Application of the pulmonary embolism rule-out criteria (PERC rule) and age-adjusted D-Dimer in patients undergoing computed tomography pulmonary angiography for diagnosis of pulmonary embolism.

Background: Diagnosis of pulmonary embolism (PE) constitutes a challenge for practitioners. Current practice involves use of pre-test probability prediction rules. Several strategies to optimize this process have been explored.

Perilymphatic micronodular pattern as a manifestation of pulmonary amyloidosis on high-resolution computed tomography.

The term describes a group of diseases caused by the fibrillar deposit of poorly folded proteins in tissues with a secondary alteration of their function. Diffuse parenchymal lung disease associated with amyloidosis is rare and is most often diagnosed in autopsy. A 45-year-old male patient presented an acute episode of cough with mucoid expectoration.
