To investigate the impact of respiratory training on patients with pulmonary infection who accepted magnetic resonance imaging (MRI) examination.

Total of 85 patients with pulmonary infection who accepted MRI examination during January 2013 to January 2015 were collected in this study. Patients were randomly assigned to observation group and control group. The two groups were given basic nursing and respiratory assessment, and the observation group underwent breathing training before the MRIs. The image quality of MRI and the period of the examination patients in two groups were compared.

All the patients fininshed MRI examination. The image quality of the observation group was significantly better than that in the control group (U = 3.85, P = 0.000). The imaging qualities of of the observation group were significantly higher than the control group (97.67% vs 76.19%; χ² = 8.704, P = 0.003). The period of MRI examination for the observation group was significantly shorter than the control group (11.3±1.7 min vs. 14.2±2.2 min; t =-6.81, P = 0.002). The period of dynamic enhanced scan for the observation group was significantly shorter than the control group (4.1±1.0 min vs. 4.1±1.0 min; t =-3.92, P = 0.005).

Respiratory training could shorten the MRI examination duration, improve the image quality and increase the lesion detection rate and accuracy of diagnosis.
