Background and study aims
There is a need to improve the accuracy of the 18-20 week fetal ultrasound scan. This is because current technologies and screening methods do not pick up all of the abnormalities that could be detected. It is important to be able to spot any potential problems with the fetus (baby) before he/she is born. Making a diagnosis prenatally (before a baby is born) allows the expectant parents to make informed choices about whether or not to continue with the pregnancy. It can also improve a baby’s prospects by allowing a treatment plan to be produced from the moment the baby is born. We would like to improve ultrasound scanning so that in the future all babies have the best outcome possible.
Who can participate?
Adult women (at least 18) who are between 18-24 weeks pregnant.
What does the study involve?
Ultrasound data from the routine 20 week scan from willing participants are saved to use for research to help us improve ultrasound scanning in the future. The scan itself is performed exactly as usual but instead of only a selection of snapshots of the baby being recorded, as is usually the case, the data from the whole ultrasound recording from the scan is saved and retained for this research study. Participants choosing to take part in the second part of the study have additional ultrasound images of their baby performed. The data is used the data to teach our new imaging system the best way to capture high quality images. We would also like to collect as many images as we can to build a database of the baby’s body which computer programmes can use to compare with new ultrasound images. In this way we hope to be able to automatically detect different fetal organs and diagnose whether or not they are developing normally. Most women taking part in the study will have their research ultrasound and MRI scan on the same day. If they prefer, it may be possible for them to have the research ultrasound scan and the MRI scan a few days apart from each other.
What are the possible benefits and risks of participating?
If the participant is just having the data from their routine 20 week scan recorded there are no direct benefits to them. However, in the future we hope that the information gained from the study will lead to better antenatal diagnosis of fetal abnormalities and be used in all antenatal clinics nationally. Participants taking part in the additional research scans will be given a copy of the MRI scan of their baby, including a short video (cine) of their baby, and may also be given a 3D ultrasound picture. The fetal ultrasound has no perceived risks. We have thoroughly investigated all known potential risks to the baby and to the best of our knowledge and that of the medical community there are no additional risks to the baby or long-term effects of having the MRI scan. In addition, the MRI scan is not believed to have hazards associated with it when operated within National Radiological Protection Board Guidelines (which we do).
Where is the study run from?

| Scientific title | A computer-guided Imaging System for prenatal screening and comprehensive diagnosis of fetal abnormalities |
| Study objectives | Prenatal diagnosis of congenital abnormalities has become increasingly important. Making a diagnosis during fetal life permits expectant parents to make informed choices about the continuation of pregnancy. Prenatal diagnosis of some abnormalities can also improve fetal prognosis by allowing a treatment plan to be produced. This will enable access to specialist units and appropriate treatments from birth, rather than having a baby born that is severely ill and does not have a clear diagnosis or treatment plan. Currently, screening for fetal abnormalities by ultrasound takes place at 12 weeks and 18-20 weeks. The 12-week scan is focused on looking for markers of chromosomal abnormality rather than structural abnormalities, because the fetus is small and anatomical structures are not fully developed. Although anatomical structures are developed at the 18-20 week scan, it can sometimes be difficult to obtain clear images, for instance if the fetus is in an unfavourable position. Ultrasound is a powerful tool in fetal imaging. It is inexpensive, safe and portable, and images are acquired in real-time. Ultrasound passes sound waves into the body to create pictures from their reflections. It is commonly used to see if babies in the womb are healthy. Although every pregnant mother in the country has a scan at around 20 weeks, many of the babies who have problems are not picked up on these ultrasound scans. This is because scanning requires significant expertise which is difficult to have present in every hospital. We are proposing new technologies that allow scanning to be carried out not just with one probe (the device which takes the ultrasound picture) but up to four probes that can be used at the same time, and which move automatically to the right place to get the best pictures. This will mean we get a detailed picture of the whole baby which can then be analysed in an automatic way using advanced computer technologies to ensure we do not miss babies with potential problems. This should mean a high quality scanning service across the country and fewer babies who have major problems will be missed. |

| Health condition(s) or problem(s) studied | Our aim is to improve prenatal diagnosis rates for fetal abnormalities |
| Intervention | We will gather ultrasound and some MRI data from pregnant ladies at the time of their anomaly scan (18-24 week's gestation) and use this to develop computer aided diagnostics, build fetal atlases and develop a multi-transducer ultrasound system to automate fetal anomaly detection and improve the rates of their diagnosis. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure | The data from up to 20,000 routine anomaly scans performed at 18-21 week's gestation will be collected. |
| Secondary outcome measures | Ultrasound and MRI imaging data will be used in combination with information on image labelling and image acquisition (transducer position and pressure sensing) obtained at 20-25 week's gestation. |
