Longitudinal_Tile_Dermoscopic

Here we present a dataset derived from two longitudinal studies on general (n=196) and high-risk populations (n=284). The dataset includes longitudinal images of pigmented lesions extracted from 3 Dimensional (3D) TBP (on average, 521 lesions per person), and corresponding dermoscopic images for lesions that were larger than 5 mm and lesions that were of interest by either the participant or clinician (on average, 20 lesions per person). This dataset overall includes images of 250,162 skin lesions. For 165,251 of these lesions, longitudinal low resolution images (including 28 melanomas) and for 7,779 of these lesions corresponding longitudinal dermoscopic images (including 19 melanomas) are available. This dataset of skin images is accompanied by comprehensive individual-level metadata on lesion anatomic location, individuals’ number of naevi, demographics, skin cancer history, freckling, as well as sun exposure and sun protection behaviour data.本研究公开了一项源自两项针对普通人群（n=196）与高风险人群（n=284）的纵向研究数据集。该数据集包含从三维（3D）TBP中提取的色素性皮损纵向影像（平均每人对应521处皮损），以及针对直径大于5mm的皮损、受试者或临床医师关注的皮损所对应的皮肤镜影像（平均每人对应20处皮损）。该数据集总计包含250162处皮肤皮损的影像数据。其中165251处皮损可获取纵向低分辨率影像（含28例黑色素瘤），另有7779处皮损可获取对应的纵向皮肤镜影像（含19例黑色素瘤）。该皮肤影像数据集配套包含全面的个体水平元数据，涵盖皮损解剖位置、个体痣的数量、人口统计学信息、皮肤癌病史、雀斑情况，以及日晒与防晒行为相关数据。
