At KIMS, nuclear medicine imaging procedures are non-invasive and, with the exception of intravenous injections, are usually painless medical tests that help physicians diagnose and evaluate medical conditions. Nuclear medicine examinations offer information that is unique – including details on both function and structure – and often unattainable using other imaging procedures. Nuclear medicine is less expensive and may yield more precise information than exploratory surgery which makes it perfect in diagnosis of poor patients with complicated diseases. It offers the potential to identify disease in its earliest stage, often before symptoms occur or abnormalities can be detected with other diagnostic tests. By detecting whether lesions are likely benign or malignant, PET scans may eliminate the need for surgical biopsy or identify the best biopsy location, also providing additional information that is used for radiation therapy planning.
