In the standard software for the Siemens HRRT PET scanner the most commonly used segmentation in the ??-map reconstruction for human brain scans is MAP-TR. Problems with bias in the lower cerebellum and pons in HRRT brain images have been reported. The main source of the problem is poor bone / soft tissue segmentation in these regions and the lack of scatter correction in the ??-map reconstruction...
In this paper, the resolution of the Siemens high resolution research tomograph (HRRT) was centrally (r < 60 mm) homogenous with a FWHM of 1.4 mm for 18F-FDG in air. This was where the main part of the brain is located if the patient has been positioned correctly. The 1.4 mm resolution was obtained using the newly develop 3D-OSEM PSF reconstruction algorithm, which was a significant improvement...
Relapse occurs in 30% of patients with stage I non-seminomatous germ cell tumours (NSGCT) within 1 year after orchiectomy. Whole-body positron emission tomography with fluorine-18 fluorodeoxyglucose (FDG-PET) may detect small metastases when standard staging with computed tomography (CT) and tumour markers is negative. In this study, 46 patients underwent FDG-PET after staging with normal CT and tumour...
