Abstract
Background: The advent of multi-detector CT has revo-lutionized imaging of the airways and other thoracic structures. In comparison to single-detector helical CT scanners, mul-tidetector scanners not only provide faster speed, greater coverage, and improved spatial resolution, but also have the unique ability to create images of thick and thin collimation from the same data set. One of the greatest benefits of this new technology is the improved quality of two-dimensional (2D) multi-planar and three-dimensional (3D) reconstruction images. These images break away from the confines of the traditional axial imaging plane and have the potential to facilitate the assessment of a variety of airway disorders. With regard to the assessment of airway stenoses, multi-planar volume reformation methods aid in the detection of mild stenoses, improve the accuracy of determining the length of stenoses, and aid in the identification of horizontal webs. Review of multi-planar volume-reformatted images has been shown to aid in the planning of stent placement or surgery.
Multiple tracheal lesions can be assessed as tracheal stricture, Relapsing polychondritis, Amyloidosis, Tracheoma-lacia. Tracheopathia osteochondroplastica as well as saber-sheath trachea deformity.
Aim of the Work: The aim of our review study is to distinguish the features of different tracheal lesions using multi-detector CT.
Patients and Methods: This study included 20 patients; 15 males and 5 females, age range 8-83 (average of 46.67 years). Cases were referred from the ENT, Chest and Oncology Departments to Radiology Department in Kasr Al-Aini Hospital for MSCT Chest. The study was perfomed from March 2012 till March 2013. They were all subjected to Thorough clinical examination with history taking, general and chest examination, MSCT was done to all patients.
Results: In this study, we provide evidence that multislice computed tomography (MSCT) is able to diagnose different tracheal lesions either in symptomatizing patients or incidental in cases presenting with known or chronic illness or other clinical suspicion.
