  • intracranial
  • CT scans are used by physicians specializing in treating the eye (ophthalmologists) to detect foreign bodies (especially metallic objects), fractures, abscesses, cellulitis, sinusitis, bleeding within the skull (intracranial bleeding), proptosis, Graves disease changes in the eye, and evaluation of the orbital apex and cavernous sinus. (wikipedia.org)
  • Magnetic resonance imaging (MRI) of the head provides superior information as compared to CT scans when seeking information about headache to confirm a diagnosis of neoplasm, vascular disease, posterior cranial fossa lesions, cervicomedullary lesions, or intracranial pressure disorders. (wikipedia.org)
  • Bone
  • The skull base includes the frontal bone, the sphenoid bone, the temporal bone, and the occipital bone. (mhmedical.com)
  • The hypoglossal canal is a foramen in the occipital bone of the skull. (wikipedia.org)
  • Soft-tissue neoplasms such as pleomorphic undifferentiated sarcoma (malignant fibrous histiocytoma) that erode into adjacent bone may also have a similar appearance. (wikipedia.org)
  • tissue
  • A novel graft material for preventing cerebrospinal fluid leakage in skull base reconstruction: technical note of perifascial areolar tissue. (semanticscholar.org)
  • This is distinctly different from an encephalocele, which is a herniation of brain tissue and/or leptomeninges, that develops through a defect in the skull, where there is a continuity with the cranial cavity. (wikipedia.org)
  • Definitive diagnosis is based on a tissue biopsy. (wikipedia.org)
  • neurological
  • If there is concern about a skull fracture, focal neurological symptoms present or worsening symptoms, then CT imaging may be useful. (wikipedia.org)
  • centers
  • By 2010 these facilities were joined by an additional seven regional hospital-based proton therapy centers in the United States alone, and many more worldwide. (wikipedia.org)
  • brain
  • Proper therapeutic management of brain injury is based on correct diagnosis and appreciation of the temporal course of the disease process. (wikipedia.org)
  • CT scans of the head can confirm a diagnosis of skull fracture or brain bleeding, but even in the emergency room such things are uncommon and not minor injuries so CT of the head is usually not necessary. (wikipedia.org)
  • In these cases, untreated survival usually amounts to only a few months, and survival with current radiation and chemotherapy treatments may extend that time from around a year to a year and a half, possibly two or more, depending on the patient's condition, immune function, treatments used, and the specific type of malignant brain neoplasm. (wikipedia.org)
  • proton
  • The world's first hospital-based proton therapy center was a low energy cyclotron centre for ocular tumours at the Clatterbridge Centre for Oncology in the UK, opened in 1989, followed in 1990 at the Loma Linda University Medical Center (LLUMC) in Loma Linda, California. (wikipedia.org)
  • clinical
  • Even in emergency situations, when a head injury is minor as determined by a physician's evaluation and based on established guidelines, CT of the head should be avoided for adults and delayed pending clinical observation in the emergency department for children. (wikipedia.org)
  • Clinical trials have shown the efficacy and safety of using CT of the head in emergency settings only when indicated, which would be at the indication of evidence-based guidelines following the physical examination and a review of the patient's history. (wikipedia.org)
  • lung
  • Lung cancer is an extremely heterogeneous family of malignant neoplasms, with well over 50 different histological variants recognized under the 4th revision of the World Health Organization (WHO) typing system ("WHO-2004"), currently the most widely used lung cancer classification scheme. (wikipedia.org)
  • Removal
  • This can include removal of the tonsils, adenoids, uvula and edge of the palate, and/or part of the base of the tongue. (wikipedia.org)
  • When removal of the base of the tongue is necessary, it can be removed in one of two ways. (wikipedia.org)
  • acoustic
  • In transcranial magnetic resonance-guided focused ultrasound (tcMRgFUS) treatments, the acoustic and spatial heterogeneity of the skull cause reflection, absorption, and scattering of the acoustic beams. (stanford.edu)
  • The authors then validate and compare the predicted skull efficiencies to an experimental metric based on the subject thermal responses during tcMRgFUS treatments in a dataset of seventeen human subjects.Seventeen human head CT scans were used to create tissue acoustic models, simulating the effects of reflection, absorption, and scattering of the acoustic beam as it propagates through a heterogeneous skull. (stanford.edu)
  • Other tumours which can compress facial nerve along its course like congenital cholesteatomas, hemangiomas, acoustic neuromas, parotid gland neoplasms, or metastases of other tumors. (wikipedia.org)
  • findings
  • Gardner syndrome can be identified based on oral findings, including multiple impacted and supernumerary teeth, multiple jaw osteomas which give a "cotton-wool" appearance to the jaws, as well as multiple odontomas, congenital hypertrophy of the retinal pigment epithelium (CHRPE), in addition to multiple adenomatous polyps of the colon. (wikipedia.org)
  • Conditions
  • There do not seem to be differences in the clinical manifestations (the symptoms or observable conditions which are seen as a result of 1p36) based on whether the deletion is on the paternal or maternal chromosome. (wikipedia.org)
  • Gorlin syndrome List of cutaneous conditions List of dental abnormalities associated with cutaneous conditions List of cutaneous neoplasms associated with systemic syndromes Rapini, Ronald P. (wikipedia.org)
  • less
  • More than 70% involve the maxilla (usually maxillary anterior alveolar ridge), while the mandible and skull are affected less often. (wikipedia.org)
  • include
  • Current TORS techniques include radical tonsillectomy, resection of palate and base of skull tumors, hemiglossectomy and resection of tumors above and involving the larynx. (wikipedia.org)
  • This can include removal of the tonsils, adenoids, uvula and edge of the palate, and/or part of the base of the tongue. (wikipedia.org)
  • The extracolonic tumors may include osteomas of the skull, thyroid cancer, epidermoid cysts, fibromas, as well as the occurrence of desmoid tumors in approximately 15% of affected individuals. (wikipedia.org)
  • particular
  • Since, each model represents distinctly different pathophysiological features related to ICH, use of a particular model may be selected based on what aspect of the disease is to be studied. (jove.com)
