Whether an angiogram or MRI is better depends on the specific medical situation and what information the doctor is looking to gather. An MRI uses magnetic fields and radio waves to produce detailed images of internal structures within the body, including the spinal cord and brain. It can be used to detect a wide range of medical conditions, including abnormalities in the spinal cord and blood vessels, as well as other soft tissue and bone abnormalities. In general, an angiogram is more invasive than an MRI and carries a slightly higher risk of complications such as bleeding,stroke or infection. However, an angiogram can provide more detailed information about blood vessels than an MRI and is often the preferred test in particular situations. Ultimately, the choice between an angiogram and an MRI depends on the specific medical situation and the doctor's recommendations.
