(up) Transaxial view images of a 49-year-old woman (BMI = 17.2) with metastatic colon adenocarcinoma confirmed by aspiration biopsy (m–r) for OSEM3 (m), OSEM2 (n), HYPER0.3 (o), HYPER0.4 (p), HYPER0.5 (q), and HYPER0.6 (r). The white arrows show avid FDG of the right hepatic lobe more remarkable in the HYPER reconstructions compared with OSEM reconstructions. (down) A 67-year-old woman (BMI = 30.7) with Hepatic metastasis of breast carcinoma. The FDG avid lesions were shown on the liver parenchyma in the transaxial view for the group OSEM3 (s), OSEM2 (t), HYPER0.3 (u), HYPER0.4 (v), HYPER0.5 (w) and HYPER0.6 (x). There was equal or decreased diagnostic confidence of lesion detectability (indicated by black arrows) in HYPER reconstructions compared with OSEM3(s)
