Abstract:
We report a case of asymptomatic bronchial atresia of the anterobasal and laterobasal segments of the right lower lobe. Because of the absence of typical bronchial mucocele on chest radiograph, it was difficult to base the diagnosis on chest radiography alone. Helical CT images demonstrated the characteristic appearance of bronchial atresia, and three-dimensional (3D) CT bronchography using the volume rendering technique helped us to comprehend the spatial relationship between the dilated bronchus distal to the atresia and the more proximal bronchus.

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
