Diagnosing Cushing's disease is a multidisciplinary process involving doctors, endocrinologists, radiologists, surgeons, and chemical pathologists. These include radiographers, radiologists, Sonographers, medical laboratory scientists, pathologists, and related professionals. Historically performed by interventional radiologists, vascular surgeons have become increasingly proficient with endovascular methods. They are commonly placed by surgeons or interventional radiologists. Radiologists and radiographers are among the earliest occupational groups exposed to radiation. The front-runners of minimally invasive procedures were interventional radiologists. More recently, interventional radiologists have started treating venous problems. The field was originally pioneered by interventional radiologists, chiefly Dr. Charles Dotter, who invented angioplasty. The least invasive and most effective form of treatment is now performed by interventional radiologists. Ophthalmologists and radiologists earned more than $445,468 per year. For example, Raymonds were more likely to be radiologists than dermatologists. Radiological anatomy is a necessary component of training for radiologists as well as medical students. Radiologists and medical physicists wanted to use the images for dose-planning for radiation therapy. Lawyers, radiologists and software designers have seen their work outsourced to the developing world. The principles of PACS were first discussed at meetings of radiologists in 1982.
