Thoracic ultrasound (TUS) is a non-invasive imaging technique used to evaluate the structures within the thoracic cavity, including the lungs, pleura, and chest wall. It is highly effective in diagnosing pleural effusions, pneumothorax, and other pulmonary conditions. TUS offers real-time visualization, making it a valuable tool for guiding procedures like thoracentesis. Its advantages include being radiation-free, portable, and relatively easy to perform at the bedside, enhancing its utility in various clinical settings. Traditionally, we used clinical examination to access the lung fields but now it is better to add Lung USG to increase the accuracy for prompt diagnosis.

Non-Contrast MRA Techniques, Principles, and Applications by Ananya Panda, MBBS, MD, FRCRa, Christopher J. Francois, MDb, Candice A. Bookwalter, MDb, Abhishek Chaturvedi, MDc, Jeremy D. Collins, MDb, Tim Leiner, MD, PhDb, Prabhakar Shantha Rajiah, MBBS, MD, FRCRb. The authors discuss various techniques for bright-blood (BB) non-contrast magnetic resonance angiography (MRA), emphasizing their clinical utility and limitations: 1. Balanced Steady-State Free-Precession (b-SSFP): o Rapid imaging technique. o Uses the high T2/T1 ratio of blood for excellent visualization of both arteries and veins. 2. Time-of-Flight (TOF) MRA: o Relies on inflow-related enhancement. o Primarily used in neurovascular imaging. 3. Cardiac Phase-Dependent, Flow-Based Techniques: o Includes techniques such as subtractive fast spin-echo, Quiescent Interval Steady-State (QISS), and three-dimensional b-SSFP with flow-sensitive dephasing. o Commonly used for peripheral extremity angiography. 4. Phase-Contrast MRA: o Velocity-sensitive technique. o Offers both anatomical information and flow quantification. 5. Arterial Spin Labeling (ASL) MRA: o Widely used for renal MRA. o Can be tailored for cerebral, carotid, hepatic, and pulmonary circulations. 6. New Multi-Contrast Techniques: o Allows simultaneous evaluation of vessel wall (black-blood) and luminal (bright-blood). o Particularly useful for carotid and cardiovascular imaging. Each technique has specific advantages depending on the region of interest and the clinical scenario. #Magneticresonance #Noncontrastangiography #Magneticresonanceangiography #Renalartery #Pulmonary #Cerebral #Flowmeasurement #CircleofWillis #carotid #Aorto_iliacMRA #PeripherallimbMRA 

🏥🇷🇪➡️🫀#Rotablator with the #new #FLOPPY guide #rotawiredrive by Boston Scientific (collaboration with ASAHI INTECC Europe B.V. ) on a 79 yo patient, #NSTEMI with positive troponins, known to have a native coronary network with previous triple vessel bypass grafting. 🆗LIMA to the LAD II. ❌Sequential saphenous vein bypass to the second marginal and the posterior interventricular artery not visualized due to known occlusion. ❌Significant calcified stenosis at the ostium of the proximal circumflex artery and intermediate lesion of the mid circumflex artery. 🪨💉Left radial distal artery angioplasty (Terumo) was performed using a 6F EBU4.0 guiding catheter (Medtronic). 🪡✅The calcified lesion in the circumflex artery was successfully crossed using this #rotawiredrive #guide with good maneuverability and ease 🆗 ❕❗️❕ 🌪️✅Rotablation (Boston Scientific Cardiology) was performed using a 1.5 mm burr 🍓. 🎈✅Pre-dilation was done with a non-compliant 3.0x20 balloon. 🌪️✅💥Placement of a 3.5x38 stent was easily achieved. 💥💥Stent boost was performed to assess stent expansion. 🎈✅ To optimize stent deployment at the ostium of the LMA, a non-compliant balloon 5.00x20mm was used. 🎈✅ To optimize angioplasty of the ostium of the proximal circumflex artery, a non-compliant balloon 3.5x15mm balloon was used. 🌪️✅💥 Stent 3 x 15 mm was deployed in the mid circumflex artery distal to the previous stent. ✅✅✅Angioplasty was successful. ❗️❗️❗️In terms of cost, we didn’t need to use a microcatheter, saving time !!! 🩺🥼🩻🫀 @Dr. _BEEHARRY-Adil 👏🏻🤜🏼🤛🏼

By 2030 12.1 million people in the United States will have Atrial Fibrillation. Here's why this is a problem.   An arrhythmia can be any type of abnormal heart rhythm. Beating too fast, too slowly, or just irregularly. During Atrial fibrillation in particular, the heart's upper chambers beat chaotically and irregularly. Because of the irregular heart beat, Atrial Fibrillation can impact the ability to lead an active lifestyle and greatly increases a patient's risk of having a stroke. That's why it's the most common type of heart arrhythmia treated today.   Cardiac ablation is one of the treatments for atrial fibrillation. During this treatment, a physician guides a catheter (thin hollow tube) through a blood vessel that leads into the heart. Then, depending on the method, heat, cold, energy pulses or other modalities are applied inside the heart to modify heart tissue and correct the irregular heartbeats.   Ablation requires precision. Targeting the affected tissues while minimizing damage to surrounding tissues and structures is critical.   The integration of NDI’s electromagnetic navigation technology into OEM applications enables physicians to increase the precision, safety and efficacy of cardiac ablation procedures.   Using special sensors embedded inside OEM tools, physicians can accurately and precisely guide those tools to a targeted treatment site and visualize real-time position and orientation of things like guidewires, tracking-enabled transseptal needles, and sensor-enabled catheters throughout procedures. https://lnkd.in/g5tkHcSW #Cardiology #MedicalDevices #MedTech

The Selected Terminology and General Principles of Ballooning (part 2) During balloon inflation, the dimensions of the waist must be determined and a decision made whether or not to fully inflate the balloon,what is it necessary? If the balloon diameter is small compared to the lesion, only a subtle waist is produced and the dilating force is small,although the dilating force can be increased by increasing the inflation pressure, but this puts the balloon at risk for rupture. Now think If the balloon diameter is large compared to the stenosis, while begin to inflate the balloon,rapidly a tight waist will be created but because the dilating force ,too,will be large, the adjacent normal vessel is at greater risk of injury because the force transmitted to the full balloon diameter and length. Visualizing the waist and reacting appropriately is one of the most important skills in interventional cardiology,as a general rule, if the waist is < 75% the diameter of the proximal and distal balloon, it is too tight; the balloon should not be fully inflated, and the dilation should be repeated with a smaller balloon. #cardiology #balloon #intervention

IVUS is a gamechanger in endovascular treatment of acute aortic dissection with malperfusion. Visualization of membran movement, identification of true and false lumen, origin of the visceral vessels, diameter measurement and treatment effect after entry closure is much easier than with transesophageal echocardiography. check out our new publication: 📰 Intravascular Ultrasound Enhances the PETTICOAT Technique in Endovascular Therapy for Complicated Type B Aortic Dissection with Malperfusion Syndrome https://lnkd.in/ehZ24CNm #IVUS #aortaed #aorticdissection #malperfusion Andreas Kyriakou

Interesting Case Study Highlight: Diagnosing Myositis Ossificans Clinical History: A 19-year-old male soccer player complaining of left thigh inner mass midsection with pain and stiffness. The patient had a history of thigh trauma 2 months ago during a football match. Diagnosis: Following thorough medical imaging examinations at ERAD, the diagnostic results indicated a case of Myositis Ossificans, a condition where bone tissue forms inside muscle or soft tissue after trauma. Early and accurate diagnosis was crucial in guiding his treatment plan, ensuring a swift recovery and a return to the field.
