Correlation of Clinical Risk Factors with Diffusion-Weighted Magnetic Resonance Images in Prostate Cancer Patients Treated with Definitive Radiotherapy
Erbay, Gurcan; Onal, Cem; Guler, Ozan C.; Karadeli, Elif; Koc, Zafer (2015)This study is aimed to correlate apparent diffusion coefficient (ADC) values and clinical T-stage, serum PSA, pathology Gleason scores. We also further analyzed whether ADC values could be used to appropriately define the ... -
Diffusion-Weighted MRI and Optimal b-value For Characterization of Liver Lesions
Kaya, Bilal; Koc, Zafer (2014)Background: Diffusion-weighted imaging (DWI) is commonly used to distinguish between benign and malignant liver lesions. However, different b-values are recommended. Purpose: To determine the most suitable b-value in ... -
Effect of Hereditary Hemochromatosis Gene H63D and C282Y Mutations on Iron Overload in Sickle Cell Disease Patients
Terzi, Yunus Kasim; Balci, Tugce Bulakbasi; Boga, Can; Koc, Zafer; Celik, Zerrin Yilmaz; Ozdogu, Hakan; Karakus, Sema; Sahin, Feride Iffet (2016)Objective: Hemochromatosis is an autosomal recessive disease that is one of the most important reasons for iron overload. Sickle cell disease is a hemoglobinopathy that occurs as a result of a homozygous mutation in the ... -

Internal Comparison Standard for Abdominal Diffusion-Weighted Imaging
Koc, Zafer; Erbay, Gurcan; Karadeli, Elif (2017)Background: Standards for abdominal diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC) measurements, and analysis are required for reproducibility. Purpose: To identify optimal internal comparison ... -
Optimal b Value in Diffusion-Weighted Imaging for Differentiation of Abdominal Lesions
Koc, Zafer; Erbay, Gurcan (2014)Purpose: To explore the optimal b value in diffusion-weighted imaging (DWI) for differentiation of benign and malignant abdominal lesions. Materials and Methods: A total of 108 consecutive patients (age 60 +/- 12.5 ... -
Predicting Tumor Recurrence in Patients with Cervical Carcinoma Treated with Definitive Chemoradiotherapy: Value Of Quantitative Histogram Analysis On Diffusion-Weighted MR Images
Erbay, Gurcan; Onal, Cem; Karadeli, Elif; Guler, Ozan C.; Arica, Sami; Koc, Zafer (2017)Background: Further research is required for evaluating the use of ADC histogram analysis in more advanced stages of cervical cancer treated with definitive chemoradiotherapy (CRT). Purpose: To investigate the utility ... -
Prognostic values of ADC(mean) and SUVmax of the primary tumour in cervical cancer patients treated with definitive chemoradiotherapy
Yildirim, Berna Akkus; Onal, Cem; Erbay, Gurcan; Guler, Ozan Cem; Karadeli, Elif; Reyhan, Mehmet; Koc, Zafer (2019)We analysed the correlation of F-18-fluorodeoxyglucose uptake into primary tumours using the maximum standardised uptake value (SUVmax) and the mean apparent diffusion coefficient (ADC(mean)) values in magnetic resonance ... -
Radiologic findings mimicking acute abdomen in a patient with colorectal cancer: are these side effects of FOLFIRI therapy?
Karadeli, Elif; Erbay, Gurcan; Koc, Zafer (2016)Bowel perforation is an emergency problem, it presents as an acute abdomen. Computurize tomography (CT) is important imaging modality used to evaluate patients with acute abdomen. CT shows anatomical detail and intestinal ... -
A rarely seen diffuse parenchymal lung disease: diffuse pulmonary meningotheliomatosis
Sen, Nazan; Canpolat, Emine Tuba; Koc, Zafer (2015)Pulmonary meningothelial- like nodules (MLNs) are usually detected incidentally during pathologic evaluation of resected pulmonary parenchymal specimens and autopsies. These nodules are generally asymptomatic and most often ... -
