Liver-specific agents for contrast-enhanced MRI: role in oncological imaging
Liver-specific magnetic resonance (MR) contrast agents are increasingly used in evaluation of the liver. They are effective in detection and morphological characterization of lesions, and can be useful for evaluation of biliary tree anatomy and liver function. The typical appearances and imaging pitfalls of various tumours at MR imaging performed with these agents can be understood by the inter...
متن کاملUse of contrast agents in oncological imaging: magnetic resonance imaging
Magnetic resonance plays a leading role in the management of oncology patients, providing superior contrast resolution and greater sensitivity compared with other techniques, which enables more accurate tumor identification, characterization and staging. Contrast agents are widely used in clinical magnetic resonance imaging; approximately 40-50% of clinical scans are contrast enhanced. Most con...
متن کاملLiver-specific contrast agents
In the patient with cancer, magnetic resonance imaging is increasingly used as a diagnostic tool for disease detection, lesion characterization, as well as the assessment of treatment response. Although non-contrast T1-weighted and T2-weighted imaging, together with low molecular weight extracellular gadolinium contrast-enhanced T1-weighted magnetic resonance imaging remain the cornerstone for ...
متن کاملAutomatic Liver Segmentation in Contrast-enhanced MRI
A fully automated method for liver segmentation in contrast enhanced abdominal MRI scans is presented. Liver shape and volume are obtained utilizing a context based approach. Compared to manual segmentation, the obtained liver volumes differ less than 10%. The mean sensitivity of 0.92 is comparable to other published liver segmentation methods.
متن کاملHepatobiliary-specific MR contrast agents: role in imaging the liver and biliary tree.
Hepatobiliary-specific contrast agents are one of several classes of contrast agents available for magnetic resonance (MR) imaging of the liver. These agents are taken up by functioning hepatocytes and excreted in the bile, and their paramagnetic properties cause shortening of the longitudinal relaxation time (T1) of the liver and biliary tree. The three contrast agents that have been developed...
