Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15] MRI can be made sensitive to the motion of molecules.
In some, the x-ray findings may correspond to symptoms of back stiffness with flexion/extension or with mild back pain. [2] Back pain or stiffness may be worse in the morning. [ 4 ] Rarely, large anterior cervical spine osteophytes may affect the esophagus or the larynx and cause pain , difficulty swallowing [ 5 ] [ 6 ] or even dyspnea . [ 7 ]
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]
Axial and coronal images in the portal venous phase. Increased pressure in the sublobular branches of the hepatic veins causes an engorgement of venous blood, and is most frequently due to chronic cardiac lesions , especially those affecting the right heart (e.g., right-sided heart failure ), the blood being dammed back in the inferior vena ...
Abdominal ultrasonography of the liver, as a sagittal plane through the midclavicular line, with some standard measurements [2] Right lobe of the liver at the midclavicular line at ages 0 to 7 [16] Suspicion of hepatomegaly indicates a thorough medical history and physical examination , wherein the latter typically includes an increased liver ...
Metabolic dysfunction–associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD), [a] is a type of chronic liver disease. This condition is diagnosed when there is excessive fat build-up in the liver ( hepatic steatosis ), and at least one metabolic risk factor.
Magnetic resonance myelography (MR myelography or MRI myelography) is a noninvasive medical imaging technique that can provide anatomic information about the subarachnoid space. It is a type of MRI examination that uses a contrast medium and magnetic resonance imaging scanner to detect pathology of the spinal cord , including the location of a ...
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.
