Liver Fat Measurement By MRI 

Liver is the largest body gland weighing about 1500 grams, which is composed of two right and left lobes. Most metabolic activities (more than 500 different activities) such as storage of minerals and vitamins and conversion of ammonia to urea take place in the liver and the most important function of the liver is to play the role of a filter for the blood. One third of the liver blood is supplied through the hepatic artery (the aorta originates) and two-thirds is supplied through the portal vein (digestive tube). In addition, it contains some ducts for removing bile (bile salts are necessary for digestion and absorption of its solube fats and vitamins) through which hepatocytes (bile) will exit. Life goes on through 20 percent of the liver activity. 

Natural fatty liver or steatosis is a general term to refer to the accumulation of fat in the liver. Fat in the liver is normal, but if this amount of fat exceeds 5 to 10 precent of the total weight of the liver, the person is suffering from fatty liver. Fatty liver is a curable disease, but in the following cases, it can have dangerous complications. 

Various types of fatty liver
Alcoholic fatty liver 
Non-alcoholic fatty liver 
Acute fatty liver of pregnancy (AFLP) 

Symptoms of fatty liver: 
Weight loss or appetite 
Or pain in the liver area

Causes of fatty liver disease: 
Diabetes type II 
High blood pressure 
Taking Aspirin and tetracycline 
High blood cholesterol 
Polycystic ovary syndrome Hypothyroidism 
Gastric bypass surgery 

Diagnostic methods: 
Blood tests (checking liver enzymes)
CT scan 
Ultrasound and FibroScan 
MRI is the newest and most accurate non-invasive method for diagnosing fatty liver. 

Fatty liver ultrasonography 
Ultrasounography is the first imaging technique used in the screening of the patients with chronic liver disease. Fatty liver ultrasound has more increased echo compared to the ultrasound of kidneys and spleen. 

Recently, FibroScan that specifies the amount of liver fibrosis according to ultrasound offers a calibration for the amount of liver fat. 

CT scan of fatty liver 
CT scan is a remarkable diagnostic method for evaluating fatty liver. 

MRI of fatty liver 
Currently, MRI imaging is considered the most accurate and remarkable imaging method for evaluating fatty liver condition and measuring the amount of liver fat. According to the existing standards for calibration of the amount of fat storage, MRI is a non-invasive imaging method, which is highly accurate and  enjoys a particular advantage to the other imaging methods for assessing liver fat storage. 

This imaging method was used this year for the first time in Tehran by Pardis Noor Medical Imaging Center. In this method, the percentage of liver cells with fat is determined quantitatively using several imaging modes and the necessary calculations. 
The determination of the quantitative amount of liver fat can have an effective role in evaluating the effectiveness of treatments.
