| 1 | Correlation analysis of dual-energy CT iodine maps with quantitative pulmonary perfusion MRI显示文摘AIM:To correlate dual-energy computed tomography(DECT) pulmonary angiography derived iodine maps with parameter maps of quantitative pulmonary perfusion magnetic resonance imaging(MRI).METHODS:Eighteen patients with pulmonary perfusion defects detected on DECT derived iodine maps were included in this prospective study and additionally underwent time-resolved contrast-enhanced pulmonary MRI [dynamic contrast enhanced(DCE)-MRI].DCE-MRI data were quantitatively analyzed using a pixel-by-pixel deconvolution analysis calculating regional pulmonary blood flow(PBF),pulmonary blood volume(PBV) and mean transit time(MTT) in visually normal lung parenchyma and perfusion defects.Perfusion parameterswere correlated to mean attenuation values of normal lung and perfusion defects on DECT iodine maps.Two readers rated the concordance of perfusion defects in a visual analysis using a 5-point Likert-scale(1 = no correlation,5 = excellent correlation).RESULTS:In visually normal pulmonary tissue mean DECT and MRI values were:22.6 ± 8.3 Hounsfield units(HU);PBF:58.8 ± 36.0 mL/100 mL per minute;PBV:16.6 ± 8.5 mL;MTT:17.1 ± 10.3 s.In areas with restricted perfusion mean DECT and MRI values were:4.0 ± 3.9 HU;PBF:10.3 ± 5.5 mL/100 mL per minute,PBV:5 ± 4 mL,MTT:21.6 ± 14.0 s.The differences between visually normal parenchyma and areas of restricted perfusion were statistically significant for PBF,PBV and DECT(P < 0.0001).No linear correlation was found between MRI perfusion parameters and attenuation values of DECT iodine maps(PBF:r = 0.35,P = 0.15;PBV:r = 0.34,P = 0.16;MTT:r = 0.41,P = 0.08).Visual analysis revealed a moderate correlation between perfusion defects on DECT iodine maps and the parameter maps of DCE-MRI(mean score 3.6,k 0.45).CONCLUSION:There is a moderate visual but not statistically significant correlation between DECT iodine maps and perfusion parameter maps of DCE-MRI. | Jan Hansmann Paul Apfaltrer Frank G Zoellner Thomas Henzler Mathias Meyer Gerald Weisser Stefan O Schoenberg Ulrike I Attenberger | 2013 | World Journal of Radiology2013，5，5： | 6 |
| 2 | 副睾低级别子宫内膜间质肉瘤:1例报道并分子证实JAZF1/SUZ12易位显示文摘发生在睾丸及其附件起源于苗勒管样浆液型或黏液型的肿瘤极其罕见,近年来也被逐渐认识。伴或不伴卵巢样间质的囊腺瘤、交界性肿瘤或囊腺癌是主要的类型。尽管有少数子宫内膜样腺癌的报道,但据作者所知,目前文献仍没有子宫内膜间质肿瘤的报道。作者报道1例发生在59岁男性左侧阴囊内直径2 cm的肿块,超声检测该肿块位于附睾尾,血供丰富。该患者平素体健,无重大疾病史,无内分泌疾病或外用激素治疗史。睾丸肿瘤标志物指标(β-HCG,AFP)正常。 | Agaimy A Moskalev E A Weisser W 赵芳 魏建国 | 2018 | 临床与实验病理学杂志2018，34，9： | 4 |
