The YEARS study provides a high level of evidence that a new, simple diagnostic algorithm can reliably and efficiently exclude PE and decrease the need for CTPA by 14% (absolute difference; 95% CI, 12-16) when compared with using the Wells' rule and fixed D-dimer threshold of < 500 ng/mL.

In our case for example, semiological features of pulmonary infarction on CT were difficult to interpret, leading to a complicated diagnostic algorithm. Ground-glass attenuation can precede typical segmental consolidation and is suggestive for incomplete pulmonary infarction, but may be confused with inflammatory pulmonary lesions.

In December 2012, by way of preparation, a PE diagnostic algorithm was distributed to all hospital clinicians, outlining the combined role of the validated modified Wells score (Table 1) and the quantitative D-dimer test in defining the pre-test probability of PE (Fig.

Many authors recommend doing ultrasound and diagnostic cystoscopy, with or without contrast studies, as initial diagnostic studies for microscopic hematuria.[sup.4,5] Many studies[sup.6,7] have shown that computed tomography (CT) urography, very frequently, miss lesions smaller than 1 cm, that is why cystoscopy should be a part of the initial diagnostic algorithm.

South Africa, one of the high-burden countries, has adopted these tests in the TB diagnostic algorithm. In other countries lack of diagnostic capacity has hampered the effective response to these improved TB assays.
