obstructed. A head CT scan is also used to investigate jaws, sinuses (the hollow air-filled spaces around the nose) for infections such as sinusitis. People suffering from frequent dizziness, chronic headaches, or neurological disorders such as seizures may also be advised to undergo a CT head...
The advent of 3D navigation imaging has opened new borders to the endoscopic surgical approaches of naso-sinusal inflammatory and neoplastic disease. This technology has gained in popularity among otolaryngologists for endoscopic sinus and skull base surgeries in both adults and children. However, the...

In patients with renal cell carcinoma (RCC), the presence of an unsmooth margin or a finger-like protrusion is a CT-based tumor feature that can be used to predict pathologic renal sinus invasion (RSI) preoperatively [38]. These two studies suggest that tumor margin morphology has the ...
