Our findings suggest that remnant thyroid tissue in patients with low-risk, well-differentiated thyroid cancer after total thyroidectomy can be ablated with 800 MBq of I-131. The success rate is not different from that obtained with 3700 MBq I-131.

Objective: In the process of PET/CT scanning, patients go through a general evaluation while their medical history is being taken, but it is often overlooked that these patients should be evaluated not only biologically but also bio psychosocially. Psychiatric symptom profiles and help-seeking behaviours of cancer patients were examined in this study. Methods: Cancer patients presented to nuclear medicine clinic filled out sociodemographic data form, psychiatric admission evaluation form, Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and Symptom Checklist-90 (SCL-90) form for psychiatric symptom screening. Results: In this study 27.8% of the patients had a Beck Depression score ≥18 and were in the risk group for depression, 31.7% of the patients experienced moderate or severe anxiety symptoms. Beck Depression Total and Beck Anxiety Total values were found significantly higher in women than in men. Only 10,2% of the cancer patients reported that they sought psychiatric help in the last 6 months. Among the patients who were risky for depression according to BDI only 25%  had been receiving psychiatric help and in among the patients who were risky for anxiety according to BAI only %26.9 had been receiving psychiatric help Conclusion: Nuclear Medicine physicians' interest in psychiatric symptoms and help-seeking behaviors of cancer patients referred to Nuclear Medicine Clinics is very important in terms of psycho-oncology.

Objective Positron emission tomography/computed tomography (PET/CT) imaging is used for many purposes such as diagnosis and staging of cancer patients and there may be different worries and opinions about this method. It is known patients may be anxious before PET/CT scan, but it is not well known whether their opinions continue after scanning. The aim of this study was to evaluate pre-and post-imaging worries and opinions of oncological patients referred to the Nuclear Medicine Clinic for PET/CT imaging. Materials and MethodsSociodemographic data form, STAI-I state, STAI-II trait anxiety forms, pre-test and post-test forms evaluating confidence-knowledge-worry about PET/CT procedure which is prepared by study team were applied to cancer patients referred to Nuclear Medicine Clinic.Results Confidence and worry were associated with gender, living place, well informed and being knowledgeable about the illness (p<0.05). In pre-test, it is observed that men relied PET/CT imaging more than women. However, there was no significant difference in post-test confidence scores. Before scanning, women were more worried than men. The worry scores of the patients living in rural areas both before PET/CT and after PET/CT procedure were higher than those living in urban areas and it was inversely correlated with knowledge and confidence Conclusion PET/CT procedure can be an alarming experience for patients. In this process, well informed and being knowledgeable is associated with lower worry and higher confidence. Making this process more reassuring can contribute to decreased worry.
