Role of MRI and CT Scanning in the Diagnosis of PDB

Risk‐benefit balance

The radiation exposure with CT scans is higher than plain X‐rays or radionuclide bone scans, but MRI scans do not involve radiation exposure.

Quality of evidence

Very low

Patient values and preferences

Patients with claustrophobia may prefer to avoid MRI.

Costs and use of resources

Both CT scans and MRI scans are considerably more expensive than plain X‐rays or radionuclide bone scans.

Recommendation

There was insufficient evidence to recommend MRI or CT imaging for the diagnosis of PDB and neither technique is recommended for this purpose. These imaging techniques are recommended for the assessment of disease complications.
