Abstract

|
Recently, despite the spectacular development of imaging technology, the value of radiologic imaging in the asthma is still relatively underestimated compared to the other diseases. Because there are no specific imaging findings of asthma, the use of high-resolution compounded tomography (HRCT) in asthma is mainly implemented to assess complications and distinguish from other diseases. Common findings of HRCT in asthma patients include bronchial wall thickening, expiratory air trapping, cyclical bronchial dilation, airway narrowing, and mucoid impaction. Conversely, conventional magnetic resonance imaging (MRI) has many limitations in diagnosis of lung, so methods of MRI scan with inhaling special gases are being used for asthma, typically hyperpolarized MRI and oxygen-enhanced MRI. Although there is no proven imaging technology for diagnosis and monitoring of asthma to date, attempts to increase objectivity, reproducibility and accuracy continue to achieve them, there is a possibility of replacing traditional pulmonary function test in the future.
