In Griffin 2025 et al., on SLN mapping with ICG, what was the histologic diagnosis of the pulmonary mass?
A. Grade 2 adenocarcinoma
B. Grade 1 adenocarcinoma
C. Carcinosarcoma
D. Primary lymphoma
E. Pulmonary histiocytosis
Answer: Grade 1 adenocarcinoma
Explanation: Histopathology confirmed a completely excised grade 1 pulmonary adenocarcinoma.
In Griffin 2025 et al., on SLN mapping with ICG, which lymph node was identified as sentinel?
A. Cranial mediastinal
B. Right tracheobronchial
C. Left tracheobronchial
D. Central mediastinal
E. Sternal
Answer: Right tracheobronchial
Explanation: NIR imaging localized the right tracheobronchial lymph node as sentinel after ICG injection.
In Griffin 2025 et al., on SLN mapping with ICG, what imaging modality was used to visualize lymphatic drainage?
A. CT-lymphography
B. Ultrasound
C. Near-infrared (NIR) imaging
D. MRI
E. Lymphoscintigraphy
Answer: Near-infrared (NIR) imaging
Explanation: NIR overlay was used intraoperatively to track lymphatic flow and identify the SLN.
In Griffin 2025 et al., on SLN mapping with ICG, how was indocyanine green administered?
A. IV bolus
B. Subcutaneous injection
C. Bronchoscopic instillation
D. Peritumoral injection under thoracoscopic guidance
E. Intranasal drip
Answer: Peritumoral injection under thoracoscopic guidance
Explanation: ICG was injected with a 22G needle into tissue adjacent to the mass thoracoscopically.
In Griffin 2025 et al., on SLN mapping with ICG, which statement best describes the clinical utility of this technique?
A. Applicable only to open surgery
B. Not feasible in dogs
C. Effective in identifying SLNs for staging
D. Poor visualization of lymphatics
E. Only useful for abdominal tumors
Answer: Effective in identifying SLNs for staging
Explanation: The method enabled safe, image-guided SLN extirpation during pulmonary surgery.
