Continuum of vasodilator stress from rest to contrast medium to adenosine hyperemia for fractional flow reserve assessment [PDF]
JACC: Cardiovascular Interventions, 2016 Objectives: This study compared the diagnostic performance with adenosine-derived fractional flow reserve (FFR) ≤0.8 of contrast-based FFR (cFFR), resting distal pressure (Pd)/aortic pressure (Pa), and the instantaneous wave-free ratio (iFR ...

Asymptomatic contrast medium extravasation [PDF]
BMJ Case Reports, 2017 A 72-year-old man was referred for a contrast-enhanced multidetector coronary CT examination. A physician tried to place an angiocatheter (BD Insyte Autoguard Winged, 20G, 1.1×25 mm) into the right median basilic vein; however, the vein could not be punctured correctly because it was difficult to detect owing to the tortuosity of the patient’s vascular

PORTOHEPATOGRAPHY WITH AN OILY CONTRAST MEDIUM [PDF]
American Journal of Roentgenology, 1971 Splenoportography was performed in 38 patients, mainly with malignant tumors and metastases, using an oily contrast medium (lipiodol U.F.). The injection was well tolerated in all cases. Visualization of the intrahepatic branches of the portal vein was much clearer than that obtained with a water-soluble medium, and the hepatograms, in particular, were

Effect of delayed acquisition times on Gadolinium-enhanced MRI of the presumably normal canine brain [PDF]
, 2011 A delay in imaging following intravenous contrast medium administration has been recommended to reduce misdiagnoses. However, the normal variation of contrast enhancement in dogs following a delay has not been characterized.

Choice of contrast medium in sialography [PDF]
Oral Surgery, Oral Medicine, Oral Pathology, 1984 Contrast media used for sialography were originally developed for other medical applications. Therefore, it was considered desirable to investigate the properties of these substances for use in sialography. Eleven radiopaque substances were selected, and their properties for sialography were studied.

Contrast medium-induced nephropathy: The pathophysiology [PDF]
Kidney International, 2006 A widespread, rather general, definition of contrast-induced nephropathy (CIN) is an impairment in renal function occurring within 3 days following the intravascular administration of contrast media (CM) and the absence of an alternative aetiology. In spite of the vast clinical importance of CIN, its understanding and the pathophysiology behind CIN ...

Pathophysiology of contrast medium–induced nephropathy [PDF]
Kidney International, 2005 Contrast medium-induced nephropathy (CIN) is a well-known cause of acute renal failure, but the development of CIN remains poorly understood. A number of studies have been performed with the one aim, to shed some light onto the pathophysiology of CIN.

Effective Dielectric Tensor for Electromagnetic Wave Propagation in Random Media
, 2007 We derive exact strong-contrast expansions for the effective dielectric tensor $\epeff$ of electromagnetic waves propagating in a two-phase composite random medium with isotropic components explicitly in terms of certain integrals over the $n$-point ...
