“…18 carotid arteries were evaluated in the 9 patients in group A (Gadobutrol-enhanced MRA) and 42 carotid arteries were evaluated in the 21 patients in group B (Gadoteridol-enhanced MRA) ( Table 1). The average contrast agent volume administered was 7.3 ± 1.2 ml [6][7][8][9][10] in group A and 14 ± 1.9 ml [11][12][13][14][15][16][17][18] (Fig. 1).…”

“…Moreover, it is the sole agent approved for high-dose administration (0.3 mmol/kg) due in part to its high stability and thus lower potential for toxicity from long-term heavy metal deposition [11,12]. Despite the inherent safety of Gadoteridol, only a few studies have evaluated the performance of this contrast medium in MRA [13][14][15][16].…”

Background: To compare image quality and diagnostic performance of Gadoteridol-enhanced MR angiography (MRA) with Gadobutrol-enhanced MRA in the evaluation of carotid artery stenosis. Methods: MRA was performed in 30 patients with carotid stenosis diagnosed at DUS. Patients were randomly assigned to group A (Gadobutrol-enhanced MRA) or group B (Gadoteridol-enhanced MRA). All examinations were performed with a 3T MR system. Image quality was assessed qualitatively by a 3-grade scale and quantitatively with SNR measurements. Diagnostic performance in the assessment of stenosis, plaque length and morphology was evaluated in the two MRA groups by accuracy calculation and RoC curves analysis using CTA as reference standard. Statistically significant differences in SNR and quality scale were evaluated by the Independent-Samples T Test and Mann-Whitney test, while the Z-statistics was used to compare diagnostic accuracy in the two groups. Results: Image quality was graded adequate to excellent for both GBCAs, without significant differences (p = 0.165). SNR values were not significantly different in group B (Gadoteridol-enhanced MRA) as compared to group A (Gadobutrol-enhanced MRA) (89.32 ± 70.4 vs 81.09 ± 28.38; p = 0.635). Diagnostic accuracy was 94 % for the evaluation of stenosis degree and 94 % for the identification of ulcerated plaques in group A, while it was 93 % for the evaluation of stenosis degree and 76 % for the identification of ulcerated plaques in group B, without statistically significant differences (p = 0.936). Conclusion: No significant difference in terms of image quality and diagnostic accuracy was observed between Gadoteridol-enhanced MRA and Gadobutrol-enhanced MRA in patients undergoing evaluation of carotid stenosis.

“…Contrast-enhanced MRA, which does not involve radiation, has been used for evaluating dysfunctional AVFs, with impressive results. 16,19 Unfortunately, concerns about a possible relationship between gadolinium-based contrast agents and nephrogenic systemic fibrosis (NSF) have brought into question the use of these agents for MRA. 20,21 Although this relationship has not been conclusively proven, an association has been seen in several studies.…”

Non-contrast-enhanced MR angiography for detecting arteriovenous fistula dysfunction in haemodialysis patients

“…Magnetic resonance angiography enables visualization of the access without the use of ionizing radiation or intravenous contrast material. The performance of magnetic resonance angiography in the evaluation of hemodialysis access also has been compared favorably with that of DSA [12, 13]. However, a major problem of magnetic resonance angiography has been the inability to visualize the graft in combination with its runoff vessels to the superior caval vein.…”

Aims: To introduce our preliminary experience in using multislice computed tomographic (CT) angiography (MSCTA) to assess stenoses of the hemodialysis vascular access and to guide revising operation or percutaneous transluminal angioplasty (PTA). Methods: Contrast-enhanced 16-slice spiral CT was used to examine 22 hemodialysis patients with various dysfunctions of their vascular access. The transverse source images were reformatted as maximum intensity projection, volume-rendering, and multiple/curved planar reconstruction images. Results: The whole spectrum of arteriovenous fistulas (AVF) with the feeding artery, anastomoses, and outflow tract up to the superior caval vein was clearly displayed in all patients. According to the results of MSCTA, AVF-revising surgery was done in 11 patients, and PTA under the guide of digital subtraction angiography (DSA) was done in 5 patients. The results of MSCTA coincide with the findings of surgery or DSA in these 16 patients. Conclusions: In our opinion, MSCTA is a good noninvasive diagnostic technique to detect various hemodialysis vascular access abnormalities. It is more economical than DSA in the present medical settings and could replace DSA in the imaging of hemodialysis vascular access and provide important information for further AVF-revising surgery or PTA.
