Nasal obstruction (NO) is a common symptom caused by various nasal issues. This review details how imaging, including CT and MRI, helps diagnose the anatomical and pathological causes of NO for better treatment.
Area of Science:
- Radiology
- Otolaryngology
- Medical Imaging
Background:
- Nasal obstruction (NO) is a frequent clinical complaint indicating reduced nasal airflow.
- Causes of NO are diverse, including anatomical changes, inflammation, and tumors.
- Accurate diagnosis relies on understanding nasal anatomy and pathology.
Purpose of the Study:
- To review the normal anatomy of the nasal cavity and paranasal sinuses.
- To describe common conditions causing nasal obstruction.
- To illustrate the utility of CT and MRI in diagnosing nasal obstruction causes.
Main Methods:
- Review of imaging modalities, primarily Computed Tomography (CT) and Magnetic Resonance Imaging (MRI).
- Analysis of anatomical variations and pathological conditions affecting the nasal cavity and sinuses.
- Correlation of imaging findings with clinical symptoms of nasal obstruction.
Main Results:
- CT is the primary tool for evaluating nasal and sinus structures and abnormalities.
- MRI provides essential soft tissue characterization when needed.
- Various conditions, including tumors, inflammatory diseases, and anatomical variants, were identified on imaging.
Conclusions:
- Imaging, especially CT and MRI, is crucial for diagnosing the underlying causes of nasal obstruction.
- Understanding imaging presentations of nasal and sinus conditions aids in effective patient management.
- This review provides a guide to interpreting imaging for nasal obstruction.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
