[Imaging of paranasal sinuses today]

Area of Science:

• Radiology
• Medical Imaging

Background:

• Computed tomography (CT) is the gold standard for evaluating paranasal sinus diseases.
• CT scans are essential for surgical planning in paranasal sinus conditions.
• Common indications include chronic sinusitis, trauma, and malignant diseases.

Purpose of the Study:

• To evaluate methods for reducing radiation dose in paranasal sinus CT scans.
• To compare the effectiveness of low-dose CT with standard techniques.

Main Methods:

• Utilizing a low-dose spiral CT technique.
• Reforming coronal images from axial CT data, avoiding direct coronal scans.

Main Results:

• Effective dose of paranasal sinus CT can be reduced to the level of a chest radiogram.
• Low-dose technique maintains diagnostic quality for paranasal sinus evaluation.

Conclusions:

• Low-dose CT is a safe and effective imaging modality for paranasal sinus disease.
• Radiation dose reduction is important due to the benign nature of most conditions and patient demographics.
