The role of cardiovascular magnetic resonance in patients presenting with chest pain, raised troponin, and unobstructed coronary arteries.
AIMS Troponin measurement is used in the assessment and risk stratification of patients presenting acutely with chest pain when the main cause of elevation is coronary artery disease. However, some patients have no coronary obstruction on angiography, leading to diagnostic uncertainty. We evaluated the incremental diagnostic value of cardiovascular magnetic resonance (CMR) in these patients. ...
متن کاملQuantification of acute myocardial injury by ShMOLLI T1-Mapping, T2-weighted and late gadolinium imaging in patients presenting with chest pain, positive troponins and non-obstructive coronary arteries
Methods 16 patients (8 men, mean age 51±16 years) with acute chest pain, Troponin I >1.0 ug/L and non-obstructive coronary arteries underwent 1.5T CMR imaging within 7 days of presentation (median 3 days). CMR protocol included Shortened Modified Look-Locker inversion recovery (ShMOLLI) for T1-mapping, T2-STIR and late gadolinium enhancement (LGE) imaging. Regional wall motion was assessed with...

متن کاملDiagnosis of acute myocarditis by cardiovascular magnetic resonance in a patient with chest pain, positive troponin, and normal coronary arteries.
rom the Cardiovascular agnetic Resonance Unit, oyal Brompton Hospital, ondon, United Kingdom. anuscript received arch 11, 2009, accepted arch 25, 2009. The finding of normal coronary arteries in patients admitted with chest pain and positive troponin is well recognized. Owing to its ability to provide tissue characterization, cardiovascular magnetic resonance imaging allows a diagnosis of myoca...
متن کاملThe diagnostic performance of non-contrast T1-mapping in patients with acute myocarditis on cardiovascular magnetic resonance imaging
Background The accurate diagnosis of acute myocarditis on cardiovascular magnetic resonance imaging (CMR) often requires multiple modalities, including T2-weighted (T2w), early and late gadolinium imaging. T1-mapping is an emerging technique which is also sensitive to acute changes in free water content. We hypothesized that non-contrast T1-mapping using the novel Shortened Modified Look-Locker...
