Introduction<br />Atherosclerosis is considered one of the most dangerous cardiovascular diseases, where fats and cholesterol accumulate within the arterial walls, leading to narrowing and loss of elasticity. With advances in science, medical physics has come to play a crucial role in the accurate and advanced diagnosis and treatment of this disease.<br /><br />The Role of Medical Physics in Diagnosis<br />Medical physics contributes significantly to the development of imaging devices and technologies that help detect atherosclerosis at early stages. Among the most important diagnostic tools are:<br /><br />✅ Doppler Ultrasound<br />• Measures blood flow velocity and evaluates the degree of blockage or narrowing.<br />• Accurately determines the location of the atherosclerotic lesion without surgical intervention.<br /><br />✅ Magnetic Resonance Imaging (MRI)<br />• Provides a clear view of arterial walls and assesses their thickness.<br />• Uses magnetic contrast to differentiate between healthy tissue and plaques.<br /><br />✅ CT Angiography<br />• Offers detailed imaging of plaque buildup inside arteries.<br />• Measures the degree of narrowing and the size of the atherosclerosis.<br /><br />✅ Nuclear Cardiology<br />• Uses radioactive isotopes to evaluate blood flow through the coronary arteries.<br /><br />Therapeutic Interventions Using Medical Physics<br />The role of medical physics is not limited to diagnosis; it also includes advanced interventional treatments such as:<br /><br />✅ Interventional Catheterization and Stenting<br />• Uses X-ray guidance (fluoroscopy) to widen the artery with a small balloon and place a metal stent to keep it open.<br /><br />✅ Laser Angioplasty<br />• Uses laser beams to remove plaque and atherosclerotic buildup.<br /><br />✅ Intravascular Ultrasound (IVUS)<br />• A high-resolution imaging technique that guides the physician during intervention to locate the lesion and assess the effectiveness of dilation.<br /><br />✅ Brachytherapy (Localized Radiation Therapy)<br />• In certain cases, used to prevent re-narrowing of arteries after stent placement, by placing radioactive sources inside the artery for a limited time to reduce cell proliferation.<br /><br />Clinical Benefits of Medical Physics Techniques<br />• Facilitates early diagnosis and reduces complications.<br />• Precisely determines the severity of the disease for optimal treatment planning.<br />• Enables minimally invasive procedures, shortening recovery time.<br />• Allows continuous monitoring of disease progression through periodic imaging.<br /><br />Conclusion<br />Medical physics has made a revolutionary impact in the treatment of atherosclerosis by combining advanced technology with medical science. It not only offers more accurate diagnosis but also provides safe and effective therapeutic options, enhancing recovery prospects and prolonging patients’ lives.<br /><br /><br /><br />"AL_mustaqbal University is the first university in Iraq"<br/><br/><a href=https://uomus.edu.iq/Default.aspx target=_blank>al-mustaqbal University Website</a>
