Audit of cranial computerised tomography in a general medical unit.

Over a two year period 108 patients had cranial computerised tomographic (CCT) scans while under the care of a general medical team. Sixty eight scans showed 70 abnormalities. Completed stroke, transient ischaemic attacks (TIA), epilepsy and headache were the most common indications for CTT while infarct, atrophy, haemorrhage and tumour were the most common abnormalities. Eight tumours were identified comprising 12% of epileptics and 9% of stroke patients.
