| Abstract: | This is a follow-up of 8 and 9 year old children of women who took part in two randomised controlled trials of routine ultrasonography during pregnancy. 2161 singletons were followed-up partly through a questionnaire to the parents and partly through information from health centres. The dominant hand of the child was assessed by ten questions. the chances of not being right handed were significantly higher among children who had been screened in utero than among control children (Odds ratio 1.32). No clear differences were found between the groups with regard to deficits in attention, motor control, and perception or neurological development in the first year of life. |

| Discussion: | The authors emphasise that routine ultrasonography is usually done between the 16th and 22nd week of pregnancy which is the important phase of brain development when neurones migrate towards their final destination. See entry 0181, 0185 and 0186. |
