PET Scan - Ronny Allan - Living with Neuroendocrine Cancer

Tag: PET Scan

A procedure in which a small amount of radioactive substance is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the substance is taken up. Because cancer cells often take up more of the selected substance than normal cells (often tumour specific), the pictures can be used to find cancer cells in the body. Also called positron emission tomography scan.

Understanding your Somatostatin Receptor (SSTR) PET Results

Patient Advocacy

Background In my online patient group, there is constant discussion about the meaning of both pictures and words on scan reports. The one that seems to cause the most confusion is PET scans, mainly somatostatin receptor (SSTR) PETs such as Ga68 and Cu64 variants. Worth adding that it's the addition of a nuclear tracer that makes PETs seem different. Generally speaking, the PET hardware is essentially the same. Most have a built-in CT scan, much less frequently an MRI scan. Confusion is often triggered by healthcare system processes where the patient receives the report before the appointment to discuss the results with the referring physician. Cue anxiety because the average patient reader does not understand and certain words cause them to worry, often unnecessary worry. The patient then becomes impatient…

Prospective Phase II Trial of Prognostication by 68Ga-NOTA-AE105 uPAR PET in Patients with Neuroendocrine Neoplasms: Implications for uPAR-Targeted Therapy

Clinical Trials

Summary A novel PET radiotracer can accurately assess the presence of a biomarker that indicates the level of tumor aggressiveness in neuroendocrine neoplasms (NENs). According to research published in the September issue of The Journal of Nuclear Medicine, the detection of the biomarker provides useful information for physicians to provide personalized care for patients with NENs and may also serve as a potential target for peptide radionuclide therapy (PRRT) for NEN patients.What is uPAR? Tumorigenesis (the production or formation of a tumour or tumours) is closely related to the loss of control of many genes. Urokinase-type plasminogen activator receptor (uPAR), a glycolipid-anchored protein on the cell surface, is controlled by many factors in tumorigenesis and is expressed in many tumor tissues. What is different about targeting uPAR instead of somatostatin receptors? uPAR expression…

New PET findings after COVID-19 vaccination: Keep Calm and Carry On?

Patient Advocacy

After a few months of introducing C-19 vaccines, many cases of false-positive lymph nodes were reported on nuclear PET scans, some of which led to unnecessary biopsies and unnecessary worry for the patients concerned.According to Mayo Clinic, the positive nodes were on the same side as the vaccine shot in the cases where the injection site was known. Mayo added that some cases had uptake in the deltoid muscle, which is normally where vaccine injections are given, leading to increased suspicion of false positive in cases where uptake was in both deltoid muscle and axillary lymph nodes (armpit). At least one case was found in the supraclavicular nodes (clavicle area), but it was noted that might have been a stronger immune reaction due to the patient undergoing immunotherapy.This issue had…
