[Abstract] Objective: To evaluate the image quality and clinical application of the routine magnetic resonance (MR) pulse sequences in lung cancer.Materials and Methods: Forty-three cases of lung cancer had done MR examinations at 3.0 T MR. Scan sequences were as followed, T2WI/TSE-BLADE, T2WI/HASTE, T1WI/VIBE-DIXON, DWI/EPI. Analysed the motion artifact, bronchia, difference of lung lesions and secondary atelectasis of the different scanning sequence images.Results: The motion artifacts from respiration and pulsation on the HASTE images were better controlled than other three sequences, The motion artifacts appeared at a rate of 2% (1/43). Bronchia showed best in the TSE-BLADE sequence; TSE-BLADE-T2, HASTE-T2 and EPI-DWI could distinguish neoplastci foci and secondary atelectasis, identification rate was 72.7%, 81.8%, 81.8%, respectively, but there was no statistically significant difference between each other (table probability was 0.3446, 0.3446, 0.3446, P=1.0000). VIBE-T1 sequence failed to distinguish them.Conclusion: 3.0 T MR conventional pulse sequence image respectively have advantages and disadvantages, which can complement each other, can play its unique advantages in the chest imaging.
