Recurrent brain tumor versus radiation necrosis; can dynamic susceptibility contrast (DSC) perfusion magnetic resonance imaging differentiate?
Conclusions DSC-perfusion MRI is a valuable non-invasive tool besides conventional MRI whenever available to differentiate between radiation injury changes and tumor recurrence.
In conclusion, our results suggested that AVNP2 could have an effect on the peri-tumor environment, obviously restraining the growth progress of gliomas, and eventually improving cognitive levels in C6-bearing rats.
ConclusionThis is the first report of a PXA patient receiving therapy with BRAF MEKi and an autophagy inhibitor with prolonged stable disease. This patient highlights the importance of a molecular interrogation in gliomas to provide an integrated diagnosis and effective treatment. This may be useful in up to 3% of glioma patients withBRAF mutations. Molecular testing in neuro-oncology is providing new avenues of diagnosis and treatment, and detailed molecular interrogation should be considered routine.

CONCLUSIONS: A universal method of DTI of the CST was not developed. However, we found that the CP or the PLIC (with or without FL as the second ROI) should be used to outline the CST. PMID: 32073136 [PubMed - as supplied by publisher]
Brain surgery is getting smarter. The journal Nature Medicine recently published a study that found a new imaging technique that allows pathologists to diagnose brain tumors faster and more accurately than ever before. The study focused on Invenio Imaging technology ’s use of artificial intelligence (AI) in making accurate diagnoses. So, will computers replace doctors? That’s […]Find jobs at Careers by KevinMD.com.

We describe a case of a right-handed, 42-year-old, Caucasian female patient who manifested a set of unusual adverse effects during maintenance ultrabrief right-unilateral electroconvulsive therapy (ECT)—generalized myoclonic secondary seizure with lateralization nonresponsive to repeated intravenous diazepam application, deviation of the tongue and the head to the left, ping-pong gaze with nystagmoid jerks, postictal hypoactive confusion state lasting 15 minutes (with a total time to recovery 30 minutes), and likely Todd's paralysis after the procedure (subsided within 24 hours). These adverse effects led to a thorou...
ConclusionBoth FTumor and TTumor presented an intact global topology and altered regional topology related to cognitive impairment and may also share the convergent and divergent regional topological organization of WM structural networks. This suggested that a compensatory mechanism plays a key role in global topology formation in both FTumor and TTumor patients, and as such, development of a structural connectome for patients with brain tumors would be an invaluable medical resource and allow clinicians to make comprehensive preoperative planning.
Myeloid cells that infiltrate into brain tumors are deactivated or exploited by the tumor cells. We previously demonstrated that compromised microglia, monocytes, and macrophages in malignant gliomas could be reactivated by amphotericin-B to contain the growth of brain tumorinitiating cells (BTICs). We identified meclocycline as another activator of microglia, so we sought to test whether its better-tolerated derivative, demeclocycline, also stimulates monocytes to restrict BTIC growth. Monocytes were selected for study as they would be exposed to demeclocycline in the circulation prior to entry into brain tumors to become...
