Abstract:
The objective of this study is to evaluate the image quality with two different contrast agents in MRCP compared to medical evaluation and by using the software Image J®. Natural juices and pulps of different types (açai liquid and powder; and blend) were selected. The selection of patients (31 women and 33 men) was performed at Clinical Hospital, which provides general care in Curitiba city (Brazil). The application of the MRCP protocol followed a sequence tested in healthy volunteers and for the samples described. For image analysis, 2 radiologists participated and were identified as evaluator 1 (E1) and 2 (E2), in order to identify the effect of the contrasts on the images. For the 6 samples tested, only 2 samples remained dark on T2 weighting, which prevents their use as contrast agent. The evaluation of the images was performed separately for each evaluator on different days and places, to identify an appropriate action for the contrasts (A and B). The use of the software (Image
J®) allowed a less subjective analysis of the image quality when compared to the evaluation of radiologists and, for the examples presented, a quantitative assessment since the chosen images were submitted to the software analysis.
