REAL‐TIME IMAGE QUALITY ENHANCEMENT WITH KINETIC IMAGING IN CARBON‐DIOXIDE ANGIOGRAPHY

ESVS 32nd Annual Meeting, Valencia, Spain, 24-28 September, 2018
Viktor I. Orias, Marcell Gyano, David Szollosi, Istvan Gog, Krisztian Szigeti, Szabolcs Osvath, B...

We can conclude that kinetic imaging provides significant image quality enhancement in CO2A. The better image quality potentiates the making of adequate diagnosis. The adjustment of gas injection parameters could eliminate further disadvantages of the technique and dynamic information could also ...

EVALUATION OF KINETIC IMAGING IN CAROTID AND CEREBRAL X-RAY ANGIOGRAPHY

ESVS 32nd Annual Meeting, Valencia, Spain, 24-28 September, 2018

Real-time image quality enhancement with kinetic imaging in carbon-dioxide angiography

CIRSE, Lisbon, Portugal, 09.22.2018-09.25.2018
V. Óriás, M. Gyánó, D. Szöllősi, I. Góg, Z. Ruzsa, B. Nemes, K. Szigeti, S. Osváth, P. Sótonyi

Carbon‑dioxide angiography (CO2A) is a decades‑old invasive diagnostic technique preferred in patients suffering from renal failure or iodine allergy. Widespread usage of the technique is mainly held up by the fact that digital subtraction angiography (DSA) images provide remarkably lower image q...

75% X-ray dose reduction in angiography - comparing kinetic imaging with conventional DSA

CIRSE, Lisbon, Portugal, 09.22.2018-09.25.2018
M. Gyano, B. Nemes, D. Veres, D. Szöllősi, S. Osváth, K. Szigeti, P. Sótonyi

Kinetic imaging (KI) analyses pixel-intensity variations of an X-ray image series. Earlier findings indicate that KI of X-ray angiograms provide identical information to DSA, but with better signal to noise ratio. Therefore, using KI, the usual quality of DSA images becomes available at a lower x...
