The Liver Imaging Reporting and Data System (aka LI-RADS) is a quality assurance tool created and trademarked by the American College of Radiology in 2011 to standardize the reporting and data collection of CT and MR imaging patients at risk for hepatocellular carcinoma (HCC), or primary cancer of the liver cells. [1]
Abnormally increased liver stiffness is a direct consequence of liver fibrosis. The diagnostic performance of MRE in assessing liver fibrosis has been established in multiple studies. [17] [18] [16] [19] Liver MRE examinations are performed in MRI systems that have been equipped for the technique.
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
MRI contrast agents may be administered by injection into the blood stream or orally, depending on the subject of interest. Oral administration is well suited to gastrointestinal tract scans, while intravascular administration proves more useful for most other scans. MRI contrast agents can be classified [2] by their: Chemical composition
Liver biopsy is the biopsy ... Multiphasic MRI is useful in diagnosing various types of liver lesions such as hepatocellular carcinoma, cholangiocarcinoma ...
With the recent advances of noninvasive imaging, living liver donors usually have to undergo imaging examinations for liver anatomy to decide if the anatomy is feasible for donation. The evaluation is usually performed by multidetector row computed tomography (MDCT) and magnetic resonance imaging (MRI). MDCT is good in vascular anatomy and ...
MRI of a healthy liver (top row) and one with severe steatosis (bottom row) A liver ultrasound scan or magnetic resonance imaging (MRI) can diagnose steatosis, [73] but not fibrosis, and confirmation of early cirrhosis detection by ultrasound by other diagnostic methods is recommended. [70]
Liver image reporting and data system (LI-RADS) is a classification system for the reporting of liver lesions detected on CT and MRI. Radiologists use this standardized system to report on suspicious lesions and to provide an estimated likelihood of malignancy.
