When a doctor orders an mri for the head, they seek precise information about the brain and its surrounding structures

This information is often unobtainable through a physical examination or basic laboratory tests, making the mri a powerful diagnostic tool for investigating neurological symptoms.

This procedure adds distinct steps to the total time spent in the magnetic bore. Such mri contrast agents shorten the relaxation times of nuclei within body tissues following oral or intravenous administration Due to safety concerns, these products carry a black box warning in the us. Why scan times vary the overall duration of the brain mri can extend significantly beyond the standard time if specialized imaging is required

The use of a contrast agent, most commonly gadolinium, is a primary reason for longer exams, often adding 15 to 20 minutes If contrast is used, sequences are first run without the agent. Following the preparation instructions provided by the imaging facility is necessary to ensure the safety of the patient and the accuracy of the final scan
