3-D model imaging to treat irregular heartbeats in patients, advancement in Cardiovascular Therapy SRM Global Hospitals has introduced an X-ray free, 3-D model-based imaging system, to identify abnormal heart tissues that cause irregular heart rhythms before treating them using a catheter-based procedure, known as ablation. According to a press release, the hospital adopted the cardiac mapping system to treat a 57-year-old man who suffered from supraventricular tachycardia, a condition of faster than normal heartbeat. T.R. Muralidharan, director of Institute of Cardiac Sciences, SRM Global Hospitals and his team used the imaging system and performed an ablation, which is a minimally invasive procedure. The system was based on an advanced non-fluoroscopic mapping technology that avoids or minimises radiation exposure and provides detailed, three-dimensional models and maps that can help doctors effectively diagnose the sources of irregular heart rhythms, the release said. news credit- The Hindu photo credit- Google/SRM official

Pelvic venous disorders (PeVDs) are rarely considered as a cause of chronic pelvic pain in women being evaluated by nonvascular specialists. A Society of Interventional Radiology (SIR) Foundation-sponsored Research Consensus Panel addressing this issue identified multiple gaps in the literature and made recommendations to enhance the evidence. Since publication of these recommendations in 2019, significant progress has been made in developing the necessary tools to improve the ability to conduct rigorous clinical studies and advance the evidence supporting the diagnosis and treatment of PeVD. This report summarizes the 5-year impact of the panel's recommendations. The investment made by SIR Foundation to host a Research Consensus Panel on PeVD has facilitated enduring academic productivity related to this clinical issue. 10.1016/j.jvir.2024.09.010

🧠 🏥 Check out the following article from the American Journal of Neuroradiology, "Advances in Acute Ischemic Stroke Treatment: Current Status and Future Directions." This article discusses the significant progress in treating acute ischemic strokes, particularly with the emergence of endovascular thrombectomy (EVT) and advances in medical therapy, imaging, and other aspects of stroke care. It highlights the importance of staying updated on the latest stroke trials and their implications for future care. Recent trials have shown better outcomes with EVT in posterior circulation strokes (PCS) and larger strokes, which significantly impacts stroke care. It also emphasizes radiologists' crucial role in staying informed about these developments to influence patient outcomes positively. 👉 To read the full article, follow this link: https://bit.ly/3VcppIp #stroke #strokecare #radiology #health #healthcare #medical #medicalcare #patientsafety #patientcare

“Transcranial Sonography Used as a Valuable Diagnostic Tool for Detecting a Hemoventricle, in an Intensive Care Unit Patient,” by Drs. Issac Cheong, MD and Francisco Marcelo Tamagnone MD. https://lnkd.in/ebgxhKE6. In the current print issue of the Journal of Diagnostic Medical Ultrasound (May/June 2024) there is a nice case study report from two Argentinian doctors demonstrating an innovative use of POCUS TCD. You will learn about hemoventricles and why TCD (and ultrasound in general) is needed in the ICU. As the authors explain, “A hemoventricle is a rare and life-threatening condition, characterized by blood accumulating in the brain ventricles. Computed tomography (CT) is commonly used in the diagnosis of hemoventricle. However, the use of CT is limited in the intensive care unit. ... A case study is presented of a 64-year-old female patient with a ruptured aneurysm who underwent endovascular coiling and the placement of an external ventricular drain. Point-of-care ultrasonography revealed ventricular dilatation that was associated with hyperechoic content and that was consistent with hemoventricle.” Cheong and Tamagnone explain that a CT examination confirmed their diagnosis and conclude that, “This diagnostic process allowed for prompt surgical intervention, with the placement of an EVD. This case demonstrates that sonography of the brain can be considered a valuable diagnostic point-of-care tool and may be a first choice for diagnosing a hemoventricle that may have resulted from cerebral aneurysmal rupture.” Other controversies concerning possible treatment options and the limitations preventing an alternative use of MRI in the acute phase are discussed. These author clinicians have presented a very balanced and useful TCD POCUS report. #tcd #sonography #brain #hemoventricle #ultrasound #mri #ct #evd #pocus #hydrocephalus #hemorrhage

SPECTRAL CTA FOR BRAIN IMAGING Detectability of intracranial vessel wall atherosclerosis using black-blood spectral CT: a phantom and clinical study. Fan Zhang et al. Eur Radiol Exp. 2024 Jul 3;8(1):78. doi: 10.1186/s41747-024-00473-x. Objective The study assessed spectral black-blood (SBB) imaging from dual-layer spectral CT for detecting intracranial atherosclerosis, comparing it with conventional CT angiography (CTA) and high-resolution MRI (hrMRI). Methods 1. Phantom Study: • Tested SBB and conventional CTA on a model mimicking intracranial arteries. • Measured wall detectability, accuracy, and contrast-to-noise ratio (CNR). 2. Clinical Study: • Included 34 stroke patients undergoing SBB and hrMRI. • Evaluated diagnostic certainty, vessel conspicuity, and plaque detectability. Key Findings 1. Phantom Study: • SBB detected 100% of walls, including those <1 mm, vs. 75% with CTA. • SBB had greater accuracy for wall thickness (MAE 3% vs. 8% for CTA). 2. Clinical Study: • SBB improved plaque detection (sensitivity 94%, specificity 98%) compared to CTA (24%, 74%). • CNR for wall/lumen was higher with SBB than hrMRI (p < 0.001). • Morphological measurements (e.g., plaque burden) from SBB closely matched hrMRI. Conclusions • SBB significantly enhances intracranial plaque detection, offering hrMRI-like accuracy with faster acquisition and fewer motion artifacts. • It is a promising tool for stroke prevention and vascular assessments. Limitations • Small sample size. • Excluded calcified plaques. • Focused on posterior circulation only. This study highlights SBB’s potential as a cost-effective alternative to hrMRI for detecting intracranial atherosclerosis.

A 38-year-old patient presented with suspected normal findings on initial CT imaging. However, subtle but significant findings were noted: a hyperdense MCA sign, suggesting the presence of a fresh clot, along with a right insular ribbon sign. These signs raised the suspicion of an acute ischemic event, prompting further investigation. An hour later, the patient underwent a CTA (CT angiography), which confirmed MCA (Middle Cerebral Artery) occlusion. Key Learning Points: Hyperdense MCA Sign: The presence of a hyperdense MCA sign on CT is an indicator of a fresh clot within the MCA, even in the absence of overt symptoms. It is often seen in the acute phase of ischemic stroke. Right Insular Ribbon Sign: This sign, characterized by a subtle loss of gray-white matter differentiation in the insular region, can be an early indicator of ischemia. It can be seen before any obvious ischemic changes are evident in the brain. Importance of Follow-Up Imaging: This case highlights the necessity of prompt follow-up imaging, even when initial CT findings appear normal. CTA can provide critical confirmation of occlusion and guide timely interventions. Early Detection and Intervention: Recognizing these early radiologic signs is crucial for effective management of acute ischemic strokes and optimizing patient outcomes. #NeuroImaging #AcuteStroke #MCAOcclusion #CTAngiography #IschemicStroke #Radiology #MedicalEducation
