Comparative Study Controlled Clinical Trial
[First experiences with intravenous port systems authorized for high pressure injection of contrast agent in multiphasic computed tomography].
The aim of this prospective study was to examine two port systems for intravenous chemotherapy, authorized for high pressure injection, with respect to implantation, complications, implementation, and patency. ⋯ The intravenous high pressure port systems are equivalent to standard systems with regard to implantation and implementation. Intravenous chemotherapy can be performed as usual. The advantage is the possibility of multiphasic CT with authorized flow rates of up to 5 ml/sec.

Microvascular obstruction (MO) and the extent of infarction are important prognostic factors in acute myocardial infarction. Our study aimed to investigate the effect of the time interval between contrast administration and image acquisition on the quantification of microvascular obstruction and myocardial infarction. ⋯ Our study shows that the time delay between contrast media injection and image acquisition has a significant impact on the delimitable extent of MO and infarct size.
