Sentence examples for concentration of contrast from inspiring English sources

According to Equations 1 and 2, signal intensities change with T1, T2, and the concentration of contrast agents.

As depicted in Fig. 2, Au/PAMAM had a linearly increased enhancing effect on X-ray attenuation relied on the concentration of contrast agents.

The joint use of these two methods could therefore limit the concentration of contrast agents needed for the imaging, which could be beneficial to the patient.

Assuming a linear relation between the signal and the concentration of contrast agent, signal-time curves are converted to concentration-time curves [43].

If the intravascular concentration of contrast medium drops under the interstitial concentration level, diffusion takes place in opposite direction until all contrast is eliminated: this is called 'wash-out' [19, 20, 21].

After the first pass a decrease in concentration of contrast medium and signal intensity occurs by intravascular dilution, leakage into the tissues and renal clearance, resulting in a steady state.

A list of in vitro phantoms and their respective concentrations of contrast agents is shown in Supplementary Table S1.

Least mean squares linear material decomposition was used to calculate the concentrations of contrast agents in the aorta, renal cortex, renal medulla and renal pelvis.Using reference vials with known concentrations of materials, we computed molar concentrations of the various contrast agents during each phase of CT scanning.

K-edge digital subtraction angiography (KEDSA) combined with the tunability of synchrotron beam yields an imaging technique that is highly sensitive to low concentrations of contrast agents.

At the same time the otherwise increasing possibility of biochemical interferences using higher concentrations of contrast media could be avoided.

Higher concentrations of contrast, 350, 370, and even 400 mg I /ml, have been developed and are being employed clinically.
