Study on Improved Computed Tomography Scanning Parameters for Patients with Nasal Bone Fracture Based on ITK...

Area of Science:

• Medical Imaging
• Radiology
• Computed Tomography

Background:

• Nasal bone fractures require high-resolution imaging for accurate diagnosis.
• Conventional multi-slice spiral computed tomography (MSCT) parameters may limit image quality for subtle fractures.

Purpose of the Study:

• To evaluate the impact of optimized exposure parameters on MSCT image quality for nasal bone fracture assessment.
• To compare image quality between optimized and routine scanning parameters in nasal bone imaging.

Main Methods:

• A modified group (50 patients) received optimized MSCT parameters with coronal scanning.
• A routine group (50 patients) underwent standard scanning parameters.
• Image quality and nasal bone display were statistically analyzed and compared.

Main Results:

• Optimized parameters resulted in superior image quality compared to conventional parameters.
• Specific optimized parameters included 120 kv, 180 mA, 0.625 mm slice thickness, and 0.312 mm spacing.
• Clearer scanned images were achieved, validating the parameter optimization.

Conclusions:

• Optimized MSCT parameters and coronal plane imaging provide comprehensive visualization of nasal bones and surrounding structures.
• This approach offers high diagnostic value for nasal bone fractures.
• Standardized 3D annotation data based on ITK (Image Tool Kit) is established for future AI modeling.
