Abstract :

<p>&nbsp;Objectives: Primary hepatic neuroendocrine tumors (PHNET) are extremely rare and difficult to distinguish from primary and metastatic liver cancers since PHNETs blood supply comes from the liver artery. This study aims to investigate CT and MR imaging findings of primary hepatic neuroendocrine tumor (PHNET) and correlation with the 2010 WHO pathological classification. Methods: We examined CT and MRI scans from 29 patients who were diagnosed with PHNET and correlated the data with the 2010 WHO classification of neuroendocrine tumors. Results: As tumor grades increase, the capsule begins to lose integrity and tumor apparent diffusion coefficient (ADC) values decrease(grade 1: 1.39&plusmn;0.20&times; 10&minus;3 mm2/s versus grade 2: 1.26&plusmn;0.23&times; 10&minus;3 mm2/s versus grade 3: 1.14&plusmn;0.17&times; 10&minus;3 mm2/s). Conclusions: CT and MRI can reflect tumor grade and pathological features of PHNETs, which are helpful in accurately diagnosing PHNETs.</p>
