputed and the medical offer of Bulgaria covers all medical treatments. If most clinics are located in Sofia and its outskirts, some cities like Pleven or Varna offer few hundreds hospital beds. Some dental clinics are well known from foreign patients while plastic surgery is one of the medical category offered in Bulgaria.
