45 The EANM practice guideline for Bone Scintigraphy Table 2. Suggested views and image acquisition parameters for skeletal scintigraphy of major joints using multimodality SPECT/CT equipment. Wrist/hand Static blood pool Static delayed‡ SPECT/CT§ Indication • Routinely recommended • Immediately following the injection of the radiotracer, place both hands (palms down) on the camera. Indication • Routinely recommended Indication • If planar imaging is nondiagnostic, usually late phase SPECT/CT Acquisition • Planar images • 256 x 256 matrix • LEHR or LEGP collimators • 2-5 minutes per view Acquisition • Planar images • 256 x 256 matrix • LEHR collimators • 5 minutes/500 kcts per view Acquisition SPECT • LEHR collimators, Matrix 128 x 128 • 128 angles, 20 seconds/angle • Step mode, Non-circular rotation Attenuation correction/ localization CT • 2.5 – 40 mA, 80 – 130 keV • 1 – 5 mm slice thickness Diagnostic CT • 40 – 335 mA, 80 – 130 keV • 0.33 – 2.0 mm slice thickness Hips Static blood pool Static delayed‡ SPECT/CT§ Indication • Routinely recommended • Depending on the size of the replacement, two images maybe required to ensure the whole area is covered. Indication • Routinely recommended • Depending on the size of the replacement, two images maybe required to ensure the whole area is covered Indication • If planar imaging is nondiagnostic, usually late phase SPECT/CT • Particularly useful for the evaluation of hip prosthesis Acquisition • Anterior and posterior images • 256 x 256 matrix • LEHR or LEGP collimators • 2-5 minutes per view Acquisition • Anterior and posterior images • 256 x 256 matrix • LEHR collimators • 5 minutes/ 500 kcts per view. This may depend on how full the bladder is for example. Acquisition SPECT • LEHR collimators, Matrix 128 x 128 • 128 angles, 20 seconds/angle • Step mode, Non-circular rotation Attenuation correction/ localization CT • 2.5 – 40 mA, 80 – 130 keV • 1 – 5 mm slice thickness Diagnostic CT • 40 – 335 mA, 80 – 130 keV • 0.33 – 2.0 mm slice thickness 2
