Fig. 4From: Deep learning radiomics of dual-modality ultrasound images for hierarchical diagnosis of unexplained cervical lymphadenopathyExamples of heatmaps generated by CLA-HDM for each etiology of unexplained CLA. When ultrasound BUS and CDFI images of a case (first row) are input into CLA-HDM, it will firstly give first-level diagnostic heatmaps to distinguish benign from malignant CLA (second row) and then second-level diagnostic heatmaps to identify the specific etiologies of benign or malignant CLA (third row). Generally, the heatmaps reveals a corresponding regularity for each pathology category. CLA, cervical lymphadenopathy; BUS, B-mode ultrasound; CDFI, color Doppler flow imagingBack to article page
