Can a CT PNS Scan Detect Chronic Sinusitis? A CT PNS scan can help doctors detect and evaluate chronic sinusitis by providing detailed images of the paranasal sinuses. It may reveal sinus inflammation, mucosal thickening, mucus build-up, blocked drainage pathways, nasal polyps and structural abnormalities that could contribute to persistent symptoms. Doctors may recommend CT PNS when nasal congestion, facial pressure, headaches or sinus problems continue despite treatment or repeatedly return. The scan is quick and is commonly performed without contrast, depending on clinical requirements.
