Thermography as a Method for Bedside Monitoring of Infantile Hemangiomas
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Infantile hemangiomas occur in 3 to 10% of infants. To predict the clinical course and counsel on treatment, it is crucial to accurately determine the hemangiomas’ extension, volume, and location. However, this can represent ...
