Can you improve this?? ✅While wireless and traditional ultrasound showed high reliability for cartilage thickness, ❌low reliability for echo-intensity persisted, even after pixel normalization.😕 ⚡This points to room for improvement in ultrasound tech! 📷Examples across scanners & normalization

🏆 Wireless ultrasound is a game-changer! 🔬 Our new study in Osteoarthritis Imaging confirms that Clarius wireless ultrasound probes accurately measure knee cartilage thickness—comparable to traditional systems. 📊 A big step toward more accessible ultrasound technology! 🔗: doi.org/10.1016/j.os...

Adding this post to the science🧪 feed! 🚨 Ultrasound + Bone Shape = New Research! 🚨 We developed a novel B-Score 🧮 using an ultrasound-based statistical shape model 🩻 to measure femoral bone shape post-ACLR 🦵 ✅ Accessible ✅ Accurate (92%!) ✅ Early detection potential 📖 LINK👉shorturl.at/lto3A
Development of SSM and B-Score Process. Overview of the process to develop the statistical shape model (SSM) and B-score. Bone Line Registration: Three ultrasound images from one knee are acquired and their cartilage segmented; the bone line is then extracted from the cartilage and normalized. Statistical Shape Modeling: PCA is performed to obtain shape feature scores for each bone line. Bone Shape Scoring: Bone line shape feature scores are projected onto the ACLR vector, resulting in the B-Score.

📈Bone Shape Comparison 🦵 🔍 Ultrasound-based B-Score captures subtle but significant differences in femoral trochlear bone shape: 🟦 Healthy = Deeper trochlear groove 🟥 ACLR = Flatter groove ✨ B-Score thresholds identify these changes with 99% shape variance explained ✅.

📊 B-Score Accuracy 🎯 We validated our ultrasound-based B-Score to classify femoral bone shape post-ACLR 🦵 ✅ 92% Accuracy 🏆 ✅ High Sensitivity (97%) 📈 ✅ Clear separation of ACLR (🔴) vs. Healthy (🔵). B-Score = a promising tool for detecting post-ACLR bone changes early!
