Radiologic Imaging of Nasal Polyposis
摘要
Radiology plays several crucial roles in the evaluation of chronic rhinosinusitis patients with nasal polyposis, including establishing the diagnosis, evaluating disease progression or response, surgical planning, and monitoring for recurrence. Computed tomography (CT) is the primary modality used to evaluate patients with nasal polyposis (NP), but magnetic resonance (MR) does play an occasional role. This chapter reviews the radiologic appearance of sinonasal polyps and their complications, and also discusses the radiologic differential diagnosis.
