Cardiac fusion imaging with low-dose computed tomography using prospective electrocardiogram gating


Husmann, L; Valenta, I; Weber, K; Adda, O; Veit-Haibach, P; Gaemperli, O; Kaufmann, P A (2008). Cardiac fusion imaging with low-dose computed tomography using prospective electrocardiogram gating. Clinical Nuclear Medicine, 33(7):490-491.

Abstract

In a 66-year-old patient with prolonged episodes of chest pain, catheter angiography revealed total occlusions of the right coronary artery and the distal circumflex artery (CX) as well as 2 sequential significant stenoses in the proximal CX and one significant stenosis in the proximal left anterior descending artery (LAD). To identify the culprit lesions with their respective territory, noninvasive assessment of viability was performed by F-18 FDG positron emission tomography (PET) and fused with a low-dose computed tomography coronary angiography using prospective electrocardiogram gating. Fused PET/computed tomography coronary angiography images demonstrated a large scar in the inferior myocardium, corresponding to the total occlusion in the right coronary artery, viable myocardium in the territory of the CX, and infarcted scar tissue with partially preserved viability in the anterior myocardium, corresponding to the presumably recanalized lesion in the LAD. The patient was scheduled for revascularization of the lesions in the LAD and the CX to reverse dysfunctional but viable myocardial segments.

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.
