Hi, I’m Dr. Nikhil R M — Pediatric Neuroradiologist & Director @ Sigma Imaging. Sharing insights on Neuro MRI, ASL Perfusion & Pediatric Brain Imaging. SPIN Fellow (Pediatric Neuroradiology) | #NeuroRad #AIrad #Radiology Let’s connect to learn, share & collaborate! DMs Open.

Q) A 24-year-old man p/w a 10-year hx of recurrent episodes of throbbing, occipital headache along with complex visual symptoms, lasting from a few minutes to an hour. Labs w/⬆️IgA antiTTG & anti endomysial antibodies. What is the likely diagnosis? A. Crohn Disease B.

🧵 SPIN Tweetorial Wednesday The Perirolandic Sign — Why It Matters in POLG Disease DOI: 10.3174/ajnr.A6514 Today we go beyond description → into why the imaging looks the way it does, how patterns evolve, and how to infer POLG early, before catastrophic events.

A young student once asked a wise Monk.... MUST READ.. 🧵

Another great example of likely FCD with good PET, MELD-GRAPH, MP2RAGE and EDGE-enhanced correlation, stressing the importance of multiparametric/multidisciplinary approach in epilepsy! (shout out to the GOSH NRAD team who picked up the lesion and the MELD project)

A must read for #NeuroRad

This has been one the worst, annoying 3T MRI gifts to medical imaging, appears tackled wonderfully here!

⭐️ What is the most likely diagnosis in this 60 y/o M who initially presented w/ unsteady gait, dysarthria and diplopia following a flu-like illness? Symptoms improved with steroids then months later he developed progressive R weakness, incontinence, aphasia & apathy? 🔷1st

spinal Leptomeningeal enhancement can be a feature of Myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), especially in children. https://t.co/DDkOe5CYhc

Post-op epilepsy MR check: 1️⃣ What was done (type-extent) 2️⃣ Mesial structures /callosum / disconnections complete 3️⃣ Residual lesion or abnormal cortex at margins 4️⃣ Complications (bleed, infarct, hydrocephalus) 5️⃣ Any other epileptogenic substrate elsewhere #NeuroRad #Epilepsy

21Y/F, operated right frontal cavernoma. Follow-up 3T MRI: cystic gliosis/encephalomalacia with ex-vacuo ventricle, plus a small stable SWI-blooming focus in subcortical U-fibres → chronic blood products + tiny residual cavernoma, no new bleed. #RadTwitter #NeuroRad #Cavernoma

Grateful for @Radiopaedia and its founder @frankgaillard, team, feeders for years of tireless work making radiology learning accessible. Was revisiting brainstem tegmentum anatomy on https://t.co/mDeQiVR2bK with that beautiful image and just had to say thank you. 🙏

Often neglected and previously imaged with serial Xrays and ct head sometime; radiologist should look out of the box and have a Checklist before signing of the reports.

31-yr pregnant lady (3 mo ANC) with hyperemesis, giddiness, vomiting & new vertical nystagmus. MRI brain: bilateral medial thalamic + subtle periaqueductal FLAIR/DWI signal; MRV normal → acute Wernicke encephalopathy, not CVST or infarct. #FOAMed #NeuroRad #Wernicke
