Bones and MRI, huh? #MRI has long been a cornerstone in medical diagnostics for soft tissue structures. So, you wouldn’t necessarily think of MRI when imaging bones, I mean, no moving protons, what could you possibly see? Go get an #Xray! Well let me tell you what you can see! 🔬 Early Detection of Bone Pathologies: MRI’s superior contrast resolution helps in diagnosing conditions like #osteomyelitis, avascular necrosis, and bone #tumors early, offering a head start in treatment. 🦴 Assessing Bone Quality: Beyond #bone density, MRI evaluates bone microarchitecture, crucial for conditions like osteoporosis, allowing for more effective treatment plans. 🏥 Ligament and Tendon Injuries: MRI’s multi-planar imaging capabilities provide detailed assessments of ligaments and tendons, essential for accurate diagnosis and surgical planning. 🎗️ Oncology Breakthroughs: MRI excels in characterizing bone tumors, monitoring treatment responses, and providing real-time insights into the efficacy of therapies. 🚀 Advanced Techniques: Diffusion-Weighted Imaging (DWI): Detects early bone marrow changes associated with malignancies or infections. Magnetic Resonance Spectroscopy (MRS): Analyzes the chemical composition of tissues for studying bone metabolism. Dynamic Contrast-Enhanced MRI (DCE-MRI): Evaluates the vascularity of bone tumors, aiding in treatment planning. I love how MRI is always evolving and in bone imaging there is promise with emerging techniques like ultrashort echo time MRI and the integration of artificial intelligence (AI) to enhance diagnostic accuracy and efficiency.

🔍 Exciting Research in TAVR Catheter Tracking and Plaque Rupture Risk! 💡 This week, we're diving into the fascinating world of Transcatheter Aortic Valve Replacement (TAVR) procedures with new insights from a recent study on catheter tracking forces and plaque rupture risks. • 📊 The study, which combines experimental and computational methods, sheds light on several critical aspects of TAVR delivery systems. • 📉 One key finding is the comparison of reaction force predictions between in-silico models and in vitro measurements. While the models provided valuable insights into peak reaction forces during catheter tracking, they also revealed an under-prediction compared to the actual forces observed in benchtop testing. This discrepancy highlights the complexities of translating theoretical predictions into real-world scenarios. • 💥 Another significant aspect of the study is the assessment of plaque rupture risk during catheter tracking. Researchers analyzed stress distributions in aortic wall tissue and plaques, demonstrating notable risks of plaque rupture, particularly in models with stiff plaques. This finding underscores the importance of understanding the biomechanical interactions between catheter delivery systems and vessel walls to mitigate potential complications like micro-emboli formation. • 🌐 Furthermore, the study investigated the influence of catheter tip lengths on contact pressures exerted on the aorta wall during tracking. Shorter tip lengths were associated with higher peak contact pressures due to a smaller contact surface area, highlighting the need for optimizing catheter tip design to minimize tissue damage and enhance patient safety. 🫀 At ArchCath, we're committed to advancing technologies that improve the safety and efficacy of complex cardiac procedures like TAVR. While we can't reveal specific details yet, our team is working diligently to develop innovative solutions that address challenges associated with TAVR procedures. 🔗 To read more about this study: https://lnkd.in/df557tmX Stay tuned for more updates as we continue to push the boundaries of heart tech innovation! 💫 #TAVR #CatheterTracking #PlaqueRuptureRisk #HeartTech #Innovation #ArchCath 

MediTech Innovations- Brain-Machine Interface for Amyotrophic Lateral Sclerosis(ALS) ALS is a neurodegenerative disease that attacks nerve cells controlling muscle movement. As the disease progresses, patients lose the ability to speak, swallow, and eventually breathe independently. Communication becomes a major challenge, leaving patients feeling isolated and frustrated. How BCIs Can Help: BCIs offer a potential communication pathway by translating brain signals into commands for computers or assistive devices. By using electrodes placed on the scalp or implanted directly in the brain, BCIs can detect electrical activity associated with thoughts or intentions. Types of BCIs for ALS: Non-invasive BCIs: These use electrodes placed on the scalp (EEG) to detect brain activity. They are relatively inexpensive and easy to set up but may have lower accuracy compared to implanted BCIs. Implantable BCIs: Electrodes are surgically implanted directly on the brain surface or within brain tissue. These offer higher accuracy and signal resolution but are more invasive and require surgery.#medicalinnovation #neuroengineering #BME

Last week we shared a story about research underway at our center and NYU Langone Health's department of orthopedic surgery in which scientists combine advanced MRI with genomics to predict the risk of post-traumatic osteoarthritis (PTOA): https://lnkd.in/edJzxcjt Amparo Ruiz, PhD, who is featured in that story, is also leading a separate investigation supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) at NYU Grossman School of Medicine to develop in vivo MRI biomarkers of PTOA. In this project, Dr. Ruiz and colleagues draw on a wide array of imaging methods to examine whether a peptide called P15-1 can help scientists noninvasively visualize post-injury changes in cartilage. Take a look at the many types of imaging that come together in the investigation: 👀 visual story: https://lnkd.in/e2i2kY9j 📄 blog post: https://lnkd.in/eCtWZ3Tt #MRI #biomarkers of #PTOA and #OA #innovation in #science for #medicine and #jointhealth #radiology #research on #osteoarthritis

📃Scientific paper: POP-Q Versus Upright MRI Distance Measurements: A Prospective Study in Patients with POP Abstract: Introduction and Hypothesis The gold standard for quantifying pelvic organ prolapse is the pelvic organ prolapse quantification (POP-Q) system; however, upright magnetic resonance imaging (MRI) is a promising new method. The objective of this study was to determine the correlation between POP-Q and MRI measurements of the bladder and cervix. Methods This prospective study included patients with prolapse in whom POP-Q points Aa or Ba and C were measured as standard care. MRI scans were performed in an upright position, and the distances of the lowest points of the bladder and cervix to the Pelvic Inclination Correction System (PICS) were calculated. Correlations between POP-Q and MRI-PICS measurements were determined using the Pearson correlation coefficient for normally distributed data and the Spearman’s rank correlation coefficient for non-normally distributed data. Results A total of 63 patients were suitable for analysis. There was a moderate positive correlation between the POP-Q and MRI-PICS measurements for bladder ( r (61) = 0.480, r  < 0.001) and uterus ( r (61) = 0.527, p  < 0.001). Measurement differences between POP-Q and MRI-PICS of the bladder and uterus vary from −3.2 cm to 7.1 cm, and from −2.1 cm to 8.5 cm respectively. In 71.4% of patients more descent was seen on upright MRI than with POP-Q measurement for both bladder and uterus. For patients with similar POP-Q measurements, a high variation in MRI measurements of the bladder and uterus was foun...

This is an amazing and innovative use of AI.

'Virtual biopsy' lets clinicians analyze skin noninvasively with help from Artificial Intelligence. Stanford Medicine researchers have developed a method to penetrate tissue with lasers, creating a high-resolution, three-dimensional image of its cells. April 10, 2024 The new method, published April 10 in Science Advances, could be used to noninvasively scan the skin for unhealthy cells as well as provide rapid results on biopsies taken elsewhere in the body. It could also provide more information than current diagnostic approaches.
