Publication 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 Metadata only Supposed to be rare cause of intestinal obstruction; abdominal cocoon: report of two cases(2013-05-01T00:00:00Z) Serter, Asli; KOCAKOÇ, ERCAN; Cipe, Gokhan; KOCAKOÇ, ERCANAbdominal cocoon, or sclerosing encapsulating peritonitis, is supposed to be rare cause of intestinal obstruction. It is characterized by totally or partially encasement of small bowel with a thick, fibrotic, cocoon-like membrane. We think this entity is not rare as previously thought. We reported two case-s clinical and imaging findings which diagnosed abdominal cocoon by surgery to increase awareness of this diagnosis. (C) 2013 Elsevier Inc.

The ADC values of 73 adrenal lesions (54 benign, 19 malignant) in 69 patients were measured at b 100, 600 and 1000 gradients on diffusion-weighted magnetic resonance imaging (DW-MRI). No statistically significant difference was found between ADC values of benign and malignant adrenal masses, nonadenomatous benign adrenal masses and malignant adrenal masses, adrenal adenomas and nonadenomatous lesions, adenomas and metastases, adenomas and pheochromocytomas, metastases and pheochromocytomas. ADC values are not helpful in the differentiation between solid adrenal masses. (C) 2014 Elsevier Inc.

The ADC values of prostate cancer group were significantly lower than normal prostate and prostatitis group at b 600 and 1,000 s/mm(2) gradients. The ADC values at high diffusion gradients may be used in differentiation prostate cancer from normal prostate and prostatitis.Publication Metadata only Doppler ultrasonography and magnetic resonance imaging findings of testicular adrenal rest tissue in a patient with 11 beta hydroxylase deficiency. Case report(2014-12-01T00:00:00Z) Ahmad, Issam Cheikh; YILMAZ, Temel Fatih; KOCAKOÇ, ERCAN; YILMAZ, TEMEL FATİH; KOCAKOÇ, ERCANBenign intratesticular lesions are rare; thus, radiological diagnosis is important to avoid unnecessary surgical intervention. Testicular adrenal rest tumors (TART) are the nodular testicular lesions deriving from the adrenal remnant tissue reported in patients with congenital adrenal hyperplasia. We present ultrasonographic (US) and magnetic resonance imaging (MRI) findings of intratesticular adrenal rests in a 16-year-old patient with 11 beta hydroxylase deficiency. Scrotal ultrasonography demonstrated bilateral heterogenous hypoechoic lesions located around mediastinum testis and highly vascularized on powerDoppler US. On MRI the lesions were hyperintense on T1-weighted and hypointense on T2-weighted images and enhanced brightly on post-contrast images.Publication Metadata only Diagnosis of Peritoneal Metastases with Abdominal Malignancies: Role of ADC Measurement on Diffusion Weighted MRI(2012-12-01T00:00:00Z) ONUR, MEHMET RUHİ; Akyol, Muammer; POYRAZ, AHMET KÜRŞAD; KOCAKOÇ, ERCAN; Ogur, Erkin; KOCAKOÇ, ERCANObjective: The purpose of our study was to evaluate the utility of the apparent diffusion coefficient (ADC) value measurement in the diagnosis of peritoneal metastases on diffusion weighted magnetic resonance imaging.Publication Metadata only Evaluation of left renal vein entrapment using multidetector computed tomography(2013-03-01T00:00:00Z) POYRAZ, AHMET KÜRŞAD; FIRDOLAŞ, FATİH; ONUR, MEHMET RUHİ; KOCAKOÇ, ERCAN; KOCAKOÇ, ERCANBackground: Nutcracker syndrome, also called left renal vein entrapment syndrome, is a cause of non-glomerular hematuria with difficulties in diagnosis. Multidetector computed tomography (MDCT) is a powerful tool to prevent unnecessary diagnostic procedures.Publication Metadata only Evaluation of normal appendix vermiformis in adults with multidetector computed tomography(2012-11-01T00:00:00Z) Turkoglu, Huseyin; ONUR, MEHMET RUHİ; POYRAZ, AHMET KÜRŞAD; KOCAKOÇ, ERCAN; KOCAKOÇ, ERCANTo determine the utility of different contrast enhancement phases (unenhanced, arterial, and venous), slice thicknesses (0.5, 3, and 5 mm), and planes (axial and coronal) in the evaluation of appendix vermiformis (AV) on multidetector computed tomography (MDCT), CT examinations of 600 patients were obtained. No significant difference was found between the different imaging planes, slice thicknesses, and contrast enhancement phases in terms of detection rates of AV. The mean diameter of AV in the axial plane (5.93 +/- 0.06 mm) was significantly lower than that in the coronal plane (6.18 +/- 0.06 mm). Evaluation of AV on MDCT is enhanced by combined interpretation on axial and coronal planes. (C) 2012 Elsevier Inc.
