MRI scans of the spine are vital as spinal tumors are becoming more common, aiding in early detection. Let’s examine how MRI contributes to diagnosing and managing spinal tumors today.
Overview of Spinal Cord Tumors
Spinal cord tumors are growths located within or near the spinal cord, classified as either intrinsic or extrinsic. Understanding these categories is essential for accurate diagnosis and effective treatment.
Categories of Spinal Cord Tumors
Intrinsic tumors develop within the spinal cord, such as astrocytomas, ependymomas, and other glial cell tumors. Their deep location makes them challenging to treat.
Extrinsic tumors are located outside the spinal cord but may compress it. Examples include meningiomas, schwannomas, and metastatic tumors.
Determining whether a tumor is intrinsic or extrinsic guides treatment decisions. Intrinsic tumors require specialized surgery, while extrinsic tumors are more accessible but still demand careful management to safeguard the spinal cord. Understanding How MRI Detects Spinal Cord Tumors
