The first day or injection day (D0), an early imaging session with planar acquisitions (anterior and posterior views) will be performed within 30 min post-tracer injection. A delayed imaging session with planar and SPECT/CT acquisitions will be also performed 1 to 3 hours after tracer injection. The SPECT/CT device to be used in this research protocol is the Infinia Hawkeye 4-slice from GE Healthcare. This hybrid camera incorporates a low-dose CT with a 2.5 mA current (eff.dose < 2mSv) on a dual-head gamma camera. SPECT/CT data will be analysed on the Xeleris 2.05v (Volumetrix for Hawkeye Oncology).
