Angiography

These strategies simply target at a model of care for treating DR based on diagnosis rather than an opportunity for preventative eye care and health promotion. Fundus photography, ophthalmoscopy, and fluorescein angiography are the typical tools to diagnose DR and diabetic macular edema [38, 39]. Nonetheless, a widespread range of potential solutions, such as, eyewear innovations, functional tests, groundbreaking eye care treatment, new imaging devices, vision training

Magnetic Resonance Angiography (MRA) is a technique in which magnetic pulses are used to image pictures of blood vessels inside the body. A MRA can be achieved using two techniques phase contrast and time of flight. A phase contrast can be done using complex subtraction and phase subtraction. A time of flight (TOF) can be done using dark blood and bright blood. A dark blood imaging is visualized using inversion recovery, saturation and dephasing. A bright blood imaging is analyzed using rephased

Coronary CT angiography on revascularized patients: coronary stenting Recently, coronary CT angiography has been increasingly used for assessment of coronary stent patency or restenosis. However, imaging of coronary stents by multislice CT is more difficult than imaging of a native coronary artery. This is because of the presence of metal within the stents which can cause artifacts interfering with the interpretation of lumen patency. While the accuracy of stent lumen analysis was low or modest with

The maintenance of low heart rates is preferable when conducting coronary CT angiography (CCTA). Current medical publications recommend a heart rate less than 60 beats/min for optimal image and radiation dose reduction. Patients undergoing CCTA are usually given beta-blockers if there are no contraindications one hour before the test to control the heart rate. Another method that is used in moderating the heart rate of patients undergoing CCTA is ivabradine. Ivabradine is a novel heart rate-reducing

may prevent a stroke or a heart attack. CT coronary angiogram which is imaging the vessels that supply heart with blood is now widely used instead of invasive coronary angiography to diagnose coronary heart disease because it seems to be more efficient 1.For high-risk population, the use of high definition CT coronary angiography and an experienced readers result in better diagnosis compared to traditional coronary angiography2 Radiation is used in both traditional and CT angiogram but CT angiogram

The Diagnostic value of Dual-Source Computed Tomography Coronary Angiography (DSCT-CA) for the Diagnosis of Coronary Artery Disease in the Intermediate Risk Group in relation to Conventional Angiography: Literature Review Abstract Background: Coronary artery disease (CAD) is the leading cause of death in developed countries. Conventional coronary angiography is considered as the ‘‘gold standard’’ for the diagnosis of CAD, but it is invasive and carries risks of vascular complications

fluoroscopy nor echocardiography can adequately depict this anatomy. Earlier reports have shown that 3D gadolinium-enhanced magnetic resonance (MR) angiography can successfully demonstrate left atrial and distal pulmonary venous anatomy (1–4); however, many atrial fibrillation patients have pacemakers or defibrillators and cannot undergo MR angiography. Initially, we developed a 3D multi–detector row computed tomographic (CT) technique to image the left atrium and pulmonary veins in patients with

A coronary artery anomaly (CAA) is defined as a congenital coronary artery malformation in the absence of other congenital cardiac defects. As we continue to lack a screening tool to diagnose CAAs, catheter-directed angiography remains the gold standard both for diagnosis and treatment of CAAs. Intervening CAAs continues to remain a complicated task even in the hands of experienced operators. The greatest challenged faced in the management of CAAs is a delay in recognition largely due to the element

MRI. Electrocardiography. This is a test that records the electrical impulses of the heart. Angiography. This is a test that produces images of arteries in your body. You may need aortic angiography or CT angiography. In aortic angiography, a dye flows to your heart through a soft, flexible tube (catheter) while X-rays are taken. CT angiography uses a CT scanner and MRI in addition to the catheter, dye, and X-rays. How is this treated? Treatment depends on how severe
