Imaging of bone disease

Imaging of bone disease
1- plain x-ray

2-radio isotope

3- CT scan

4- MRI
1-BONE DENSITY

2-PERIOSTEAL REACTION

3-CORTICAL THICKENING

4- ALTERATION IN TRABECULAR PATTERAN

5-ALTERATION IN THE SHAPE OF BONE
Generalized :
a-osteoporosis
b-osteomalacia and rickes
c-hyperparathyroidism,renal osteodystrophy
d- mutiple myeloma
e-osteogensis imperfecta

Localized :
Fracture of one bone
Sudeck atrophy -sever osteoporosis
Increase bone density
a-osteopetrosis
b-myelosclerosis
c-sclerotic metastasis
d-paget s disease
e-prostatic metastasis

Excess bone prodused by the periosteum which occurs in response to such condition
a-neoplasm
b-inflammation
c-trauma
Alteration in the shape of the bone
a-achondoplasia
b-multiple stenosis
c-acromegaly
e-expnding bone tumor
Due to defenciency of the protein matrix
Matrix reduced in quantity
Caueses:
1-idiopathic
2-cushing syndrome
3-postmenopausal
Lack of calciumin the body tissue
With poor mineralization of osteoid
If this occurs before epiphyseal closure
It is called rickets while in adults it is called osteomalacia

Benign
None
Solid
More aggressive or malignant
Lamellated or onion-skinning
Sunburst
Codman’s triangle
