  • 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 brain stem with intrathecal metrizamide. Part II 
    Mawad, M.E.; Silver, A.J.; Hilal, S.K.; Ganti, S.R. (2019-07-10)
    The practical usefulness of computed tomography with intrathecal metrizamide in imaging the brain stem is illustrated in six examples where the lesions were misdiagnosed on intravenously enhanced computed tomography, ...
  • 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 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 ...
  • 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 ...
  • Patterns of spinal cord atrophy by metrizamide CT 
    Mawad, M.E.; Hilal, S.K.; Fetell, M.R.; Silver, A.J.; Ganti, S.R.; Sane, P. (2019-07-09)
    Forty patients with cervical myelopathy underwent high-resolution computed tomography (CT) with intrathecal administration of metrizamide for evaluation of cervical spinal cord atrophy. Thirty of them showed evidence of ...
