Which diagnostic imaging modality will provide greatest tissue resolution, allowing for better characterization of bronchiectasis?

Question

Quizplus · Accepted Answer

Computed tomography (CT) is the best choice for imaging bronchiectasis as it provides high-resolution images of the lungs and airways, allowing for better characterization of the abnormal dilatation of the bronchi seen in bronchiectasis. CT also allows for the identification of associated findings such as mucus plugging, air trapping, and bronchial wall thickening. Ventilation/perfusion scans may be helpful in assessing pulmonary function and detecting pulmonary embolism, but are not specific for bronchiectasis. Magnetic resonance imaging (MRI) may provide high-resolution images but is not commonly used in the evaluation of bronchiectasis. Conventional tomography is an older imaging technique that is no longer commonly used due to its limited diagnostic yields and high radiation doses.
