Abstract:
In esophageal cancer staging, the radiologic approach is represented by tumor identification, preoperative staging, and re-staging after neoadjuvant therapies. At present, while barium radiography shows a high sensitivity for early and advanced tumors, endoscopy is always necessary for confirmation. CT and MRI are the gold standard for preoperative staging of advanced (T4) esophageal cancer and for evaluation of distant metastasis; however they still show a low sensitivity in the study of possible regional lymph node involvement, in differentiating residual disease and scarring; in particular the esophageal wall cannot be carefully examined.

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...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
