Description
A sinus CT scan precisely images nasal and sinus structures to diagnose chronic sinusitis, polyps, or infections; in China, it typically costs ¥200–500, with ChinaMedicalHub assisting with hospital booking and interpreter support.
Main Uses
Sinus CT scans are primarily used for diagnosing and evaluating conditions affecting the paranasal sinuses. They are particularly useful in cases of suspected sinusitis, to assess the extent of disease, plan surgical interventions, evaluate postoperative changes, and diagnose structural abnormalities or tumors. Sinus CTs are also valuable in guiding treatment decisions and monitoring response to therapy.
Normal Range
A normal sinus CT scan shows clear, well-aerated sinuses without evidence of mucosal thickening, polyps, or fluid. The bony structures should appear intact and there should be no signs of inflammation, infection, or tumors.
Low Values - Possible Causes
Low values or findings on a sinus CT are not typically described in terms of numerical values but rather in the absence of abnormal findings. However, if referring to under-diagnosis or missed conditions, common reasons could include: inadequate imaging technique, early stage of disease, patient movement during the scan, misinterpretation of results, or very subtle pathology that is difficult to detect.
High Values - Possible Causes
High values or abnormal findings on a sinus CT can indicate: acute or chronic sinusitis, nasal polyps, fungal infections, tumors (benign or malignant), or structural abnormalities such as deviated septum or concha bullosa. These findings suggest the presence of inflammation, obstruction, or other pathological processes within the sinuses.
