36. X-ray images of the main pathological processes in the bones

BONE TUMOUR

1. Detected by plain film, CT, and MRI finding.
2. Primary or metasisitic (2 forms: lytic and blastic)

When is CT better than MRI

1. When looking for relation between cortical bone and joint surface in acetabulum and tibial.
2. CORTEX are white in CT (ez to see).

MRI used for soft tissue and also bone marrow itself. Allows us to see the fluid presented.

How to examine cervical fracture:

Has 5 basic views: lateral, AP, left oblique, right oblique, and open mouth odontoid.

Process:

1. Count segment
2. Examine alignment
3. Examine precervical soft tissue.
4. Follow cortex with vertebral segment
5. Compare disk space
6. Identify odontoid processcheck alignment of lateral masses of C1, C2 and open mouth vied
7. Check midline position of spinous precess

Examine thoracic spine (used AP and lateral view)

1. AP view, count number of thoracic segment and corresponding ribs.
2. Check each pedicle
3. Soft tissue on each side oft he to thoracic spine.
4. Laterally, evaluate the height and disk space

Evaluate lumber spine

1. AP view: vertebral alignment, pedicles and transverse process
2. Oblique view: check for spondylosis and facet alignment
3. Lateral view: evaluate the vertebral body height and disk space.
4. 4. 2 most common area of disk disease: L4-L5 and L5-S1.
