Urography with iohexol. Comparison with metrizoate and iodamide

Area of Science:

• Radiology and Medical Imaging
• Pharmacology
• Clinical Trials

Background:

• Contrast media are essential for diagnostic imaging.
• Non-ionic and ionic contrast agents have different safety profiles.
• Iohexol, metrizoate, and iodamide are commonly used contrast agents.

Purpose of the Study:

• To compare the diagnostic properties and adverse reactions of iohexol with Na-Ca-Mg metrizoate and meglumine iodamide.
• To evaluate patient tolerance and subjective sensations associated with these contrast media.

Main Methods:

• Two separate clinical trials were conducted.
• Iohexol (non-ionic) was compared against Na-Ca-Mg metrizoate (ionic) and meglumine iodamide (ionic).
• Diagnostic efficacy, subjective sensations, and other adverse reactions were assessed.

Main Results:

• No significant difference in diagnostic properties was observed between the contrast media.
• Iohexol resulted in a significantly lower frequency of subjective sensations compared to metrizoate.
• Iohexol demonstrated significantly fewer adverse reactions than iodamide and a slight advantage over metrizoate.

Conclusions:

• Iohexol exhibits a favorable safety profile with reduced adverse reactions and improved patient tolerance compared to ionic contrast media like metrizoate and iodamide.
• Iohexol is a viable alternative for contrast-enhanced diagnostic imaging, offering comparable diagnostic efficacy with enhanced safety.
