Objective: Post-mortem computed tomography (PMCT) is an established method for disease, complications, and cause of death determination in both clinical and forensic cases. By adding intravascular infusion of contrast medium, computed tomography angiography (PMCTA) provides additional information on vascular structures and hemorrhages. When easily applicable and low in costs, this technique would be more frequently applied and of additional value to clinical and educational purposes, particularly in forensic scientific context. Materials and Methods: PMCTA was performed on 10 bodies of the anatomy department. First, a metal T-piece was inserted into the femoral artery as part of standard practice for conservation. Secondly, surplus contrast medium with sodium chloride was infused into the body through a catheter tube set attached to the metal T-piece, using a readily available enteroclysis pump from our radiology department. Results: With added costs of approximately € 266 (personnel and materials) and an additional procedure time of 15-20 minutes, successful infusion of contrast mixture was achieved with the enteroclysis pump. Partial or complete opacification was measured in 89% of arteries, with enhancement of soft tissue visualization. Conclusion: This study successfully evaluated an inexpensive and easy to use method to perform PMCTA for post-mortem investigations.

Diagnostic reference levels (DRLs) for medical x-ray procedures are being implemented currently in the Netherlands. By order of the Dutch Healthcare Inspectorate, a survey has been conducted among 20 Dutch hospitals to investigate the level of implementation of the Dutch DRLs in current radiological practice. It turns out that hospitals are either well underway in implementing the DRLs or have already done so. However, the DRLs have usually not yet been incorporated in the QAsystem of the department nor in the treatment protocols. It was shown that the amount of radiation used, as far as it was indicated by the hospitals, usually remains below the DRLs. A procedure for comparing dose levels to the DRLs has been prescribed but is not Always followed in practice. This is especially difficult in the case of children, as most general hospitals receive few children. Health Phys. 108(4):462–464; 2015

Medical imaging practice changed dramatically with the introduction of digital imaging. Although digital imaging has many advantages, it also has made it easier to delete images that are not of diagnostic quality. Mistakes in imaging—from improper patient positioning, patient movement during the examination, and selecting improper equipment—could go undetected when images are deleted. Such an approach would preclude a reject analysis from which valuable lessons could be learned. In the analog days of radiography, saving the rejected films and then analyzing them was common practice among radiographers. In principle, reject analysis can be carried out easier and with better tools (ie, software) in the digital era, provided that rejected images are stored for analysis. Reject analysis and the subsequent lessons learned could reduce the number of repeat images, thus reducing imaging costs and decreasing patient exposure to radiation. The purpose of this study, which was conducted by order of the Dutch Healthcare Inspectorate, was to investigate whether hospitals in the Netherlands store and analyze failed imaging and, if so, to identify the tools used to analyze those images.
