What are the different types of oncologists?
There are several types of oncologists, including:
Medical Oncologists who use chemotherapy, targeted therapy, and immunotherapy to treat cancer.
Radiation Oncologists who use radiation therapy to target and destroy cancer cells.
Surgical Oncologists who perform surgeries to remove tumors and affected tissues.
Pediatric Oncologists who specialize in treating cancer in children.
Gynecologic Oncologists who focus on cancers affecting the female reproductive system.
What is oncology?
Oncology is the branch of medicine that specializes in the diagnosis, treatment, and study of cancer. Oncologists are medical professionals who focus on treating various types of cancer through methods like surgery, chemotherapy, radiation therapy, immunotherapy, and more.
How long does it take to get results from a nuclear medicine scan?
The time for results can vary depending on the specific scan. In some cases, initial results may be available shortly after the scan, while more detailed analysis may take a bit longer. Your doctor will discuss the timeline for receiving and discussing the results with you.
Is a SPECT/Gamma Camera Scan safe, and does it involve radiation exposure?
While a SPECT/Gamma Camera Scan involves the use of a radioactive tracer, the amount of radiation exposure is typically considered safe for diagnostic purposes. The radioactive material used has a short half-life, meaning it loses its radioactivity quickly.
Are there any specific preparations I need to undertake before a SPECT/Gamma Camera Scan?
Your doctor will provide specific instructions based on the type of scan you are undergoing. Generally, you may be asked to avoid certain foods or medications before the scan. It is essential to inform your healthcare provider about any allergies, medical conditions, or if you are pregnant or breastfeeding.
How do doctors use radioactive drugs and imaging tools to identify diseases?
Radioactive drugs and imaging devices are commonly used in a medical technique called nuclear medicine to diagnose diseases. Radiotracers are special drugs containing a small amount of radioactive material. They are designed to emit gamma rays, which can be detected by imaging devices. Radiotracers can be administered in various ways, such as injection, ingestion, or inhalation, depending on the specific diagnostic procedure and the area of the body being examined. Once administered, the radiotracer circulates through the body and accumulates in the target organ or tissue. Imaging devices, such as gamma cameras or positron emission tomography (PET) scanners, are used to capture the gamma rays emitted by the radiotracer. As the radiotracer emits gamma rays, the imaging device creates detailed pictures or scans of the internal structures and functions of the body. Differences in the distribution or concentration of the radiotracer can indicate abnormalities, such as tumours, inflammation, or other diseases, helping in the diagnosis and staging of conditions.
Are there any contraindications to radioactive iodine therapy?
Yes, there are certain contraindications or situations where radioactive iodine therapy may not be recommended. Some common contraindications include: Pregnancy and breastfeeding Severe thyroid eye disease Uncontrolled hyperthyroidism Vomiting and diarrhoea
Is a PSMA PET scan safe?
Yes, a PSMA PET scan is considered safe. The radioactive substance used in the scan has a low level of radiation, and the benefits of accurate cancer detection typically outweigh the minimal risks.
How do I prepare for a PSMA PET scan?
Preparation usually involves fasting for a few hours before the scan, and your doctor will provide specific instructions. It is essential to inform your doctor about any medications or allergies.
How long does a PSMA PET scan take?
A PSMA PET scan usually takes around 1 to 2 hours. This includes the time for the injection and the actual imaging process.
