Comparison of rotational with conventional coronary angiography

American Heart Journal, 2010
Patient radiation exposure and consumption of contrast medium are considered major risks of diagnostic coronary angiography (CA). Rotation of the C-arm during CA could provide similar diagnostic accuracy and lower radiation exposure and contrast medium consumption.To compare feasibility, safety, diagnostic accuracy, patient radiation exposure, and ...

A subtraction technique in conventional angiography.

Radiology, 1984
A subtraction technique is described for conventional angiography by which a superimposed vessel can be removed, allowing exact visualization of the area in question. The method is easy, requires only standard subtraction apparatus, and obviates the need for additional contrast material injections.

Coarctation of the aorta: comparison of aortic dimensions between conventional MR imaging, 3D MR angiography, and conventional angiography

European Radiology, 2002
Magnetic resonance angiography is increasingly used as a non-invasive method in the evaluation of coarctation of the aorta. The aim of this study was to compare aortic dimensions calculated by MR angiography and those obtained by more conventional MR sequences and conventional angiography.

Digital subtraction cerebral angiography by intraarterial injection: comparison with conventional angiography

American Journal of Roentgenology, 1983
For 4 months, a prototype digital subtraction system was used to obtain images of the cerebral vasculature after intraarterial contrast injections. In 12 instances, the intraarterial injections were recorded with both a digital subtraction unit and conventional direct magnification film-screen system.

A comparison of magnetic resonance angiography with conventional angiography in the diagnosis of tetralogy of Fallot

Cardiology in the Young, 2006
Aims: Our purpose was to assess the value of magnetic resonance angiography as a non-invasive alternative to catheterization in the evaluation of patients with tetralogy of Fallot, including those with pulmonary atresia. Methods and results: We evaluated prospectively, using magnetic resonance angiography, 30 patients, aged from 1 to 18 years, 15 with ...

Comparative performance of magnetic resonance angiography and conventional angiography in moyamoya disease

Journal of Clinical Neuroscience, 2000
Patients with moyamoya disease verified by conventional cerebral angiography (CCA) were evaluated by means of magnetic resonance angiography (MRA), in order to clarify its advantages and limitations in comparison with CCA. This retrospective study was carried out in 13 hemispheres of seven patients with moyamoya disease (including one atypical patient).

Subtraction CT angiography for evaluation of intracranial aneurysms: comparison with conventional CT angiography

European Radiology, 2009
The purpose of our study was to compare the diagnostic performance of subtraction computed tomography angiography (CTA) with conventional nonsubtracted CTA and digital subtraction angiography (DSA) for the detection of intracranial aneurysms. A total of 76 patients underwent both subtraction CTA and conventional CTA for the detection and therapy ...

Intraarterial digital subtraction angiography vs conventional angiography of abdominal diseases

Computerized Radiology, 1985
Seventy-five patients with various abdominal diseases were studied by intraarterial digital subtraction angiography (IA DSA) during conventional abdominal angiographic examinations. The image quality, tumor stain, and arterial encasements were evaluated and diameters of vessels visualized by IA DSA were measured. The vessels greater than 2.0 mm or more
