The utility of bone scintigraphy with SPECT/CT in the evaluation and management of frostbite injuries.

OBJECTIVE

: Frostbite is a localized cold-thermal injury resulting from prolonged exposure of flesh to freezing and near freezing temperatures. The depth and extent of frostbite injuries are not easily assessed, from a clinical standpoint, at the time of injury making it challenging to plan appropriate management and treatment.

METHODS

: A review of the literature of management of cold-related injuries and retrospective case review of the imaging and clinical course of frostbite injury.

RESULTS

: Bone scintigraphy with single photon emission computed tomography (SPECT)/CT was performed in the acute and subacute course of frostbite injuries, subsequently leading to earlier definitive management and shorter hospital stay.

CONCLUSION

: Multiphase technetium-99m-methylenediphosphonate (mTc-MDP) bone scintigraphy with SPECT/CT can expedite clinical management of frostbite injuries by determining the extent of injury and can accurately predict the level of amputation if needed.

ADVANCES IN KNOWLEDGE

: SPECT/CT is underutilized at many facilities but can have a profound and immediate impact on clinical management of patients with frostbite when used in combination with physiological bone scan imaging.
