Advanced computer applications in radiology: clinical applications.
Computers play a major role in bridging the gap between image generation and patient care by providing enhanced images that better meet the needs of referring physicians. Spiral computed tomography allows generation of three-dimensional images that are not affected by motion artifact. Volume rendering, a three-dimensional reconstruction algorithm, yields images free of computer-generated artifacts and superior in quality. Currently, technologic computer advances play an important role in three clinical areas: orthopedic applications, oncologic applications, and prosthetic design. Three-dimensional imaging is especially valuable in fracture assessment because it allows exploration of image data to define the location of fracture fragments, the integrity of the joint space, and any possible displacement. With three-dimensional imaging, the extent of tumor spread into adjacent soft tissue or involvement of blood vessels can be determined, even in difficult anatomic areas. Volume rendering and increased computer speed allow greatly improved treatment planning for radiation therapy and custom design of orthopedic prostheses. Through the mutual understanding of goals between physicians and computer scientists, the computer can reach its full potential in medicine, resulting in improved patient care.
