1.0 Introduction

This constitution aims to review the peer literature regarding several(prenominal) non-invasive imaging techniques used in the get a lineion of pulmonary embolism. A brief introduction to each modality will be included, followed by the portrayal of each modalitys aptitude to accurately diagnose pulmonary embolism.




In particular the paper will focus on CT angiography, Ventilation Perfusion lung see and MRI angiography.

Pulmonary embolism (PE) is a common and potentially fatal in the clinical setting. The condition has no particular signs or symptoms and its diagnosis relies on imaging techniques.

The ability of a modality to diagnose PE derives from factors such as: a) Sensitivity, Specificity, PPV, NPV of tests; b) the ability to detect smaller emboli more peripherally e.g. to the 4th or sixth pulmonary bifurcations; c) the inter-observer agreement on the presence or absence seizure of emboli within a chosen modality.

2.0 Plain Film Radiography

Findings for PE on a CXR are variable, from normal to abnormal. CXR May confront dilatation of Pulmonary vessels proximal to the embolism along with the collapse of distal vessels, often with a sharp cut-off. (Kumar 2010)

Abnormal CXR is useful to show pleural fluid secondary to pleuritis,...If you want to get a full essay, order it on our website: Orderessay
