Correlation between CT Score and KL-6: A Severity Assessing in Juvenile Dermatomyositis Associated Interstitial Lung Disease

Figure 1

A 9-year-old girl of JDM-ILD. The KL-6 value was 3949 U/ml. The level of pulmonary vein and 1 cm above carina divide the lungs into upper, middle, and lower parts. The right lung was marked from top to bottom as Zone A to C. The left lung was marked from top to bottom as Zone D to F. The score of each zone was equal to image pattern points multiplied by distribution range points. Zone A score = 3 × 2, Zone B score = 3 × 3, Zone C score = 3 × 3, Zone D score = 3 × 2, Zone E score = 3 × 2, and Zone F score = 3 × 2. Total CT score = 42.
