Quantitative Evaluation of the Performance of a New Test Bolus-Based Computed Tomographic Angiography Contrast-Enhancement-Prediction Algorithm
Popis výsledku v původním jazyce
Objectives: The objective of this study was to assess the robustness of a novel test bolus (TB)-based computed tomographic angiography (CTA) contrast-enhancement-prediction (CEP) algorithm by retrospectively quantifying the systematic and random errors between the predicted and true enhancements. Materials and Methods: All local institutional review boards approved this retrospective study, in which a total of 72 (3 x 24) anonymized cardiac CTA examinations were collected from 3 hospitals. All patients(46 men; median age, 62 years [range, 31-81 years]) underwent a TB scan and a cardiac CTA according to local scan and injection protocols. For each patient, a shorter TB signal and TB signals with lower temporal resolution were derived from the originalTB signal. The CEP algorithm predicted the enhancement in the descending aorta (DAo) on the basis of the TB signals in the DAo, the injection protocols and kilovolt settings, as well as population-averaged blood circulation characteristic
