About this study
Official title: ECHOQUALITY2: Maternal and Fetal Characteristics Influencing Image Quality in Prenatal Ultrasonography
The objective of this observational study is to identify maternal and fetal characteristics that impact image quality in prenatal ultrasonography. The investigators have assembled a retrospective cohort of 198 patients, each contributing three ultrasound images taken between 18 and 18 weeks and 6 days of gestation. For each image, the investigators assess the quality of two distinct elements as well as the overall image through both subjective and objective evaluations.
The primary questions the study seeks to address are:
What maternal and fetal characteristics influence image quality in prenatal ultrasonography?
- Conditions
- Ultrasonography, Obstetrics, Fetus, Pregnant Women

- Quality
What is being measured
The primary outcome is the main question the study is designed to answer.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maternal and fetal characteristics can influence quality image in ultrasonography (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Feb 2024.
