Head and neck tumors, MRI versus CT: a technology assessment pilot study

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Magnetic resonance imaging (MRI) and high-resolution computed tomography (HRCT) are established methods for evaluating head and neck tumors.
• Limited comparative data exists on the relative diagnostic and therapeutic utility of MRI versus HRCT in this patient population.

Purpose of the Study:

• To assess the comparative diagnostic and therapeutic value of MRI and HRCT in patients with head and neck tumors.
• To determine how often each modality provides valuable information influencing patient management.

Main Methods:

• Thirty-three patients with head and neck tumors underwent both MRI and HRCT.
• Diagnostic and therapeutic values were classified, assessing information utility and impact on patient management.
• Outcomes were categorized based on the quality of information provided, from confusing to unique, and treatment impact, from disadvantageous to favorable.

Main Results:

• MRI demonstrated 100% positive diagnostic and therapeutic results for benign tumors in 14 patients.
• For 19 malignancies, MRI yielded positive diagnostic and therapeutic results in 84% of cases.
• MRI positively influenced therapeutic management in 91% of examinations, though CT is preferred for suspected skull base infiltration.

Conclusions:

• MRI is the preferred imaging modality for head and neck neoplasms, offering significant diagnostic and therapeutic benefits for treatment planning and follow-up.
• While MRI excels in evaluating most head and neck tumors, HRCT remains crucial when skull base infiltration is suspected.
• MRI provides essential information supporting the diagnosis of head and neck diseases.
