The system uses a gamma camera to acquire projections data that are detected using a parallel hole collimator.
34 Lymphoscintigraphy uses a gamma camera to assess the drainage of injected radiotracer via the lymphatic capillaries to the larger collector lymphatics until it either passes through, or is retained within, the regional lymph nodes.
LSG uses a gamma camera to assess the drainage of injected radiotracer via the lymphatic capillaries to the larger collector lymphatics until it either passes through, or is retained within, the regional lymph nodes [ 66].
Renal imaging was performed using a gamma camera (BrightView, Philips Healthcare, Andover, MA, USA) with a low-energy high-resolution collimator.
Imaging positron-emitters, such as 18F-fluorodeoxyglucose (FDG), using a gamma camera in coincidence mode is an exciting development in recent years.
This abnormal clearance pattern can be visualised for the entire lung using a gamma camera to follow the movement of an inhaled radioaerosol.
Ex-vivo static planar images of the kidneys were acquired for determination of the differential renal function of tracer distribution using a gamma camera.
Since 1972, attempts were already made at our institution using a gamma camera to depict the distribution of the positron-emitting radionuclides produced in patients being irradiated with 42-MV photons from a betatron.
Whole-body anterior/posterior planar images were acquired at 1, 24, 48, and 72 h post-administration using a gamma camera (Symbia T6, Siemens AG, Erlangen, Germany) with LMEGP collimators.
Subsequent scintigraphic studies used a gamma camera SNC-5100RR, matrix size of 512 × 512 pixels, field of view 51×3838 cm, parallel-hole low-energy (high resolution) collimator; Shimadzu, Kyoto, Japan).
Whole-body images, anterior and posterior views (scan speed 10 (evaluation group) or 15 (treatment group) cm/min, matrix 256 × 1024), were obtained using a gamma camera equipped with low-energy high-resolution parallel hole collimators (Maxxus; General Electric, Milwaukee, USA (evaluation group) or MultiSPECT2; Siemens Healthcare Diagnostics Inc. Deerfield, IL, USA (treatment group)).
