电生物阻抗可用于评估皮肤癌和其他皮肤病变。本研究的目的是区分皮肤癌良性痣使用多频阻抗谱。本文测量了100例皮肤癌和511例良性痣的电阻抗谱。在病变同侧测量参考皮肤的阻抗。利用病变皮肤与参考皮肤的阻抗关系来区分癌和痣。结果发现，它是可能的，以75%的特异性和100%的灵敏度，从良性痣恶性黑色素瘤，并区分非黑色素瘤皮肤癌从良性痣87%的特异性和100%的灵敏度。使用电阻抗检测皮肤癌的能力与普通医生进行的常规视觉筛查一样好，甚至更好。
Electrical bio-impedance can be used to assess skin cancers and other cutaneous lesions. The aim of this study was to distinguish skin cancer from benign nevi using multifrequency impedance spectra. Electrical impedance spectra of about 100 skin cancers and 511 benign nevi were measured. Impedance of reference skin was measured ipsi-laterally to the lesions. The impedance relation between lesion and reference skin was used to distinguish the cancers from the nevi. It was found that it is possible to separate malignant melanoma from benign nevi with 75% specificity at 100% sensitivity, and to distinguish nonmelanoma skin cancer from benign nevi with 87% specificity at 100% sensitivity. The power of skin cancer detection using electrical impedance is as good as, or better than, conventional visual screening made by general practitioners.
