Lymphatic Imaging Tests a New Technique

A modified interstitial approach uses intradermal contrast injection with rapid digital acquisition.

1

Rapid interstitial digital subtraction lymphangiography (DSLA) achieved 97% technical success in visualizing the peripheral lymphatic system in a porcine study.
2

Image quality was rated good in 52% of limbs, fair in 38%, and poor in 10%, with high interreader agreement on image quality.
3

The mean time to visualize superficial inguinal lymph nodes was approximately 75 seconds, with no major complications reported.
4

Minor injection site edema occurred in 27% of limbs but resolved spontaneously within 24 hours after the procedure.
5

The study's findings may not directly translate to humans due to anatomical differences, and further research is needed in disease states.
