|dc.description.abstract||The main results of the studies of Kopka et al () and Earls et al ( ) were that the signal-to-noise and contrast -to-noise ratios were higher by using a power injector. We do accept that the peak enhancement percentage and slope in a contrast-enhanced dynamic MR study could be slightly different by using different injection methods. However, in our study, the enhancement percentage and slope showed no significant difference between the compression fracture and metastatic groups. It is the enhancement pattern (type AE) and especially the second part of the curve after the rapidly rising first part that is helpful in differentiating between benign and malignant lesions. In our results, the type D pattern (the early washout phenomenon) had a 100% specificity for malignant lesions. There is no evidence that a power injector will change the tissue enhancement pattern in comparison with a manual bolus injection . between benign and malignant lesions.
