A newly made algorithm was used for CT. Data of 900 projections with interval of 0.2 degrees were used. Ductus lactiferi, microcalci-fication in a 3D form have been clearly visible. The spatial resolution available was approximately 30μm.展开更多
目的探讨全数字化乳腺X线摄影(full-field digital mammography,FFDM)对乳腺导管原位癌的诊断价值。方法回顾性分析52例经穿刺或手术病理证实的乳腺导管原位癌的X线摄影表现。结果以恶性钙化为主要征象32例,钙化表现为微细、多形性,呈...目的探讨全数字化乳腺X线摄影(full-field digital mammography,FFDM)对乳腺导管原位癌的诊断价值。方法回顾性分析52例经穿刺或手术病理证实的乳腺导管原位癌的X线摄影表现。结果以恶性钙化为主要征象32例,钙化表现为微细、多形性,呈簇状、群集或段性分布,其中单纯钙化24例,钙化合并局灶性致密8例;表现为肿块8例,其中3例肿块边缘见毛刺;单纯局灶性致密3例;结构扭曲2例;导管造影显示导管内占位性病变3例;X线无异常发现4例。结论 FFDM可以清晰显示微小钙化、小结节、局灶致密及结构扭曲等征象,尤其对微小钙化敏感,对乳腺导管原位癌的诊断具有重要价值。展开更多

目的探讨乳腺钼靶摄片对乳腺导管内癌(ductal carcinoma in situ,DCIS)的诊断价值。方法按照病人主诉分组,回顾性分析20例患者、21个经病理证实为DCIS病灶的钼靶影像特征,与病理结果对照研究。结果以触诊乳腺肿物为主诉的9例患者10个病...目的探讨乳腺钼靶摄片对乳腺导管内癌(ductal carcinoma in situ,DCIS)的诊断价值。方法按照病人主诉分组,回顾性分析20例患者、21个经病理证实为DCIS病灶的钼靶影像特征,与病理结果对照研究。结果以触诊乳腺肿物为主诉的9例患者10个病灶中,表现为结节并微小钙化者6例,乳头血性溢液者1例,片状增高密度影2例,另1例患者影像表现阴性,上述后3例病灶行细针穿刺细胞学检查确诊;以腺体增厚为主诉的5例患者中,钼靶表现为腺体结构紊乱,密度不均,其中2例伴微小钙化及乳头溢液,单纯性微小钙化3例;以单纯性乳头溢液为主诉者2例,均伴微小钙化,导管造影示导管局部显影中断或间断显影;以乳腺癌术后复查发现另一侧乳腺单纯性微小钙化灶者2例;1位患者因乳腺脂肪瘤而漏诊。结论钼靶影像学能为DCIS的诊断提供重要依据,尤其对临床检查阴性的患者,乳腺钼靶摄片辅以导管造影及细针穿刺细胞学检查是诊断早期乳腺癌不可或缺的手段。展开更多
