Abstract
Objectives
To evaluate clinical usefulness of computed tomography perfusion imaging (CTPI) in
gastric cancer.
Materials and methods
Twenty subjects without gastric diseases (control group) and fifty patients with gastric
cancer were studied prospectively using CTPI examinations. Four perfusion parameter
values, i.e., blood flow (BF), blood volume (BV), mean transit time, and permeability
surface (PS), were calculated. The gastric cancer group was divided into three groups:
well differentiated, moderately differentiated, and poorly differentiated gastric
adenocarcinoma.
Results
Comparing the three groups, differences between the well-differentiated group and
the moderately differentiated group or the poorly differentiated group were all statistically
significant for BF, BV, and PS.
Conclusion
The BF, BV, and PS values could serve as indicators of the degree of malignancy of
gastric cancer.
