Abstract
In patients with oesophageal carcinoma being considered for esophagectomy, conventional staging methods include upper endoscopic gastroduodenoscopy, endoscopic ultrasonography(US), and computed tomography (CT) of the thorax and abdomen. The routine use of integrated positron emission tomography (PET)/CT with 2-[fluorine 18]fluoro-2-deoxy-d-glucose(FDG) in evaluation of patients with oesophageal carcinoma is increasing and has been reported to be useful in initial staging of oesophageal carcinoma. Methodology: This observational study retrospectively evaluated 45 consecutive patients with carcinoma esophagus which was diagnosed histologically. PET/CT is performed on an integrated scanner that combines both multisection CT and PET capabilities in two sequential gantries, avoiding the need for patient motion between the CT and PET components of the study and thereby leading to accurate coregistration of the CT and PET data. Results: In our study, 45 patients with histologically proven carcinoma esophagus were evaluated with PET-CT imaging which included 64.44% (no. 29) patients who had imaging only for staging, 31.11% (no. 14) patients for staging and response evaluation to therapy and 4.44% (no. 2) patients had treatment elsewhere and had PET-CT imaging for detection of recurrence of malignancy. Conclusion: appropriate and accurate interpretation of PET/CT results requires an appreciation of the artifacts and interpretative pitfalls that can be encountered in PET/ CT.
