A 50-year-old female with a hemangioma in the left lobe of the liver. a Transverse gradient recalled echo-in phase T1-weighted magnetic resonance image shows a hypointense lesion. b Transverse gradient recalled echo-out phase T1-weighted magnetic resonance image shows a hyperintense lesion. c Transverse fast spin echo fat-saturated T2-weighted magnetic resonance image shows a hyperintense lesion. d Transverse spin-echo echo-planner image at b value of 600 s/mm2 shows high-signal-intensity lesion. e-h Multiple phase dynamic enhancement scan with liver acquisition with volume acceleration-extended volume magnetic resonance images show rapidly enhancing vessels at the periphery in the arterial phase. The lesion was then “filled- in” centripetally. k Localized magnetic resonance image shows location of the voxel of interest in tumor free tissue. m A choline-containing compound peak at 3.2 ppm was detected in tumor free tissue in 1H magnetic resonance spectrum, the choline-containing compound-Atf = 0.63. n Localized magnetic resonance image shows location of the voxel of interest in tumor. o No choline-containing compound peak was detected in tumor free tissue in 1H magnetic resonance spectrum, the choline-containing compound-At = 0
