Clinical Question:
What is the sensitivity and specificity of 18F-fludeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) imaging for detecting mediastinal lymph node involvement in patients with potentially resectable non-small cell lung cancer (NSCLC)?
Bottom Line:
Sensitivity and specificity of FDG-PET/CT imaging ranged from 0.77 to 0.81 for sensitivity and 0.79 to 0.90 for specificity, and were related to the brand of scanner, NSCLC subtype, FDG dose, and country of study origin. These sensitivities and specificities are not sufficiently accurate to warrant reliance on FDG-PET/CT scanning alone to make decisions about surgery as a single option for patients with potentially resectable NSCLC. Instead FDG-PET/CT imaging should be used to determine whether the next step should be biopsy (endobronchial ultrasound-guided biopsy or mediastinoscopy) or surgical resection.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
