Blood perfusion studies on basal cell carcinomas in conjunction with photodynamic therapy and cryotherapy employing laser-Doppler perfusion imaging
Superficial blood perfusion mas monitored using laser-Doppler perfusion imaging in connection with a phase LII clinical trial comparing photodynamic therapy, utilizing topically applied aminoleuvlinic acid, with cryotherapy of basal cell, carcinomas. A total of 526 images mere recorded before and immediately after the treatment and during the follow-up period. Before treatment, the lesions exhibit
