When is PET Imaging Conducted?


A positron emission tomography scan is often used to help doctors diagnose, monitor, and treat several cancers, including lung, lymphomas, and head and neck cancer. They also help them find tumor locations and determine if treatment is working for patients.

A PET scanner uses a radioactive tracer to show the abnormal (cancerous) cells in the body. Doctors can examine every part of a patient's body and identify cancer. Known as Fluorodeoxyglucose (FDG), the radioactive tracer is often attached to fluorine-18. When the glucose is absorbed by body cells, the fluorine-18 will break down and release gamma rays and positrons.

Cancer cells are always aggressive, and they grow and multiply fast as they take in more sugar. On PET scans, cancerous cells will glow brighter.

Here is why PET scans are conducted:

·         Sometimes doctors perform PET scans on neurology and cardiology patients.

·         And whenever a patient has symptoms, doctors will use a PET scan to determine the proper test needed to identify a problem and give the appropriate treatment.

·         Cancer that is discovered through PET imaging can be accurately staged based on its size and the extent to which it has metastasized.

·         Follow-up PET Scans are used to detect when a patient’s treatment is not working. This allows oncologists to stop the current treatment and find an alternative one that works well on the patient.

The latest advances in PET technology have enhanced imaging by providing more accurate and precise results during cancer diagnosis, staging, treatment, and monitoring. The PET scanner can fuse images in the body to deliver the entire picture of the cancerous tissue. This enhances the accuracy of diagnosis and minimizes the need for more scans by a patient.

PET imaging is a procedure that is entirely non-invasive and painless. It takes only 30 minutes to get a PET scan.

The Professionals Who Perform CT Scans at Centers in Texas

Computed Tomography scans use computer-enhanced X-rays to distinguish between tissue, bone, fat, fluid, and gas to get clear results that allow physicians to diagnose a problem and prescribe an appropriate course of treatment. CT scans are used for detecting and diagnosing brain tumors, blood clots, stroke, cancer, trauma, pancreatic disease, back problems, and enlarged lymph nodes. They provide a quick view inside the body to help doctors with the diagnosis. Computed tomography (CT) imaging requires team effort to provide the best results. The computed tomography patient care team in a full-service CT center is headed by a radiologist. The other members of the team include CT technologists and nurses who are specialists in administering injections. Each professional has important responsibilities for successful scan results. Here are the roles performed by board-certified clinical and CT professionals: • Clinical Radiologists – They are highly trained specialist medical doct

Cancer in Children Can Now Be Detected Faster

Generally, children find it difficult to sit still for long periods. This can make it difficult for doctors taking MRI/CT scans to get accurate results through conventional methods, the scan time averages an hour or longer. However, researchers from Stanford have found a way to reduce the time to 30 minutes or less per region. As an added bonus, this method also picks up more details. The patients in this study had leukemia, lymphoma, or sarcoma. • Ten participants: 10 pediatric cancer patients (5 boys and 5 girls) who had undergone chemotherapy, at an average of 18.7 months prior underwent PET/MR imaging . Head and joint MRI were performed at the same time with PET data acquisition being done as well, along with cardiac imaging, with and without enhancing the images. • Scanning time greatly reduced: The technicians were able to complete the brain scans in just 27 minutes, the bone scans in a time of 15 minutes as well as manage to do cardiac imaging within 19 minutes, a drast

Can CT Scans be used in Diagnosing COVID-19?

COVID-19 is often diagnosed through RT-PCR testing. Now some experts are arguing that CT scans can help to diagnose Covid-19 . But others disagree with them. The covid-19 epidemic continues to spread all over the world, killing many people as nations strive to find cure or vaccination. Diagnosing people with SARS-CoV-2 early is key to combating the spread of the disease. Once you are diagnosed, you can limit your physical contact with other people and slow down its spread. To many people, reverse transcriptase polymerase chain reaction (RT-PCR) is the gold standard for Covid-19 diagnosis. RT-PCR is a molecular biology technique that identifies material specific to the SARS-CoV-2 virus. However, RT-PCR does not provide 100% accuracy, which has raised concerns about the false-negative and false-positive results. So, is it possible that CT scans can serve as an adjunct to RT-PCR diagnosis? CT scans combine a series of images that reflect abnormal cells' metabolic activi
