[Value of cardiovascular magnetic resonance in acute myocarditis].

Cardiovascular magnetic resonance imaging (MRI) demonstrates location, activity and extent of inflammation in acute myocarditis. A combined approach, using different imaging modalities (T2-IR-weighted imaging, early and late gadolinium enhancement) provides high diagnostic accuracy. The type of myocardial virus infection (PVB19, HHV6) may be related to the pattern of inflammation demonstrated by cardiovascular MRI and the clinical course.

Computed tomographic angiography findings in 103 patients following vascular events in the posterior circulation: potential and clinical relevance.

We studied the diagnostic value of computed tomographic angiography (CTA) in the posterior circulation as a noninvasive substitute for intra-arterial digital subtraction angiography (DSA). We prospectively investigated 103 patients with acute stroke in the posterior circulation. All patients underwent CTA and Doppler ultrasound, and DSA was performed in 22 patients.

Intracranial stenoocclusive disease: double-detector helical CT angiography versus digital subtraction angiography.

Background And Purpose: To our knowledge, no large-scale studies comparing the accuracy of CT angiography (CTA) to intraarterial digital subtraction angiography (DSA) of intracranial stenosis have been reported. We attempted to determine the diagnostic value of intracranial CT angiography (CTA) of normal vasculature and variants as well as of stenoocclusive disease.

Methods: One-hundred and twelve patients underwent CTA and intraarterial angiography, and 2205 vascular segments were examined to ascertain presence, visibility, and degree of arterial stenoses (n = 105) as well as anatomic variants.

[3-phase spiral CT of the liver, Value of non-contrast arterial and portal venous studies in the diagnosis of focal liver lesions].

Purpose: To assess the value of noncontrast, arterial and portal venous phase of triphasic helical CT in detecting and characterising focal liver lesions.

Material And Methods: 120 patients with focal liver disease underwent triphasic helical CT examinations with a collimation of 6.5 mm at a table feed of 6.
