The goal of this study has been to develop a numerical model of the aortic valve, to validate
it with in-vivo data and to computationally evaluate the effect of two types of aortic valve-…

Magnetic resonance imaging (MRI) is particularly well adapted to the evaluation of aortic
distensibility. The calculation of this parameter, based on the change in vessel cross-sectional …

Renal dynamic computed tomographic (CT) data for 16 patients with unilateral renal artery
stenosis were compared with those for 12 control subjects. Three patterns of perfusion were …

Multidetector-row electrocardiogram (ECG)–gated cardiac computed tomography (CT) will
probably be a major noninvasive imaging option in the near future. Recent developments …

Background We evaluated the accuracy of planar radionuclide angiography and different
count-based and space-based electrocardiogram (ECG)-gated blood-pool single-photon …

To evaluate the effectiveness of contrast harmonic (power Doppler imaging) as an ultrasonic
modality to quantify flow, an in vitro model of perfusion was studied using Optison™, a …

We present an unusual case of ruptured aneurysm of the left sinus of Valsalva discovered
41 years after a car accident. Echocardiography was a key element in establishing the …

Retrograde cardioplegia is relatively safe, with a rate of coronary sinus rupture of 0.6%. With
the advent of perioperative transesophageal echocardiography, it is now possible to detect …

To evaluate the potential of harmonic power Doppler to quantify perfusion using a continuous
infusion of contrast, two dialysis cartridges were perfused with different flow rates adjusted …

PURPOSE: To review the electron-beam computed tomographic (CT) findings in patients
with clinical endocarditis and suspected of having perivalvular pseudoaneurysms at …
