AIM: This pilot study made a preliminary attempt to distinguish different metabolic phenotypes of primary human brain tumors with dual tracer 13 N-ammonia and 18 F-FDG. METHODS: 74 patients were included in this study including 12 benign meningiomas (B-MEN), 4 malignant meningiomas (M-MEN), 15 low-grade gliomas (LGG), 32 high-grade gliomas (HGG) and 11 primary central nervous system lymphomas (PCNSL). All patients underwent 13 N-ammonia and 18 F-FDG PET imaging...

AIM: Thyroid hemiagenesis (TH) is a rare congenital anomaly in which one thyroid lobe fails to develop. We describe our experience with at least 13 patients presenting with TH at our department. METHODS: We retrospectively analysed patients with TH, who had been referred primarily to our clinic between 2004 and 2010. In patients with TH, thyroid function parameters and thyroid autoantibodies were examined. 99m Tc-pertechnetate thyroid scintigraphy and sonography were performed in all patients and confirmed the diagnosis of TH...

Combined PET/MR imaging (PET/MRI) was proposed for patient management in 2006 with first commercial versions of integrated whole-body systems becoming available as of 2010. PET/MRI followed the prior evolution of hybrid imaging as attested by the successful adoption of combined PET/CT and SPECT/CT since the early 2000 s. Today, around 150 whole-body PET/MRI systems have become operational worldwide. One of the main application fields of PET/MRI is oncologic imaging. Despite the increasing use of PET/MRI, little governance regarding standardized PET/MRI protocols has been provided to date...

AIM: Retrospective evaluation of serial FDG-PET/CT scans in head and neck squamous cell cancer (HNSCC) patient's follow-up after primary radiochemotherapy (RCTx), to assess the diagnostic accuracy of an experienced observer vs. an objective classification compared to standard clinical follow-up examinations. METHODS: Sixty-nine patients with locally advanced HNSCC were included, who received curative RCTx. Follow-up included serial FDG-PET/CT at the following time intervals t1: ≤ 270 d, t2: 271-540 d, t3: > 540 d after curative RCTx...

AIM: to evaluate the time trend of epidemiology of follicular cell derived thyroid cancer (TC) based on data from a well documented cancer registry. METHODS: Population based data on TC from Lower Franconia (LF), Germany, within 1981 and 2015 were analysed to estimate the regional epidemiology of TC. The incidence was assessed in 5-year-intervals for gender, histology, and tumor stage. RESULTS: Incidence of TC solely attributable to papillary TC (PTC) doubled mainly in T1- and T2-stages within the evaluation period from 4...

The aim of this paper is to highlight key aspects to be considered from a radiopharmaceutical point of view when performing prospective multicentre clinical trials using short-lived PSMA-PET-radiopharmaceuticals as investigational medicinal product (IMP). Early prospective multicentre clinical trials are playing an increasingly important role in nuclear medicine translational research; in order to be able to establish new PET tracers with a short physical half-life (e. g. for prostate cancer diagnostics) in the regulatory approval process, nuclear medicine centres are working together across multiple sites in order to be able to achieve the required number of patients to be included within the clinical study in a reasonable time frame...

AIM: The aim of this study was to establish normal values for parotid gland (PG) and submandibular-sublingual salivary gland complex (SSC) uptake of 99m technetium pertechnetate (99m TcO4 ) as a function of age, sex and circadian rhythm in mice. METHODS: In 12 female (F) and 12 male (M) C57BL/6N mice, nine consecutive SPECT images of 10 min each were acquired as dynamic acquisitions beginning 5 min after intravenous injection of 80 MBq 99m TcO4 . Each mouse was imaged in follow-up studies at 1, 3, 6, 12 and 24 months of age...

AIM: To prospectively evaluate histological significance and predictive value of changes in apparent diffusion coefficient (ADC) and 18 F-FDG PET/CT parameters in locally advanced rectal cancer (LARC) after neoadjuvant radiochemotherapy (RCT). METHODS: Twenty-one patients with untreated LARC underwent pre-RCT and post-RCT 18 F-FDG PET/CT and diffusion-weighted magnetic resonance imaging (DW-MRI), followed by surgery. For both datasets, two readers measured the tumor SUVmax, SUVmean, MTV, TLG, ADCmin, ADCmean, and respective differences (∆SUVmax, ∆SUVmean, ∆MTV, ∆TLG, ∆ADCmin, ∆ADCmean) for the whole tumor...

AIM: Here we describe the results of superselective intraarterial application of diagnostic Ga-68-DOTA0,Tyr3-octreotate (Ga-68-DOTATATE) in a series of patients with inoperable WHO grade II meningiomas which were no longer amenable to radiotherapy. METHODS: Four patients with inoperable WHO grade II meningioma underwent systemic venous infusion of Ga-68-DOTATATE followed by PET/CT. Ga-68-DOTATATE application was repeated intraarterially via transfemoral catheterization of vessels supplying the meningioma and another PET/CT was performed...

AIM: Cervical cancer is one of the most common cancers of the female reproductive system. The aim of the study was to assess the usefulness of the 18 F-FDG-PET/CT study in staging of cervical cancer, with focus on the primary tumor parameters. MATERIAL & METHODS: 105 patients (mean age 56 ± 11y) with newly diagnosed cervical cancer underwent PET/CT examination which was performed 60 min after IV injection of 18 F-FDG with a mean activity of 364 ± 75MBq...
