The latter is popular with children, as they can listen to music to calm any anxiety during the procedure. Staff will ensure that they are as comfortable as possible by providing blankets or cushions.Įarplugs or headphones will be provided to block out the loud noises of the scanner. Once the patient has entered the scanning room, the doctor will help them onto the scanner table to lie down. The radiologist, a doctor who specializes in medical images, will then talk the individual through the MRI scanning process and answer any questions they may have about the procedure. Patients will sometimes receive an injection of intravenous (IV) contrast liquid to improve the visibility of a particular tissue that is relevant to the scan. Often they can be given medication prior to the MRI to help make the procedure more comfortable. Individuals who are anxious or nervous about enclosed spaces should tell their doctor. This can also include medical devices, such as cochlear implants, aneurysm clips, and pacemakers. The doctor will ask the patient to remove any metal jewellery or accessories that might interfere with the machine.Ī person will probably be unable to have an MRI if they have any metal inside their body, such as bullets, shrapnel, or other metallic foreign bodies. As magnets are used, it is critical that no metal objects are present in the scanner. On arrival at the hospital, doctors may ask the patient to change into a gown. There is very little preparation required, if any, before an MRI scan.

Conclusion: Gadoxetic acid is used to perform more complete examinations of cholangioresonance studies and to identify more precisely lesions in the bile duct without being essential and to be used it must be contrasted with liver function data. The analysis showed, as a diagnostic test for alterations of the bile duct, that gadoxetic acid has a sensitivity of 100%, a specificity of 81% and an efficiency of 90% (95% CI: 78.3-97.2% p <0.001). In diagnostic terms, gadoxetic acid enabled the characterization of cholecystectomy lesions in eight cases (27.5%), of bile duct alterations not related to cholecystectomy in another eight (27.5%) and of the normal bile duct in 13 cases (45%). In the remaining 33% it was not possible to visualize this route. Results: Gadoxetic acid allowed to characterize the bile duct in 67% of patients. Material and methods: A descriptive, observational, cross-sectional and retrospective study was performed in patients with bile duct involvement by magnetic cholangioresonance and using hepatospecific gadoxetic acid contrast medium to characterize bile duct abnormalities. Abstract: Objective: To assess the normal biliary anatomy and its alterations using the contrast gadoxetic acid to evaluate its diagnostic efficacy.
