Chairpersons' introduction (Part 1)
A. Dominguez; Lausanne/CH
Learning Objectives

1. To provide insights into the role of imaging, and radiographers, in forensic imaging.
2. To appreciate the key aspects of a quality forensic imaging service using angiography.
3. To understand the challenges associated with forensic imaging.

Abstract

The implementation of radiographers in forensic medicine is becoming more and more widespread. The use of the technical skills of a radiographer increases the quality of services, especially in the field of postmortem imaging angiography. The multi-disciplinary collaboration between pathologists, the radiologists and the radiographers allows the implementation of these new practices. Thanks to the contribution of forensic imaging, the sensitivity of the post-mortem examination within medico-legal investigations are increased.

Abstract

Forensic Radiology is a segment within the field of medical imaging that focuses on using radiology imaging techniques where evidence may be gathered in a court of law. The use of radiography in support of evidence has a long history dating back to the first few months after Wilhelm Roentgen's discovery in 1895. A bullet seen using an x-ray was used for cases of attempted murder. Pathologists commonly use radiographs when performing autopsies. The images can help them identify elements that are out of place or questionable and then allows them to investigate further. As the radiologic sciences have advanced over the years to include MRI's, CT's, and ultrasound, the accuracy has increased to a much greater degree and has made it even more relevant for investigating crimes and gathering evidence.

A. The chain of evidence
M. Davis; Dublin/IE
Learning Objectives

1. To appreciate the importance of continuity of evidence and record keeping.
2. To learn about essential steps for radiographers to follow.
3. To discuss potential pitfalls when conducting forensic examinations.

Abstract

Diagnostic imaging is a useful tool for and clinical case management. Radiographers by the nature of their work create material which can be potentially used as evidence. This material may be in a variety of formats. It is important that radiographers maintain continuity of evidence within their working practices as the material, may be used by other professionals as part of their decision-making process as well as the courts including both the child and family and criminal courts. The presentation will draw upon examples and discuss potential pitfalls in this area.

B. Post-mortem cardiac angiography
H. Precht; Odense/DK
Learning Objectives

1. To learn about the development of multiphase post-mortem cardiac angiography (MPMCCTA).
2. To appreciate the benefits and limitations of MPMCCTA examinations.
3. To understand the role of the radiographer in the MPMCCTA.

Abstract

Computed Tomography (CT) is a widely used imaging tool with high diagnostic accuracy and prognostic value. Cardiac CT Angiography (CCTA) scanning is often used to diagnose cardiology patients as coronary atherosclerosis is a worldwide disease and counts for millions of deaths every year. The CT technology is developing rapidly given new possibilities for optimisation. A CCTA scan can identify elements as coronary stenosis, coronary atherosclerotic-, low attenuation- and spotty calcification plaques, positive remodelling. These components have been considered as important features of coronary plaque vulnerability and instability. As the coronary arteries have an average diameter of 1-4 mm, the CCTA images need to image small details with low attenuation. The CT scanner is challenged to image small details with good contrast and temporal resolution; therefore optimisation of the CT protocol is necessary. New developed CT techniques need to be implemented with caution to ensure the images not change coronary plaques size or content inappropriate. To evaluate new CCTA technique influence of coronary plaques, a correlation with the gold standard of histopathology could give us useful information. To be able to reflect these results to in-vivo CCTA it is important to prepare the heart and arteries with correct pressure, contrast filling in the arteries as contrast/water in the heart chambers. Scattered radiation from the surrounding tissue needs to be included as the most challenging parts is an exact procedure for three-dimensional alignment procedure for PMCCTA and the histopathology data.

C. Paediatric forensic imaging
A. L. Brookes; Fulwood/GB
Learning Objectives

1. To appreciate the role of the radiographer in paediatric forensic imaging.
2. To understand the challenges associated with conducting paediatric forensic examinations.
3. To discuss the imaging options available for paediatric forensic imaging.

Abstract

Forensic imaging is the application of any form of diagnostic radiography to the law and is used to provide evidence for a potential criminal investigation. This sub-speciality of radiology is ever expanding, and recent developments have seen forensic imaging utilised and researched more widely, particularly the use of CT in post-mortem settings. Paediatric forensic imaging is the mainstay of routine forensic cases undertaken in imaging departments. Most often, this is the investigation of Suspected Physical Abuse (SPA) in both living and deceased children. In these cases, imaging is used as an adjunct to other evidence collected in the detection of SPA. However, recognition and further prevention of child abuse can be achieved through the use of radiological findings. Nevertheless, forensic imaging in paediatrics extends beyond use for detection of SPA, and in almost all types of forensic imaging, paediatric cases will be found.
