The following are examples of some of the applications of 3D imaging for various medical and surgical specialties.

Neurology/Neurosurgery
Three-dimensional visualization of cerebral vasculature from CT angiography provides increased confidence in planning surgical intervention in life-threatening aneurysm cases. 3D views of MRI cortical surface and underlying tissues, with optional functional MRI fused with 3D anatomical display, enables neurosurgeons to plan procedures to spare crucial cortical areas, improve patient care and reduce operating room time.

Orthopædics
For skeletal trauma, especially involving the face, spine, pelvis, acetabulae, foot, and shoulder girdle, three-dimensional visualization is extremely helpful for comprehensive understanding of the case and aids in assessment, decision making and surgical planning.

Vascular Surgery
Three-dimensional renderings, multiplanar, oblique and curved reconstruction help visualize CT and MR angiography for many vascular cases. Combining these views with quantitative measures helps accurately design aortic stent specifications.

GI/GU
3D viewing of CT or MR angiography is helpful in analyzing vascular involvement in tumors for difficult pancreatic, renal and biliary cases being considered for resection. New applications such as CT virtual colography and CT urography are currently under development for future routine clinical use.

Oral Maxillofacial Surgery
Visualizing the alveolar nerve canal on 3D CT and the lingual nerve on 3D MRI can help prevent nerve damage or assess nerve involvement from extractions. For maxillofacial cases, three-dimensional rendering can guide surgical planning and treatment.

Chest
Tracking the lumen of the trachea, lungs and bronchi and visualizing these passages with curved reconstructions or with virtual, intraluminal views helps visualize the anatomy. 3D also can help in the assessment of CTA of the lungs.
