Multislice spiral computed tomography of subacute myocardial infarction.
A62-year-old man presented to our emergency room with severe retrosternal pain. An ECG showed an acute lateral myocardial infarction, and the patient was referred for cardiac catheterization. One and a half hours after the onset of acute chest pain, coronary angiography revealed a thrombotic occlusion of the intermedial branch of the left coronary artery. Mechanical recanalization of the infarc...
متن کاملAssessment of myocardial edema by computed tomography in myocardial infarction.
OBJECTIVES The aim of this study was to analyze whether cardiac computed tomography (CT) permits the assessment of myocardial edema in acute myocardial infarction (MI). BACKGROUND Several studies proved the value of detecting myocardial edema from T2-weighted cardiac magnetic resonance (CMR) for differentiating acute from chronic MI. Computed tomography is suited for depicting MI, but there a...
متن کاملDiagnosis of acute myocardial infarction on computed tomography angiogram.
A 68-year-old white man, an active smoker with hyperten-sion and hyperlipidemia, presented to the emergency department with substernal chest pain. His chest pain began acutely 2 hours earlier, was described as intense pressure radiating to the back, 10/10 in severity with associated diaphoresis, nausea, and vomiting. Chest pain persisted despite sublingual nitroglycerin and subsequent intraveno...
متن کاملSpiral computed tomography for acute pulmonary embolism.
There is still considerable debate about the optimal diagnostic imaging modality for acute pulmonary embolism. If imaging is deemed necessary from an initial clinical evaluation such as d-dimer testing, options include nuclear medicine scanning, catheter pulmonary angiography, and spiral CT. In many institutions, spiral CT is becoming established as the first-line imaging test in daily clinical...
متن کاملElectrocardiogram-correlated image reconstruction from subsecond spiral computed tomography scans of the heart.
Subsecond computed tomography (CT) scanning offers potential for improved heart imaging. We therefore developed and validated dedicated reconstruction algorithms for imaging the heart with subsecond spiral CT utilizing electrocardiogram (ECG) information. We modified spiral CT z-interpolation algorithms on a subsecond spiral CT scanner. Two new classes of algorithms were investigated: (a) 180 d...
