| Early post-operative MRI | Neuroradiologist | Neurosurgeon | Neuro-oncologist | Total |
|---|---|---|---|---|
| Purpose | ||||
| Establish amount of residual tumour | 27 | 29 | 27 | 83 (90%) |
| Baseline to allow later assessment of treatment response | 25 | 24 | 22 | 71 (77%) |
| Plan radiotherapy | 12 | 14 | 21 | 47 (51%) |
| Differentiate between residual tumour and haemorrhage | 16 | 13 | 14 | 43 (47%) |
| Differentiate between residual tumour and post-operative enhancement | 15 | 11 | 14 | 40 (43%) |
| Differentiate between residual tumour and post-operative ischaemia | 14 | 13 | 10 | 37 (40%) |
| Establish amount of residual tumour suitable for further resection | 12 | 14 | 10 |
