A female patient arrived at the endoscopy center 2 days before her scheduled interventional bronchoscopy to receive an injection of a photosensitive intravenous dye that the pulmonologist explained would highlight the dysplastic tissues of her bronchi that were precancerous.He scheduled her for an ablative procedure called photodynamic therapy (PDT),where the highlighted tissues would be affected by the laser light that is color-specific for uptake of the dye.Select the laser tissue interaction that describes the patient's treatment.

Question

Quizplus · Accepted Answer

Absorption of laser light results when tissue is altered from the absorption of the beam.As the amount of energy delivered to tissue (fluence)increases,different tissue effects can be produced.The lowest level of energy produces a photochemical reaction.Then as fluence increases,a photothermal reaction occurs.With the highest level of fluence,a photoacoustic effect occurs.
