Abstract
We succeeded in observing the transformation behavior of SAP-Microsphere which had absorbed serum saline
or ionic contrast media (Hexabrix 320£) or non-ionic contrast media (Visipaque 270£) by using monochromatic
X-rays in vivo. SAP-MS which absorbed serum saline did not change the form after injection. The SAP which
absorbed ionic contrast media expanded the volume after injection. On the other hand, SAP which absorbed
non-ionic contrast media reduced the volume after injection. We succeeded in depicting the transformation
behavior. However, we could not measure the diameter of SAP, because borderline of SAP and contrast media
was unclear.
