Abstract
Objection
The purpose of this study is preliminarily to discuss stomach perfusion imaging technique with Multi-slice CT and its clinical application value in stomach neoplasm.
Methods
Fifteen patients with known stomach neoplasm performed perfusion imaging with 4 or 16 slice CT. Performing perfusion imaging in central slice of neoplasm, using CT cine scan, slice thick 10 mm/2i; with high pressure syringe, injecting quickly from right elbow-front vein, dosage 45–50 mL, injection rate 3.5–4.0 mL/s, scanning delay time 5 s, scanning total time 45 s. We performed perfusion CT post-processing using pancreatic mode of perfusion CT software. Blood flow (BF), blood volume (BV), mean transit time (MTT), and permeability surface (PS) of gastric wall and tumor were computed for every case.
Results
BF, BV, MTT and PS of gastric tumor were 116.68 ± 90.09 mL/(min ·100 g), 9.57 ± 8.12 mL/100 g, 10.07 ± 7.74 s, 20.78 ± 19.68 mL/(min ·100 g), respectively. The P values for each CT perfusion parameters between gastric tumor and normal gastric wall were 0.001, 0.021, 0.155 and 0.031, respectively.
Conclusion
Perfusion CT can provide hemodynamics of gastric tumors and play a key role in the diagnosis of gastric tumors. It’s clinical application prospect will be fully broad.
