Three-dimensional imaging for evaluation of head and neck tumors
1Department of Otolaryngology and Bronchoesophagology, Rush Medical College, Rush-Presbyterian-St Luke's Medical Center, Chicago, IL 60612.
Objective:
To determine the usefulness of three-dimensional imaging in addition to computed tomography in presurgical examination of patients with head and neck tumors.
Design:
Two-dimensional computed tomographic information from 31 patients with oral facial tumors was converted to three-dimensional images.
Setting:
University teaching hospital.
Patients Or Other Participants:
A consecutive sample of 31 patients with oral facial tumors.
Interventions:
None.
Main Outcome Measures:
Improved treatment planning with the use of three-dimensional images used in conjunction with computed tomographic scans.
Results:
The three-dimensional images from patients with minimal tumor invasion of bone or with massive soft-tissue tumors allowed easy appreciation of tumor dimensions, an important factor in treatment planning. In patients with small soft-tissue tumors with no evidence of bone involvement on two-dimensional scans, massive tumors with complete bone destruction, and recurrent tumors, the three-dimensional representations added little to the obvious presentation of the two-dimensional scans.
Conclusions:
Three-dimensional imaging is a useful adjunct to diagnosis and treatment planning in patients with minimal tumor invasion of bone or with massive soft-tissue tumors.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
