1Department of Radiology, First Affiliated Hospital, Sun Yat-sen University of Medical Sciences, Guangzhou 510080.
Objective:
To evaluate the clinical application of CT virtual endoscopy in larynx.
Methods:
The virtual endoscopy images were compared with that of actual laryngoscopy in 16 patients(4 normal larynx, 9 laryngeal carcinomas, 1 bilateral glottic polyps, one laryngeal fibrous hyperplasis and 1 airway striction caused by infiltration of the laryngeal carcinoma after laryngectomy). All the lesions were pathologically proved.
Results:
CT virtual endoscopy showed the normal anatomical structure of larynx as actual laryngoscopy. The location and extension of the lesions of larynx showed in CT virtual endoscopy agreed with that of actual laryngoscopy. In addition, CT virtual laryngoscopy revealed the structure of subglottic region and distal portion of strictured airway from feet to head, which were not available in actual laryngoscopy.
Conclusion:
CT virtual laryngoscopy is a good complemental method of fiber optic laryngoscopy.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
