T1-mapping technology for differential diagnosis of hepatic cyst,hemangioma and HCC provides a new quantitative method, especially for no-enhanced
T1-mapping, have promise of clinical application.

cyst. appeared hyperintensity on
T2WI-fs and hypointensity on
contrast image, ADC value 2.81×10-3mm2/s, pre-contrast T1=3125ms, post-contrast
T1=2800ms, decrease rate of T1 = 10.4%.
(g~l) Hemangioma.
appeared hyperintensity on
both T2WI-fs and contrast image. ADC value 1.53×10-3mm2/s,
pre-contrast T1=1828ms, post-contrast T1=210ms, decrease
rate of T1 = 88.5%.
(m~r) HCC.
appeared hypointensity on
both T2WI-fs and delayed contrast
image.
ADC value 0.95×10-3mm2/s,
pre-contrast T1=1208ms, post-contrast T1=530ms, decrease
rate of T1 = 56.1%
