Laser Ablation and Intravital Microscopy to Study Intestinal Remodeling

Laser Ablation and Intravital Microscopy to Study Intestinal Remodeling

Here, we present a method to obtain images of the intestine upon laser-induced wounding. By exposing the mouse intestine to a multiphoton laser, the loss of a single or multiple crypt(s) is induced locally. By repeatedly imaging the damaged area over months, the real-time dynamics of intestinal recovery is...

Focal Laser Ablation of Prostate Cancer: An Office Procedure

Focal Laser Ablation of Prostate Cancer: An Office Procedure

This article presents and describes an outpatient treatment for prostate cancer using focal laser ablation. Laser catheter placement is guided by MRI-ultrasound fusion imaging in a fashion similar to prostate needle biopsy. Treatment is monitored in real-time with a thermal probe, placed adjacent to the laser fiber.
