Evaluation of individually body weight adapted contrast media injection in coronary CT-angiography
Popis výsledku v původním jazyce
Objectives: Contrast media (CM) injection protocols should be customized to the individual patient. Aim of this study was to determine if software tailored CM injections result in diagnostic enhancement of the coronary arteries in computed tomography angiography (CTA) and if attenuation values were comparable between different weight categories. Materials and methods: 265 consecutive patients referred for routine coronary CTA were scanned on a 2nd generation dual-source CT. Group 1 (n = 141) received an individual CM bolus based on weight categories (39-59 kg; 60-74 kg; 75-94 kg; 95-109 kg) and scan duration ('high-pitch: 1 s; "dual-step prospective triggering": 7 s), as determined by contrast injection software (Certegra (TM) P3T, Bayer, Berlin, Germany). Group 2 (n = 124) received a standard fixed CM bolus; Iopromide 300mgI/m1; volume: 75 ml; flow rate: 7.2 ml/s. Contrast enhancement was measured in all proximal and distal coronary segments. Subjective and objective image quality was evaluated.
