Официальное название
A Prospective, Multi-Center, Assessor-Blinded Study on the Clinical Efficacy of CCeLL-In Vivo (Confocal Fluorescence Endomicroscopy) for Intraoperative Brain Tumor Diagnosis.
Обзор
The primary objective of this study is to demonstrate the non-inferiority of cCeLL compared to frozen section analysis. The investigational device is intended for use with indocyanine green (ICG) for fluorescence imaging as an aid in the visualization of vessels (micro- and macro-vasculature) blood flow in the cerebrovascular before, during or after cranial diagnostic and therapeutic procedures, such as tumor biopsy and resection, which is then read and analyzed by trained-professional for intraoperative diagnosis. The comparison will be held by the device with the conventional intraoperative histological frozen section analysis of identical brain tissue samples in the same patient. Both methods will be compared in terms of their accuracy using the standard of practice, the final pathological diagnosis.
