ABSTRACT
Background: Eradication of Helicobacter pylori (Hp) effectively is becoming exceedingly challenging due to the increase in antibiotic resistance and recurrence of Hp infection. Aims: To explore the effect of an oxygen-enriched environment established by hydrogen peroxide (H
ABSTRACT
Objective To evaluate the clinical value of radionuclide pulmonary perfusion imaging in diagnosing acute pulmonary embolism.Methods Radioactive pulmonary perfusion imaging was performed in 25 patients clinically suspected for acute pulmonary embolism,meanwhile,imaging of deep veins of lower limb was taken.Results Multiple segments of abnormal blood perfusion were found in 23 of 25 patients,among them,radioactivity defects were found in 41 segments,radioactivity rarefied areas were found in 84 segments.Deep venous thrombosis was detected in 6 patients.Conclusion Radionuclide pulmonary perfusion imaging is a non-invasive and effective method in diagnosing acute pulmonary embolism.
