Cancer Scintigraphy: Nuclear Medicine Imaging for Diagnosis and Treatment

Cancer Scintigraphy: A Comprehensive Guide to Diagnosis and Imaging

Cancer is a fatal disease affecting millions of people worldwide, and early diagnosis is vital. Medical technologies used in cancer diagnosis and treatment are continuously evolving, and scintigraphy in the field of nuclear medicine holds an important place among these technologies. Scintigraphy is a precise and reliable imaging technique that helps detect cancer cells and determine the extent of disease spread. In this article prepared for you, we will provide information about what scintigraphy is, what it does, and how it is performed.

What is Scintigraphy?

Scintigraphy is an imaging method used in nuclear medicine in which radioactive substances are injected into the body to examine the function of organs and tissues. In this method, the radioactive substance is selected based on the diseased area and, after being injected into the body, images are obtained using a gamma camera. Scintigraphy is aimed at examining the internal structure of the body and the functions of organs, and is particularly effective in detecting cancer cells and determining the presence of metastasis.

What is Scintigraphy Used For?

Scintigraphy plays an important role in cancer diagnosis and treatment. The detection of cancer cells helps in the early diagnosis of the disease and the determination of appropriate treatment methods. Additionally, it is effective in determining the extent of disease spread (metastasis). Scintigraphy allows for the detection of cancer cells in many organs such as the thyroid, kidneys, bones, heart, and brain by examining their functions.

Radioactive substances are called radiopharmaceuticals and can be administered intravenously or orally. These substances accumulate in the relevant organ or tissue in the body and emit gamma rays; the gamma camera detects these rays and creates images of the organs and tissues. The main applications of scintigraphy include:

• Cancer
• Heart disease
• Stroke
• Infections
• Thyroid disorders
• Bone diseases
• Kidney disease
• Liver disease
• Gastrointestinal system disorders

Furthermore, scintigraphy can be used to evaluate the function of an organ or tissue, monitor the progression of a disease, observe response to treatment, and guide surgical or other interventions when necessary.

How is Scintigraphy Performed?

Scintigraphy imaging begins with the injection of a radioactive substance into the body. This substance is typically injected intravenously and is selected based on the diseased area in the body. After the radioactive substance is injected into the body, the patient may need to wait for a period of time. This duration is necessary for the substance to distribute throughout the body and reach the target organ.

After the waiting period is complete, the patient is placed in front of a device called a gamma camera. The gamma camera detects the rays emitted by the radioactive substance and obtains images. These images are evaluated by a physician to gain information about the disease status and spread level. During scintigraphy imaging, it is important that the patient does not experience discomfort and remains still, as movement can reduce image quality and make obtaining accurate results difficult. The procedure is generally considered relatively painless, and the total duration is usually approximately 30 minutes; however, this time may vary depending on the organ being examined and the radioactive substance used.

What are the Types of Scintigraphy?

Scintigraphy is an imaging method that uses radioactive substances and shows the functions of organs in the body. Scintigraphy is used to evaluate how organs in the body function and their structures. Through this method, important information is obtained for the diagnosis and treatment of organ diseases. The types of scintigraphy are as follows:

Bone Scintigraphy: Used to detect damage, fractures, infections, and tumors in bones. It also holds an important place in the diagnosis and monitoring of bone metastases.

Thyroid Scintigraphy: Used to evaluate the function and structure of the thyroid gland. Detection of nodules, inflammation, and cancer cells in the thyroid gland can be performed with this method.

Parathyroid Scintigraphy: Used to evaluate the function and structure of the parathyroid glands. Detection of adenomas, hyperplasia, and cancer cells in the parathyroid glands can be performed with this method.

Myocardial Perfusion Scintigraphy: Used to evaluate the blood supply and function of the heart muscle. It is used in the diagnosis and monitoring of heart diseases such as coronary artery disease, heart attack, and heart failure.

Renal Scintigraphy: Used to evaluate the function and structure of the kidneys. It is used in the diagnosis and monitoring of kidney diseases such as kidney failure, kidney stones, and kidney infections.

Pulmonary Scintigraphy: Used to evaluate the function and structure of the lungs. It is used in the diagnosis and monitoring of lung diseases such as pulmonary embolism, lung cancer, and lung infections.

What is Nuclear Scintigraphy and How Does it Work?

Nuclear scintigraphy is a medical imaging technique in which images of internal organs and tissues in the body are created using radioactive substances. These substances, called radiopharmaceuticals, are given intravenously or orally, mix with blood or tissues, accumulate in the organ or tissue of interest, and emit gamma rays. A special camera detects these rays and creates images.

The radiopharmaceuticals used are in very small quantities and are designed to bind to molecules specific to a particular organ or tissue; in this way, the substance accumulates in the desired area and is more easily distinguished in the images. The images obtained as a result of nuclear scintigraphy are called "scintgrams." Scintgrams can also be evaluated together with other imaging methods such as X-ray, computed tomography (CT), and magnetic resonance imaging (MRI) to obtain more comprehensive information about the patient's condition.

What are the Advantages of Scintigraphy?

