Abstract

A 68-year-old patient with known 3-vessel coronary artery disease, a history of aortocoronary bypass surgery, and presently without chest pain, was referred to myocardial perfusion imaging for preoperative risk assessment as infrarenal aortic aneurysm repair was planned. Single photon emission computed tomography (CT) revealed normal myocardial perfusion at adenosine-stress and at rest. However, the CT scan used for attenuation correction (AC) demonstrated a large tumor in the right upper lung as an incidental finding, and the patient was referred for staging with F-18 fluorodeoxyglucose positron emission tomography/CT and subsequently to thoracic surgery. The lesion was resected and diagnosed to be an adenocarcinoma (stage pT2, cN0, cM0). When last seen, the patient was recovering well from surgery.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
