Abstract:
Objective To evaluate the clinical value of iohexol contrast agent in patients with malignant tumor by spiral CT scan combined with endoscopy.Methods 100 patients with pathologically confirmed malignancies were selected and randomly divided into two groups, with 50 cases in each group, the experimental group received iodohexanol contrast agent combined with spiral CT scan and endoscopy , the osmotic pressure of iohexol at 37℃600 mOsm/kg, 5 minutes before the injection of intravenous injection of 10 mg prophylaxis of dexamethasone, and then spiral CT scan was performed.The control group were treated with diatrizoate contrast agent combined with spiral CT scan and endoscopy.The osmotic pressure of diatrizoate was 1500 mOsm/kg at 37℃, and 10 mg of prophylactic drug dexamethasone was injected intravenously 5 minutes before the injection.And then a spiral CT scan was performed.Results The adverse reaction in experimental group was 4%, which was mild compared with 12% in control group ( P<0.05 ) .The tolerance and spiral CT image quality of experimental group were better than those of control group ( P<0.05 ) .Conclusion Iohexol contrast agent, whether adverse reaction or image quality than the effect of diatrizoate contrast agent , in the spiral CT scan combined with endoscopy in patients with malignant tumors of higher clinical value, can be more accurate diagnosis of malignant tumors.
