Pearls and Pitfalls of Oncologic Imaging in Neuroradiology - John Heymann

Video Transcription

Video Summary

Dr. John Hyman, a neuroradiologist, presented an advanced lecture on neuro-oncological imaging, imparting valuable insights and practical tips tailored primarily for professionals with experience in interpreting imaging. The lecture encompassed various facets of imaging, including technical details crucial for accurate diagnosis of brain malignancies, such as gliomas and metastases, while emphasizing the importance of understanding imaging study orientation, distinguishing between vasogenic and cytotoxic edema, and the significance of conserved landmarks in imaging. Dr. Hyman highlighted the challenges of interpreting post-treatment scans, particularly regarding distinguishing between pseudoprogression and true progression in tumors. He advised the audience on the potential pitfalls of over-relying on advanced imaging techniques like spectroscopy and emphasized the benefits of using traditional methods like flare imaging for assessing tumors. He stressed the importance of considering clinical contexts and recommended short-term follow-ups to assess progression accurately. The session concluded with a Q&A, addressing issues such as handling radiation necrosis and the use of PET scans in brain tumor imaging, while providing resources for continued learning.
