Overview
Atomedical is a Portuguese nuclear medicine clinic based in Lisbon. It was founded in 1987 by a group of highly experienced professionals, some of whom were pioneers of nuclear medicine in Portugal. The clinic operates from a purpose-designed 500 m² facility dedicated to nuclear medicine, equipped with three dual-detector gamma cameras, including a GE Optima NM/CT 640 system that combines SPECT and CT for attenuation correction and anatomical-functional image fusion. All examinations are archived in a PACS system in accordance with current legislation. Quality control and maintenance programs are ensured through contracts with equipment suppliers' technical services and the laboratory's own technicians. The environment is continuously monitored by an automatic system to guarantee efficient radiation protection for patients, staff, and the surrounding area. Atomedical also has emergency power systems (UPS) to prevent interruption of examinations during power outages. The clinic emphasizes continuous professional training alongside technological development. The clinical team is led by Dr. Guilhermina Cantinho, a nuclear medicine specialist since 1986 and clinical director of Atomedical since 1987, who also held academic and clinical positions at the Institute of Nuclear Medicine of the Faculty of Medicine of Lisbon. Atomedical serves patients in Portugal, offering a range of nuclear medicine diagnostic exams.
