Cardiac ultrasonography, commonly referred to as echocardiography, is the ultrasound imaging of the heart, an extremely complex and rapidly moving organ located deep within the body. A team of engineers and doctors in Trondheim have worked together on enhancing the techniques for imaging and analyzing the function of the heart for more than 30 years. The resolution of heart problems necessitates a relatively precise representation of everything that moves (cardiac muscles, valves, blood) within the heart. Therefore technology affects image analysis a lot. Therefore, there is a need for a variety of specific ultrasound modes and apps for doctors to perform this kind of study.
The prevalence of heart illness is rising, which supports the significance of cardiac assessment. Conventional examination and auscultation methods may not provide the level of sensitivity needed to detect some disorders. The discipline has substantially benefited from the development of cardiac ultrasonography (echocardiography) techniques. In addition to serving as a tool for diagnosis, ultrasound images also make it possible to develop treatment options and easily track the disease’s course.
Tissue Doppler Imaging
The first commercially viable option for measuring cardiac muscle strains was made possible by cardiac ultrasonography scanners in the 1990s. This discovery was made possible by significant contributions from the Trondheim ultrasonic technology research group. This early device calculated strain based on the spatial velocity gradients and approximated velocities using Doppler-related techniques. The left ventricle’s function has been quantified in great detail, but this approach was constrained because it could only estimate velocities and stresses based on the ultrasound beam. Unfortunately, “out-of-plane” motion and “out-of-beam-direction” mobility were major limitations.
Tissue Doppler
Tissue Doppler can be substituted with a technique called speckle tracking, which is also referred to as block matching or 2D strain. This method focuses on the movement of different structures in the ultrasound image frame by frame. The “speckles” in the images that move collectively inside the underlying structures do this. Speckle training depends on image analysis of gray-scale ultrasound recordings, whereas Doppler methods use a unique specific acquisition and processing.
3D Strain
Due to the limits of Doppler and speckle tracking, the ultrasound research community has been experimenting with 3D strain, also known as 4D strain. “Out-of-plane” motion is still challenging even if speckle tracking on 2D gray-scale photos produces 2D motion estimates. On 3D datasets, researchers are still investigating 3D block matching and related techniques.
Ultrasounds in Cardiology
Ultrasound Of The Abdominal Aorta
Blood from the heart travels through the aorta to the rest of your body. An abdominal aortic aneurysm can be brought on by high blood pressure, hardened arteries, trauma, and other conditions. This happens when the aorta enlarges, resulting in severe back or abdominal pain. Abdominal aorta ultrasounds find blockages and aneurysms in the aorta close to the diaphragm. After that, your doctor will decide how to stop your aneurysm from rupturing. Additionally, based on the size of the aneurysm, they might advise surgery.
Arterial Ultrasound
The sonographer looks at the arteries in the arms and legs using ultrasound imaging. The purpose is to observe the speed of blood flow and find blockages in the arteries, if any. These ultrasounds can also determine areas where arteries are contracting. If there is any damage or blood clot in your veins, the doctor will determine your condition and identify the best treatment method to prevent any more damage.
Carotid Ultrasound
Carotid arteries are located on the sides of your neck or head. The arteries are to pump blood to the brain. Carotid artery disease occurs when plaque blocks the arteries. It leads to a risk of suffering a stroke. It may occur at a smaller scale stroke known as a transient ischemic attack (TIA). A stroke is also possible when a blocked blood vessel may prevent blood flow to the brain. With the carotid duplex ultrasound, the doctor can see blockages in these arteries and assess a treatment plan immediately.
Echocardiogram
The ultrasound waves help the doctors see an image of the patient’s heart. It helps make any structural abnormalities prominent in its beating pattern. The size of one’s heart usually correlates with the body size, while there can be some differentiation. For instance, a thickened and enlarged heart might indicate hypertrophy. Through ultrasound imaging, cardiologists can more quickly assess the damage.
Renal Artery Ultrasound
The function of renal arteries is to supply oxygen and blood from the aorta to the kidneys. When there is a blockage or constriction in this flow, the kidneys fail to receive the important nutrients for healthy function. This ultrasound uses Doppler technology to look through several thicknesses of the tissue. It allows your doctor to see the signs of renal artery stenosis if any, or obstruction of the kidneys preventing proper waste removal. Moreover, if the renal artery is narrow, the patient is at a high risk of blood pressure or kidney failure. With proper imaging, patients are able to assess the correct level of preventive measures or medical intervention required to save their kidney health.
Venous Ultrasound
Venous ultrasound is used in cardiology to see how easily the blood flows through the veins. The sonographer might observe any signs of blood clots and the direction of blood flow. The ultrasound is especially effective in diagnosing deep vein thrombosis (DVT) and taking preventative steps against pulmonary embolism. You can distinguish damaged valves through venous ultrasound for patients with varicose veins.
Cardiac images are created using various techniques; some are invasive, but most are not. Transthoracic ultrasound is non-invasive. It allows for better imaging of all cardiac structures. Some parts, like aortic and mitral valve function, can be seen as best by transesophageal echocardiography, which is a more invasive method. Each window or modality is more sensitive to some specific cardiac structures compared to others.
Conclusion
Cardiovascular diseases are the top cause of death around the globe. Recently, cardiac ultrasound imaging has gone through technological advancements to aid the clinical diagnosis of many cardiovascular diseases. The benefits of ultrasound imaging include imaging at the patient’s bedside, real-time images, ionizing-radiation-free imaging, and cost-effectiveness. In addition to these benefits, the steps taken towards standardization of ultrasound-based quantitative markers play a crucial role in addressing the healthcare burden related to cardiovascular diseases.
