Abstract：Objective To explore the characteristics of imaging findings of spiral CT and MRI examination in diagno-sing hepatic focal nodular hyperplasia ( FNH) , and improve the diagnostic accuracy rate of FNH. Methods 36 FNH cases confirmed by pathology during May 2011 and February 2013 were selected and were divided into spiral CT group ( n=14 ) , MRI diagnosis group (n=12) and spiral CT plus MRI group (n=10), on the basis of different image logical examinations. Then their image logical features and diagnostic accuracy rate were evaluated separately. Results A total of 15 lesions in 14 cases in spiral CT scan group were scanned and showed that 10 FNH lesions were low density;enhanced scan showed that ar-terial lesions were obviously enhanced;four lesions venous phase and delayed phase were reduced to equal density;the sensi-tivity of FNH diagnosis was 78. 6%(11/14), and the specificity was 85. 7%(12/14). A total of 13 lesions in 12 patients with MRI scan group were scanned and showed that;there were eight lesions of T1WI sequence showing low signal and eight lesions of T2WI sequence showing mixed high signal;enhanced scan showed that arterial lesions were high signal;the venous phase and delayed phase showed a decreasing trend; the sensitivity of diagnosis FNH was 83. 3% (10/12), the specificity was 100. 0%. In spiral CT plus MRI group, both the sensitivity and specificity of diagnosis FNH were 100. 0%. Conclusion The joint use of spiral CT and MRI examinations can remarkably improve diagnostic accuracy rate, but because the sample is few, we still need more samples to confirm this prospective study.
