Techniques in Vascular and Interventional Radiology, 2001
Angioscopy provides a magnified, real-time, 360-degree view of the endoluminal surface of blood vessels, yielding unique information that is often complementary to conventional angiography. This unique perspective can significantly enhance one's perception and appreciation of endovascular disease.

Coronary angioscopy evaluates the composition of the atherosclerotic plaque by direct examination of the arterial wall. The angioscope is fitted with a balloon which prevents assessment of the proximal segment of the vessels. The fibre optic system provides and excellent view of the mid and distal segments of the coronary arteries.

Nihon rinsho. Japanese journal of clinical medicine, 2012
Angiography currently is the principle diagnostic test for evaluation of the vasculature. Though this invasive radiologic procedure demonstrates vascular anatomy and areas of narrowing and blockage, it does not define the specific cause of the occlusion. This limitation may inhibit the appropriate treatment of vascular disease.

Angioscopy in vascular surgery
Cardiovascular Surgery, 1997The role of Intraoperative angioscopy continues to evolve. To better define the role of angioscopy in vascular surgery, a review of the recent literature was performed. The most well-established indication for angioscopy is preparation of the saphenous vein for in situ bypass; however, angioscopy has also been demonstrated to be useful in the ...

DIAGNOSTIC AND INTERVENTIONAL ANGIOSCOPY
Surgical Clinics of North America, 1998As an imaging modality, angioscopy provides a simple method for the careful evaluation and treatment of the lumen of native vessels and bypass grafts. When used as a diagnostic study, angioscopy can provide more accurate information regarding the flow surface than conventional tests, such as angiography or duplex imaging.

Color Angiography and Angioscopy
Ophthalmologica, 1975The authors present the results of their color fluorescein angiographies carried out with a pocket retinograph equipped with new interferential filters. After the graphic examination, they propose to use these same filters mounted on different instruments for binocular and monocular angioscopy. Their results show that retinal vessels are translucid and

Percutaneous angioscopy: Improved technique
Cardiovascular and Interventional Radiology, 1993Ten angioscopies with a pressure infusion set resulted in similar visualization times and irrigation volumes as 42 angioscopies with a specially constructed roller pump. Diagnostic image quality, however, was obtained almost exclusively with the roller pump. Three examinations were nondiagnostic.

Improved Method of Fluorescein Angioscopy
Archives of Ophthalmology, 1990To the Editor. —The technique of fluorescein angioscopy has been used by ophthalmologists to supplement ophthalmoscopy in the diagnosis of retinal diseases. 1,2 The usual technique consists of the intravenous injection of fluorescein sodium following placement of a cobalt blue filter over the illumination source of the indirect ophthalmoscope.

Quantitative Endovascular Angioscopy
SPIE Proceedings, 1989Currently there is no available system capable of providing real-time absolute dimensional analysis of features within the field of view of conventional angioscopes. This paper describes a method which utilizes computer-based image processing equipment and novel algorithms to address this problem.

Since 1987, routine angioscopic examination has been performed in 191 patients undergoing angioplasty, with interventions (196) after a 2 year surveillance period (55). Angioscopy allowed follow up "de visu" of the performance of angioplasty, details of its mechanism to be precise and under dilatation to be carried out. For femoral artery occlusions it
