Integrative mid-trimester anomaly (IMTA) chart: a novel sonographic approach for syndromatic challenges (pilot study)

Abstract

Objective: To validate the use of the integrative mid-trimester anomaly (IMTA) chart, a novel chart that aims to increase sonographers’ ability to diagnose fetal syndromes and complex anomalies.Methods: This study was conducted between September 2014 and January 2015. Pregnant women who attended our hospital for fetal medicine consultation during the second trimester were recruited. The diagnosis was assigned by a qualified consultant. The research coordinator randomized women between two groups (each consisted of two sonographers with comparable experience) and each was then examined twice (once with and once without the chart). Supposed diagnosis, patient and sonographer satisfactions were reported.Results: Twenty five women were recruited. Their average age was 26.48 ± 4.49 years and gestational age at examination was 24.39 ± 6.39. There were 17 (68%) fetuses that had multiple anomalies. The duration of examination was comparable. However, patient and sonographer satisfactions were higher when the same women were examined with the chart (p < 0.0001). The accuracy of diagnosis was also significantly higher (p = 0.03).Conclusion: The IMTA chart seems to be a useful tool for novice sonographers that could increase their diagnostic accuracy and improve their patient and their own satisfaction.
