The new imaging methods (ultrasonography, CT, and MRI) 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.
Diagnostic images may be in black & white but they are very complicated and require years of study, experience and skill for accurate interpretation. A small shadow or increased density should be of major significance.
Radiologists specialize in diagnosing disease by using medical imaging studies such as:
- Computerized Tomography (CT or CTA)
- Magnetical Resonance (MRI)
The disease may be very complicated to diagnose correctly. Fortunately the patient and the doctor have the benefit of modern medical imaging technology.
The use of the medical imaging study help doctors to understand the medical condition of the patient better before treating them. The imaging study is interpreted by a radiologist who gives a diagnostic opinion in the form of a written report. Today's diagnostic radiologist in the United States complete four years of college, four years of medical school, a year of internship, four years of radiology residency and up to 2 years of fellowship training. This training includes medical image production, interpretation, radiation safety, and image-guided percutaneous intervention.
