IVUS (intravascular ultrasound) detects transplant rejection:

Executive Summary
Analysis of signals from intravascular ultrasound (IVUS) may be useful in determining the likelihood of transplant rejection, according to animal studies. Researchers at Stanford University School of Medicine in California, analysed radiofrequency signals from IVUS examinations of transplanted aortic grafts in six monkeys. They found a significant difference in signal intensity between the allograft and host aorta using a technique whereby RF signals are acquired in real time using a 500MHz digitiser with 8-bit resolution. Their results are published in the November edition of Circulation. The same difference could not be seen with conventional IVUS gray-scale images.
