Coronary stent evaluation with coronary computed tomographic angiography: Comparison between low-osmolar, high-iodine concentration iomeprol-400 and iso-osmolar, lower-iodine concentration iodixanol-320

Did low tube voltage CT combined with low contrast media burden protocols accomplish the goal of “double low” for patients? An overview of applications in vessels and abdominal parenchymal organs over the past 5 years

“…Protocols at 100 kVp tube voltages have been shown to provide similar image quality as the formerly used 120 kVp techniques at a significantly lower radiation dose in pCTA and cCTA . A number of studies have been performed to compare the protocols of 80–120 kVp or 100 kVp to explore additional radiation dose reductions.…”

“…In cardiac CT, prospective electrocardiograph gating reduces the radiation dose to quantum leap because the X‐ray tube is only turned on at a predefined time point in the cardiac cycle. This technique is not mentioned in Table but was widely applied in the current studies …”

In vitro and in vivo evaluation of effect of excipients in local delivery of paclitaxel using microporous infusion balloon catheters

“…20 In our study, iodixanol was used since it causes less renal toxicity than several other intravascular contrast agents that are currently available. 11 However, due to the poor solubility of PAT in iodixanol, the formulation did not work either for infusing out a clinically relevant dose of PAT or for assisting in drug uptake into the tissue. The strong adhesion of PAT toward PTFE material has been previously demonstrated.…”

Cardiac CT Angiography Manual

“…9.14) [39]. Studies have also shown that newer detector technology may improve stent evaluation, including using novel integrated electronics and also using the gem stone detector [40][41][42] Investigators have also evaluated the effect of low-osmolar, high iodine concentration contrast versus iso-osmolar, lower iodine concentration contrast on stent imaging with CCTA and found that the latter provides better image quality [43]. Additionally, the evaluation of stents using a combination of myocardial computed tomography perfusion (MCTP) along with traditional CCTA is being investigated.…”
