The various advantages of the intermediary world of sciences has been the development as well as invention of some of the most revolutionary instruments and technologies that have really given the world of sciences and technologies a great leap in every sense of the term. One such technique that is the result of such interdisciplinary endeavors and has been very helpful in diagnosing and treating variety of diseases that had been considered incurable or at least difficult to treat till date is the technique of radiology. The technique of radiology involves study as well as application of imaging technologies in order to diagnose as well as treat various diseases. Some of these imaging technologies that are used are computed tomography [http://www.radiology-info.org/computed-tomography.html] (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and ultra sound. 

 
There is another method of radiology known as the interventional radiology is the carrying out of medical techniques using minimal invasive techniques. The technical people who are responsible for carrying out the radiological techniques are known as radiologists or radiologic technologist. The technique of radiology has been the cornerstone of the medical procedures for more than a century now. The various imaging techniques that are used by the radiologists help them in the correct diagnosis as well as treatment of a variety of diseases. In particular these techniques have really proved to be very helpful in diagnosing as well as treating some of the most perilous diseases like cancer. 

 
Apart from getting the critically important images for the treatment of diseases, this technique can also be used to guide other medical techniques that are more invasive in nature. In many of the invasive treatment methods a careful guidance of the instruments is required through those areas of the body that are not easily visible. In procedures like angioplasty, and radiograms, imaging techniques like fluorescent markers, ultrasound, and MRI are used.
