Sentence examples for medium injection rate from inspiring English sources

There are publications that suggest that a higher iodine concentration provides superior enhancement characteristics, but theoretically this superior enhancement can also be achieved by an increase in contrast medium injection rate (iodine flux in grams of iodine injected per second = injection rate × concentration) [ 3, 4, 6– 9].

To prospectively assess whether bolus shaping to exponentially decrease the contrast medium injection rate leads to alteration in image validity or renal function.

The CT data should be acquired helically using a rapid IV contrast medium injection rate (e.g. 4 5 ml/s)[ 15, 16] and appropriate scan timing during the pancreatic parenchymal phase of enhancement[ 17, 18].

By tracing the vertical position of maximum advance of the fluidized pattern with time, the evolution of the fluidized pattern is characterized by two dynamic regimes, the pattern not reaching or reaching the injection orifice, respectively, using small and medium injection rates.

Intended contrast medium injection rates were always reached including the maximum injection rate of 6.7 ml/s.

While two different contrast medium concentrations were used, iodine flux and iodine dose were kept constant by adapting contrast medium volume and injection rate.

The steps followed for the numerical simulation are: (a) Input of primary parameters (e.g., geometry of reservoir, geometry of cells, properties of medium, properties of fluids, injection rate, applied current density, resistivity of water, time parameters).

Table 4 Peak flow rate for contrast medium injection based on access vein Location Flow rate Hand/wrist/venipuncture 1.5 mL/s Antecubital/forearm All power injection Central venous catheter* <2.5 mL/s Open image in new window Fig. 3 Graphs and tables from the power injector: pressure-time and flow rate-time graphs.

However, these maximum injection rates are above the injection rates used in our study for both the high and moderate concentration groups and data produced by the contrast medium injection pump confirm that the required injection rates were always reached.

Experimental results show that DBSS offers better performance than the best baseline selection strategy and improves the energy-delay product for medium and high injection rates; it is well suited for workload consolidation.

CT scanning was performed at 10 and 45 s after the start of contrast medium injection into the microcatheter at a rate of 2.0 2.5 ml/s.
