Abstract
Diagnostic imaging is an important way in clinical diagnosis of Influenza A(H1N1). Studies found that imaging demonstrations of Influenza A(H1N1) can be shown in its critical period. MRI of the nerves system demonstrates flaky long T2WI signals, with symmetrical cerebral white matter lesions; diagnostic imaging of the respiratory system demonstrates flaky shadows or parenchymal shadows, especially in the posterior basal segments of both lower lungs. The pulmonary infiltration can quickly develop into parenchymal changes, with occurrence of diffusive ground glass liked shadows or pulmonary parenchymal shadows in both lungs in a short period of time. Sometimes, it may cause complications like general organs failure. Diagnostic imaging findings of Influenza A(H1N1) are usually characteristic but not specific. And it should be differentiated in the diagnosis from HIV encephalopathy, heroin encephalopathy and ateriosclerotic encephalopathy. The commonly occurred critical Influenza A(H1N1) should be differentiated in the diagnosis from influenza, common cold, bacterial pneumonia, severe acute respiratory syndrome (SARS), chlamydial pneumonia and mycoplasma pneumonia.
