iohexol has been researched along with Coronary Stenosis in 41 studies
Iohexol: An effective non-ionic, water-soluble contrast agent which is used in myelography, arthrography, nephroangiography, arteriography, and other radiographic procedures. Its low systemic toxicity is the combined result of low chemotoxicity and low osmolality.
iohexol : A benzenedicarboxamide compound having N-(2,3-dihydroxypropyl)carbamoyl groups at the 1- and 3-positions, iodo substituents at the 2-, 4- and 6-positions and an N-(2,3-dihydroxypropyl)acetamido group at the 5-position.
Coronary Stenosis: Narrowing or constriction of a coronary artery.

The primary statistical measure will be the area under the receiver operating characteristic curve (AUC of ROC) of a patient-based model to detect hemodynamically significant obstruction. ROC graphs the change in sensitivity as the cut-point for positive/negative diagnosis moves from its lower to upper limit. FFR is used as the reference standard to determine the presence or absence of hemodynamic obstruction. For FFR, hemodynamically-significant obstruction of a coronary artery is defined as an FFR≤0.80 in any major epicardial coronary artery segment with diameter ≥2.0 mm during adenosine-mediated hyperemia. For cCTA, hemodynamically-significant obstruction of a coronary artery is defined as a stenosis >50% . FFRCT will be calculated for each patient as the minimum FFRCT in any coronary artery segment . cCTA stenosis will be calculated for each patient as the highest cCTA stenosis category for any vessel all measurements will take place only in segments with diameter ≥2.0 mm. (NCT01757678)
