Scintigraphy may prove helpful for identifying potential sites for biopsy to aid the histologic diagnosis when the clinical diagnosis is in doubt (ie, because of unfulfilled diagnostic criteria).

Technetium-99m methylene diphosphonate bone scintigraphy has been used in the evaluation of chest pain, allowing identification of possible sites for biopsy in costochondral tissues.

Gallium-67 citrate scintigraphy has also been found to show increased uptake in affected areas.
