A new approach to measuring tortuosity
SPIE Proceedings, 2012The detection and measurement of the tortuosity - i.e. the bending and winding - of vessels has been shown to be potentially useful in the assessment of cancer progression and treatment response. Although several metrics for tortuosity are used, no single one measure is able to capture all types of tortuosity.

Congenital Tortuosity of the Retinal Arteries
Archives of Ophthalmology, 1977A 65-year-old woman who had no ocular complaints was examined and was found to have tortuous arteries in both posterior poles of the fundus. Visual acuity was 20/20 in each eye, and the results of the remainder of the ocular examination were normal. There were no significant systemic abnormalities.

Tortuosity of the human splenic artery
Clinical Anatomy, 1995AbstractArantius (1571) was the first to describe tortuosity of the splenic artery. The present study investigated the variations in its tortuosity in man, and possible relationships with age, sex, and presence of atheroma.Twenty‐nine cadaveric specimens and forty‐four celiac angiograms were studied. The straight distance from the origin of the splenic

Improved characterisation of aortic tortuosity
Medical Engineering & Physics, 2011Tortuosity can be described as the variation in blood vessel curvature. Abnormal tortuosity is an important clinical indicator of various conditions. Despite considerable research, there has been very little agreement on an accurate, unique measure of this phenomenon for clinical applications.

Tortuosity of Subclavian And Innominate Arteries
JAMA: The Journal of the American Medical Association, 1968To the Editor:— As Bousvaros and Sandler report ( 205 :466, 1968), tortuosity of the subclavian and innominate arteries is commonly encountered in catheterization of the thoracic aorta. Prolonged manipulation in order to pass a catheter beyond this area is undesirable and may lead to intimal dissection.
