CT compared to MRI for functional evaluation of the right ventricle: a systematic review and meta-analysisRight ventricular functionComputed tomographyMagnetic resonance imagingMeta-analysisObjective Right ventricular function (RVF) is a strong predictor of adverse cardiac events; however, the reference ...
In our retrospective study, CT had a sensitivity of 0.875 [0.719–0.950, 95% CI] and a specificity of 1.000 [0.930–1.000, 95% CI] in detecting all cervical spine injuries compared to MRI. However, all patients with missed injuries had intramedullary T2 hyper intensity consistent with ...
MRI examination,SE T1,T2 weighted images was chose.Post contrast MRI examination was performed using the same SE T1 sequence as the per contrast MRI imaging .CT was performed with plain scans and contrast-enhanced scans.Results Compared with CT, MRI can revel early abnormality of tuberculosis ...
The advent of whole-body MRI (WB-MRI) has introduced tumor imaging with a systemic approach compared to established sequential, multi-modal diagnostic algo... GP Schmidt,MF Reiser,A Baur-Melnyk - 《European Journal of Radiology》 被引量: 264发表: 2009年 Whole-body MRI for the staging and ...
影像检查已成为疾病,包括各种疑难病诊断、治疗和随访的重要手段。疑难病容易被误诊和漏诊,往往需要反复进行多次影像检查才能准确诊断及治疗,相比其他疾病需要耗费更多的时间、经济成本和医疗资源,临床迫切希望能有一步到位诊断疑难病的解决方案。 在这样的背景下,光谱...
但在急性出血,MRI却一直有心无力。由于不能可靠的识别脑出血,卒中急性期始终由CT一统江湖。2003版AHA急性缺血性卒中指南[1],隆重推荐CT,只给MRI留了个悬念。 没想到仅仅过了一年,核磁出了大招,动员美国的UCLA和德国的海德堡大学牵头,分别在JAMA和Stroke上各出一记重拳[2,3],一举扭转颓势,自此各大指南纷纷见风...
Similar root images and almost the same root length were obtained for roots grown in the small pot, while more root details showed up in the CT images compared to MRI. For the medium sized pot, MRI showed more roots and higher root lengths whereas at some spots thin roots were only ...
The likelihood of allograft failure was about 100-fold higher in recipients with mutant NOD2 alleles compared with recipients with wild-type NOD2 loci. Rejection in NOD2 mutant recipients was characterised by decreased expression of certain Paneth cell and enterocyte AMPs, prior to the onset of ...

Within 30 ± 7 d after the ablation procedure, 118/139 patients were monitored to assess the tumor response to treatment. Before ablation, contrast enhancement within tumor was observed in 129/139 (92.8%) patients with CEUS and 133/139 (95.7%) patients with CECT/CEMRI. Compared with CECT/...
