The purpose of this review on SPECT/CT radiation dosimetry is to provide updated information on the total effective dose and total equivalent doses to critical organs due to both radiopharmaceutical administration and CT scan modality for both adults and pediatric patients. The use of new solid-...
The 3D X-Ray dose modulation option was activated and the acquisition covered the neck and the head with an average scan time of 3.2 s (range 2.7–3.6) and an average scan length of 34.1 cm (range 27.6–39.1). The average injection rate was 4.8 cc/s (range 2.9–5.8). The second (...
