title: [Computed tomographic densitometry in the diagnosis of chronic obstructive lung diseases].
abstract: The capacities of spiral computed tomography (CT) synchronized with a patient's respiration in the diagnosis of chronic obstructive lung diseases (COLD) were studied. Normal lung parenchymal density was clarified in different parts. The densitometric changes typical of bronchial asthma (BA) and COLD were studied in relation to the severity of an obstructive process. The differential diagnostic criteria of BA and COLD, including those at the early stage of the disease, are proposed. The optimized procedure of spiral CT synchronized with the patient's respiration is presented.
