It is associated with higher aggressiveness of the tumour and a reduced 10-year survival rate. The diagnosis of non-radioiodine avid DTC metastases remains a diagnostic challenge. A helpful technique for this diagnosis is positron emission tomography with 2-[¹⁸F]fluoro-2-deoxy-D-glucose (PET/CT with [¹⁸F]FDG). On the other hand, there are still discussions about the clinical value of using exogenous thyroid-stimulating hormone (TSH) stimulation before PET/CT with [¹⁸F]FDG. The aim of the study was the assessment of the usefulness of PET/CT with [¹⁸F]FDG under TSH suppression and stimulation of TSH performed in the detection of non-radioiodine avid DTC metastases, as well as determination of the thyroglobulin concentration under suppression and stimulation of TSH, which influences the result of PET/CT with [¹⁸F]FDG in patients with non-radioiodine avid DTC.</p><p><strong>Material and methods: </strong>Retrospective analysis of 37 PET/CT with [¹⁸F]FDG performed in patients with DTC diagnosed and treated at the Department of Endocrinology and Isotope Therapy of the Military Institute of Medicine from January 2018 to July 2020. Of these, PET/CT with [¹⁸F]FDG under exogenous rhTSH stimulation was performed in 22 patients and PET/CT with [¹⁸F]FDG under TSH suppression in 15 was performed. In all analyzed patients, the result of diagnostic whole-body scintigraphy (WBS) using 80 MBq ¹³¹I under rhTSH stimulation was negative, and the concentration of thyroglobulin after stimulation (sTg) was greater than 1.0 ng/mL.</p><p><strong>Results: </strong>In the group of patients examined under TSH suppression, non-radioiodine avid in PET/CT with [¹⁸F]FDG were found in 6 out of 15 patients (40%) and in the group of patients examined under rhTSH stimulation in 10 out of 22 patients (45%). The differences between the groups were not statistically significant. The analysis of the receiver operating characteristic (ROC) curves allowed to determine the cut-off point for the positive result of PET/CT performed under TSH suppression with sTg concentration of 11.03 ng/mL. In the group of studies performed under rhTSH stimulation, the cut-off point for sTg was 6.3 ng/mL. There was no statistically significant difference between the baseline thyroglobulin (natTg) and sTg levels and the positive PET/CT result.

The described in literature longest interval between primary reconstruction and aortic graft infections was 20 years [1]. This research reports a case of a 60-year-old man with a suspected infection of an aortobifemoral bypass graft implanted 20 years ago due to an aneurysm of the abdominal aorta. He was referred to a nuclear medicine department for scintigraphic detection or exclusion of active infection within the stent-graft. The patient had many comorbidities: renal failure, arterial hypertension, hypertensive cardiomyopathy, ischemic heart disease. This year, the patient underwent thrombosis of the left saphenous vein with cellulitis of the left leg and was treated surgically due to an abscess of the left buttock. Laboratory tests revealed: leukocytosis, significantly elevated CRP and anaemia. Enterococcus faecalis susceptible to ampicillin, teicoplanin and vancomycin were grown on venous blood cultures. Despite the implementation of antibiotic therapy, no significant improvement in the patient’s clinical condition was achieved. The computed tomography examination showed changes suggesting infection of the vascular prosthesis. Due to the high risk of the surgery, it was decided to operate after obtaining scintigraphic detection of infection within the stentgraft. The examination was performed with Technetium-99m labelled leukocytes using HMPAO. The patient was examined 1, 4 and 24 hours after radiotracer injection using Symbia Intevo with a protocol including SPECT/CT with LEHR collimator, low-dose CT.","PeriodicalId":44718,"journal":{"name":"NUCLEAR MEDICINE REVIEW","volume":"24 2","pages":"115-117"},"PeriodicalIF":0.9,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39313949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
