Brief Summary
Focal nodular hyperplasia (FNH) in liver is the second common benign hepatic tumor. It usually shows hypervascular mass on imaging studies and it is not easy to differentiate with other hypervascular malignant tumor. For diagnosis of FNH, contrast-enhanced ultrasonography (US) has been used to detect 'spoke-wheel sign', which can be typically seen in FNH. However, temporal window of vascular phase using contrast-enhanced US (CEUS) is very short (about 10 sec) and coordination of patient's respiration during US exam is absolutely needed. Thus, the investigators will use Superb-Microvascular imaging (SMI, Toshiba, Japan) for detection of 'spoke-wheel sign' in patients with proven FNH, which enable to detect slow micro vascular flow without using CEUS. First, to compare the detection rate of 'spoke-wheel sign' between CEUS using sonazoid (Perfluorobutane, GE healthcare) and SMI. Second, to compare the accuracy of size measurement between gray-scale US and SMI (reference standard: CEUS using sonazoid.)

Outcome Measures
Primary Outcomes (1)
Grading of spoke-wheel sign on CEUS using sonazoid and SMI in patients with focal nodular hyperplasia
a.To evaluate the detection rate of 'spoke-wheel sign' on CEUS using sonazoid and SMI (primary outcome). Each US findings during exam for patients with FNH were recorded by radiologist. The results were interpreted by consensus using 4 scale bar. 0\. Absence of 'spoke-wheel sign' 1. Mild suspicious of 'spoke-wheel sign' 2. Highly suspicious of 'spoke-wheel sign' 3. Definite "spoke-wheel sign'

Secondary Outcomes (1)
Measurement error of focal nodular hyperplasia between b-mode US and SMI according to the reference standard, CEUS
1 day
Study Arms (1)
SMI and sonazoid (single arm)
EXPERIMENTALPatients with focal nodular hyperplasia will undergo ultrasonography with Superb-Microvascular imaging and additional sonazoid-enhanced ultrasonography. SMI is a software function in a Toshiba Aplio 500 system. Sonazoid is contrast-material for US and it is a intervention for patient with FNH. Sonazoid will be administered at a dose of 0.015 mL/kg by manual bolus injection, followed by a 10 mL normal saline flush via a peripheral venous line
Interventions
Sonazoid: Commercially available contrast material for ultrasonography
Superb-Microvascular imaging: new sonographic software technique on ultrasonography to detect low-vascular flow without use of contrast media for ultrasonography
