Hot Stuff: Thermal Imaging Aids in Cellulitis Diagnosis.

Cellulitis is commonly misdiagnosed, with resultant health care expenditures and complications from antibiotic overprescription. Ko et al. evaluate the use of thermal imaging to aid in the diagnosis of cellulitis, with promising results. Limitations include a small sample size and questionable applicability to bilateral leg findings, where cellulitis is unlikely regardless of temperature differential. Nevertheless, this technology has potential to improve patient care.
