TISSUE BLOOD-FLOW MAPPING

The operating principles of Laser Doppler Perfusion Imaging (LDPI) for visualization of the tissue blood perfusion are explained. Using this emerging technology skin perfusion has been investigated in healthy v olunteers and in patients with various conditions that affect skin blo od flow. LDPI is anticipated to be particularly useful in evaluation o f peripheral circulation in diabetics, as an objective tool in irritan cy patch testing, assessment of burnt skin and visualization of spot-w ise hyperperfusion in breast skin in association with carcinoma.
