A non-invasive medical scanning apparatus for generating an image of a fetus comprises means for detecting a quantitative measure relating to the fetal image; means responsive to the detected quantitative measure for generating a numerical value indicative of the shape of the fetal image; and means for detecting whether the numerical value lies in a predetermined range indicative of a possible fetal abnormality. The apparatus is particularly used to detect abnormality in the shape of the fetal head which may be indicative of spina bifida or of the nuchal fold which may be indicative of Down's Syndrome. |
