Abstract

An interactive real-time imaging system capable of rapid coronary artery imaging is described. High-resolution spiral and circular echo planar trajectories were used to achieve 0.8 x 1.6 mm2 resolution in 135 ms (CEPI) or 1.13 x 1.13 mm2 resolution in 189 ms (spirals), over a 20-cm FOV. Using a sliding window reconstruction, display rates of up to 37 images/sec were achieved. Initial results indicate this technique can perform as a high-quality 2D coronary localizer and with SNR improvement may enable rapid screening of the coronary tree.

Interactive educational diabetes/insulin tutorial at www.2aida.info.

The World Wide Web now hosts a multitude of diabetes educational materials in various formats. Of particular interest is the diabetes/insulin tutorial available at the AIDA Website (accessible directly at: www.2aida.info). The tutorial combines textual or "static" information with an interactive diabetes simulator-AIDA online-to provide an engaging and effective educational tool. AIDA online (accessible directly at: www.2aida.net) enables the simulation of plasma insulin and blood glucose levels from user-defined insulin injection and carbohydrate intake data. A haemoglobin A1c value is also computed, giving an indication of overall blood glucose control in the virtual patient with diabetes. The diabetes/insulin tutorial is currently composed of four sections: the first two cover in considerable depth insulin injection regimens and insulin dosage adjustment; the third section introduces the principles of carbohydrate counting and, specifically, matching insulin doses to carbohydrate intake; and the fourth section illustrates the relationship between blood glucose levels and renal excretion of glucose. The simulator runs alongside the tutorial, and allows various concepts described in the text to be explored freely by the user and simulated interactively. This introduces a novel way of learning how injected insulin and dietary carbohydrate interact in various insulin injection regimens. A fifth section- for which any offers of assistance would be gratefully received-is planned. This will consider the use of insulin pumps and rapidly acting and very long-acting insulin analogues. Further improvements that may strengthen the existing tutorial and/or use of the online simulator are discussed in this column.

[Electronic learning: interactive learning in medicine or Socrates in electronic guise].

E-learning has been widely used for training in different fields. More recently, it was introduced during medical studies or for continuous medical education. The Canadian Universities are pioneers in e-learning creating special departments dedicated to pedagogy. Developing countries like Brazil or Central Europe have made some pilot experiments, which were successful. Several electronic companies have given a free access to the programmes and sites. The use of electronic media leads to an adaptation of teaching methods making them more interactive.
