It is not known whether this deposition changes over time in absence of specific therapy. We repeated in two years a PET/CT scan using 18F-NaF as a radiopharmaceutical in patients with the disease and compared the deposition at skin and vessel. Furthermore, calcium score values at the vessel wall were also assessed. Main results indicate in the vessel walls that calcification progressed in each patient; by contrast, the active microcalcification, measured and target-to-background ratio showed reduced active deposition. By contrast, at skin levels (neck and axillae) the uptake of the pharmaceutical remains unchanged. In conclusion, because calcification in the arterial wall is not specific for pseudoxanthoma elasticum condition, the measurement of the deposition of 18F-NaF in the neck might be potentially used as a surrogate marker in future trials for the disease. 10.3390/jcm10122588 2077-0383 Journal of Clinical Medicine http://hdl.handle.net/10668/4491 34208205 http://hdl.handle.net/20.500.12105/18374 Pseudoxanthoma elasticum Inorganic pyrophosphate Microcalcification 18F-NaF PET/CT Seudoxantoma elástico Pirofosfatasa inorgánica Calcinosis Fluoruro de sodio Tomografía computarizada por tomografía de emisión de positrones Tejido elástico Cutaneous and Vascular Deposits of 18F-NaF by PET/CT in the Follow-Up of Patients with Pseudoxanthoma Elasticum
