| Popis: | Gandolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) is a hepatobiliary contrast agent for MRI. It was reported that Gd-EOB-DTPA is useful to detect liver tumors and differentially diagnose benign and malignant pathologies in the liver. Since Gd-EOB-DTPA partially accumulates in the hepatocytes and bile via various transporters after intravenous injection, signal intensity in the liver increases on T1-weighted images. The signal intensity of the liver after Gd-EOB-DTPA injection depends on the Gd-EOB-DTPA uptake by hepatocytes and bile excretion. It is known tha the Gd- EOB-DTPA accumulating in the kidney is excreted to the urine through glomerular filltration. Because Gd- DTPA is concentrated in the renal tubules after being filtered at the Bowman’s capsule, and since it is neither secreted nor reabsorbed the concentrating and diluting function of the renal tubules can be studied by imaging techniwues. since renal function can be evaluated with Gd-EOB-DTPA can also be used to evaluate renal function. Eith the development of MRI equipment and rapid imaging techniques, temporal resolution had improved greatly. However, no previous study has been carried out on renal function using Gd- EOB-DTPA dynamic MR study that was correlated with estimated glomerular filtration rate (eGFR) and stage of chronic kidney disease (CKD) in the Japan Association of chronic kidney disease initiative. |
