modalities for the evaluation of arterial vessels have been introduced. These include Color Doppler Ultrasound (CDU), spiral Computed Tomography (CT) and Magnetic Resonance [1-5]. The non-invasive character of these techniques represents a major advantage when compared with intra-arterial Digital Subtraction Angiography (DSA). These techniques are redefining the goals of DSA or “catheter based”...

BACKGROUND To determine the utility of digital subtraction angiography (DSA) in patients with unruptured intracranial aneurysms (UIA) detected on noninvasive imaging, such as magnetic resonance angiography (MRA) and computed tomography angiography (CTA). The follow-up of patients with untreated UIAs involves serial imaging; however, this diagnosis may be based on false positive (FP) results. We...

Arterial vascular variation of the head and neck is common and is often overlooked because of the lack of obvious clinical symptoms. Variations are generally detected accidentally by head and neck computed tomography angiography (CTA), magnetic resonance angiography (MRA) or ultrasound. Considering the lack of adequate understanding of the presence and location of the arterial vascular variatio...

Diagnostic Catheter Procedures In 1958, Mason Sones and his colleagues developed selective coronary angiography and published it as an abstract in Circulation.2 As a cardiologist at the Cleveland Clinic, he performed angiography of the aortic root in a patient with valvular heart disease. Looking directly into the x-ray beam, as was customary in the era before image intensifiers coupled to tele...

Vascular diseases are nowadays one of the serious issues which have a huge impact on someone's life. Number of researchers at different universities as well as medical device manufacturers are working in this field for better understanding of the vascular characteristics. It is expected that three dimensional structure of blood vessels can provide comprehensive visualization of vessel geometry....

Fluorescein A ngiography in Microvascular Surgery: A Sniily ' Using the Rodent Artery • Fluorescein angiography was carried out on 45 Ostpon Mendelson rats with a view toward detecting injury areas following microvascular anastomoses. Decreased fluorescence was seen regardless if the injury occurred prior to or after the injection of fluorescein, and also if postinjury angiography was filmed du...

OBJECTIVES We sought to determine the diagnostic performance of whole-heart coronary magnetic resonance (MR) angiography for detecting significant coronary artery disease. BACKGROUND The accuracy of whole-heart coronary MR angiography has not been determined in a large number of patients. METHODS Three-dimensional coronary MR angiograms covering the entire heart were obtained during free br...

X-ray angiography is the gold standard in assessing coronary artery diseases. With research focus shifting towards 3D+t applications, heart models that allow for the extraction of functional parameters from the heart motion receive increasing attention. We present an approach to fit a parametric left ventricular heart model originally developed for tagged MRI to the centerlines of coronary arte...

Coronary artery aneurysm is an uncommon disease. We present a case of an unusual huge saccular coronary aneurysm of the left anterior descending coronary artery detected by 64-slice multi-detector computed tomography (MDCT) coronary angiography, which initially presented as a mediastinal mass on chest X-ray. The true size of the aneurysm would have been underestimated by coronary angiography be...

OBJECTIVE To assess the importance of genetic background for collateral artery development. METHODS AND RESULTS C57BL/6, BALB/c and 129S2/Sv mice were studied after femoral artery ligation by laser Doppler imaging, visible light oximetry, time-of-flight-magnetic resonance imaging, and treadmill testing; C57BL/6 and BALB/c also underwent electron paramagnetic resonance (EPR) oximetry, x-ray an...
