Shimadzu Review 76[3・4] (2020.1)


One problem with using an angiography system for lower extremity endovascular treatment (EVT) is that the generally long lesion areas require more exposures, which results in higher patient exposure dose and contrast media usage levels. Therefore, Shimadzu has developed the SCORE Chase application for supporting lower extremity EVT procedures by reducing the X-ray exposure dose and contrast media levels used for patients without changing the EVT process   workflow. 

Features of the application are described below. 

  1. SCORE Chase automatically generates long-view images by freely moving the table longitudinally or transversely to acquire a series of images along the blood vessel travel path in the lower extremities and then immediately reconstructing the images.
  2. By reusing previous contrast tracking images, additional vessel road maps can be generated multiple times without using any additional contrast media.
