Forensic radiography is an important field in forensic medicine, becoming increasingly important in the event of a mass fatality. Forensic radiography is important not only in identifying the identity of the victim but how they died, and perhaps even the location of the blast where relevant (Walsh et al, 2004). …

Download file to see previous pages Dental radiography is perhaps one of the most accurate sub-divisions of the field, because dentition is more likely to survive fire, bombings, flooding and a number of other elements part of mass fatalities, because dental enamel is one of the hardest surfaces in the body. Comparison radiography concerning dentition is 93% effective in identification in these areas (Walsh et al, 2004). The purpose of this paper is to look at the role of forensic dental radiography in investigations following mass fatalities, by examining the role of the radiographer in such investigations and how dentition can be used in a number of ways. The paper will also look at some of the moral and legal issues facing forensic radiographers (including dental specialists) when it comes to dealing with mass fatalities, and some of the ways around these problems. Current UK protocol and the legal and moral issues surrounding forensic medicine (including radiography) is also examined to further highlight some of the problems and limitations to these methods. This first section will outline some of the major definitions needed to tackle this problem. The literature review will systematically investigate each area identified in the aims, and the conclusion will bring together all the information to fully answer the question.
1.1 What is Forensic Radiography? Forensic medicine is recognised as the field of science which uses medical facts and knowledge to solve legal problems. Historically the ancient Egyptians were the first to apply medical knowledge to legal issues. Early civilisations understood the need to have an understanding of medic al knowledge to answer certain questions such as the age of a foetus, use of poisons, virginity and sterility, prognosis of wounds and cause of death. In the sixteenth century, new codes and laws were introduced which required testimonies from medical experts; this lead to forensic medicine becoming recognised as a separate discipline (Brogden et al, 1998). With the discovery of x-rays and their utilisation for medical imaging purposes, modern medicine has come a long way from the traditional methods of ascertaining causes of injury and death. ‘Forensic Radiography is the application of the science of diagnostic imaging to questions of law’ (International Association of Forensic Radiographers. IAFR 2008) and this information can be used in a multitude of ways. Traditionally, the cause of death is determined by surgical autopsy. This is invasive and results in evidence being destroyed or contaminated, and is particularly troublesome when the deceased has religious or personal preferences that require non-invasive techniques (Brogdon, 1998). The advancement of technology has meant that we are now able to perform virtual autopsies using CT, fluoroscopy, ultrasound and MRI, as well as gaining important information from the more traditional X-ray (Brogdon, 1998). These are better suited as cultural sensitivities and ethical issues are not raised due to what some might say is desecration of the deceased (G Rutty et al, 2007). 1.2 The purposes of Forensic Radiography Forensic Radiography can be used to: • Determine the mechanism of injury or death. • Locate foreign bodies e.g. bullets, fragments of glass, and shrapnel. These may also be useful in identification of individuals, particularly in the case of dental metallic fragments present in the ante-mortem state. • Gather evidence for court. In cases of a crime scene, post mortem examinations are performed with the assumption of a criminal prosecution. (C Milroy 2005) • Identify the deceased by comparing ante-mortem and ...Download file to see next pagesRead More

Pediatric Radiography

...age of diagnosis of scoliosis was 10.6 years. With a radiographic followup continuing over an average of 40.1 years, it was concluded that this magnitude of exposures has resulted in increased incidence of breast cancers in these groups6. This proves that there is an increased risk of incidence of breast cancers with increased exposure to diagnostic radiation for scoliosis. Similar studies involving prenatal x-rays have been associated with increased risk of leukemia. This indicates that there is a necessity to minimize radiation exposure to the breast and bone marrow in the investigations of diseases would be a matter of particular concern in pediatric radiography. It has been found that the age at...

...(Souviron, 2005, p. 605). This process is helpful in gathering trace evidences even when the corpse has undergone postmortem changes already. The most precise manner in gathering dental records is dental radiography, which involves dental x-ray. As the tooth enamel is the hardest part of the human body, it can exist for long periods enabling pathologists to derive sufficient amount of information using dental records. Additionally, each person has a unique dental formation and structure allowing forensic pathologists to identify a specific person using dental records as well as determine the cause and...

Radiography Skills

...Radiography Skills Radiography Skills What view would you take if you want to know if a shoulder dislocation is anterior or posterior? A shoulder is said to have dislocated when the humerus head gets out of the glenoid cavity. Anterior dislocations are more common than the posterior dislocations. One can use different views to view the different dislocations. AP (Anteroposterior) views and Y-view images have to be acquired to determine both the anterior and posterior dislocations. The AP view will indicate the occurrence of an anterior dislocation while an inverse sign of Hill-Sach will show occurrence of posterior dislocation. On the other hand, the Y-view image will indicate a cut or an injury of the...

...procedure. The 28 days rule is important in radiation protection for pregnant women because it guards against any forms of uncertainty of giving radiography services that could possibly result in fatalities for early foetuses. The 28 days rule is however applicable for cases of pelvic and abdominal examinations (Hart D, et al., 2006). The Royal College of Radiologists (2012) also observe that the 28 days may be applicable for cases of computer tomography and barium enema. Once these procedures are followed, potential harm against the foetus is avoided. References Hart D, et al. (1996). Doses to Patients from Medical X-ray Examinations.
