Feb 14, 2008 · The flow rate and iodine delivery rate at P max were calculated using spreadsheet software (Microsoft Excel 2004 software, Microsoft Co. Ltd). The hydrodynamic theory and calculation method are summarized in the appendix. From the hydrodynamic viewpoint, the essence of the calculation is to assume the following two principles.Author: Teiyu Yamauchi, Shigeru Furui, Shigeru Suzuki, Kohshiro Mimura, Toshihiko Hayashi, Takeshi Yamada, C...

increased for CTA in a given patient, one can increase iodine concen-tration, the flow rate at which CM is injected, or both. The aforementioned considerations can be synthesized by the concept of iodine delivery rate (IDR), which is defined as: IDR ¼ ½I f ðEquation1Þ where [I] is the iodine concentration of CM and f is the flow rate at

Despite an increase in beam-hardening artifacts on iodine perfusion maps, the use of iopromide 370 at 4.0 mL/sec, providing an IDR of 1.4 gI/sec, results in superior subjective image quality of DE-CTPA and dual-energy iodine perfusion map images compared to protocols using a …Author: Jan Hansmann, Christian Fink, Gregor Jost, Hubertus Pietsch, Mathias Meyer, John W.

Apr 23, 2019 · To compare the effect of contrast medium iodine concentration on contrast enhancement, heart rate, and injection pressure when injected at a constant iodine delivery rate in coronary CT angiography (CTA). One thousand twenty-four patients scheduled for coronary CTA were prospectively randomized to receive one of four contrast media: iopromide 300 mg I/ml, iohexol 350 mg I/ml, …Author: Marco Rengo, Anoeshka Dharampal, Marisa Lubbers, Marc Kock, Joachim E.

Jun 01, 2004 · With the higher iodine concentrations, viscosity limited the injection speed of the achievable pressure limit. The highest iodine delivery rate was 2560 mg/s, using an agent with 320 mg/ml iodine content. With the more concentrated agent, a maximal …Author: Friedrich D Knollmann, K. Schimpf, R. Felix

The calculated iodine delivery rate (I cal) and calculated optimum iodine concentration (calculated C opt) were obtained with spreadsheet software. The agreement between I cal and I meas was studied by correlation and logarithmic Bland-Altman analyses. The value of the calculated C opt was within the optimum range of iodine concentrations

However, in these trials, contrast media were injected with unequal iodine delivery rates. By using an iodine delivery rate of 1.5 g of iodine per second in both arms (body weight < 100 kg), we measured average attenuation values well above 400 HU, with acceptable noise and image quality. The injection rate of iodixanol 270 was 5.6–6.5 mL/sec.Author: Marisa M. Lubbers, Marc Kock, André Niezen, Tjebbe Galema, Marcel Kofflard, Tobias Bruning, Henriett...

The aim of our study was to optimize CM delivery parameters, particularly the injection duration and iodine delivery rate (IDR), using systematic evaluation of the time attenuation curves (TAC) in low-kV thoraco-abdominal CTA acquired with dynamic CTA that covers the thoraco-abdominal aorta with high temporal resolution in a porcine model.Author: Michael M.

Background: High delivery rate is an important factor in optimizing contrast medium administration in coronary computed tomography angiography (CCTA). A personalized contrast volume calculation algorithm incorporating high iodine delivery rate (IDR) can reduce total iodine dose (TID) and produce optimal vessel contrast enhancement (VCE) in low tube voltage CCTA.Author: Sock Keow Tan, Kwan Hoong Ng, Chai Hong Yeong, Raja Rizal Azman Raja Aman, Fadhli Mohamed Sani, Yang...
