What is the purpose of the T1 sagittal sequence in spine imaging?
To primarily show the vertebral column and neural arches
What is the signal intensity of the cortical bone and posterior elements in T1 sagittal images?
Decreased signal intensity

Relatively low signal intensity
Which sequence is best to show the pathology of the spinal cord?
T2-weighted imaging
What is the purpose of allowing sufficient overlap of vertebral bodies when imaging the entire spine?
To ensure all anatomy is imaged
Learn about the imaging protocol for evaluating suspected localized tumours or infections in the lumbar spine, including the types of scans required and the regions to be covered. Understand the importance of T1 and T2 weighted sagittal scans followed by axial scans through clinically indicated levels.
