Clinical outcomes after magnetic resonance angiography (MRA) versus computed tomographic angiography (CTA) for pulmonary embolism evaluation

Magnetic Resonance Angiography (MRA)

Table of

Spiral computed tomographic scanning and magnetic resonance angiography for the diagnosis of pulmonary embolism.

PURPOSE To compare prospectively the accuracy of spiral computed tomography (CT) with that of ventilation-perfusion scintigraphy for diagnosing pulmonary embolism. MATERIALS AND METHODS Within 48 hours of presentation, 142 patients suspected of having pulmonary embolism underwent spiral CT, scintigraphy, and (when indicated) pulmonary angiography. Pulmonary angiography was attempted if interp...

Clinical Outcomes After Evaluation of Stable Chest Pain by Coronary Computed Tomographic Angiography Versus Usual Care

Meta-analysis: outcomes in patients with suspected pulmonary embolism managed with computed tomographic pulmonary angiography.

BACKGROUND Spiral computed tomographic pulmonary angiography (CTPA) is increasingly being used in the evaluation of patients with clinically suspected pulmonary embolism (PE). However, CTPA as a definitive diagnostic test may be limited by inadequate sensitivity, especially in instances of isolated subsegmental emboli. PURPOSE To assess the safety of withholding anticoagulation in patients wi...

The Contest Between Magnetic Resonance and Computed Tomographic Coronary Angiography

Noninvasive coronary imaging is often considered the Holy Grail among cardiologists and radiologists interested in the diagnosis and treatment of coronary atherosclerosis.1–3 That noninvasive coronary imaging would aid in establishing new prevention and treatment strategies in a wide range of clinical scenarios, ranging from early subclinical diagnosis of atherosclerosis in asymptomatic individ...
