AIM: To ascertain the level at which intervertebral disc degeneration of the cervical spine most commonly occurs in each decade from 20-79 years. MATERIALS AND METHODS: Using computer analysis, we retrospectively assessed the mean signal intensity from each cervical disc from T2-weighted spin-echo images in 60 symptomatic patients (10 per decade from the third to eighth inclusive). RESULTS: Age, disc level and interaction between age and level were highly significant predictors for the magnetic resonance imaging (MRI) mean signal intensity from intervertebral discs (p<0.0001 for all three terms). The MRI signals were generally lower as age increased and also for the higher discs (C2-C3, etc). CONCLUSION: In our study we have shown that in younger patients the higher discs are more frequently affected by degeneration than the lower ones. As age increases, the process of degeneration becomes more generalized with less variability between discs.

The objective of this study was to assess agreement between General Practitioners (GPs) and Consultant Radiologists as to whether a radiation exposure is justified and whether a request conforms to the Royal College of Radiologists (RCR) guidelines. Three GPs and three Consultant Radiologists were asked to review 100 requests for plain film imaging from GPs and to state whether the request justified a radiation exposure and whether the request conformed to RCR guidelines. It was discovered that there is greater agreement between radiologists than between GPs; this is a consistent pattern. The best agreement was between two Consultant Radiologists using the RCR guidelines. The poorest was between GPs using the request form details. It is suggested that the guidelines should be symptom-based to improve efficacy.