The scintigraphy method has some outstanding features in functional evaluation of organs and tissues:

• Sensitivity: Due to the specific uptake of radiopharmaceuticals by certain tissues or organs, it can help identify findings that are not clearly visible in other imaging methods in some cases.

• Non-invasiveness: Since it does not require surgery or an interventional procedure, it is generally a comfortable option for the patient.

• Quick and practical application: The procedure can be completed in a relatively short time in the form of administering the radiopharmaceutical and then waiting under the camera.

• Accessibility: Scintigraphy is one of the imaging options that can be preferred for evaluating organ functions or disease monitoring.

When are Scintigraphy Results Available?

The scintigraphy procedure is performed by waiting for a certain period after injecting the radioactive substance into the body. This duration may vary depending on the radioactive substance used and the organ to be examined. The procedure duration typically ranges from 30 minutes to 2 hours. Scintigraphy results are evaluated by a nuclear medicine specialist after the procedure is completed. Results are typically reported on the same day. However, in some cases, evaluation and reporting of results may take several days.

What are the Side Effects of Scintigraphy?

Scintigraphy is generally a safe procedure and does not cause serious side effects. However, some individuals may experience allergic reactions to the radioactive substance. This is quite rare and usually presents with mild symptoms. Additionally, temporary pain or redness may occur at the injection site of the radioactive substance. Rarely, symptoms such as nausea, vomiting, headache, and dizziness may be reported.

In terms of radiation exposure, scintigraphy uses low-dose radiation and therefore the risk is minimal. However, it should be noted that radiation-related risks may increase as the total amount of radiation exposure increases (for example, if the procedure is repeated). Pregnant and breastfeeding women are advised to avoid scintigraphy. Additionally, it is important to drink plenty of water and urinate to help the radioactive substance eliminate from the body. This further reduces radiation exposure. It is recommended to discuss any allergic conditions with your doctor before the procedure and to discuss the possible risks and benefits of the procedure with your doctor.

What Should be Done Before the Scintigraphy Method

Scintigraphy is a medical imaging method using radionuclides called radioactive substances that evaluates the functions of organs in the body. Patients must perform certain preparatory steps before the scintigraphy method. The considerations that should be paid attention to before the scintigraphy method can be explained as follows:

Before scintigraphy, you may continue or stop taking your medications under your doctor's supervision. Inform your doctor of all medications, vitamins, and supplements you take.

Before the scintigraphy method, a fasting period of generally 4-6 hours is usually required. During this time, you can only drink water. If your doctor recommends a special diet, you should follow it accordingly.

Since the scintigraphy method uses radioactive substances, it is important that pregnant or breastfeeding women inform their doctors of this condition. If necessary, the doctor may recommend a different imaging method.

If you are allergic to radioactive substances or medications, inform your doctor. In this case, your doctor will take necessary precautions before the scintigraphy method.

It is recommended that you wear comfortable clothing during scintigraphy and avoid metal accessories if possible. Metal accessories may affect the imaging process.

Most Common Cancer Types Using Bone Scintigraphy

Bone scintigraphy is an imaging method that shows abnormal changes occurring in the bones. When cancer cells spread to the bones, this test becomes particularly important. Bone scintigraphy can be used for early detection of metastases (spread of cancer from another organ to the bones). The most common cancer types using bone scintigraphy are as follows:

Prostate cancer is one of the most common types of cancer in men. In advanced prostate cancer cases, cancer cells may spread to the bones. For this reason, bone scintigraphy plays an important role in staging prostate cancer and treatment planning.

Breast cancer is the most common type of cancer in women. In advanced breast cancer, cancer cells tend to spread to the bones. Bone scintigraphy is used in the staging and treatment process of breast cancer.

Lung cancer is one of the most deadly cancer types worldwide. Cancer cells can spread from the lungs to the bones. In this case, bone scintigraphy is used in the monitoring and treatment processes of lung cancer patients.

Thyroid cancer originates primarily from the thyroid gland located in the neck region. In advanced thyroid cancer cases, cancer cells may spread to the bones. Bone scintigraphy is an important tool in staging thyroid cancer and treatment planning.

Multiple myeloma is a type of blood cancer that results from abnormal proliferation of plasma cells. In patients with multiple myeloma, abnormal changes and fractures may occur in the bones. For this reason, bone scintigraphy is used in the diagnosis and treatment of multiple myeloma patients.

How is Bone Scintigraphy Performed?

Bone scintigraphy is a medical test that obtains an image of the bones in the body using a radioactive substance. The bone scintigraphy procedure is explained step by step as follows:

Before the procedure begins, a radioactive substance is injected into the patient. This substance spreads to the bones in the body, allowing abnormal changes to be visualized in the obtained images.

A period of time is allowed for the radioactive substance to spread to the bones in the body. This duration typically ranges from 2 to 4 hours.

After the radioactive substance has spread to the bones, a special camera is placed over the patient. This camera detects the rays emitted by the radioactive substance and creates images of the bones.

The obtained images are evaluated by a radiologist. The radiologist identifies abnormal changes in the images and determines whether cancer cells have spread to the bones.

Based on bone scintigraphy results, the doctor creates a treatment plan for the patient. If cancer cells have spread to the bones, the patient may be administered chemotherapy, radiotherapy, or other treatment methods.
