What is Neurovascular Imaging Neurovascular imaging plays a crucial role in the diagnosis, characterization, and treatment planning of the conditions faced by patients. Dr. Santosh B. Patil offers a comprehensive suite of advanced imaging modalities to provide precise and detailed assessments of neurovascular anatomy, facilitating optimal patient care and treatment outcomes. Symptoms Symptoms related to neurovascular issues can vary widely depending on the specific condition, but here are some general symptoms that might prompt a need for neurovascular imaging: Headaches Sudden or gradual changes in vision, including blurriness, double vision, or loss of vision Weakness or numbness Speech difficulties Balance and coordination problems Memory problems or confusion We offers a comprehensive suite of advanced imaging modalities to provide precise and detailed assessments of neurovascular anatomy TREATMENT Catheter Angiography Digital subtraction angiography (DSA) is considered the gold standard for evaluating vascular anatomy and pathology within the brain and spinal cord. Dr. Patil utilizes DSA to: High-Resolution Imaging: DSA provides high-resolution images of blood vessels, allowing for precise visualization of vascular lesions such as aneurysms, arteriovenous malformations (AVMs), and stenoses. Dynamic Assessment: DSA enables dynamic assessment of blood flow dynamics, including the detection of vascular abnormalities such as fistulas and hemodynamic changes associated with ischemic or hemorrhagic stroke. TREATMENT Magnetic Resonance Angiography (MRA) Magnetic resonance angiography (MRA) is a non-invasive imaging technique that utilizes magnetic resonance imaging (MRI) technology to visualize blood vessels within the brain and neck. Dr. Patil employs MRA to: Non-Invasive Assessment: MRA allows for non-invasive assessment of vascular anatomy, providing detailed images of arteries and veins without the need for contrast agents or radiation exposure. Multiplanar Imaging: MRA offers multiplanar imaging capabilities, enabling visualization of blood vessels from various angles and perspectives, enhancing diagnostic accuracy and treatment planning. TREATMENT Computed Tomography Angiography (CTA) Computed tomography angiography (CTA) combines computed tomography (CT) scanning with contrast enhancement to produce detailed images of the blood vessels. Dr. Patil utilizes CTA to: High-Resolution Imaging: CTA provides high-resolution images of vascular structures, allowing for the detection and characterization of vascular lesions such as aneurysms, dissections, and thrombi. Rapid Acquisition: CTA offers rapid acquisition times, making it well-suited for emergent evaluation of acute cerebrovascular conditions such as ischemic stroke or intracranial hemorrhage. TREATMENT Perfusion Imaging Perfusion imaging techniques, such as CT perfusion and MR perfusion, provide valuable information about cerebral blood flow and tissue perfusion. Dr. Patil utilizes perfusion imaging to: Assess Tissue Viability: Perfusion imaging assesses tissue perfusion and oxygenation, helping to identify areas of hypoperfusion or ischemia in acute stroke patients and guide treatment decisions. Evaluate Treatment Response: Perfusion imaging can also be used to evaluate treatment response following interventions such as thrombolysis or endovascular thrombectomy, providing insights into tissue reperfusion and functional recovery. TREATMENT Carotid Doppler Ultrasound Carotid Doppler ultrasound is a non-invasive imaging technique used to assess blood flow in the carotid arteries. Dr. Patil employs carotid Doppler ultrasound to: Detect Stenosis: Carotid Doppler ultrasound detects and quantifies the degree of stenosis in the carotid arteries, providing valuable information for risk stratification and treatment planning in patients with carotid artery disease. Carotid Doppler ultrasound can also be used to monitor disease progression over time, allowing for early detection of changes in carotid artery patency and the initiation of appropriate interventions FAQ'S Frequently Asked Questions What is neurovascular imaging, and why is it important? What is the difference between catheter angiography (DSA) and other neurovascular imaging modalities like MRI or CT scans? When is neurovascular imaging typically recommended for patients? What are the benefits of perfusion imaging in the evaluation of stroke patients? What can carotid Doppler ultrasound reveal about vascular health? Are there any risks or limitations associated with neurovascular imaging procedures? While neurovascular imaging procedures are generally safe, there are potential risks such as allergic reactions to contrast dye, exposure to radiation in CT scans, or complications related to catheter angiography, such as bleeding or blood vessel injury. However, the benefits of obtaining crucial diagnostic information often outweigh these risks, especially when performed by experienced spec
