BACKGROUND There is a high incidence of anomalous coronary arteries in subjects with congenital heart disease. These abnormalities can be responsible for myocardial ischemia and sudden death or be damaged during surgical intervention. It can be difficult to define the proximal course of anomalous coronary arteries with the use of conventional x-ray coronary angiography. Magnetic resonance coron...

Despite progress in prevention and early diagnosis, coronary artery disease (CAD) remains one of the leading causes of mortality in the world. For many years, invasive X-ray coronary angiography has been the method of choice for the diagnosis of significant CAD. However, up to 40% of patients referred for elective X-ray coronary angiography have no clinically significant stenoses. These patient...

Although conventional or digital X-ray angiography is still the standard method in the diagnosis of intracranial vascular abnormalities, MR imaging is gaining a more prominent role in this respect. MR angiography is a new method of vascular imaging that provides projection images resembling conventional angiography [1 , 2]. We present the MR angiographic findings in two patients with primitive ...

X-ray coronary angiography is an invaluable tool for the diagnosis of coronary artery disease. However, the use of iodine-based contrast media can be contraindicated for patients who present with chronic renal insufficiency or with severe iodine allergy. These patients could benefit from a reduced contrast agent concentration, possibly achieved through application of a mono-energetic x-ray beam...

The standard method of diagnosing and evaluating carotid—cavernous fistulas has been x-ray cerebral angiography using contrast media (1—9).However, improvements in nuclear medicine techniques in recent years have provided the ability to perform radionuclide cerebral angiography with a high de gree of accuracy (10—15). It is a benign procedure that does not require catheterization or radio...

Coronary angiography is the current gold standard for the diagnosis of ischemic heart disease and therefore the prevalence of percutaneous coronary procedures such as angiography and angioplasty is high. The occurrence of cerebral complications after coronary angiography and coronary angioplasty is low and it mainly includes transient ischemic attack and stroke. The prevalence of transient cort...

Objective: Coronary heart disease (CHD) is one of the most common diseases. Coronary angiography (CAG) is an important apparatus used to diagnose and treat this disease. Since angiography is performed through exposure to ionizing radiation, it can cause harmful effects induced by double-stranded breaks in DNA which is potentially life-threatening damage. The aim of the present study is to inves...

X-ray angiography using a contrast agent has the main advantage of being able to simultaneously demonstrate the anatomy of vessels and changes in morphology. In rats, morphological changes and different vasoreactivities have been studied by angiography; however, the spatial resolution has not been sufficient to detect detailed changes in vessel diameter. Furthermore, owing to the relatively lar...
