  • Aneurysm ostium angle 
    Yasuda, R.; Arat, A.; Strother, C.M.; Aagaard-Kienitz, B.; Niemann, D.; Mohamed, A.; Royalty, K.; Pulfer, K.; Taki, W.; Mawad, M.E. (2019-07-10)
    BACKGROUND AND PURPOSE: There is no satisfactory parameter that can predict the need for assistant devices for endovascular aneurysm coiling. Our aim was to evaluate the utility of MOA as a predictor of the need for ...
  • Computed tomography of primitive neuroectodermal tumors 
    Ganti, S.R.; Silver, A.J.; Diefenbach, P.; Hilal, S.K.; Mawad, M.E.; Sane, P. (2019-07-09)
    The primitive neuroectodermal tumor is a neoplasm of young individuals that occurs predominantly in the supratentorial compartment. It appears on computed tomography as a bulky mass, often with calcification with predominantly ...
  • Computed tomography of the anteverted internal auditory canal 
    Silver, A.J.; Jahn, A.F.; Mawad, M.E.; Ganti, S.R.; Hilal, S.K. (2019-07-11)
    A symmetric variation in the course of the internal auditory canals, visualized best on axial computed tomographic views with thin sections, was observed in three of 75 patients examined mainly for hearing, vestibular, and ...
  • Computed tomography of the brain stem with intrathecal metrizamide. Part I 
    Mawad, M.E.; Silver, A.J.; Hilal, S.K.; Ganti, S.R. (2019-07-09)
    In summary, the anatomic details of the brain stem are exquisitely demonstrated with metrizamide CT. The obex is the zone of transition from the closed medulla, which has a conical pear-shaped appearance to the quadriconcave ...
  • Computed tomography of the carotid space and related cervical spaces. Part I 
    Silver, A.J.; Mawad, M.E.; Hilal, S.K.; Sane, P.; Ganti, S.R. (2019-07-12)
    The carotid space, parapharyngeal space, and paraspinal space are described. The carotid space is shown on computed tomography (CT) to be posterior to the parapharyngeal space and separated from it by the styloid apparatus. ...
  • Computed tomography of the carotid space and related cervical spaces. Part II 
    Silver, A.J.; Mawad, M.E.; Hilal, S.K.; Ascheri, G.F.; Chynn, K.Y.; Baredes, S. (2019-07-11)
    Fourteen neurogenic tumors of the neck were examined with computed tomography (CT) and, in ten cases, angiography. Schwannomas and paragangliomas occurred in the carotid space. These tumors could be distinguished on CT ...
  • Computed tomography of the cervical lymph nodes 
    Silver, A.J.; Mawad, M.E.; Hilal, S.K.; Ellis, K.; Ganti, S.R.; Sane, P.; Blitzer, A. (2019-07-11)
    Intravenous contrast administration increases the sensitivity of computed tomographic scanning for enlarged cervical lymph nodes but requires a detailed knowledge of neck anatomy, especially in order to distinguish certain ...
  • Computed tomography of the nasopharynx and related spaces. Part I 
    Silver, A.J.; Mawad, M.E.; Hilal, S.K.; Sane, P.; Ganti, S.R. (2019-07-11)
    The normal computed tomographic anatomy of the nasopharynx and pterygopalatine and infratemporal fossae is analyzed. Particular attention is given to the distinction between deglutitional and masticatory muscles. The ...
  • Computed tomography of the nasopharynx and related spaces. Part II 
    Silver, A.J.; Mawad, M.E.; Hilal, S.K.; Sane, P.; Ganti, S.R. (2019-07-11)
    Malignant tumors of the nasopharynx were analyzed by region of origin and route of spread. Nasopharyngeal carcinomas produced early submucosal infiltration of the deglutitional muscle layer with enlargement of the levator ...
  • CT and angiography of primary extradural juxtasellar tumors 
    Moore, T.; Ganti, S.R.; Mawad, M.E.; Hilal, S.K. (2019-07-09)
    The computed tomographic and angiographic features of 15 histologically proven primary extradural juxtasellar tumors were retrospectively reviewed. Five chordomas were characterized by prominent bone erosion and a significant ...
  • Effect of structural remodeling (retraction and recoil) of the pipeline embolization device on aneurysm occlusion rate 
    Jou, L.-D.; Mitchell, B.D.; Shaltoni, H.M.; Mawad, M.E. (2019-07-12)
    BACKGROUND AND PURPOSE: During endovascular treatment of unruptured aneurysms with the Pipeline Embolization Device, an oversized device is often selected to achieve better wall apposition; however, this device oversizing ...
  • Endovascular recanalization in acute ischemic stroke using the solitaire FR revascularization device with adjunctive C-arm CT imaging 
    Mitchell, B.D.; Chinnadurai, P.; Chintalapani, G.; Morsi, H.A.; Shaltoni, H.; Mawad, M.E. (2019-07-12)
    In this clinical report, we examined a single-center experience by using the Solitaire FR Revascularization Device in the treatment of acute ischemic stroke in which there was poor initial visualization of the occluded ...
  • Intimal thickening after placement of a neuroform stent 
    Lee, D.H.; Arat, A.; Mosri, H.; Diaz, O.; Jou, L.-D.; Mawad, M.E. (2019-07-10)
    Little attention has been given to the intimal thickening of the parent artery associated with the use of Neuroform stent. The purposes of this study were are to analyze quantifyanalyze the incidence of the parent artery ...
  • Metastatic adenocarcinoma to the brain 
    Carrier, D.A.; Mawad, M.E.; Kirkpatrick, J.B.; Schmid, M.F. (2019-07-09)
    PURPOSE To describe the appearance on T2-weighted scans of metastatic adenocarcinoma to the brain and to show that the hypointensity frequently associated with these lesions is not related to the presence of mucin, blood ...
  • MR appearance of an orbital leiomyoma 
    Carrier, D.A.; Mawad, M.E.; Kirkpatrick, J.B. (2019-07-10)
    The authors describe the MR appearance of an intraconal orbital vascular leiomyoma that probably arose from smooth muscle in the wall of a vein. Cavernous hemangiomas, schwannomas, neurofibromas, and other well-encapsulated ...
  • Neck localization and geometry quantification of intracranial aneurysms 
    Sgouritsa, E.; Mohamed, A.; Morsi, H.; Shaltoni, H.; Mawad, M.E.; Kakadiaris, I.A. (IEEE, 2019-07-10)
    We present an approach for accurate localization of the neck of intracranial aneurysms and quantification of their geometry that is useful for their treatment through endovascular embolization. In particular, we first ...
  • Occlusive vascular disease associated with cerebral arteriovenous malformations 
    Mawad, M.E.; Hilal, S.K.; Michelsen, W.J.; Stein, B.; Ganti, S.R. (2019-07-11)
    Selective carotid angiography and computed tomography were used in a study of the association of occlusive vascular disease with cerebral arteriovenous malformations in 13 patients. The arterial occlusions ranged from focal ...
