Findings in this study indicate that radiologist's interpretation accuracy in interpreting digital mammograms depends on lesion type. Interpretation accuracy was not influenced by the image-processing method.

In the past 5 years, computed tomography (CT) has been reported to be a valuable preoperative staging technique for patients with carcinoma of the esophagus and gastroesophageal junction [21][22][23][24][25][26][27][28][29]. Fewer than 200 patients have had accurate confirmation of preoperative CT findings [22][23][24][25][26][27][28]. In our initial experience with 30 patients using a second-generation CT scanner [23], there were a number of limitations: (1) Scan interpretation was performed with the knowledge that the patient had a known esophageal malignancy and in many cases known metastases; (2) no appraisal of the specific criteria used to deter mine local invasion or lymph node metastases was made; (3) not every patient underwent contiguous 1-cm scans of the entire thorax and upper abdomen; (4) not all patients received oral contrast material; and (5) not all CT findings were confirmed, as not every patient underwent surgical resection of the neoplasm.
