Publication Metadata only Papillary Lesions of the Breast: Addition of DWI and TIRM Sequences to Routine Breast MRI Could Help in Differentiation Benign from Malignant(2022-01-01T00:00:00Z) GÜLTEKİN, MEHMET ALİ; ÇELİK YABUL, FATMA; OTÇU TEMUR, HAFİZE; SARI, LÜTFULLAH; YILMAZ, TEMEL FATİH; TOPRAK, HÜSEYİN; YILDIZ, ŞEYMA; GÜLTEKİN, MEHMET ALİ; ÇELİK YABUL, FATMA; OTÇU TEMUR, HAFİZE; SARI, LÜTFULLAH; YILMAZ, TEMEL FATİH; TOPRAK, HÜSEYİN; YILDIZ, ŞEYMAAim: We aimed to investigate the magnetic resonance imaging (MRI) features of benign, atypical, or malignant papillary breast lesions and to assess the additional value of diffusion-weighted imaging (DWI) and turbo inversion recovery magnitude (TIRM) sequences to routine breast MRI. Background: Differentiation between benign and malignant papillary breast lesions is essential for patient management. However, morphologic features and enhancement patterns of malignant papillary lesions may overlap with those of benign papilloma. Methods: Seventy-two papillary breast lesions (50 benign, 22 atypical or malignant) were included in the current study, retrospectively. We divided the patients into two groups: benign papillary breast lesions and atypical or malignant papillary breast lesions. Morphologic, dynamic, turbo inversion recovery magnitude (TIRM) values and diffusion features of the papillary lesions were compared between two groups. Results: Benign papillary lesions were smaller in size (p=0.006 and p=0.005, for radiologists 1 and 2 respectively), closer to the areola (p=0.045 and 0.049 for radiologist 1 and 2 respectively), and had higher ADC values (p=0.001 for two radiologists) than the atypical or malignant group. ROC curves showed diagnostic accuracy for ADC (AUC=0.770 and 0.762, p & lt; 0.0001 for two radiologists), and showed a cut-off value of <= 957 x 10-6 mm(2/s) (radiologist 1) and <= 910 x 10-6 mm(2/s) (radiologist 2). Conclusion: MRI is a useful method for differentiation between benign and malignant papillary breast lesions. Centrally located, lesser in size, and higher ADC values should be considered benign, whereas peripherally located, larger in size, and lower ADC values should be considered malignant.Publication Open Access Comparison of MRI Features of Invasive Pleomorphic and Classical Lobular Carcinoma: Differentiation Is Possible?(2022-01-01T00:00:00Z) YILMAZ, TEMEL FATİH; OTÇU TEMUR, HAFİZE; SARI, LÜTFULLAH; GÜCİN, ZÜHAL; GÜLTEKİN, MEHMET ALİ; ÇELİK YABUL, FATMA; TOPRAK, HÜSEYİN; YILDIZ, ŞEYMA; YILMAZ, TEMEL FATİH; OTÇU TEMUR, HAFİZE; SARI, LÜTFULLAH; GÜCİN, ZÜHAL; GÜLTEKİN, MEHMET ALİ; ÇELİK YABUL, FATMA; TOPRAK, HÜSEYİN; YILDIZ, ŞEYMATo evaluate breast MRI and DWI and demographic features of pleomorphic invasive lobular carcinoma (pILC) and classic invasive lobular carcinoma (cILC). Invasive lobular (ILC) is the second most common breast malignancy after invasive ductal carcinoma (IDC) and constitutes the 8-14% of all invasive breast cancers. ILC morphologically can be classified into the classic, alveolar, solid, tubulolobular, and pleomorphic subtypes according to WHO. This study was performed retrospectively. The MRI and demographic features of 18 patients with 23 pILC were compared with those 22 consecutive patients with 27 cILC. There was no significant difference in demographic features of patients, MR appearance, kinetics, and ADC values between two groups. pILC, an aggressive subtype of ILC, cannot be differentiated from cILC with breast MRI.Publication Metadata only Simultaneous mass-forming pseudoangiomatous stromal hyperplasia of the breast, axilla, and perineum.