采用双能量造影剂增强数字减影乳房x线摄影技术，对26名乳房x线摄影或临床表现证实活检的患者进行了乳腺癌诊断。该技术包括高能和低能数字乳房x线摄影后，碘造影剂的管理。然后对这些图像的对数变换进行加权减法，以获得优先显示碘的图像。在26名受试者中，13名患有侵袭性癌症。其中11个肿瘤强化，1个中度强化，1个弱强化。1例导管原位癌患者导管微弱强化。在其他12例患者中，2例良性组织弥漫性增强，2例轻度局灶性增强。结果表明，该技术是可行的，值得进一步研究。(c) rsna, 2003。
A technique for demonstrating breast cancers, dual-energy contrast agent-enhanced digital subtraction mammography, was performed in 26 subjects with mammographic or clinical findings that warranted biopsy. The technique consists of high-energy and low-energy digital mammography after administration of iodinated contrast agent. Weighted subtraction of the logarithmic transform of these images is then performed to obtain an image that preferentially shows iodine. Of the 26 subjects, 13 had invasive cancers. Eleven of these tumors enhanced strongly, one enhanced moderately, and one enhanced weakly. The duct in one patient with ductal carcinoma in situ was weakly enhancing. In the other 12 patients, benign tissue enhanced diffusely in two and weakly focally in two. These results indicate that the technique is feasible and worthy of further study. (C) RSNA, 2003.
