Fig. 7From: CT imaging-based histogram features for prediction of EGFR mutation status of bone metastases in patients with primary lung adenocarcinomaRepresentative histograms based on CT images. In the figure, the horizontal axis represents CT value, and the vertical axis represents the probability of which the corresponding CT value appears. a The histogram of a case showing EGFR positive expression; a 59-year-old woman diagnosed with primary lung adenocarcinoma that was confirmed as synchronous bone metastasis. The value of range was 1301.00. b The histogram of a case showing EGFR negative expression; a 67-year-old man diagnosed with primary lung adenocarcinoma that was confirmed as synchronous bone metastasis. The value of range was 312.00Back to article page
