Overview
Other diagnostic studies for esophageal cancer include FDG-PET (positron emission tomography) scan and endoscopic ultrasound (EUS).
Other Diagnostic Studies
Fludeoxyglucose Positive Emission Tomography
FDG-PET (positron emission tomography) scan is also being used to estimate whether enlarged masses are metabolically active, indicating faster-growing cells that might be expected in cancer. Esophageal endoscopic ultrasound (EUS) can provide staging information regarding the level of tumor invasion, and possible spread to regional lymph nodes.[1]>[2]
Esophageal Ultrasound
EUS is the most accurate investigation for regional staging of esophageal cancer. It is capable of correctly staging T and N stagesin 90% of patients.[3]
