Radiology represents a branch of medicine that deals with radiant energy in the diagnosis and treatment of diseases. This field can be divided into two broad areas – diagnostic radiology and interventional radiology. A physician who specializes in radiology is called radiologist.The outcome of an imaging study does not rely merely on the indication or the quality of its technical execution. Diagnostic radiology specialist represents the last link in the diagnostic chain, as they search for relevant image information to evaluate and finally support a sound diagnosis.
The fields of science, mathematics, medicine and philosophy were blossoming, and scientific societies were starting to publish their results to a growing international community of researchers. Even then Leibniz saw problems of confusion, mis-communication and inefficiency, and began dreaming of solutions. Today, we have powerful tools, beyond his imagination, but as fields like medicine have become increasingly globalized, we are faced with greater risks of ambiguity and miscommunication. Leibniz is remembered by mathematicians for inventing the calculus independently of Newton, and by readers of Voltaire for his argument that ours is the best of all possible worlds.
Numerous facilities in clinical services are collectively used by different specialties: operating rooms are not owned by surgeons anymore, ICUs have become independent of departments of cardiology, internal medicine, or neurology, while emergency rooms are not part of traumatology departments. Hospital beds are no longer dedicated to individual specialists or specialties and are available for radiologists for one or two nights following interventional procedures in some hospitals. At present the radiology department remains predominantly the domain of the radiologist, but this is changing and there is no specific reason why imaging facilities should not be used by other clinical specialists trained in imaging, and images produced in these departments may also be reported remotely.
Side effects can happen any time during, immediately after or a few days or weeks after radiation therapy. Most side effects generally go away within a few weeks to 2 months of finishing treatment. But some side effects may continue after treatment is over because it takes time for healthy cells to recover from the effects of radiation therapy. Late side effects can happen months or years after treatment. If doses of radiation are high enough, some cells may not be able to repair themselves. As a result, some side effects may last a long time or be permanent.
The rapid advances in clinical radiology technology and theory have dramatically improved the diagnosis and treatment of illness and injury.
The disadvantages of radiation therapy include:
