Contrast enhanced mammography (CEM), a relatively new and promising modality, combines mammography (MMG) with an iodinated contrast material to illuminate neovascularity within the breast; analogous to magnetic resonance imaging (MRI). CEM improves the overall sensitivity of MMG; reduces the need for unnecessary biopsies and follow-up imaging and can be considered a reasonable substitute for MRI. In Pakistan, CEM was recently introduced and to assess its usability a study was conducted on five patients before making it available as a regular investigation.
Four out of the five patients had a clinical suspicion of malignancy with two patients having heterogeneously dense breasts and two with dense breasts. All enhancing lesions were concordant on biopsy and had similar corresponding findings on additional imaging such as ultrasound (US) and/or MRI. CEM in all four cases of biopsy proven malignancy facilitated surgical planning. The fifth patient underwent CEM for screening and was found to have no enhancing lesion.
In low-middle-income countries (LMICs) where breast MRI is not readily available and expensive for the populace, CEM can be a reliable alternative. The initial experience with CEM at our hospital shows better visualization of malignant lesions in dense and heterogeneously dense breasts with an easy-to-perform technique and a shorter imaging time while facilitating surgical decision-making in terms of breast conservation.
对比增强乳腺造影(CEM)是一种相对较新且有前景的检查方式,它将乳腺X线摄影(MMG)与碘化造影剂相结合,以显示乳腺内的新生血管,类似于磁共振成像(MRI)。CEM提高了MMG的整体敏感性,减少了不必要的活检和后续成像的需求,可被视为MRI的合理替代方法。在巴基斯坦,CEM最近才被引入,为评估其可用性,在将其作为常规检查项目之前,对5名患者进行了一项研究。
5名患者中有4名临床怀疑为恶性肿瘤,其中2名患者乳房呈不均匀致密型,2名患者乳房呈致密型。所有强化病变在活检时均得到证实,在超声(US)和/或MRI等其他影像学检查中也有类似的相应表现。在所有4例活检证实为恶性肿瘤的病例中,CEM有助于手术规划。第5名患者接受CEM筛查,未发现强化病变。
在中低收入国家(LMICs),乳腺MRI不易获得且对民众来说费用高昂,CEM可以是一种可靠的替代方法。我们医院使用CEM的初步经验表明,该技术能更好地显示致密型和不均匀致密型乳房中的恶性病变,操作简便,成像时间短,同时有助于在保乳方面做出手术决策。
