MATERIALS AND METHODS: 10 subjects underwent NC-MRV and CE-MRV at 1.5 T, with comparison to US. Two radiologists evaluated MRI for image quality (IQ) and venous caliber. RESULTS AND CONCLUSIONS: NC-MRV is feasible, with inferior IQ but comparable venous caliber measurements CE-MRV (mean 7.9±4.58 mm vs. 7.83±4.62, p=0.13). Slightly larger upper limb caliber measurements were derived for NC-MRV and CE-MRV compared to US (NC-MRV 5.2±1.8 mm, CE-MRV 4.9±1.6 mm, US 4.5±1.8 mm, both p<0.001). | URI: | https://ahro.austin.org.au/austinjspui/handle/1/16678 | DOI: | 10.1016/j.clinimag.2017.05.020 | ORCID: | 0000-0002-0955-5446 | Journal: | Clinical Imaging | PubMed URL: | https://pubmed.ncbi.nlm.nih.gov/28601736 | Type: | Journal Article | Subjects: | Magnetic resonance venography Non-contrast Renal failure Ultrasound Venous mapping |