(2019-11-01T00:00:00Z) Kiran, T; Peker, A; Yilmaz, TF; Yildiz, S; TOPRAK, HÜSEYİN; YILMAZ, TEMEL FATİH; KIRAN, TUĞÇE; YILDIZ, ŞEYMAPublication Metadata only Gastrointestinal Sistem Perforasyonu Olan Olgularda Bilgisayarlı Tomografi İncelemesinde Aksiyal ve Koronal Reformat Görüntülerin Tanıya Katkısı(2013-11-10T00:00:00Z) YILDIZ, ŞEYMA; TOPRAK, HÜSEYİN; AHMAD, ISAM CHEİCK; YETİŞ, HÜSEYİN; KADIOĞLU, HÜSEYİN; KOCAKOÇ, ERCAN; YILDIZ, ŞEYMA; TOPRAK, HÜSEYİN; KOCAKOÇ, ERCANPublication Open Access Stab injury of the thoracic aorta: computed tomography findings.(2013-01-01) Yildiz, S; Toprak, HÜSEYİN; SERTER, ASLI; KOCAKOÇ, ERCAN; YILDIZ, ŞEYMA; TOPRAK, HÜSEYİNStab injury of the thoracic aorta is a rare condition with high mortality rate. Patients must be evaluated carefully, and the diagnosis usually should be confirmed by radiological modalities. In this case, we report a 37-year-old man presented with a penetrating stab injury to the upper back and the thoracic aorta, and the diagnostic role of computed tomography is discussed.Publication Metadata only Granülomatöz mastitde MR bulguları(2013-05-25) YILDIZ, ŞEYMA; YETİŞ, HÜSEYİN; TOPRAK, HÜSEYİN; ARALAŞMAK, AYŞE; KOCAKOÇ, ERCAN; YILDIZ, ŞEYMA; TOPRAK, HÜSEYİN; ARALAŞMAK, AYŞEPublication Metadata only Baş boyun kitlelerinde MR perfüzyon bulguları(2013-05-25) ARALAŞMAK, AYŞE; YETİŞ, HÜSEYİN; YILDIZ, ŞEYMA; MERİÇ HAFIZ, AYŞENUR; BÜYÜKPINARBAŞILI, NUR; TOPRAK, HÜSEYİN; ALKAN, ALPAY; ARALAŞMAK, AYŞE; YILDIZ, ŞEYMA; MERİÇ HAFIZ, AYŞENUR; BÜYÜKPINARBAŞILI, NUR; TOPRAK, HÜSEYİN; ALKAN, ALPAYPublication Metadata only Primary diffuse leptomeningeal gliomatosis(2016-01-01) Çetinkaya, EZRA; ARALAŞMAK, AYŞE; TOPRAK, HÜSEYİN; YILDIZ, ŞEYMA; YURTSEVER, İSMAİL; ALKAN, ALPAY; ÇETİNKAYA, EZRA; ARALAŞMAK, AYŞE; TOPRAK, HÜSEYİN; YILDIZ, ŞEYMA; YURTSEVER, İSMAİL; ALKAN, ALPAYPublication Open Access CT and MRI Findings of Hepatic Involvement in Rendu-Osler-Weber Disease.(2012-01-01) Bilgin, MEHMET; Yildiz, S; Toprak, HÜSEYİN; AHMAD, ISSAM CHEIKH; KOCAKOÇ, ERCAN; BİLGİN, MEHMET; YILDIZ, ŞEYMA; TOPRAK, HÜSEYİNRendu-Osler-Weber disease is a rare autosomal dominant disorder. Hepatic involvement manifests itself as vascular, parenchymal, and biliary lesions with characteristic telangiectasias and vascular shunts. In a 37-year-old female patient, dynamic contrastenhanced upper abdominal CT and MRI were performed. CT and MRI revealed dilated celiac trunk and hepatic artery. On early arterial phase, dilated hepatic veins showed significant enhancement. On arterial and portal venous phases, liver showed significantly heterogeneous contrast enhancement and showed homogenous enhancement in the hepatic parenchymal phase. On the magnetic resonance cholangiopancreatography, irregular biliary ducts with strictures and dilatation were seen.Publication Open Access Integration of ultrasound findings with Alvarado score in children suspected appendicitis(2014-01-01) TOPRAK, HÜSEYİN; KILINCASLAN, HUSEYIN; AHMAD, ISSAM CHEIKH; YILDIZ, ŞEYMA; BİLGİN, MEHMET; SHARIFOV, RASUL; ACAR, MURAT; TOPRAK, HÜSEYİN; YILDIZ, ŞEYMA; BİLGİN, MEHMET; SHARIFOV, RASUL
