Most models interpret the ECG as normal sinus rhythm with some baseline artifact, but one model disagrees, calling it atrial fibrillation with rapid ventricular response and diffuse ischemic ST changes. 🤝 Model Agreement Score: 27/100 📋 Full case & discussion: medicalsphere.ai/cases/e68ce550…

Good afternoon/evening. 57 year old female feeling unwell. Rhythm?. Please. Thank you so much. ❤️💙

All three models agree the diagnosis is Miller Fisher syndrome, a Guillain-Barré spectrum variant characterized by ophthalmoplegia, ataxia, areflexia, and albuminocytologic dissociation, with no major disagreement aside from one noting possible facial diplegia/polyneuritis cranialis overlap. 🤝 Model Agreement Score: 92/100 💡 Explore the complete case: medicalsphere.ai/cases/2240a164…

🤵‍♂️57M with new diplopia → rapid progression to complete ophthalmoplegia, facial diplegia & ataxic gait. 🏥Exam: bilateral CN III, VI, VII palsies + areflexia. CSF: ↑protein, no cells. 👨‍⚕️What’s the diagnosis?

All models agree the image points to the mammillary body, with the key interpretation being Wernicke encephalopathy from alcohol-related thiamine deficiency; there is no notable disagreement beyond minor wording differences about the clinical triad and MRI appearance. 🤝 Model Agreement Score: 97/100 📋 Full case & discussion: medicalsphere.ai/cases/6c7255ae…

Is there a connection between this structure, this protuberance, and alcohol? What's the triad? Drop your thoughts below 👇👇 #FOAMed #Neuroanatomy #Wernicke

All models agree the ECG is sinus rhythm with marked left-axis abnormality consistent with LAFB, but they disagree on the acute significance—one calls it diffuse subendocardial ischemia/high-risk ACS, another interprets it as complete/new LBBB with possible STEMI-equivalent, and the third sees no acute MI. 🤝 Model Agreement Score: 24/100 🔗 See the full analysis here: medicalsphere.ai/cases/b60010bb…

@cingolani_oscar Which AI model did better? 🤔⚔️

We created a thread for this ECG with all the follow-up questions and tested a group of frontier AI models to see how they responded. Here’s how they did: Most models agreed the ECG shows **sinus rhythm with second-degree AV block type I (Mobitz I/Wenckebach)**, based on progressive PR prolongation with grouped beating and a dropped QRS. The main differences were that one model called it **sinus tachycardia + Mobitz I**, while another interpreted it as **PACs in bigeminy** rather than AV block; a rate estimate of about **78 bpm** also appeared, supporting non-tachycardic sinus rhythm. 🔗 Full thread: medicalsphere.ai/cases/28b1ced4…

The models disagree markedly: one interprets the ECG as sinus rhythm with dextrocardia features, another as typical AVNRT, and a third as atrial fibrillation with aberrant conduction (Ashman phenomenon). x.com/i/status/20391…

All models agree that the correct interpretation is to use water-soluble iodinated contrast for suspected GI perforation/perforated ulcer because barium is contraindicated, with only minor disagreement that one model noted barium may sometimes be considered later if initial water-soluble imaging is negative despite high suspicion. x.com/i/status/20388…

The models did not reach consensus: one interpreted the TEE as a large mitral valve vegetation causing severe mitral regurgitation and likely infective endocarditis, while the other diagnosed cor triatriatum sinister with an incidental left atrial membrane. x.com/i/status/20391…

The models agree the echocardiogram is most consistent with rheumatic mitral stenosis, with the only notable disagreement being that one model suggests it is likely severe while the other gives no severity grade. x.com/i/status/20391…

@PedramHosseini @suhail_nasim Most models interpreted the chest X-ray as bilateral cannonball pulmonary metastases, but one model disagreed and favored rheumatic mitral stenosis with pulmonary hypertension. 🤝 Model Agreement Score: 42/100 🔗 See the full analysis here: medicalsphere.ai/cases/e099b1d1…

The models agree this is distal (type 1) renal tubular acidosis causing a normal-anion-gap metabolic acidosis in Sjögren’s syndrome, but they disagree on confirmation testing: two favor a low urine osmolar gap (25 mOsm/kg) while one favors a positive urine anion gap (+25 mEq/L). 🤝 Model Agreement Score: 72/100 🔗 See the full analysis here: medicalsphere.ai/cases/fa5fb085…

The models agree the ECG is abnormal with sinus rhythm and a left-axis/conduction abnormality, but they disagree notably on the exact diagnosis—LAFB with possible digoxin effect or diffuse ischemia, complete LBBB/STEMI-equivalent, or hyperacute anterior MI. x.com/i/status/20390…
