Fig. 4From: Phantom simulation of liver metastasis on a positron emission tomography with computed tomography scan after neoadjuvant chemoradiotherapy for distal esophageal cancer: a case reporta Sonography of the liver shows hypoechoic appearance over caudate lobe. b Contrast-enhanced computed tomography shows focally less enhancement in S1 of the liver. c Magnetic resonance imaging (MRI) of the liver shows a low signal intensity over the caudate lobe in T1-weighted images. d MRI of the liver shows a high signal intensity over the caudate lobe in T2-weighted imagesBack to article page
