Lymphoscintigraphy has emerged as the diagnostic test of choice in patients with suspected lymphedema. To assess the lymphatic circulation of 386 extremities in 188 patients, we prospectively recorded a semiquantitative index of lymphatic transport in addition to visual evaluation of lymphoscintigraphy image patterns. ⋯ Semiquantitative evaluation of the lymphatic transport with lymphoscintigraphy reliably depicts abnormalities in the lymphatic circulation. Lymphoscintigraphy excluded lymphedema as a cause of leg swelling in one third of our patients.
