Öğe Acromesomelic-spondyloepiphyseal dysplasia associated with congenital optic atrophy: Report of a family(Springer-Verlag, 1993) Sener R.N.; Ustun E.E.; Özkınay, Cihangir; Memis A.; Oyar O.We report a family with a unique combination of radiological manifestations of acromesomelic dysplasia and spondyloepiphyseal dysplasia in two members (a man and his daughter) associated with congenital optic atrophy in four generations. The inheritance pattern of this complex anomaly appeared to be autosomal dominant. © 1993 Springer-Verlag.Öğe Hypoplasia of the left lobe of the liver [7](1992) Sener R.N.; Yorulmaz I.; Oyar O.; Alper H.[No abstract available]Öğe Identification of gunshot projectiles retained in the body by radiological imaging methods [Atesli silah yaralanmalarinda vucuda saplanan yabanci cisimlerin radyolojik goruntuleme yontemleri ile belirlenmesi](1997) Oyar O.; Hanci I.H.In this article, different radiological imaging methods and their functions are presented, to determine gunshot projectiles if it is retained in the body or not and to find out its location by radiological imaging methods. Conventional X ray radiographs, which is easy to reach, practical and superiority of identification of metallic particles, is the most preferable imaging method. On the other hand, if technics used is not enough and radiographs didn't obtained in two different projections, the location and size of the projectiles retained in the body may mislead us. In addition, non-metallic projectiles are not identified on radiographs. To determine metallic and non-metallic shotgun projectiles and their size and location in the body we use computed tomography (CT) too. On the other hand, in too dense projectiles, it may cause image artefact. Non-metallic projectiles, we may use ultrasonography (US) and magnetic resonance imaging (MRI), but none of these methods are useful to determine shotgun projectiles in the body. Moreover, MRI is contraindicate it there is any metallic subject on the body.Öğe Peutz-Jeghers syndrome: CT and US demonstration of small bowel polyps(Springer-Verlag, 1991) Sener R.N.; Kumcuoglu Z.; Elmas N.; Oyar O.; Tugran C.A family affected with Peutz-Jeghers syndrome is reported with an emphasis on radiological findings. A patient showed extensive pigmentation around the lips, buccal mucosa, and nose. Another showed prolonged transient intussusception of a jejunal loop on barium meal examination, and massive rectal bleeding. In this patient, small bowel polyps could also be seen on ultrasonography (US) and computed tomography (CT). On CT several polyps, up to 3 cm in size, were detected along with a "carpeting" pattern of several loops presumably caused by multiple small polyps. © 1991 Springer-Verlag New York Inc.Öğe Prediction of late complication of femoral neck fractures by MRI [COCUK FEMUR BOYUN KIRIKLARINDA GEC DONEM KOMPLIKASYONLARININ ERKEN TANISINDA MAGNETIK REZONANS GORUNTULEMENIN YERI](1994) Aktug K.; Oyar O.; Hanci H.; Oncag H.Femoral neck fractures in children are uncommon injuries and are often associated with excessive incidence of complications, such as avascular necrosis. Precise and early close reduction, surgical fixation, long immobilization, delayed weight bearing and late follow up are mandatory to decrease the amount and severity of complication. Between 1990 and 1992, seven cases with this injury were treated at the Department of Orthopaedics and Traumatology of Ege University Medical School. A prospective study was undertaken to determine the value of MRI in predicting avascular necrosis of the femoral head following femoral neck fractures. MRI was carried out in 7 patients 1 year after first operation. In the MRI Stage I avascular necrosis. All the patients were followed up for at least 1 year. The results indicate that postoperative MRI is useful in children to predict avascular necrosis of femoral head. MRI has been found to be accurate in predicting this complication following femoral neck fractures. It is agreed that MRI have great importance in preparing the medicolegal reports and establishing the prediction of late complication in the follow up of femoral neck fractures of the children.Öğe Radiologic imaging procedures during pregnancy: Safety and risks [Gebelikte radyolojik görüntüleme yöntemleri](2001) Oyar O.Many women become ill while pregnant and require acute medical care, including radiologic examinations with ionizing radiation. In this review; radiologic imaging methods can be used during pregnancy, it's safety and risks to the fetus are discussed. There have been no reports of documented adverse fetal effects for diagnostic ultrasound and magnetic resonance imaging. It is not recommended the diagnostic x-ray procedures should not be performed during pregnancy unless the information to be obtained by other means especially ultrasound, although, the x-ray exposure from a single diagnostic procedure doesn't result in harmful fetal effects.Öğe Ruptured pulmonary hydatid cyst and folded membrane on CT [1](1992) Maden N.; Oyar O.; Tekin U.; Ozer H.[No abstract available]
