Diagnostic Radiology (diagnostic + radiology)
Selected AbstractsPerceptual error and the culture of open disclosure in Australian radiologyJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 3 2006AG Pitman Summary The work of diagnostic radiology consists of the complete detection of all abnormalities in an imaging examination and their accurate diagnosis. Errors in diagnostic radiology comprise perceptual errors, which are a failure of detection, and interpretation errors, which are errors of diagnosis. Perceptual errors are subject to rules of human perception and can be expected in a proportion of observations by any human observer including a trained professional under ideal conditions. Current legal standards of medical negligence make no allowance for perceptual errors, comparing human performance to an ideal standard. Diagnostic radiology in Australia has a culture of open disclosure, where full unbiased evidence from an examination is provided to the patient together with the report. This practice benefits the public by allowing genuine differences of opinion and also by allowing a second chance of correct diagnosis in cases of perceptual error. The culture of open disclosure, which is unique to diagnostic radiology, places radiologists at distinct medicolegal disadvantage compared with other specialties. (i) Perceptual error should be acknowledged as an integral inevitable part of diagnostic radiology; (ii) culture of open disclosure should be encouraged by the profession; and (iii) a pragmatic definition of medical negligence should reflect the imperfect performance of human observers. [source] Cancer risk from diagnostic radiology in a deliberate self-harm patientACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2010L. J. Norelli Norelli LJ, Coates AD, Kovasznay BM. Cancer risk from diagnostic radiology in a deliberate self-harm patient. Objective:, Patients who engage in recurrent deliberate self-harm (DSH) behaviours have increased morbidity and mortality and use emergency services more than others. Unrecognized iatrogenic injury may play a role. Specifically, we call attention to the potential danger of cumulative radiation exposure. Method:, Case presentation and discussion. Results:, A 29-year-old woman with multiple episodes of deliberate foreign body ingestion received over 400 diagnostic radiology examinations during a 12 year period. The patient's calculated total radiation dose reached an average of 20.5 mSv per year, a dose comparable to atomic bomb survivors and nuclear industry workers, populations in which there is a significant excess cancer risk. Conclusion:, Patients with recurrent self-injurious behaviours, frequent users of healthcare services who often undergo repeated medical assessment and treatment, are likely at higher risk for iatrogenic adverse events. Multiple diagnostic radiology examinations have recently come under scrutiny for causing increased lifetime risk of cancer. Healthcare providers, in particular psychiatrists and emergency department physicians, should consider the cumulative risks of radiological procedures when assessing and treating patients with DSH.

[source] Benign cysts in the central nervous system: Neuropathological observations of the cyst wallsNEUROPATHOLOGY, Issue 1 2004Asao Hirano A diverse variety of benign cysts exist in the CNS. Advances in diagnostic radiology have facilitated diagnoses and surgical intervention in many patients with CNS cysts. However, a fundamental understanding of the pathological features of these lesions is clinically vital. From an etiological point of view, the cysts can be divided into two groups. The first includes lesions that arise from within the CNS and may be static structures such as cavities arising from infarcts and other destructive processes while other lesions such as arachnoid cysts, ependymal cysts, cystic hemangioblastoma, cystic cerebellar astrocytoma and infectious processes, are progressive. The second group of cysts arise from the intrusion of non-nervous system tissue into the neuroaxis and are usually midline. They are frequently expanding congenital lesions although some become symptomatic only in adults. Examples include teratomas, dermoid cysts, epidermoid cysts, craniopharyngiomas, Rathke's cleft cysts, and other epithelial cysts presumably derived from the upper respiratory or intestinal tract. Chick embryos exposed to lead have been used as a model of cyst formation. [source] | ||||||||||
