Conference paper


The introduction of computerised tomography into clinical practice by AMBROSE and HOUNSFIELD in 1972 opened a new era in the diagnosis of soft-tissue tumours in the orbit. In a preliminary communication (1) the findings in the first 17 histologically proven primary tumours and granulomas examined by this technique were recorded. Progressive refinements in the apparatus (vide infra) and a 4-5-fold increase in the number of verified cases now allows a more mature assessment of C.A.T. scanning and its place in relation to other methods of orbital investigation.
