One of the first methods discovered to create photographic images of internal body structures utilized an X-ray beam and a photosensitive plate (film). The beam passed through the body structure of interest and left an image on the film. The images on film came to be called X-rays or radiographs. Departments that created and interpreted these film images became known as X-ray Departments or Radiology Departments.

We now have many different ways to image internal structures. In addition to X-rays, we also use sound waves, magnetic fields and other methods to create images. The marriage of these imaging technologies with computers has given us powerful tools to look inside the body.

Following are descriptions of the most common imaging procedures currently in use. Some can be performed in the ICU without moving the patient; others require transfer of the patient to the Radiology Department. If you have further questions after you have read this section, please consult your doctor or nurse or call us for a personal consultation.
