Sagittal MRI of the Lumbar Spine         (Return to List of Available Self-Test Images - Normal Structure)
This is a contiguous series of sagittal MRI images of the lumbar spine in a 19y old woman. On the left are T1-weighted images; on the right are T2-weighted images. The first set of images are to the left of the median sagittal plane, and the series progresses to the patient's right side. The T2-weighted images are not precisely through the same section as the T1-weighted images, but they are pretty close. You can look at the video frame by frame and try to identify the lettered structures to which lines are drawn. The answers will be revealed when you click on the appropriately labelled drop-down arrows below the image.
