A 67-year-old male with a hepatocellular carcinoma in the right lobe of the liver. a Transverse gradient recalled echo-in phase T1-weighted magnetic resonance image shows an isointense tumor. b Transverse gradient recalled echo-out phase T1-weighted magnetic resonance image shows an isointense lesion. c Transverse fast spin echo fat-saturated T2-weighted magnetic resonance image shows an isointense tumor with center high-signal-intensity strip. 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 no enhancement in the all phase. 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 = 5.89. n Localized magnetic resonance image shows location of the voxel of interest in tumor. o A choline-containing compound peak at 3.2 ppm was detected in tumor in 1H magnetic resonance spectrum, the choline-containing compound-At = 6.66
