Modalities
|
The use of CT in Asthmatics mainly involves High Resolution CT (HRCT) technique. Most often this low dose technique allows quantification of airway wall dimensions such as wall thickness and wall area percentage. The HRCT technique is applied to specific segments or branches of the airway tree (such as RB1) for visual or semi-automatic quantification. |
