NCT06343974

Brief Summary

The goal of this observational study is to compare fetal liver ultrasound radiomics between pregnancies complicated by type 1 diabetes and healthy controls. The main questions it aims to answer are:

  • Are fetal liver ultrasound radiomic features reproducible?
  • Does fetal liver ultrasound radiomics differ between pregnancies complicated by type 1 diabetes and healthy controls? Participants will undergo ultrasound examination to collect ultrasound data for the analyses.

Outcome Measures

Primary Outcomes (1)

  • Fetal liver ultrasound texture

    Fetal liver ultrasound texture is the collection of radiomic features that are extracted from the fetal liver ultrasound picture. The ultrasound pictures are acquired using transabdominal ultrasound. The radiomic features are extracted using conventional radiomics libraries e.g. pyradiomics.

    34+0 - 34+6 weeks of gestation

Secondary Outcomes (17)

  • Birth weight in grams

    After delivery, up to 24 hours

  • Birth weight centile

    After delivery, up to 24 hours

  • Large for gestational age (LGA)

    After delivery, up to 24 hours

  • Interventricular septum (IVS) width

    34+0 - 34+6 weeks of gestation

  • Number of pregnancies with neonatal hypoglycemia

    During initial hospitalization, up to one week of age

  • +12 more secondary outcomes

Study Arms (2)

Type 1 diabetes

Pregnant woman with type 1 diabetes.

Healthy controls

Pregnant women with uncomplicated pregnancy and normal oral glucose tolerance test (OGTT).

Healthy VolunteersYes
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Pregnant women will be recruited at Turku University Hospital and Turku maternity welfare clinics during their routine pregnancy follow-up.

You may qualify if:

  • Age between 18-45 years
  • Capable to give an informed consent
  • Singleton pregnancy
  • Planning to deliver in Turku University Hospital
  • Maternal BMI \< 40
  • Gestational age should be confirmed by first trimester ultrasound
  • Normal oral glucose tolerance test (OGTT) at 24-28 gestational weeks in controls

You may not qualify if:

  • Major fetal chromosomal, genetic, or structural anomaly
  • Fetal growth restriction, or birth weight \< 10th centile
  • Birth weight \> 90th centile or polyhydramnios in the controls
  • Non-reassuring fetal status requiring immediate treatment, or intrauterine fetal demise
  • Verified fetal infection (e.g. cytomegalovirus, toxoplasma, hepatitis B and C), excluding bacterial infection due to intrapartum chorioamnionitis
  • Placenta accreta spectrum disorder
  • Major maternal medical condition requiring systemic pharmacological treatment, other than non-severe hypertension, hypothyroidism, asthma, mild psychiatric disorders, etc.
  • Alcohol or tobacco use, or substance abuse in pregnancy
