| Objective To set up the character and the diameter of distribution of the pulmonary small vessels within inner and mid part of CT images of the lung in normal individuals. Methods Images of lung CT in 180 normal adults were selected and divided into three groups according to the sex and age. Six slices with apparent anatomical signs were selected from each image and marked out the inner and mid parts, the diameters and number of small vessels in each part were measured and analyzed. Results The normal range of the diameter and number of pulmonary small vessels in each slice were obtained. The affect of sex and age to the diameter and number of pulmonary small vessels was found. Conclusion The diameter and number range of pulmonary small vessels within inner and mid part of CT images of the lung in different sex and age of normal adults has its own rules. |
