An introductory overview for this topic. The article introduction is reproduced here, so you do not need to leave MedAtlas to read it. It may not match the latest official medical guidance.
Theranostics, or theragnostics, refers to the combination of diagnosis and therapy (treatment) of disease in a single medical intervention or technique. For example, a combination of radioactive isotopes may be administered to simultaneously image and treat cancerous lesions. Typically theranostic approaches involve a medical imaging component, such as radiotracers, contrast agents, positron emission tomography, and magnetic resonance imaging.
The term "theranostic" is a portmanteau of two words, therapeutic and diagnostic. The first known use of the term is attributed to John Funkhouser, a consultant for the company Cardiovascular Diagnostic, who used it in a press release in August 1998. Nanotheranostics is the specialization of theranostics in the nanoscale.
How this connects to MD Nuclear Medicine
The ear, nose and throat form connected sensory and airway systems. Sound conduction, inner-ear transduction, nasal airflow, swallowing and laryngeal function depend on separate structures and cranial nerves, so similar symptoms can arise from different anatomical locations.

What the underlying subject studies
At postgraduate and higher-specialty level, begin with normal anatomy and physiology of the relevant organ system, then compare distinct disease mechanisms, their evidence base and the limitations of available investigations.
How mechanisms and evidence connect
Advanced study requires evidence appraisal, multidisciplinary interpretation and a clear distinction between established facts, hypotheses and research findings. Procedural, diagnostic and prescribing skills must be learned under an accredited program.
How to develop a sound explanation
Identify the scope of this topic within the named specialty, connect it to the applicable patient population and formulate a structured question that can be answered using current specialty literature and supervised teaching.
