Radiological application of three-dimensional imaging systems.

Three-dimensional displays are becoming more frequent in medical imaging. As PACS and imaging workstations as nodes on networks provide greater ease and availability of three-dimensional reconstructions of digital data applications are increasing. Applications at this time are limited to high-contrast structures. In CT these are complex fractures or deformities. Three-dimensional display clarifies the anatomy and facilitates operative planning. In MRI, MR angiography is the principal application. The ability to rotate the data set in three dimensions eliminates potential overlap, increasing the sensitivity and specificity of the technique. Three-dimensional imaging is becoming available for scintigraphic and sonographic studies but applications have not yet been clarified.
