Abstract
The purpose of this prospective observational study was the evaluation of the usefulness of MPR reconstructions and virtual endoscopy in the study of the esophageal carcinoma. Thirty-nine patients with esophageal cancer proved by means of endoscopy, underwent preoperative TNM staging with dynamic CT of the chest and abdomen with the aid of 3D rendering. Twenty-six patients underwent surgery, and the CT results were compared with histopathologic findings. In staging the T parameter, the CT with 3D reconstructions and virtual endoscopy, showed a sensitivity of 92% and an accuracy of 88%. In staging lymph nodes, the sensitivity in our study was 85%, the specificity 58%, and the accuracy 69%. Our protocol of the study of the esophageal cancer with 3D CT and virtual endoscopy, demonstrated a high concordance with the surgical and pathologic findings. The 3D reconstructed images were very helpful to the surgeons regarding preoperative planning. We performed an observational enquiry, and although this was a small study, it has, however, confirmed that the 3D imaging of the esophagus represents a valuable advantage to conventional imaging. Further studies with a larger number of patients are needed to prove its superiority to traditional CT imaging of the esophagus.
