SPECT Archives

Tag: SPECT

A special type of computed tomography (CT) scan in which a small amount of a radioactive drug is injected into a vein and a scanner is used to make detailed images of areas inside the body where the radioactive material is taken up by the cells. SPECT can give information about blood flow to tissues and chemical reactions (metabolism) in the body. Also called single-photon emission computed tomography.

Updated December 2025 Background Scanning is a key diagnostic support and surveillance tool for any cancer. Even though you have elevated bloods or urine (....or not), a picture of your insides is really like a thousand words.... and each picture has a story behind it. Scanning can be a game changer in the hunt for tumours and although scans do not normally confirm the cancer type and grade, they certainly help with that piece of detective work and are key in the staging of the cancer. When I read stories of people in a difficult diagnosis, I always find myself saying 'a scan…

Detectnet™ (64Cu-DOTATATE) – an expansion of the Somatostatin Receptor PET Imaging for Neuroendocrine Cancer

Updated Jan 2026What is 64CU dotatate It’s a high‑resolution PET tracer for imaging somatostatin‑receptor–positive neuroendocrine tumours (NETs), offering better lesion detection, longer imaging windows, and lower positron energy than 68Ga‑labelled agents. It consistently produces high tumour‑to‑background contrast and often finds additional metastatic sites missed by older SPECT agents like 111In‑octreotide. 🧬 64Cu‑DOTATATE vs 68Ga‑DOTATATE A clear, patient‑friendly comparison Both scans are excellent for finding neuroendocrine tumours (NETs). They work in the same basic way: a tracer attaches to somatostatin receptors on NET cells, and a PET/CT scanner shows where those cells are. The differences mainly relate to image clarity, timing,…
