[Q]: Our objective was to evaluate the diagnostic value of computed tomography angiography (CTA) and ventilation perfusion (V/Q) scan in the assessment of pulmonary embolism (PE) by means of a Bayesian statistical model. Wells criteria defined pretest probability. Sensitivity and specificity of CTA and V/Q scan for PE were derived from pooled meta-analysis data. Likelihood ratios calculated for CTA and V/Q were inserted in the nomogram. Absolute (ADG) and relative diagnostic gains (RDG) were analyzed comparing post- and pretest probability. Comparative gain difference was calculated for CTA ADG over V/Q scan integrating ANOVA p value set at 0.05. The sensitivity for CT was 86.0% (95% CI: 80.2%, 92.1%) and specificity of 93.7% (95% CI: 91.1%, 96.3%). The V/Q scan yielded a sensitivity of 96% (95% CI: 95%, 97%) and a specificity of 97% (95% CI: 96%, 98%). Bayes nomogram results for CTA were low risk and yielded a posttest probability of 71.1%, an ADG of 56.1%, and an RDG of 374%, moderate-risk posttest probability was 85.1%, an ADG of 56.1%, and an RDG of 193.4%, and high-risk posttest probability was 95.2%, an ADG of 36.2%, and an RDG of 61.35%. The comparative gain difference for low-risk population was 46.1%; in moderate-risk 41.6%; and in high-risk a 22.1% superiority. ANOVA analysis for LR+ and LR- showed no significant difference (p=0.8745, p=0.9841 respectively). This Bayesian model demonstrated a superiority of CTA when compared to V/Q scan for the diagnosis of pulmonary embolism. Low-risk patients are recognized to have a superior overall comparative gain favoring CTA.
[A]: What can be predicted with the Wells criteria?


[Q]: Do you prefer British English or American English? Here are opinions from our readers. Andy: Well, being in British for 3 years now from New Zealand I've come to realize that a lot of British people pronounce words how Americans do. But in saying that, I guess the more educated British people do not pronounce words the way some Americans do. So, I prefer Educated British English. Bill: Well, I am studying English and I think British sounds funny and I prefer Americans sounds. Although I can tell that everyone else in my class loves British pronunciation and thinks American English is less pretty or even ugly. I don't agree at all, though. Cindy: At first British English accent sounds better and wonderful but then it gets annoying, so I love American English. Dale: I prefer the British accent. It sounds like someone reading a poem. I just like the pronunciation of the British people, very clear and sounds like music! British accent is more musical. Edward: When I listen to the BBC announcers, I notice that they're exploding the letters out, not pronouncing them. And some British people from the North of England or Scotland speak with strange accents. I mean it is difficult to understand their English. Frank: As a matter of fact, English for International Communication is very much like American accent. I love the American accent.
