Cone beam CT (CBCT) offers detailed 3D imaging of orbital anatomy and pathology. This technique is valuable for investigating osseous structures and certain orbital conditions, complementing other imaging modalities like CT and MRI.
Area of Science:
- Radiology
- Ophthalmology
- Medical Imaging
Background:
- Detailed orbital investigations benefit from 3-dimensional imaging.
- Computed tomography (CT) and cone beam CT (CBCT) allow easy visualization of orbital anatomy.
- Magnetic resonance imaging (MRI) is preferred for soft tissue evaluation, such as tumors and inflammation.
Purpose of the Study:
- To discuss the utility of CBCT in orbital imaging.
- To review the osseous anatomy of the orbits.
- To explore the application of CBCT in investigating orbital pathosis.
Main Methods:
- Routine and customized protocols for CT and CBCT scans.
- 3-dimensional imaging methods for detailed orbital investigations.
- Comparison of CT, MRI, and CBCT for specific orbital evaluations.
Main Results:
- CBCT provides high-resolution data of sinonasal spaces, airway, soft tissues, and bones.
- CT excels in visualizing osseous orbital anatomy and fissures.
- CBCT offers valuable insights into orbital pathosis, particularly for bony structures.
Conclusions:
- CBCT is a valuable tool for orbital imaging, especially for osseous structures.
- The choice of imaging modality (CT, MRI, CBCT) depends on the specific clinical question.
- CBCT complements CT and MRI in the comprehensive evaluation of orbital conditions.

Computed Tomography
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...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
