Final answer:
An oblique view on a Myelogram shows the lateral aspects of the spinal canal, highlighting nerve roots and potential impingements or displacements.
Step-by-step explanation:
An oblique view on a Myelogram demonstrates the lateral aspects of the spinal canal, allowing for detailed visualization of the nerve roots exiting the spinal cord. Specifically, it can show impingement or displacement of these structures, which could be caused by conditions such as herniated discs, tumours, or stenosis. A myelogram involves injecting contrast dye into the spinal canal to enhance imaging and is often followed by CT scanning for more detailed pictures.
