Método digital para dar seguimiento a la eficiencia de terapias o fármacos en el sistema óseo

| Sumario: | Introduction. One way to monitor the efficacy of therapies in bone disease is by digitally subtracting two images, one taken before starting treatment and the other after completing it. This article describes a method based on a more practical photographic process, which does not require as much care in taking x-rays. The graphs illustrate what is happening with bone density, so that the evolution of the disease can be rapidly inferred. Material and methods. The x-rays and mammograms analyzed were obtained from a patient with breast cancer and metastasis in the humeral head of the right shoulder. To show the efficacy of the method, the humeral head and the surgical neck were analyzed. The time interval between the first and second x-rays was one year and for the mammograms the difference was 6 months. |
