Brief Summary:
It is well known that X-ray contrast media can affect kidney function in some patients, especially when administered intra-arterially, and patients who already suffer from reduced kidney function and diabetes mellitus may be at increased risk. It is widely accepted to use low-osmolar or iso-osmolar contrast media, especially in patients at risk for contrast media-induced nephropathy. However, little is known about the intravenous use of X-ray contrast media in risk patients, such as contrast-enhanced CT examinations. The main purpose of this study is to evaluate and compare the effects on kidney function of two contrast media, the iso-osmolar iodixanol and the low-osmolar iopamidol in patients at risk of kidney damage associated with the injection of contrast media. Due to the iso-osmolar feature, it is expected less influence on renal function following administration of iodixanol. A standard hydration procedure, based on available guidelines will be given to all patients to prevent negative effects on the kidneys. Serum creatinine (SCr ) concentrations will be measured before and up to 7 days after contrast media administration to evaluate the effects on renal function.

Arm Intervention/treatment
Active Comparator: Iodixanol 320-Arm 1
Iodixanol 320 mg I/mL
Drug: Iodixanol 320-Arm 1
Other Name: Visipaque

Active Comparator: Iopamidol 300-Arm 2
Iopamidol 300 mg I/mL

Primary Outcome Measures :
  1. Assessment of the Incidence Rate of Contrast Medium-Induced Nephropathy (CIN) Between Iodixanol and Iopamidol in Patients With Impaired Renal Function. [ Time Frame: From baseline up to 3 days post contrast administration. ]

    The primary endpoint was the incidence rate of CIN, defined as an intra-individual increase in serum creatinine (SCr) of greater than or equal to 44.2 µmol/L (greater than or equal to 0.5 mg/dL).

    Subjects with a pre-contrast (baseline) serum creatinine value greater than or equal to 1.5 mg/dL for males and greater than or equal to 1.3 mg/dL for females or eGFR of less than or equal to 50 mL/min/1.73m squared, and a post-contrast serum creatinine value available on days 2 or 3, administered greater than or equal to100 mL or greater than or equal to 1.5 mL/kg bodyweight IMP, without presence of any major protocol violations, and without evidence of other causes inducing acute renal dysfunction.

Secondary Outcome Measures :
  1. Assessment of Overall Image Quality Between Iodixanol and Iopamidol in Patients Undergoing Contrast-enhanced Multi-detector-row Helical Computed Tomography (MDCT) Examination. [ Time Frame: Within 2, 3 and 7 days post contrast administration. ]
    Overall Image Quality rated as "Excellent, Good, Sufficient or Insufficient Poor" by radiologists blinded to the contrast administration.
