Fig. 2From: Three-minute SPECT/CT is sufficient for the assessment of bone metastasis as add-on to planar bone scintigraphy: prospective head-to-head comparison to 11-min SPECT/CTIllustrative examples of the M1 category (bone metastases); in this example, tracer uptake was increased in the os sacrum and proximal right femur corresponding to osteosclerotic lesions on low-dose CT. Additionally, tracer uptake was increased in the left side of L3 and L5 corresponding to benign changes seen on low-dose CT. a Posterior view of a maximum intensity projection (MIP) from ultra-fast acquisition SPECT. b Posterior view of a MIP from standard acquisition SPECTBack to article page
