Invasiveness of surgical procedures in the context of "Pulse oximetry"

Radiology (/ˌreɪdiˈɒlədʒi/ RAY-dee-AHL-ə-jee) is the medical specialty that uses medical imaging to diagnose diseases and guide treatment within the bodies of humans and other animals. It began with radiography (which is why its name has a root referring to radiation), but today it includes all imaging modalities. This includes technologies that use no ionizing electromagnetic radiation, such as ultrasonography and magnetic resonance imaging (MRI), as well as others that do use radiation, such as computed tomography (CT), fluoroscopy, and nuclear medicine including positron emission tomography (PET). Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above.

The modern practice of radiology involves a team of several different healthcare professionals. A radiologist, who is a medical doctor with specialized post-graduate training, interprets medical images, communicates these findings to other physicians through reports or verbal communication, and uses imaging to perform minimally invasive medical procedures The nurse is involved in the care of patients before and after imaging or procedures, including administration of medications, monitoring of vital signs and monitoring of sedated patients. The radiographer, also known as a radiologic technologist in countries such as the United States and Canada, is a specialized healthcare professional who performs radiographic procedures and radiation therapy for the diagnosis and treatment of diseases such as cancer. The images produced through radiographic procedures are used for interpretation by radiologists, and depending on their education, training, and the regulations of the country in which they practice, radiographers in some regions also have an extended role in image interpretation and reporting.

Lithotomy from Greek for "lithos" (stone) and "tomos" (cut), is a surgical method for removal of calculi, stones formed inside certain organs, such as the urinary tract (kidney stones), bladder (bladder stones), and gallbladder (gallstones), that cannot exit naturally through the urinary system or biliary tract. The procedure is usually performed by means of a surgical incision (therefore invasive). Lithotomy differs from lithotripsy, where the stones are crushed either by a minimally invasive probe inserted through the exit canal, or by an acoustic pulse (extracorporeal shock wave lithotripsy), which is a non-invasive procedure. Because of these less invasive procedures, the use of lithotomy has decreased significantly in the modern era.

The Federal Center of Neurosurgery in Tyumen (Russian: Федеральный центр нейрохирургии в Тюмени), the full official name is the Federal State budgetary institution the Federal Center of Neurosurgery of the Ministry of Health of the Russian Federation (Tyumen) — the medical institution built for high-tech neurosurgery health care. The target group of the hospital is the Ural Federal District inhabitants. The distinguishing feature of the institution is minimally invasive surgery.

The center was opened in 2011, under the auspices of the National Priority Project «Public Health». In 2012 it ranks the 2nd place for the neurosurgery operations over Russia after the Burdenko Neurosurgery Institute in Moscow.
