Experimental: cCeLL - In vivo Imaging
Participants diagnosed with brain tumors will receive an intravenous injection of Indocyanine Green (ICG) during surgery.
The cCeLL - In vivo confocal laser fluorescence microscope will be used to capture real-time images of the tumor margins before tissue collection.
Standard frozen section and permanent section analyses will then be performed for diagnostic comparison.
|
Dosage Form: Intravenous injection Dosage: 0.1 - 0.5 mg/kg of Indocyanine Green (ICG) Frequency: Single administration during surgery Duration: Real-time imaging performed immediately after ICG injection and used intraoperatively for tumor margin assessment

Measure Description |
Time Frame |
|---|---|---|
|
Non-Inferiority of Diagnostic Accuracy (Percentage of Correct Normal/Tumor Classifications) of cCeLL Compared to Frozen Biopsy
Time Frame: Visit 1 (Surgery Day / Intervention Day) as D-Day
|
The diagnostic accuracy of cCeLL-In vivo will be assessed by measuring the percentage of correct normal/tumor classifications compared to the reference standard frozen biopsy.
Non-inferiority will be determined using pre-specified statistical margins for sensitivity and specificity.

|
Diagnostic Accuracy, Sensitivity, and Specificity of cCeLL Compared to Frozen Biopsy Across Tumor Types and Locations
Time Frame: Visit 1 (Surgery Day / Intervention Day) as D-Day
|
The diagnostic performance of cCeLL-In vivo will be evaluated by calculating accuracy (percentage of correct diagnoses), sensitivity, and specificity across various tumor types and locations.
These values will be compared to those obtained using frozen biopsy as the reference standard.

Percentage of Non-Diagnostic Samples in cCeLL Imaging
Time Frame: Visit 1 (Surgery Day / Intervention Day) as D-Day
|
The percentage of non-diagnostic samples (images that cannot be used for a definitive diagnosis) obtained using cCeLL-In vivo will be recorded.
A lower rate of non-diagnostic samples would indicate higher image usability and reliability.

Time (Minutes) Required to Obtain a Diagnosis Using cCeLL-In vivo vs. Frozen Biopsy Description:
Time Frame: Visit 1 (Surgery Day / Intervention Day) as D-Day
|
The time required to obtain a definitive diagnosis will be measured in minutes, from the point of sample collection to the final diagnostic decision.
The average diagnostic time for cCeLL-In vivo will be compared to the traditional frozen biopsy method to evaluate potential time efficiency improvements.

Inter-Observer Agreement (Cohen's Kappa Score) Between Two Pathologists Using cCeLL-In vivo Images
Time Frame: Visit 1 (Surgery Day / Intervention Day) as D-Day
|
The level of agreement between two independent pathologists interpreting cCeLL-In vivo images will be measured using Cohen's kappa coefficient (κ).
The kappa score will quantify inter-observer agreement beyond chance, with values ranging from 0 (no agreement) to 1 (perfect agreement).

Diagnostic Accuracy (Percentage of Correct Tumor Classifications) of AI-Based Brain Tumor Diagnosis Using cCeLL-In vivo Images
Time Frame: Visit 1 (Surgery Day / Intervention Day) as D-Day
|
The accuracy of AI-based diagnosis will be measured as the percentage of correct tumor classifications (normal vs. tumor) compared to the reference standard diagnosis made by expert pathologists.
Sensitivity, specificity, and overall accuracy will be calculated to evaluate AI performance.
