Magnetic resonance elastography (MRE) is a form of elastography that specifically leverages MRI to quantify and subsequently map the mechanical properties (elasticity or stiffness) of soft tissue. First developed and described at Mayo Clinic by Muthupillai et al. in 1995, MRE has emerged as a powerful, non-invasive diagnostic tool, namely as an ...
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing ...
Hepatogram. A hepatogram is a medical imaging examation of the liver. It is done via magnetic resonance imaging and consists of liver fibrosis and inflammation assessment, as well as steatosis grading. The current imaging protocol for a hepatogram is magnetic resonance elastography for fibrosis and inflammation assessment, and proton density ...
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]
Images taken by CT scan, X-ray, or MRI show enlarged intrahepatic (in the liver) bile ducts due to ectasia. Using an ultrasound, tubular dilation of the bile ducts can be seen. On a CT scan, Caroli disease can be observed by noting the many fluid-filled, tubular structures extending to the liver. [4]
Many imaging modalities are used to aid in the diagnosis of malignant liver tumors. These include sonography (ultrasound), computed tomography (CT) and magnetic resonance imaging (MRI). Tumor markers , chemicals sometimes found in the blood of people with cancer, can be helpful in diagnosing and monitoring the course of liver cancers.
D038524. Diffusion-weighted magnetic resonance imaging (DWI or DW-MRI) is the use of specific MRI sequences as well as software that generates images from the resulting data that uses the diffusion of water molecules to generate contrast in MR images. [1][2][3] It allows the mapping of the diffusion process of molecules, mainly water, in ...
A liver segment is one of eight segments of the liver as described in the widely used Couinaud classification (named after Claude Couinaud) in the anatomy of the liver.This system divides the lobes of the liver into eight segments based on a transverse plane through the bifurcation of the main portal vein, [1] arranged in a clockwise manner starting from the caudate lobe.
