Magnetic Resonance Imaging Autopsy Study
An observational study of Stillbirths and Sudden Infant Death, run by Thayyil, Sudhin at 2 sites in United Kingdom.
Trial summary
The aim of this project is to establish whether magnetic resonance (MR) imaging can provide a minimally invasive approach for post-mortem assessment of the fetus, infant and child, with similar detection rates for anomalies and determination of the cause of death. Read more about this study

- Ages Up to 18 years
- All sexes
- No healthy volunteers
- Child, Adult
Study population: This study will be performed across two hospital sites: Great Ormond Street Hospital for Children (GOSH) and University College London Hospitals (UCLH). Both of these hospitals are associated with a single academic institution - University College London (UCL). Consecutive fetuses, newborns and children referred for autopsy at these two hospitals will be eligible for recruitment. All recruited cases will have conventional post-mortem MR imaging at 1.5 Tesla and conventional autopsy. CT imaging will be performed in suspected traumatic injuries and skeletal dysplasias.
Who may be able to join
- Fetuses, newborns and Infants undergoing conventional autopsy
Who cannot join
- Lack of parental consent

About this study
Official title: Post Mortem Magnetic Resonance Imaging in the Fetus, Infant and Child: A Comparative Study With Conventional Autopsy
The aim of this project is to establish whether magnetic resonance (MR) imaging can provide a minimally invasive approach for post-mortem assessment of the fetus, infant and child, with similar detection rates for anomalies and determination of the cause of death.
This will be achieved by acquiring a database of whole-body, post-mortem MR images in approximately 400 fetuses, infants and children, over a 3 years period. Images will be acquired on a dedicated 1.5T research MR scanner. MR images will be reported by an expert group of paediatric radiologists, and compared, in a blinded fashion, with reports from conventional autopsy performed by expert perinatal and paediatric pathologists. Importantly, the post-mortem information will be assessed with reference to the needs of the parents, referring clinicians and HM Coroners. The detection of central nervous system abnormalities will be assessed separately.

The study will be performed across two sites: A dedicated children's hospital (Great Ormond Street Hospital) and a teaching hospital, with large obstetric, fetal and neonatal departments (University College London Hospital), which are linked academically by University College London.
Co-ordination of the project will be managed by a steering committee, which will ensure accurate collation and comparison of the data.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.

|---|---|---|
| Fetuses | Still birth and Termination of pregnancies | |
| Children | Includes Newborns, Infants and Children |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of cases where the cause of death and/or major pathological lesions are detected
Conventional autopsy will be considered as the gold standard. The number (%) of cases where post-mortem MR imaging identifies the cause of death and/or major pathological lesions when compared with conventional autopsy will be reported
Measured: 6 weeks
Secondary outcomes (2)
MR appearance of death-induced artefacts.
The common artefacts seen on post-mortem MR imaging will be described
Measured: 6 weeks
Number of cases where there is a change in ante-mortem diagnosis
Number of cases where there is a change in ante-mortem diagnosis following post-mortem MR imaging will be reported
Measured: 6 weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The aim of this project is to establish whether magnetic resonance (MR) imaging can provide a minimally invasive approach for post-mortem assessment of the fetus, infant and child, with similar detection rates for anomalies and determination of the cause of death.
This will be achieved by acquiring a database of whole-body, post-mortem MR images in approximately 400 fetuses, infants and children, over a 3 years period. Images will be acquired on a dedicated 1.5T research MR scanner. MR images will be reported by an expert group of paediatric radiologists, and compared, in a blinded fashion, with reports from conventional autopsy performed by expert perinatal and paediatric pathologists.

Questions about this trial
What is this clinical trial studying?
An observational study of Stillbirths and Sudden Infant Death, run by Thayyil, Sudhin at 2 sites in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Number of cases where the cause of death and/or major pathological lesions are detected (time frame: 6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01417962, which also lists 14 linked publications.
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 22 Apr 2013.
