| Purpose:Quantitative determination of the issue of liver density by CT,and ultrasound examination,CT and ultrasound of fatty liver in different diagnosis of the extent and characteristics of the performance. At the same time the clinical diagnosis for the future treatment of fatty liver and fatty liver in traditional Chinese medicine clinical observation provide a basis.Materials and Method:The author collected from June 1,2008 to March 15,2010 in the Provincial Hospital outpatient and inpatient diagnosis of liver disease fatty liver in 90 patients suspected of clinical data,all patients underwent liver CT and B-ultrasound. Liver CT scan which measured values of the liver and spleen CT value of CT with liver/spleen CT ratio with the relative density of intrahepatic vascular diagnostic classification criteria. The CT and the results of B-ultrasound diagnosis and quantitative analysis,respectively. The group of 90 patients,62 males and 28 females,aged from 20 to 65 years,mean age 41 years,duration of 1 to 18 years,an average of 6.5 years.73 cases of patients with long-term drinking history,body fat in 57 cases,of which 13 cases were associated with diabetes mellitus,hyperlipidemia associated with 15 cases. Main clinical manifestations were abdominal distension, abdominal pain, loss of appetite, fatigue, nausea, vomiting, liver or right upper quadrant pain,13 patients without obvious symptoms.All patients in the examination greasy foods the day before fasting, fasting next morning to check. All patients were treated with hospital SIEMENS spiral CT scanners, routine liver and spleen CT scan examination, in some cases additional TLC, cross-sectional scanning, oral contrast agent(containing 2% aqueous solution of diatrizoate) 500ml,30min before the examination Oral 2/3 the amount of bed rest before the test amount served. Scan parameters:120kV, 250mA, window width 200HU, window level 45HU, conventional layer away from the 10mm, thickness 10mm, continuous scanning. Scan range: top diaphragm to the lower edge of the liver, the liver four different homogeneous areas selected to measure, try to avoid video artifacts and intrahepatic blood vessels, the mean value as a result, and compared with the spleen CT scan obtained the value of liver/spleen ratio.512 by the Court of Siemens ultrasound color Doppler ultrasonic diagnostic apparatus, the probe frequency of 3.5Hz. Supine position, repeated use of conventional methods is the lateral scanning of liver,liver observed shape,size,capsule boundary, liver echo spot size, intensity, extent and scope of distribution and attenuation observed intrahepatic biliary system, in particular, hepatic and portal vein distribution and wall reflection and so on.Results:90 patients with fatty liver were confirmed by CT and B-ultrasound, CT diagnosis of which 23 patients with mild fatty liver, liver CT value of the average of about 46HU (35～54HU); moderate fatty liver in 44 cases, the average liver CT value of about 30HU (24～37HU); 17 cases of severe fatty liver, liver CT value of the average of about 14HU (-15～23HU),, normal in 6 cases, the rate was 93.3%. And 90 patients with fatty liver using B ultrasound diagnosis of fatty liver in 21 patients with mild, moderate,39 cases of fatty liver, severe fatty liver in 16 cases, normal in 14 cases, B ultrasound diagnosis of fatty liver consistent rate of about 84.4%, the difference not statistically significant (P>0.05); in the CT diagnosis of 23 patients with mild fatty liver in 11 cases ultrasound diagnosis of mild (47.8%), abnormal in 8 cases (34.8%), normal in 4 cases (17.4%); between the two in the diagnosis of mild fatty liver was significantly (P<0.01).Conclusion:CT diagnosis of fatty liver was significantly better than the accuracy and sensitivity of ultrasonography, especially for the diagnosis of mild fatty liver, the current studies have shown that fatty liver may be the early stage of liver fibrosis and cirrhosis of the liver to change, so early detection, diagnosis And treatment of fatty liver is particularly important. |
