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 ... -
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 ... -
Results of Surgical Treatment of Anterior Abdominal Wall Desmoid Tumours: 13 Cases Reviewed with Literature
Yabanoglu, H.; Karagulle, E.; Aytac, H. O.; Caliskan, K.; Canpolat, T.; Koc, Z.; Akdur, A. C.; Moray, G.; Haberal, M. (2014)Background : We retrospectively evaluated the results of surgical treatment for anterior abdominal wall desmoid tumours. Methods : Records for 13 patients operated on for desmoid tumours from 1997-2013 were searched for ... -
Thorax CT Dose Reduction Based on Patient Features: Effect of Patient Characteristics on Image Quality and Effective Dose
Koc, Gizem Gul; Koc, Zafer; Kaniyev, Tahir; Kokangul, Ali (2019)Computed tomography (CT) radiation dose reduction is vital without compromising image quality. The aim was to determine the effects of patient characteristics on the received radiation dose and image quality in chest CT ... -
