Body part scans
| Scans within sample of GP-MSK-MRIs (342 body part scans for 306 referred patients) | Scans within all GP-MSK-MRIs (6,621 MRI referrals) | |
| Cervical spine | 11% (n=38) | 16.1% (n=1,071) |
| Thoracic spine | 4% (n=12) | 5.7% (n=377) |
| Lumbar spine (inc. sacrum and sacroiliac joint) | 28% (n=97) | 40% (n=2,664) |
| Shoulder | 4% (n=15) | 7.3% (n=484) |
| Elbow | <1% (n=1) | <1% (n=48) |
| Wrist/hand/fingers | <1% (n=1) | 1.9% (n=127) |
| Hip | 6% (n=20) (4 × cases requested bilateral imaging) | 6% (n=397) |
| Knee | 40% (n=139) (4 × cases requested bilateral imaging) | 35% (n=2,345) |
| Ankle/foot | 4% (n=14) (2 × cases requests for bilateral imaging) | 8.78% (n=581) |
| Other (sternum, sternoclavicular, brachial plexus, thoracic inlet, axillae, clavicle, scapula, upper arm, forearm, coccyx, groin, thigh, lower leg) | 1% (n=5) | 1.3% (n=84) |
χ2 analysis of body parts in the sample against the distribution in all scans, revealed x2=9.54, df=9 with p=0.388, that is, no significant difference, suggesting a sample representative of all MRIs.
