Radiosurgery for Glossopharyngeal Neuralgia by Constantin TULEASCA, MD, PhD

1:00 pm (Dublin, Edinburgh, Lisbon, London) - 2:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 8:00 am (Eastern time - New York, Canada) - 9:00 am (Brasilia) - 9:00 pm (Tokyo) - 5:00 am (Pacific time - Los Angeles) - 10:00 pm (Brisbane)

Glossopharyngeal neuralgia (GPN) is an extremely uncommon pharyngeal and craniofacial condition of the ninth cranial nerve. Usual clinical presentation consists in attacks of severe electric shock-like pain of the throat, tongue and ear. In rare cases, it can be accompanied by hemodynamic instability, with further syncope or cardiac arrest. 

In this webinar, we review the challenging clinical diagnostic aspects, as well as the therapeutic armamentarium. We further and particularly discuss stereotactic radiosurgery by Gamma Knife as a minimally invasive and valuable management option in drug-resistant GPN.

Pediatric SRS and SBRT by Erin MURPHY, MD, Associate Professor

1:00 pm (Dublin, Edinburgh, Lisbon, London) - 2:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 8:00 am (Eastern time - New York, Canada) - 9:00 am (Brasilia) - 9:00 pm (Tokyo) - 5:00 am (Pacific time - Los Angeles) - 10:00 pm (Brisbane)

Pediatric patients receiving SRS and SBRT are often heavily pretreated and rarely present with oligometastatic disease and therefore can be a challenging population to treat.  However with SRS and SBRT techniques, durable local control is possible for radioresistant histologies. SRS and SBRT are well tolerated as long as we are thoughtful about concurrent therapies. We do not know ideal dose or fractionation schemes and therefore studies are necessary.

MR Imaging Techniques for SRS by Herwin SPECKTER, Medical Physicist

1:00 pm (Dublin, Edinburgh, Lisbon, London) - 2:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 8:00 am (Eastern time - New York, Canada) - 9:00 am (Brasilia) - 9:00 pm (Tokyo) - 5:00 am (Pacific time - Los Angeles) - 10:00 pm (Brisbane)

Imaging for SRS can be more demanding compared to conventional diagnostic imaging. In SRS, high-quality imaging is crucial for the identification and contouring of both lesions and organs at risk. SRS requires high geometric accuracy in order to treat successfully and safely, delivering large doses of radiation with the characteristic steep dose gradient. Imaging can provide additional information about tissue classification, prediction of volumetric control after treatment, and is important in follow up. Topics that will be covered in the talk: MR Hardware tendencies, geometric accuracy, MR-CT coregistration, modern MR sequences, image postprocessing, prediction of volumetric control after SRS, and future directions.

Radiosurgery of Intracranial Extraaxial Malignancies by Yoshimasa MORI, MD, DMSc, IFAANS

1:00 pm (Dublin, Edinburgh, Lisbon, London) - 2:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 8:00 am (Eastern time - New York, Canada) - 9:00 am (Brasilia) - 9:00 pm (Tokyo) - 5:00 am (Pacific time - Los Angeles) - 10:00 pm (Brisbane)

The role of radiosurgery for extraaxial malignancies including chordoma, paraganglioma, non-benign meningioma, hemangiopericytoma, skull-base malignant tumors, and skull-base metastases will be presented.

Multimodality imaging of spinal metastasis by Pejman JABEHDAR MARALANI, MD FRCPC, Assistant Professor

1:00 pm (Dublin, Edinburgh, Lisbon, London) - 2:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 8:00 am (Eastern time - New York, Canada) - 9:00 am (Brasilia) - 9:00 pm (Tokyo) - 5:00 am (Pacific time - Los Angeles) - 10:00 pm (Brisbane)

Spinal metastasis are among the most common sites of cancer metastasis. As stereotactic body radiation therapy to treat spinal metastasis is gaining popularity, precise determination and localization of spinal metastasis is of paramount importance. This lecture reviews different imaging modalities to assess spinal metastasis for both diagnosis and follow up.
