Nuclear Medicine
Molecular imaging and targeted radionuclide therapies, including PET-CT.

Medically reviewed by the Acıbadem clinical team — June 12, 2026
Nuclear medicine is the medical unit that uses small, safe amounts of radioactive material to diagnose and treat disease — imaging how organs and tissues are functioning, and delivering targeted treatment to specific conditions. Unlike standard imaging, which mainly shows structure, nuclear medicine shows function, which makes it especially valuable in cancer, heart, thyroid and other conditions. At Acıbadem International, nuclear medicine works closely with oncology, radiology and other specialties across a large hospital group, so that its unique insights are integrated into a patient’s overall care. For people travelling from abroad, that combination of advanced functional imaging and targeted treatment, within a coordinated hospital group, is what adds an important dimension to diagnosis and care.
This page explains what the nuclear medicine unit covers, how it differs from standard imaging, the techniques available, how it supports diagnosis and treatment, and how international patients are supported.
What the nuclear medicine unit covers
Nuclear medicine uses small amounts of radioactive material — given safely — to image function and treat certain conditions. Its main areas of work include:
- Functional imaging — showing how organs and tissues are working.
- PET scanning — particularly important in cancer.
- Cancer imaging — detecting, staging and monitoring cancers.
- Cardiac and other organ imaging — assessing function.
- Thyroid assessment and treatment.
- Targeted (theranostic) treatment — delivering treatment to specific conditions.
Because its insights are so often part of wider care, nuclear medicine works closely with oncology, radiology, radiation oncology and endocrinology, so that its findings and treatments are integrated into the patient’s plan.
How nuclear medicine differs from standard imaging
The key difference between nuclear medicine and standard imaging such as CT or MRI is that nuclear medicine shows function rather than mainly structure. A small amount of a radioactive substance is given — usually injected — and it travels to specific organs or tissues, where a special camera detects it and reveals how those areas are working. This functional information is uniquely valuable: it can show, for example, how active a tumor is, how well the heart muscle is functioning, or how the thyroid is behaving — things that structural imaging alone may not reveal. The amounts of radioactive material used are small and given safely. This ability to see function, complementing the structural detail of radiology, is what makes nuclear medicine such an important and distinctive tool in modern medicine.
Techniques and applications
The unit provides a range of nuclear medicine techniques, each suited to particular purposes.
PET scanning
PET imaging shows the activity of tissues and is particularly important in cancer — helping to detect cancer, determine how far it has spread (staging), and assess how it is responding to treatment. Often combined with CT, it provides both functional and structural information together.
Cancer imaging and monitoring
Beyond PET, nuclear medicine techniques help detect, stage and monitor cancers, providing information that guides the cancer team’s decisions, in close cooperation with oncology.
Cardiac and organ function imaging
Nuclear medicine can assess how well the heart muscle and other organs are functioning, providing information that complements other tests.
Thyroid and targeted treatment
Nuclear medicine both assesses and treats certain thyroid conditions, and targeted treatments deliver therapy directly to specific conditions. Specific procedures can be explored in the treatments library.
The unique value of functional imaging
The greatest strength of nuclear medicine is its ability to reveal function, which adds a dimension that structural imaging alone cannot provide. Knowing not just what something looks like but how it is behaving can be decisive — showing whether a tumor is active, whether treatment is working, or how an organ is functioning. In cancer in particular, this functional information is invaluable for staging and for assessing response to treatment, helping the cancer team make better-informed decisions. By complementing the structural detail of radiology with functional insight, nuclear medicine helps build a more complete picture of a patient’s condition. This is why it has become an important part of modern diagnosis and care, especially in oncology.
Theranostics: imaging and treatment combined
One of the most exciting aspects of nuclear medicine is its ability not only to image disease but to treat it, using targeted treatments sometimes described as theranostics. The same principle that allows a radioactive substance to travel to specific tissues for imaging can, with the right agents, be used to deliver treatment directly to certain conditions — for example, certain thyroid conditions and some cancers. This targeted approach aims to direct treatment to where it is needed while limiting effects elsewhere. These treatments are used in carefully selected situations, as part of a coordinated plan with the relevant specialists. This dual role — imaging and treatment — makes nuclear medicine a distinctive and increasingly important field, and the unit’s capability adds a valuable dimension to the hospital group’s care.
