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.

Further study details as provided by Thayyil, Sudhin:

Primary Outcome Measures:
  • Number of cases where the cause of death and/or major pathological lesions are detected [ Time Frame: 6 weeks ]
    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

Secondary Outcome Measures:
  • MR appearance of death-induced artefacts. [ Time Frame: 6 weeks ]
    The common artefacts seen on post-mortem MR imaging will be described

  • Number of cases where there is a change in ante-mortem diagnosis [ Time Frame: 6 weeks ]
    Number of cases where there is a change in ante-mortem diagnosis following post-mortem MR imaging will be reported

Estimated Enrollment: 400
Study Start Date: March 2007
Study Completion Date: September 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Still birth and Termination of pregnancies
Includes Newborns, Infants and Children


Ages Eligible for Study:   up to 18 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
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.

Inclusion Criteria:

  • Fetuses, newborns and Infants undergoing conventional autopsy

Exclusion Criteria:

  • Lack of parental consent
