Radiopharmaceutical

<p>Radiopharmaceuticals, or medicinal radiocompounds, are a group of <a href="/facts/Pharmaceutical_drug/h9mhwWP2">pharmaceutical drugs</a> containing <a href="/facts/Radioactive_isotope/5WpCfbdq">radioactive isotopes</a>. Radiopharmaceuticals can be used as <a href="/facts/Medical_diagnosis/J47rvb0p">diagnostic</a> and <a href="/facts/Therapy/2ytkGbgT">therapeutic</a> agents. Radiopharmaceuticals emit radiation themselves, which is different from <a href="/facts/Contrast_media/uVoPWL7Q">contrast media</a> which absorb or alter external electromagnetism or ultrasound. <a href="/facts/Radiopharmacology/EArnJn3N">Radiopharmacology</a> is the branch of pharmacology that specializes in these agents.
</p><p>The main group of these compounds are the <a href="/facts/Radioactive_tracer/0210Jncn">radiotracers</a> used to diagnose dysfunction in body <a href="/facts/Tissue_(biology)/H7CpML7A">tissues</a>. While not all <a href="/facts/Medical_isotopes/p1HJ0Pzo">medical isotopes</a> are radioactive, radiopharmaceuticals are the oldest and remain the most common of such drugs.
