It was fascinating to watch the SIRT procedure on Thursday and see the Radiologist inserting the spheres. I had imagined there would be about 9 or 10 radioactively charged little ball-bearings positioned in blood vessels to target the metastases. Instead there were thousands of little cells, salmon coloured, each one measuring 30 microns and inserted in suspension in plain water. They were manually pulsed into the liver in a way that would allow the blood stream to pick them up for distribution. It is impossible to see the spheres once in the liver so placement is determined by the position of the catheter. The radiologist tried to ensure maximum coverage and penetration. A scan in 6 weeks will be the next indication of their effectiveness.
Radioactive spheres not what I thought.
