Conventional and Computerized Tomography are radiological techniques with the objective to reproduce tomographique images, both with different features with regard to detail recognition. Both techniques can be considered as methods complementing one another and not as competitive ones following the present stage of development and experiences gained in this field. Conventional Tomography with its proper range of application is regarded as a fully developed technique, whereas Computerized Tomography will possibly allow further development and improvements with regard to technology and performance. The limits, however, in the relation price/performance regarding tomopgraphic equipments and the relation dosage/image quality regarding the method can already be recognized. If we compare both techniques, we may say, however, with certain reservations, that Conventional Tomography stands out for a superior spatial resolution whereas a better distinction between small density differences in tissues one of the most distinguished features is Computerized Tomography is known for.
