High kvp contrast
WebConclusions: Diagnostic CTPA with 17 ml contrast media is possible in non-obese patients using low kVp, high pitch and carefully designed contrast media administration. Advances in knowledge: By combining several procedures in a CTPA protocol, the contrast media dose can be minimized.

WebA choice of low kVp results in short-scale contrast having two steps – black and white. Choosing a high kVp creates films with a long-scale contrast of five steps – black, dark gray, medium gray, light gray, white. Optimum kVp for any body part produces an intermediate-scale contrast of four steps – black, dark gray, light gray, white.2 WebUnderstanding kVp & mAs (X-Ray Exposure Factors) Clover Learning 28K subscribers Subscribe 2.8K Share 161K views 3 years ago RadTechBootCamp Videos Visit www.radtechbootcamp.com today to view the...
