Quantification of ALA-induced PpIX Fluorescence During Brain Tumor Resection
Removing a tumor from a patients brain is hard to do because, very often, brain tumors do not
have boundaries that are easy for the patients surgeon to find. In many cases, the surgeon
can't tell exactly where the tumor begins or ends. The surgeon usually can remove most of the
patient's tumor by looking at the MRI images that were taken of the patient's brain before
surgery. However, the surgeon does not have any good way to tell if the entire tumor has been
removed or not. Removing the entire tumor is very important because leaving tumor behind may
allow it to grow back which could decrease the chances of survival.

- Elevated liver function levels greater than 2.5 times the normal limit from laboratory
tests conducted within 30 days prior to surgery.
- Inability to comply with the photosensitivity precautions associated with the study.
