T1-weighted T1W sequences provide good anatomical detail and enable delineation of the medulla, cortex, periosteum and soft tissues. However, it can be useful for detecting soft tissue or subperiosteal collections, especially in children, although an MRI will still be required for a more thorough assessment. To differentiate between infection and physiological marrow uptake, the white cell scan is combined with a bone marrow scan that uses Tc 99m -labelled colloid. Figure 2. The axial images are frequently diagnostic, demonstrating a linear cortical defect on multiple sequential images and, often, endosteal and periosteal callus formation. Alcian blue staining demonstrated an abundanCE OF acid mucin in the stroma. A normal nutrient foramen is seen on the coronal image blue arrow without adjacent edema.

The imaging of osteomyelitis
Bone marrow oedema is the earliest feature of acute osteomyelitis seen on.
There was no nuclear atypia and mitotic figures were not detected. This is a common longitudinal fracture orientation, although more difficult to recognize than the radially oriented version.
Magnetic resonance imaging MRI findings in acute osteomyelitis Bone marrow oedema is the earliest feature of acute osteomyelitis seen on MRI and can be detected as early as 1 to 2 days after the onset of infection 2.
Finally pain is experienced at rest.

MRI has surpassed bone scintigraphy as the imaging tool for stress anatomical detail and more precisely depicting the tissues involved. mild - moderate periosteal edema on STIR, no marrow changes.
These tests provide clear pictures of dense structures like bone, and are helpful in diagnosing chondromas.

|Abscesses demonstrate peripheral rim enhancement whereas tumours usually enhance heterogeneously 23. Making the Best Use of Clinical Radiology version 7. Two patients are presented with differing histories, but one diagnosis.
As with abscesses, sinus tracts are lined by hypervascular granulation tissue and will also demonstrate peripheral enhancement after intravenous contrast MRI has very high sensitivity for the detection of osteomyelitis; a normal MRI virtually excludes osteomyelitis 5.
This creates an ideal environment for bacteria to accumulate and proliferate 2.
