Polysaccharide super paramagnetic ferric oxide injection is an iron supplement developed for patients with iron deficiency anemia. Due to its characteristics, it has the potential to be a contrast agent. The DJTCSCYHT-I-04 study is a single-center, multiple-strength and single-dose phase I clinical study on cardiovascular MRI in patients with chronic kidney disease, aiming to investigate the effects and safety of multi-strength, single-dose at different time points, and to provide reference for clinical diagnosis and MRI enhancement.

RECRUITINGSignal-to-Noise Ratio (SNR)
On the basis of vascular segments, the signal-to-noise ratio at different doses and time points was calculated by magnetic resonance imaging.
Time frame: Before administration, 5minutes, 24 hours, 48 hours after administration
Contrast to noise ratio (CNR)
On the basis of vascular segments, the Contrast to noise ratio at different doses and time points was calculated by magnetic resonance imaging.
Time frame: Before administration, 5minutes, 24 hours, 48 hours after administration
Image quality score before administration
On the basis of vascular segments, the image quality of different doses at different time points was evaluated by magnetic resonance imaging. 4 points: the blood vessel edge is clear and sharp, without image artifacts, which can support the judgment of high confidence; 3 points: The overall portrayal effect of blood vessels was satisfactory, the anatomical structure of blood vessels was clear enough to meet the requirements of disease diagnosis, and there were mild image artifacts; 2 points: Blood vessels were visible, but only the local structure size or blood vessel patency could be judged, with moderate image artifacts; 1 point: poor image quality, serious image artifacts, unable to distinguish blood vessels and other tissues, unable to evaluate.
Time frame: Before administration
Image quality score at 5 minutes
On the basis of vascular segments, the image quality of different doses at different time points was evaluated by magnetic resonance imaging. 4 points: the blood vessel edge is clear and sharp, without image artifacts, which can support the judgment of high confidence; 3 points: The overall portrayal effect of blood vessels was satisfactory, the anatomical structure of blood vessels was clear enough to meet the requirements of disease diagnosis, and there were mild image artifacts; 2 points: Blood vessels were visible, but only the local structure size or blood vessel patency could be judged, with moderate image artifacts; 1 point: poor image quality, serious image artifacts, unable to distinguish blood vessels and other tissues, unable to evaluate.
Time frame: 5 minutes after administration
Image quality score at 24 hours
On the basis of vascular segments, the image quality of different doses at different time points was evaluated by magnetic resonance imaging. 4 points: the blood vessel edge is clear and sharp, without image artifacts, which can support the judgment of high confidence; 3 points: The overall portrayal effect of blood vessels was satisfactory, the anatomical structure of blood vessels was clear enough to meet the requirements of disease diagnosis, and there were mild image artifacts; 2 points: Blood vessels were visible, but only the local structure size or blood vessel patency could be judged, with moderate image artifacts; 1 point: poor image quality, serious image artifacts, unable to distinguish blood vessels and other tissues, unable to evaluate.
Time frame: 24 hours after administration
Image quality score at 48 hours
On the basis of vascular segments, the image quality of different doses at different time points was evaluated by magnetic resonance imaging. 4 points: the blood vessel edge is clear and sharp, without image artifacts, which can support the judgment of high confidence; 3 points: The overall portrayal effect of blood vessels was satisfactory, the anatomical structure of blood vessels was clear enough to meet the requirements of disease diagnosis, and there were mild image artifacts; 2 points: Blood vessels were visible, but only the local structure size or blood vessel patency could be judged, with moderate image artifacts; 1 point: poor image quality, serious image artifacts, unable to distinguish blood vessels and other tissues, unable to evaluate.
