Nuclear medicine theragnostics: walk before you run

Gopinath Gnanasegaran NM nuclear medicine Shaunak Navalkissoor theragnostics

Theragnostic nuclear medicine is a much discussed topic in nuclear medicine and is currently discussed and debated in clinical oncology with great interest and optimism. Radionuclide theragnostics generally pairs diagnostic biomarkers with radiolabelled therapeutic agents that share a specific target within the diseased cells or tissues. The clinical indications are expanding, with evolving evidence. Incorporating radionuclide theragnostics in the cancer management algorithm might improve patient selection, predict treatment response and toxicity, and help prognostication. In addition, this could avoid expensive and frequent diagnostic and therapeutic procedures. On a positive note, there has been significant growth in the science and technology related to molecular imaging and therapy in theragnostic nuclear medicine. However, on a negative note, the most common hurdle would be the limited workforce and funding for smooth implementation and transition.

Artificial intelligence in detecting paediatric fractures: where are we now?

Paediatric fractures make up a large part of the acute paediatric workload both in the emergency department and community-based care, such as urgent care and walk-in centres. Paediatric fractures can be very subtle, posing a diagnostic challenge for the untrained eye. Missed fractures can have a significant impact in children, including opportunities to raise safeguarding […]

Adaptive radiotherapy and AI in head and neck cancer

Over 12,000 patients are diagnosed with head and neck cancer across the UK every year. Alcohol and tobacco use have long been established as primary risk factors for the development of these cancers. However, there has been a notable increase in the cases of oropharyngeal cancer in recent years, particularly those linked to the oncogenic […]

Improving PETCT using AI

Imagine a future where every PETCT scan delivers faster, sharper images and fewer diagnostic doubts or discrepancies – that is the potential transformative power of AI. I won’t take you through what AI, or machine learning (ML), is; for that can I simply direct you to another RAD Magazine article entitled ‘AI in multimodality imaging’ […]
