Abstract
Objective To investigate the nursing highlight of different contrast medium to detect gastric lesions by spectral CT. Methods A total of 150 patients with gastric cancer were averagely divided into experimental group and control group according to coin toss. The 20 ml iohexol mixed with 1 500 ml warm water were used in the experimental group, but only oral warm water was used in the control group. The monitored result of gastric cancer, adverse reactions and appropriate care were evaluated. Results The corrective rate of spectral CT for gastric cancer detection in the experimental group and control group were 96.0% and 85.3% respectively, and the difference was significant (χ2=5.042, P 0.05). However, 73.3% patients in the experimental group underwent anxiety or depression, which was significantly higher than that in the control group (45.3%), with a statistically significant difference (χ2=12.185, P<0.01). Conclusions Iohexol can be used as a good developer spectrum of spectral CT, which may also improve the detection rate of gastric cancer. Meanwhile, corresponding nursing is also important during the process. Key words: Body section radiology, spiral computer; Gastric cancer; Nursing; Contrast medium
