“…CT, however, has the potential for providing further information about the site of involvement and the extent of diseases such as cancer. However, CT is not utilized widely for this purpose, and thus far only a few reports have been published [1,4,5,7,8,13,15,16]. Our search of the available literature revealed no reports of the use of CT to detect gastric carcinoma.…”

“…Our search of the available literature revealed no reports of the use of CT to detect gastric carcinoma. From a practical standpoint, this subject may be contro- versial because an early gastric cancer may be confined to the mucosa, without causing thickening of the gastric wall [4], and the spatial resoluton of current CT scanners may not surpass doublecontrast upper GI series in demonstrating fine mucosal details [6]. However, CT's capabilities in this area must be borne in mind since gastric cancer can be detected during scanning for other reasons [1], including searches for metastatic disease [4].…”

Upper GI series and CT scans of 23 patients with advanced gastric cancer were reviewed and correlated to determine CT's capability in detecting gastric tumors. The CT images of the gastric carcinomas revealed either a mass or thickening of the wall. These abnormalities were present in 78% of the cases whereas CT demonstrated a "mass" in 52%. The most difficult site for CT diagnosis of gastric cancer was the antrum. Diagnostic accuracy of CT in evaluating tumor invasion of adjacent structures is reportedly high. However, in the present study this was not necessarily true. In 4 of 5 patients whose gastric tumors proved unresectable, CT failed to reveal adjacent invasion. This suggests that CT is not always reliable in predicting surgical resectability.

“…Most of them were due to obvious motion artifacts or the emaciation of patients. For extremely emaciated patient, there is a minimal fat interval between the stomach and nearby organs, which might result in inaccurate staging [8] . In two cases, the metastases to the peritoneal and omentum were undetected, possibly due to the limited MR resolution of low field strength and the relatively small size of the lesions.…”

AIM:To evaluate the application o� magnetic resonance imaging (MRI) to the preoperative staging o� advanced gastric cancer. METHODS:An MRI (SE sequence) was preoperatively per�ormed on 34 patients with advanced gastric cancer. The tumors were located at the cardia �undus in 11 patients, the corpus in 14, the antrum in ten and throughout the entire stomach in two. The images were analyzed and staged on the basis o� the criteria proposed by Matsushita M. The results were compared with the corresponding histopathologic findings to analyze the rate of diagnostic accordance. RESULTS:The diagnostic rate accuracy by MRI was 77.8% (seven out o� nince) �or T2 tumors; 77.3% (17 out o� 22) �or T3 tumors and 100% (three out o� three) �or T4 tumors, with the overall accuracy equaling 79.4%. When grades T3 and T4 tumors were considered as a single group to determine the presence or absence o� extraserosal invasion using MRI technology, the diagnostic accuracy was 88.3%. Statistically, MRI staging showed a signi�icant correlation with the corresponding histopathologic staging using the Spearman correlation test (r s′ = 0.743, P < 0.01). When the concordance between MRI and histopathologic staging results were studied according to tumor location, the staging accuracy was highest (90.9%) in tumors located in gastric cardia �undus.CONCLUSION: MR imaging is moderately valuable when staging advanced gastric cancer, especially �or tumors located in gastric cardia �undus.

“…Subsequently, the sections in the liver region were repeated after administering 100 ml of intravenous contrast material (65% Uroangiografin) by continuous infusion. To assess local findings it is fundamental to obtain good gastric repletion to enable one to measure the thickness of the gastric wall [22][23][24], Measurement of the gastric wall was performed, as advised by Lee et al [22], from the base of the folds to the interface provided by the outer limit of the wall and the perigastric fat. The thickness of the gastric wall measured using CT was 1.8 ± 0.51 cm.…”

The purpose of our study was to assess the value of CT in the preoperative staging of 40 patients with gastric cancer and correlate the CT findings with surgical and pathological findings. The average age was 63.3 years (35–76 years). There was a predominance of males (24 cases) over females (16 cases). The CT results are grouped according to the stages described in the literature. All tumors were adenocarcinomas; once the surgical and pathological findings were known, we used the p-TNM classification of the International Union Against Cancer. The results from our series were as follows: (1) CT assessment: 13 patients belonged to stage II, 18 to stage III, and 9 to stage IV. There were no stage I cases. (2) Stages according to TNM classification: in our series, there was no stage I case. There were 5 patients belonging to stage II, 8 to stage III-A, 14 to stage III-B and the remaining 13 to stage IV. (3) Correlation between stages based on CT findings and operative procedure used: there is a statistically significant correlation (p < 0.05) between the CT findings and operative procedure used. In conclusion, we believe that CT, if done correctly, is an accurate preoperative staging method in gastric carcinoma.
