He was known for naming a hot nodule of leprosy, erythema nodosum leprosum (ENL).

An I scan showing a hot nodule, accompanied by a lower than normal TSH, is strong evidence that the nodule is not cancerous.

Depending on the dose of radioiodine chosen, and the disease under treatment (Graves' vs. toxic goitre, vs. hot nodule etc.), success rate in achieving definitive resolution of the hyperthyroidism may vary from 75-100%.
