    A Case of Anomalous Origin and Course of Vertebral Artery in a Patient with Klippel Feil Syndrome
    (Korean Radiological Soc, 2016) Ulusoy, Onur Levent; Sasani, Hadi; Barlas, Sezgi Burcin; Mutlu, Ayhan; Sasani, Mehdi
    Patients with Klippel-Feil syndrome (KFS) have an increased incidence of vascular anomalies as well as vertebral artery (VA) anomalies. In this article, we presented imaging findings of a 15-year-old female patient with KFS with a rare association of extraforaminal cranially ascending right VA that originated from the ipsilateral carotid bulb. Trifurcation of the carotid bulb with VA is a very unusual variation and to the best of our knowledge, right-sided one has not been reported in the literature.

    Comparison of 3d reformat computed tomography images using different softwares: do they have an incremental value in 3D imaging?
    (Allied Acad, 2017) Sasani, Hadi; Kayhan, Arda; Gokbay, Inci Zaim; Sasani, Mehdi; Kose, Soner; Gokce, Alper; Karatas, Dilek
    Three dimensional (3D) imaging gained an important diagnostic role because of providing the precise diagnosis in computed tomography (CT) studies. Various 3D softwares such as; VitreaWorkstation - Toshiba, Japan; OsiriX-Switzerland; Volume Viewer-General Electric, USA have been manufactured to improve its diagnostic ability. Providing the deep sense and dimensional perception, the aim of this prospective study is to compare the native 3D (N3D) CT images with 2 anaglyph images by using different softwares and delineate their contribution to 3D CT imaging.

    Imaging Findings of the Morel-Lavellée Lesion
    (2020) Ulusoy, Onur Levent; Sasani, Hadi; Alis, Deniz; Ustabaşıoğlu, Fethi Emre; Barlas, Burçin Sezgi; Onat, Levent; Çolakoğlu, Bülent
    Introduction: This study aims to evaluate the magnetic resonance imaging (MRI) findings of the Morel-Lavellée lesion (MLL),which described as degloving injury of the subcutaneous fatty tissue.Methods: MRI features of fifteen patients in whom the diagnosis of MLL was established by clinically or surgery retrospec-tively analyzed.Results: All the lesions were located in the lower extremities, and 86.6% (n=13) were located at the knee level or above. Alllesions had an anatomic relationship with deep fascia. The majority of the lesions were in either fusiform or crescentic form.60% (n=9) of the lesions showed a well-defined smooth contour. Pseudocapsules were observed in nine patients (60%).46.6% (n=7) of the lesions had a homogeneous signal property. The intralesional hemorrhagic signal was observed in 26.6%(n=4) of the lesions and intra-lesional fat signal in 46.6% (n=7). One patient had fluid-fluid leveling. In two cases, muscleinjury were accompanied by the MLL. In all cases, no associated bone lesion was noted.Discussion and Conclusion: MLL should be considered if a well-circumscribed, crescentic or fusiform subcutaneous masslesion in association with the deep fascia is present, especially in the presence of a history of previous trauma.

    Signal analysis of pineapple according to its anatomical region in magnetic resonance cholangiopancreatography: Which region is most effective in suppressing gastric fluid signal?
    (Allied Acad, 2017) Sasani, Hadi; Kayhan, Arda; Sasani, Mehdi; Sasani, Mahmut
    suppress gastric fluid signal and prevent superimposition artefacts in Magnetic Resonance Cholangiopancreatography (MRCP) examination. The aim of this study is to in vitro investigate the effective usage of pineapple by depicting the signal characteristics of its morphological regions and its signal characteristics. Materials and methods: Five naturally harvested pineapple were examined in axial-coronal planes using TSE-T2 (Turbo spin echo) sequences in a 1.5 T MR device. The plant was divided into apical, mid-cranial, middle, mid-caudal and basal levels. In each level, 10 randomized sampling were obtained from ovary, sepal and peduncle segments using ROI. Pineapple juice was used as control group. Results: The average signal obtained from a total 50 control group was 58.55 +/- 12.47; from sepal, peduncle and ovary segments in 5 pineapple was 27.25 +/- 3.90, 194.63 +/- 62.38 and 166.2 +/- 31.3, respectively (p<0.001, p<0.005). The average signal of sepal segment was lower than control group (p<0.001). Conclusion: Concentrated pineapple juice that is routinely used in MRCP examination is a mixture of sepal, ovary and peduncle segments which may cause global increase in signal intensity and decrease homogeneity. Sepal parts of the fruit shows lowest signal suppression on MRCP sequences may have effective gastric fluid signal suppression.
