“…[13][14][15][16][17][18] When malignant and benign lesions were compared in regard to distribution and internal enhancement couples, we found that lesions with segmental distribution along with clustered-ring enhancement were significantly associated with malignancy (p < 0.05). This finding was also reported in a study by Asada et al 19 We also found a significant relationship between malignancy and diffuse distribution (p < 0.05); however, this may have been due to the low number of cases with diffuse distribution. The most frequent distribution types in our study were focal (31%) and linear (28.7%) distribution which were not associated with malignancy (p > 0.05).…”

“…Likewise, various studies have reported a lack of association between malignancy and homogeneous pattern and very low PPV values. 16,19,21,22,25 The most frequent dynamic curve type among malignant lesions was Type II curve (with a PPV of 34.1%) in the current study. In a study by Yang et al, the most frequent curve type among malignant lesions was also reported as Type II curve; however, their PPV of 74.1% was significantly higher than our result.…”

“…Furthermore, a couple of studies have reported that association with malignancy was the lowest with linear distribution. 19,20 The clustered-ring internal enhancement pattern has been reported by several studies to be a reliable predictor of malignancy. 18,[21][22][23] We also found a similar relationship (p < 0.05).…”

“…A branching line with the size of 1 cm or more was significantly more frequently associated with malignancy than a single line smaller than 1 cm [31]. Linear distribution with single line pattern smaller than 1 cm was recommended to be assigned to the BI-RADS 3 category [31,40]. Consistent with results from a previous study [23], 30.4% of non-calcified DCIS presenting as NME lesion showed the persistent enhancement.…”

Introduction: Challenges in differentiation between clinically noninflammatory granulomatous lobular mastitis (GLM) and noncalcified ductal carcinoma in situ (DCIS) remain. Objective: To identify the dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) characteristics contributing to their differential diagnosis. Methods: A total of 33 clinically noninflammatory GLM and 36 noncalcified DCIS were retrospectively analyzed in the study. Internal enhancement of a nonmass enhancement (NME) lesion was divided into clustered enhanced ring (absence/presence), and clustered enhanced ring (presence) was further classified as small and large ring based on the optimal cutoff value. The 5th Breast Imaging and Data System MRI descriptors were used for assessing the other DCE-MRI characteristics. Multivariate analysis including variables with significant differences in univariate analyses was conducted to identify the independent predictors. The discriminative abilities of different predictors and their combination were compared by area under the receiver-operating characteristic curves (AUCs). Results: An NME lesion was seen more commonly in clinically noninflammatory GLM than in noncalcified DCIS (p = 0.003). DCE-MRI characteristics with significant differences in univariate analyses included NME size, clustered enhanced ring (ab-sence/presence), ring size, initial increase and kinetic characteristics for the differentiation between these two entities presenting as NME lesion. Clustered enhanced ring (presence) was further classified as small (≤7 mm) or large ring (> 7 mm). Multivariate analysis revealed that internal enhancement and initial increase were identified as significant independent predictors, and the AUC of their combination achieved the highest value of 0.867 (95% CI, 0.748-0.943). Conclusions: An NME lesion with a large ring is more highly suggestive of clinically noninflammatory GLM.

“…Yang ve arkadaşları en fazla internal kontrastlanmanın halkasal patern olduğunu, PPD'sinin de %79.3 olduğunu rapor etmiştir (14). Genel olarak en fazla internal kontrastlanmanın halkasal patern olduğu ve malignite ile ilişkili olduğu ifade edilmiştir (6,15,(18)(19)(20). Kümelenmiş noktasal ve heterojen kontrastlanmanın ise malignite ile orta düzeyde ilişkili olduğu, kümelenmiş noktasal paternin PPD'lerinin de bizim sonuçlarımıza benzer şekilde %20 ile %32.8 arasında değiştiği rapor edilmiştir (6,21,22).…”

ÖZET GİRİŞ ve AMAÇ: American College of Radiology'nin Meme Görüntüleme Raporlama ve Veri Sistemi (BI-RADS) rehberinin 5. baskısına göre bugüne kadar az sayıda çalışmada, kitlesel olmayan kontrast tutulumu (non mass enhancement=NME) lezyonlarının özellikleri araştırılmıştır ve bu alana ilişkin yapılacak yeni çalışmaların gerekliliğinden söz edilmiştir. Bu çalışmada meme Manyetik Rezonans Görüntüleme (MRG)'de saptanan NME lezyonlarının özelliklerinin araştırılması amaçlandı. YÖNTEM ve GEREÇLER: Çalışmada 2015 ve 2017 yılları arasında Ankara Onkoloji Eğitim ve Araştırma Hastanesi'nde çekilen tüm meme MRG tetkikleri retrospektif taranarak değerlendirildi. Bu süre zarfında 23 hastada saptanan NME lezyonu çalışma grubunu oluşturdu. NME lezyonlarının dağılımı, paterni, dinamik eğri tipleri, difüzyon kısıtlaması olup olmadığı, kistik yapı olup olmadığı, fizik muayenede palpabl kitlenin bulunup bulunmadığı ve biyopsi sonuçları değerlendirildi. BULGULAR: Hastaların yaş ortalaması 43.86±6.95 (34-62) yıl idi. Biyopsi sonuçlarına göre 12'si (%52.2) benign, 5'i (%21.7) malign idi. NME lezyonlarının dağılım paterni incelendiğinde 10'u (%43.5) çoklu bölgesel, 13'ü (%56.5) bölgesel nitelikte idi. Malign karakterli lezyonların tamamının bölgesel patern gösterdiği izlendi. Dinamik eğrilerden en fazla saptanan persistan patern olan tip 1 (13, %56.5) eğri idi. Daha sonra plato patern olan tip 2 (9, %39.1) eğri görüldü. Lezyonlardan 4 (%17.4) tanesi palpabl idi. TARTIŞMA ve SONUÇ: Çalışmada çoklu bölgesel dağılım, bölgesel dağılımdan daha sık izlendi. Malign lezyonlarda benignlere göre bölgesel dağılım paterni anlamlı olarak daha yüksek görüldü. NME lezyonları ve dağılım paternleri ile internal kontrastlanma paternleri hakkında ileri çalışmalar özellikle çok merkezli çalışmalar yapılmalıdır. Anahtar Sözcükler: Kitlesel Olmayan Kontrast Tutulumu, Meme, Manyetik Rezonans Görüntüleme, Meme Görüntüleme Raporlama ve Veri Sistemi ABSTRACT INTRODUCTION: According to the 5th edition of Breast Imaging Reporting and Data System (BI-RADS) lexicon of the American College of Radiology (ACR), the features of non-mass enhancement (NME) lesions have been investigated in a small number of studies and the need for new studies on this area has been mentioned. In this study, we aimed to investigate the features of NME lesions of breast detected in Magnetic Resonance Imaging (MRI). METHODS: All breast MRIs performed at the Ankara Oncology Training and Research Hospital between 2015 and 2017 were reviewed and evaluated retrospectively. During this period, 23 NME lesions were detected in the MRI and constituted the study group. Distribution and pattern of NME lesions, curve types, presence of diffusion restriction, and presence of cystic structure, presence of palpable mass on physical examination and biopsy results were evaluated. RESULTS: The mean age of the patients was 43. 86 ± 6.95 (34-62) years. According to the biopsy results, 12 lesions (52.2%) were benign and 5 (21.7%) were malignant. When the distribution pattern of NME lesions was examined, 10 ...
