Functional and anatomic information are often considered together when physician wants to obtain a more reliable diagnosis in medicine. The image quality and quantitative accuracy of radionuclide imaging, however, often lack anatomic cues that are needed to localize or stage the disease and typically has poorer statistical and spatial characteristics than anatomic imaging methods, such as MRI, ...
Cells communicate with one another not only by cell-cell contact, but also via the elaboration of soluble mediators or cytokines. The functionally distinct repertoire of secreted cytokines of Th1/Th2 cells has been shown to play an important role in the pathogenesis of inflammatory diseases. Effector Th1 cells secretes predominantly IFN- γ and IL-2 and regulates cell-m...
background: measurement of absolute or differential renal function using radiotracers plays an important role in the clinical management of various renal diseases. gamma camera quantitative methods in approximation of renal clearance may potentially be as accurate as plasma clearance methods. however some critical factors such as kidney depth and background counts are still troublesome in the u...
Objective(s):Lutetium-177 can be made with high specific activity and with no other isotopes of lutetium present, referred to as “No Carrier Added” (NCA) 177Lu. We have radiolabelled DOTA-conjugated peptide DOTA‐(Tyr3)‐octreotate with NCA 177Lu (“NCA-LuTATE”) and used it in nearly 40 therapeutic administrations for subjects with neuroendocrine tumours or meningiomas. In this paper, we report on...
Objective(s): To investigate and compare quantitative accuracy of kidney absorbed dose measures made from both 2D and 3D imaging in patients receiving 177LuDOTATATE (Lutate) for treatment of neuroendocrine tumours (NETs). Methods: Patients receiving Lutate therapy underwent both whole body planar imaging and SPECT/CT imaging over the kidneys at time points 0.5, 4, 24, and 96-120 hours after inj...
