Abstract:
High-resolution computed tomography (HRCT) is now widely used in the investigation of patients with suspected or known diffuse lung disease. This article reviews some of the technical aspects of HRCT and the pathologic considerations that should be appreciated in the context of diagnosing fibrosing alveolitis. The precise quantitation of disease extent and characterization of disease pattern on HRCT has been used to provide new insights about the prognosis and pathophysiology of fibrosing lung disease.

Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Description
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...
