Radiology

Radiology is the study of disease through imaging.

Diagnostic radiology is a medical specialty which was born shortly after the discovery of x-rays of Wilhelm Roentgen in 1895. The first radiologists were trained in the use of x-rays for both the diagnosis and the treatment of disease. During their first 50 or so years, diagnostic radiologist had only x-rays with which to produce medical images. The last 30 years have witnessed the development of the nuclear medicine: ultrasonography, CT scanning, and finally MRI. In the 1960's the specialty was divided into Diagnostic Radiology and Radiation Oncology (radiation therapy).

These new imaging methods permit doctors to visualize regions of the body previously accessible only through exploratory surgery. They have given birth to a new subspecialty: interventional radiology (image-guided percutaneous biopsy and intervention). Some radiology departments are now called Diagnostic Imaging.
