@SharathKumarGG7 Great summary, hopefully notebookLM improves in the future - the FLAIR images seem to be dodgy

🧠👂 Did you know Delayed Contrast-Enhanced MRI is the gold standard for visualizing Menière’s disease in vivo? ​The target: Endolymphatic Hydrops (EH). ​Here is the physiology behind how it works: 💉 Gadolinium slowly crosses the blood-labyrinth barrier into the perilymph (which appears bright) but NOT the endolymph (which remains dark) 🧲 On heavily T2-weighted IR sequences, an enlarged dark area confirms EH! ​#Radiology #MedTwitter #MenieresDisease #MRI #Otology #NeuroRad

@danatsouza Mate! Love it

So honored and excited to share our work in progress RADS project and glad to see how well it was received at #SAR26 in Puerto Rico! We are finally able to address a long overdue gap in Abdominal Radiology: standardizing colonic stool assessment with objective criteria that can guide management and improve outcomes. POO-RADS is a novel, standardized classification system designed to quantify fecal matter in the colon through CT imaging. This five-tier framework replaces vague clinical descriptions with objective measurements based on stool volume, colonic distention, and the physical characteristics of waste. Future Directions - Radiomics and machine learning will improve further our system by analyzing pixel-level data and texture analysis to distinguish between mild retention and critical impaction. Perhaps a future DFP? If you’re interested in collaborating please let me know! @SocietyAbdRad @SAR_RFS @BrighamRad @DGlaucomflecken

@PhilipRChapman1 Insightful overview!

In a patient with prior radiation for nasopharyngeal carcinoma (NPC) or other primary malignant tumor such as adenoid cystic carcinoma, a new intraparenchymal lesion in the anterior temporal lobe is much more likely to represent radiation necrosis than metastatic disease. (Radiation necrosis until proven otherwise) Imaging clues that favor radiation necrosis: -Location: anterior/inferior temporal lobe ( and within radiation field) -Timing: Within first 3 years of radiation -Enhancement: irregular, ring-like or “soap-bubble” -Edema: often disproportionate -Perfusion (DSC MRI): ↓ rCBV -MR spectroscopy: lipid-lactate peaks, ↓ choline Metastasis, while rare, becomes more plausible if: -Lesion is outside radiation field -Multiple lesions in atypical locations (e.g., cerebellum, cortex elsewhere) -Markedly elevated perfusion (high rCBV) -Known systemic metastatic progression

@ActaNeuro Great illustration, something to consider for the future - the carotid siphon is incorrectly depicted lateral to the anterior clinoid process.

Excellent review!

The best thing about a career in radiology is that there's always something new to learn every day! 💡

What is the remote labour index (RLI)? 💻- a benchmark that measures how effectively AI agents can automate real-world, end-to-end remote freelance tasks. It provides an empirical metric for tracking impact on employment, beyond isolated skill tests. arxiv.org/abs/2510.26787

@marclou Mad respect bro. You've been shipping before vibe coding existed.

It's TrustMRR

@drkeithsiau Love it

Immunoglobulins 😅

@francisdeng Interesting learning point. I'm still a believer in phone calls for triaging potentially life-threatening conditions. On many occasions, I've guided junior ED doctors. Based on their history and exam findings, dissection is highly unlikely; it's more likely musculoskeletal.

A medical malpractice case about communication failures around imaging: 🧵 A young, very tall man with chest pain, nausea, and abdominal pain presented to the ED and was worked up by the emergency physician.

@daniel_gewolb @piandro3142 @Radiopaedia Interesting take!

Problem with this study is that it only compares to other tumors but striated enhancement like this with relatively preserved architecture would more likely put inflammatory, infectious and vascular etiologies in the differential rather than a posterior fossa glioma or met. So needs to compare to non-neoplastic causes

Branch-like enhancement may distinguish cerebellar lymphoma from other cerebellar lesions. In this study, 90% of lymphomas had this pattern, compared to 5% of patients with other lesions. pmc.ncbi.nlm.nih.gov/articles/PMC88… Great @Radiopaedia case demonstrating this: radiopaedia.org/cases/cerebell…

What's your go-to protocol for suspected occult scaphoid? #Radiology #FOAMed #MedTwitter #mskrad #radres #msk #ortho

Management? 🩹 Negative X-ray but high clinical suspicion → immobilize (thumb spica cast) + F/U imaging (MRI). Confirmed non-displaced fracture → cast 6-12 weeks. Displaced / unstable / proximal pole → urgent ortho referral for fixation. Early Dx prevents complications!

✋Occult Scaphoid Fractures (a thread 🧶..) Fall on an outstretched hand (FOOSH) + pain in the anatomical snuffbox → high clinical suspicion. Up to 5-20% of scaphoid fractures are radiographically occult initially. Missed diagnosis risks non-union + AVN of the proximal pole!

Management of femoral neck stress fractures? - Non-op for compression-sided (medial) fractures <50% neck width. - If tension-side (lateral) or >50% neck width = ortho opinion for cannulated screw fixation. An early catch key in athletes! #Radiology #FOAMed

Diagnosis? Radiographic changes can lag behind clinical symptoms and are often negative. MRI is the gold standard for diagnosis, if clinically indicated. Case courtesy of Andrew Dixon, Radiopaedia.org, rID: 34081

MSK Exam Topic: Femoral Neck Stress Fractures (FNSF) 🦴 Repetitive loading on the femoral neck may cause non-displaced stress fractures, which may be either on the compression side (inferior-medial) or tension side (superior-lateral). Runners and military folk, watch out! 🏃
