Enhanced MRI can detect bile duct obstruction. If a patient has a bile duct obstruction, it can be detected by a flat MRI scan of the liver and gallbladder, such as a bile duct MRI. On the other hand, strengthening MRI is to increase the signal intensity of the tissue by injecting a contrast agent on top of the plain scan, which can obtain better image display, improve the detection rate of the disease, and make the diagnosis of the disease more accurate. Therefore, enhanced MRI can detect bile duct obstruction. If bile duct obstruction is highly suspected on MRI scan, it is recommended to consider the need for strengthening MRI in conjunction with your doctor’s examination and initial judgment. It is important to note that a contrast medium is injected into the MRI, which can cause allergic reactions. After the examination, try to drink as much water as possible to speed up the body’s metabolism and promote the rapid elimination of the contrast agent through increased urine.
