Abstract
Introduction: Gastric tumor is relatively common disease entity in day to day radiologic
pratice.Gastric cancer acounts for the majority of gastric neoplasm followed by GIST and
gastric lymphoma. Imaging plays a vital role in diagnosis and staging of gastric neoplasm
particularly gastric cancer.Computed tomography remains the most common and widespread
tool for the staging of the diseases
The role of computed tomography in the study of gastric carcinoma is mainly for preoperative
local and distant staging; post-therapeutic control and follow-up
Method: The study was conducted at TASH ,Addis Ababa ,Ethiopia from September 2019 to
August 2020.Hospital based retrospective cross sectional study was conducted to address the
specific objective during study period. The Study was conducted among patients being evaluated
at Tikur Anbessa Specialized Hospital oncology department who have both MDCT result
reported by senior radiologist and pathology result . Data was collected by evaluating the
MDCT report and biopsy result from pathology and oncology department by using structured
questionnaires. The data was checked for clarity and completeness. Computerized data analysis
was conducted by using SPSS version 20 software.
Result: Total of 80 gastric tumor patients were evaluated .66(82.5%) were gastric cancer
,12(15.5%) were gastric GIST and 2(2.5%) were primary gastric lymphoma. The age range of
gastric cancer were 25 to 85 years with mean age of 52.6 year.The mean age of GIST was 54
year and the age range of the 2 lymphoma were 35 to 54 years.56.7 % of gastric cancer were
men and 66 % of GIST were men. This study showed that 56 % of gastric cancer were
intestinal histologic type, 33. 4 % were diffuse histologic type and 10.6% were indeterminate
histologic adenocarcinoma .Acuracy of MDCT for staging T4 tumor is 90.9% and 44.5 % for
T3 .
Conclusion: MDCT has relatively high diagnostic sensitivity and specificity for detection and
diagnosis of gastric tumor .It has high acuracy to differentiate gastric GIST from other gastric
tumor . MDCT has high acuracy for correctely staging T4 tumor but it had relatively low
acuracy of staging T2, T3 tumor and nodal staging
