No one in the practice of medicine today can deny the incredible advances and impact that computed tomography has had on how we display anatomy and visualise pathology. We entered the 21st century with over 60 million CT studies a year in the USA - and that number climbing. Spiral or helical technology meant greater coverage in less time, and multiple scans related to contrast administration became standard. Increasing availability of CT scanners allowed increasing utilisation. The annual increase of approximately 10% in CT studies has occurred with only a 1% population increase. Of the 377 million diagnostic and interventional studies performed in the USA in 2006, 67 million were CT scans - yet these CT scans contributed 49% of all medical radiation dose.

Background. Over the past four years, Steve Biko Academic Hospital has been in the process of implementing and refining the use of a picture archiving and communications system (PACS). As part of a post-implementation refining process, it was necessary to evaluate user-perceptions in order to improve on good system qualities and correct flaws.
Aim. The aim of this study was to assess whether medical clinicians perceived PACS as a positive adjunct to training and teaching opportunities - specifically those opportunities related to radiological image viewing and interpretation as part of patient case discussions.
Method. Standardised questionnaires with 'free text' and 'option selection' questions were distributed to clinicians who, as part of their training, rotated at Steve Biko Academic Hospital (where a PACS is in place) as well as other teaching hospitals without a PACS. Between February 2009 and May 2009, approximately 400 questionnaires were distributed. As a result of constant academic rotations, leave schedules of medical staff and posts vacated, questionnaires could not be distributed to the entire target population that was estimated to be in the region of 550 medical clinicians (comprising senior medical students, interns, medical officers, registrars and consultants). Of the 400 questionnaires distributed, 189 completed questionnaires were returned. Completion of the questionnaires was voluntary and anonymous.
Results and conclusion. Although a PACS relates specifically to the archiving and retrieval of radiological images and reports, it became clear from the feedback received from medical clinicians (who are ward-based, theatre-based or clinic-based users of a digital system) that many other factors, such as lack of adequate hardware and sub-optimal personal IT proficiency, contributed to some of the negative PACS-related perceptions and 'lost teaching opportunities' reported. Negative comments specifically related to PACS as a training adjunct included the frustrations associated with PACS downtime (especially during the period in 2009 when many electrical power cuts were experienced nationwide, resulting in network interruptions) and slow image retrieval during peak work-flow times. The advantages of PACS as a positive training adjunct were highlighted in the areas of multi-site viewing and consultation, the possibility of image manipulation and measurement tools, and better overall image quality. Clinicians felt that their training experience was also enhanced because of better patient follow-up made possible by access to all previous radiological imaging of a particular patient. Of the clinicians who completed the questionnaires, 63.5% felt that the PACS at Steve Biko Academic Hospital contributed positively to their training by creating more overall learning opportunities than other training environments without a PACS.

Delayed post-surgical sepsis from Teflon felt : the diagnostic value of CT scanning, and a reminder for theatre staff : case reportSource: SA Journal of Radiology 15, pp 48 –50 (2011)More Less
We report on two patients with surgical site infections following the inadvertent use of Teflon felt for haemostasis in elective and emergency surgery. CT scanning was superior to plain radiography in demonstrating the foreign bodies to enable planning of further surgical treatment.

With the establishment of an international advisory board consisting of Joshua Farber, Jonathan Kruskal, Walter Kucharczyk and Pia Sundgren (see the Radioactive News section) who have undertaken to provide objective and constructive criticism of the SAJR, and more specifically concerning its content in relation to international work, the journal continues on the growth path that was largely catalysed by the co-operative initiative between the Radiological Society of South Africa (RSSA) and Philips SA. To place these developments in perspective, it is necessary to understand the scope of our professional society's commitment to continuing medical education (CME) in this country.
MRI imaging of vein of Galen malformations at Steve Biko Academic Hospital : a mini case series : pictorial essaySource: SA Journal of Radiology 15, pp 53 –55 (2011)More Less
Vein of Galen aneurysmal malformation (VOGM) is an arterio-venous fistula involving aneurysmal dilatation of the median prosencephalic vein of Markowski. Dilated arteries drain into a large midline venous pouch in the region of the quadrigeminal cistern. It is a rare condition and is demonstrated in less than 1% of cerebral vascular malformations at any age and up to 30% of paediatric vascular malformations. Associated clinical findings may include cardiomegaly, widened mediastinum, pulmonary oedema and cyanosis. Heart failure and cyanosis in infants almost always results from congenital heart disease, but systemic arterio-venous malformations are a rare cause for such a presentation and the diagnosis is often missed or delayed. The following is a discussion and presentation of MRI images of 4 patients with this rare condition who presented at Steve Biko Academic Hospital within a 2-year period.

Please refer to page 30 of the March 2011 issue of the SAJR (http://www.sajr.org.za/index.php/sajr/article/view/450/425) for the presentation details and radiographic images. We congratulate Dr Himal Gajjar (Schnetler, Corbett and Partners, Cape Town) for the precise diagnosis, for which he receives an award of R1 000 from the RSSA. Professor Andronikou and Dr Els elaborate below on the condition and its radiological signs.
