Sentence examples for equal attenuation from inspiring English sources

Contrast-enhanced CT demonstrated lower attenuation than myocardium in 17 (81%) and equal attenuation in the remaining four; none of the lesions showed hyper-enhancement.

Although acting through different pharmacological mechanisms, the anti-platelet effect exerted by clopidogrel or aspirin was associated with roughly equal attenuation of arterial HDAC activity, thus demonstrating the crucial role played by platelet activation on this parameter.

It has been shown that when the decay rates into the three ports of the proposed device are equal, an attenuation between 0% and 100% can be obtained.

A typical pseudoaneurysm enhances in the arterial phase and washes out in the delayed phase; pseudoaneurysms are seen as focal, rounded regions equal in attenuation to the vessel or surrounding arterial structures on an arterial phase image [20].

They have attenuation equal to or less to that of muscle and often have internal regions of low attenuation corresponding to areas of necrosis [7] (Fig. 2a, b).

CT appearances that have been described include a well-defined lesion with tissue attenuation equal to or slightly higher than that of skeletal muscle.

Aligned positions ensure a constant (very large) difference between signal levels received from cells in different floors, equal to the attenuation between floors (i.e., FL=17 dB in Table 1).

Indeed, counting a voxel with a CT attenuation equal to 0 or +500 HU has the same significance as a lung area with a mean CT attenuation close to 0. The amplitude of the increase in lung tissue was variable from one patient to another, depending on the relative importance of the artifactual increase in lung density and the true increase in extravascular lung water.

We introduce a reference distance for which the free space attenuation equals.

This leads to signal voids translating into artifactual attenuation values equal to air in the proximity of the implants.

Furthermore, in order to approach the in-vivo situation as close as possible, contrast fluid and fat were used, with CT attenuation values equal to those in-vivo.
