The diagnostic value of contrast-enhanced fluid-attenuated inversion recovery fat saturation magnetic resonance imaging in leptomeningeal metastasis of lung cancer
To investigate the diagnostic value of T2-weighted imaging fluid-attenuated inversion recovery fat saturation (T2WI-FLAIR-FS) enhanced scanning in lung cancer with leptomeningeal metastasis.
Methods:
Routine T1 weighted imaging fat saturation (T1WI-FS) enhancement and T2WI-FLAIR-FS scanning were performed in 20 patients with confirmed soft meningeal metastasis of lung cancer by cerebrospinal fluid (CSF) cytology
and the scannin
g results were retrospectively analyzed.
Results:
3 cases were missed in conventional T1WI-FS enhanced scan
all cases showed soft meningeal thickening and enhancement in T2WI-FLAIR-FS enhanced scan
which was consistent with the results of CSF examination
and the lesion range shown in T2WI-FLAIR-FS enhanced scan was larger than T1WI-FS enhanced scan (
P
<0.05).
Conclusion:
T2WI-FLAIR-FS enhanced scan showed that lung cancer with leptomeningeal metastasis was superior to conventional T1WI-FS enhanced scan
and could improve the diagnostic level of lung cancer with leptomeningeal metastasis.
