@MickeySegal

given that current techniques can go much further than just lucency or not, e.g. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5443345/, I wonder if this modifier is relevant for modern diagnostics? For instance, "Uric acid stones are typically 200–400 HU, whereas calcium oxalate stones are ~600–1,200 HU". I realize there may be an earlier part of the workup where less is known, but would clinical decisions typically be made on the basis of this (I do not know)

The radiolucent term seems to be in current use: https://www.ncbi.nlm.nih.gov/books/NBK100238/ "Radiolucent kidney stones, detected by ultrasound or computed tomography (CT). Stones are not seen on a plain abdominal x-ray."

I am adding a section called Radiographic modifier

Under this, I added the following

Radiolucent HP:0025789 def: Applies to a lesion that allow x-rays to penetrate through them and expose the receptor (radiolucency). Soft tissues appear black or dark on the processed radiograph and are called radiolucent.
