The Position and Configuration of the Anterior Mediastinum in Normal Volunteers / 实用放射学杂志

ABSTRACT

Objective To investigate the normal position and configuration of anterior mediastinum.Methods Chest CT scanning was performed in 100 healthy volunteers. Various parameters of the anterior mediastinum were measured, including position (shift distance from medial line of the body),frontal and retral width, and anterioposterior dimension.Results The normal range (with the limit of 95%) of the anterior mediastinum included the position was shifted 5 mm to right and 15 mm to left, the frontal width was under 30 mm in both man and woman, the posterior width was under 40 mm in woman, and under 50 mm in man, the anterioposterior diameter was under 30 mm in woman and under 35 mm in man.Conclusion The normal region about position and configuration of the anterior mediastinum is established in this study. These data will helpful in detecting the subtle mediastinal shift or other abnormal situation affected the mediastinum.
