Iodinated contrast medium: Is there a re(n)al problem? A clinical ...
2020年11月10日 · As we were taught, for decades, that iodinated contrast-induced acute kidney injury should be dreaded, considerable efforts were made to find out effective measures in mitigating the renal risk of iodinated contrast media. Imaging procedures were frequently either downgraded (unenhanced imaging) or deferred as clinicians felt that the renal risk pertaining …
COVID-19: What Iodine Maps From Perfusion CT can reveal—A …
2020年10月21日 · Background Subtraction CT angiography (sCTA) is a technique used to evaluate pulmonary perfusion based on iodine distribution maps. The aim of this study is to assess lung perfusion changes with sCTA seen in patients with COVID-19 pneumonia and correlate them with clinical outcomes. Material and methods A prospective cohort study was …
Influence of contrast media on renal function and outcomes in …
2019年7月9日 · Background Recent studies have suggested a low potential risk for contrast medium-induced kidney injury in patients with relatively normal renal function. However, whether contrast media cause additional deterioration of renal function in patients with acute kidney injury (AKI), including those with sepsis-associated AKI, remains unclear. This study aimed to …
The aftermath of acute kidney injury: a narrative review of long …
2019年1月24日 · Acute kidney injury (AKI) is a frequent complication of hospitalization and is associated with an increased risk of chronic kidney disease (CKD), end-stage renal disease (ESRD), and mortality. While AKI is a known risk factor for short-term adverse outcomes, more recent data suggest that the risk of mortality and renal dysfunction extends far beyond hospital …
Incidence, risk factors and prediction of post-operative acute …
2013年10月4日 · Moreover, regarding risk associated with iodine contrast in our series, the benefit of contrast-enhanced computer tomography or angiography pre-operatively should be balanced with the risk to renal function. Finally, we identified multiple surgery as another risk factor for post-operative worsening of renal function.
Chest dual-energy CT to assess the effects of steroids on lung …
2022年10月25日 · Contrast-enhanced DECT is a powerful lung imaging method based on two concurrent X-ray energy spectra. Taking advantage of the different attenuation profiles of different substances, including iodine contrast, DECT can simultaneously characterize regional distribution of gas and blood volume in the lung parenchyma [ 16 , 17 ].
Risk of contrast induced nephropathy in the critically ill: a ...
2012年4月25日 · Introduction Computerized tomography is frequently employed in the critically ill, often using intravenous radiocontrast material. Many of these patients have clinical features that are considered risk factors for contrast induced nephropathy, but are simultaneously at risk for renal injury from other factors related to their acute illnesses. The attributable risk for renal …
Left ventricular wall findings in non-electrocardiography-gated ...
2019年11月14日 · Contrast medium (2 mL/kg [maximum 100 mL] of iopamidol [370 mg iodine/mL]) was intravenously injected from the peripheral vein of the left or right arm at a rate of 3.0–3.5 mL/s. Scans were performed at 30 s and 90 s after contrast injection. Classification of left ventricular wall findings on non-ECG-gated CE-CT
Contrast-induced acute kidney injury and renal support for acute …
2013年2月4日 · Acute kidney injury (AKI) is a common and serious problem affecting millions and causing death and disability for many. In 2012, Kidney Disease: Improving Global Outcomes completed the first ever international multidisciplinary clinical practice guideline for AKI. The guideline is based on evidence review and appraisal, and covers AKI definition, risk …
A universal predictive and mechanistic urinary peptide signature in ...
2022年11月7日 · During the postoperative period, patients included in the validation cohort received iodine contrast agents less frequently (p = 0.001) and had a shorter length of stay within the ICU (p < 0.0001). However, this did not lead to significant differences in AKI incidence between the derivation and validation cohort (~ 23%, KDIGO stage 1–3).
