Abstract
Esophageal cancer is one of the common cancers. Risk factors are well recognized and
lead most commonly to two distinct histological subtypes (squamous cell carcinoma
and adenocarcinoma). The diagnosis is based on endoscopic evaluation. The most challenging
aspect of management is accurate staging as it guides appropriate management. Endoscopic
ultrasound, computed tomography (CT), positron emission tomography-CT, and magnetic
resonance imaging are the imaging tests employed for the staging. Each imaging test
has its own merits and demerits. Imaging is also critical to evaluate posttreatment
complication and for response assessment. In this review article, we discuss in detail
the risk factors, anatomical aspects, and role of imaging test in staging and evaluation
of complications and response after treatment.
