Advances in diagnostic imaging techniques (e.g., computed tomographic [CT] scan and magnetic resonance imaging [MRI]) have enhanced the understanding and management of sinusitis. It can even generate three-dimensional images. CT imaging allows providers to have a more in-depth look at your sinuses to determine the cause of blockages.
