Summary
Imaging paranasal sinuses and nasal cavity aids in evaluating suspected neoplasia. Computed tomography (CT) and magnetic resonance imaging (MRI) offer detailed anatomical insights for disease assessment.
Area of Science:
- Radiology
- Medical Imaging
Background:
- Imaging is crucial for assessing paranasal sinus and nasal cavity neoplasia.
- Conventional films, CT, and MRI are primary imaging modalities.
Purpose of the Study:
- To outline the role of different imaging modalities in evaluating suspected neoplasia of the paranasal sinuses and nasal cavity.
- To highlight the strengths of each imaging technique.
Main Methods:
- Review of imaging modalities including plain films, CT, and MRI.
- Discussion of their applications in neoplasia evaluation.
Main Results:
- Plain sinus films serve as the initial screening procedure.
- CT is preferred for detailed assessment of sinuses and nasal cavity.
- MRI is indicated for superior soft tissue contrast.
Conclusions:
- Imaging defines the extent of disease but does not diagnose malignancy.
- The choice of imaging modality depends on the clinical question and required information.