Is it safe?
A natural question is whether nuclear medicine, which uses radioactive material, is safe — and the answer is that the amounts used are small and given in a controlled, carefully managed way. Nuclear medicine has been used safely for many years, and the unit follows strict safety standards. The radioactive substances used for imaging are chosen to provide the necessary information with as little exposure as possible, and they leave the body over time. For targeted treatments, the approach is carefully planned and managed. The unit explains the process to patients clearly, so that any concerns are addressed and patients understand what to expect. Safety is managed carefully throughout, allowing patients to benefit from the unique insights and treatments that nuclear medicine provides with confidence.
Technology and approach
Nuclear medicine combines specialized imaging and treatment technology with expert interpretation and careful integration into care. The unit uses techniques such as PET to reveal function, often combined with CT for structural detail, and provides targeted treatments in selected situations, all managed to strict safety standards. But the defining feature is integration: the unique functional information nuclear medicine provides is most valuable when woven into a patient’s overall plan, in cooperation with oncology, radiology and other specialties. This combination of distinctive capability and coordinated care is what makes nuclear medicine so valuable.

What to expect and practical notes
A nuclear medicine scan involves receiving a small, safe amount of a radioactive substance, usually by injection, after which imaging is performed; the process is explained clearly so you know what to expect. The amounts used are small and managed to strict safety standards. The real value lies in the functional information provided and how it is integrated into your care, so the findings are interpreted by experienced physicians and shared with your specialists. For targeted treatments, the approach is carefully planned. Throughout, nuclear medicine serves your diagnosis and treatment as part of coordinated care.
Nuclear medicine within coordinated care
Nuclear medicine is most valuable when integrated into wider care, and being part of a large hospital group makes this possible. Its functional imaging supports the cancer team alongside oncology and radiation oncology; it complements the structural imaging of radiology; and it works with endocrinology in thyroid conditions. This integration means the unique insights and treatments of nuclear medicine are woven into a patient’s coordinated plan rather than standing apart, which is exactly how they add the most value. For patients, especially those with cancer, this coordinated use of nuclear medicine is an important strength of a leading hospital group.
PET imaging in cancer care
One of the most important applications of nuclear medicine is PET imaging in cancer care, where it provides information that other scans cannot. By showing how tissues are functioning rather than only how they look, PET imaging can help detect cancer, assess how far it has spread, and evaluate how it is responding to treatment. This functional information is highly valuable to the cancer team, working alongside medical oncology and radiation oncology, in planning and monitoring treatment. The unit performs these examinations to high standards and interprets them as part of the wider clinical picture, within the multidisciplinary team. For patients on a cancer journey, this advanced imaging plays a key role in ensuring that treatment is guided by accurate, detailed information about how the disease is behaving — which is central to giving the best chance of a good outcome.
Thyroid and other applications
Beyond cancer, nuclear medicine has important applications in conditions of the thyroid and other organs. In thyroid disease, nuclear medicine techniques can both assess how the gland is functioning and, in certain conditions, provide treatment, working alongside endocrinology. Functional imaging also helps assess the heart, bones, kidneys and other organs, providing information about how they are working that complements the structural detail of other scans. This breadth reflects the unique role of nuclear medicine: by revealing function rather than only structure, it answers questions that other forms of imaging cannot. The unit applies these techniques across a range of conditions, always as part of a coordinated clinical picture, so that the functional information they provide contributes meaningfully to diagnosis and treatment in cooperation with the relevant specialties.
What to expect during a scan
Patients are often unfamiliar with nuclear medicine and may have questions about what a scan involves, and the unit takes care to explain the process clearly. A nuclear medicine examination typically involves a small amount of a radioactive tracer, given so that the imaging can show how tissues are functioning, followed by imaging after an appropriate interval. The examinations are carried out safely, with the amounts used kept to the minimum necessary, and the team explains any preparation needed and guides the patient through the process. The unit is happy to address the natural questions patients have about safety and what to expect, providing clear, reassuring information. This careful explanation and attention to the patient experience — alongside the technical and clinical quality of the imaging — ensures that patients undergo these valuable examinations with understanding and confidence.
