In relation to being an EKG Technician, having an EKG Technician job or even attending to an EKG Technician Classes, dynamic contrast-enhanced MR imaging can potentially improve the diagnostic yield. Data provided reflects capillary blood flow, permeability, and the relative volume of extravascular and extracellular space, resulting in quantitative parameters related to tumor angiogenesis.
Two quantitative parameters have been demonstrated to improve relapse detection in several areas of the body: the slope of enhancement over 60 seconds, which is related to tissue vascularization for example, the number of vessels, the degree of perfusion, and capillary permeability; and the maximum average enhancement which is dependent on the volume of the extra – cellular space. In the follow-up after surgery and/or radiotherapy of 27 head and neck and skull base tumors, we recently observed that the slope of enhancement and maximum intensity averages of recurrences were significantly steeper and higher, respectively, than in negative lesions.
