ABSTRACT In recent years, medical imaging with hybrid techniques has widely accepted and employed in clinical routine. PET/MRI offers significant advantages, including excellent contrast and resolution and reduced ionizing radiation, as compared to well-established PET/CT. Therefore, PET/MRI is a promising modality for oncologic imaging of some regions, such as brain, head and neck, liver and pelvis. This article set out to analyze clinical conditions that could benefit from PET/MRI imaging based on our caseload. The potential of PET/MRI to become […]

The authors report the case of a 70-year-old male patient with chronic lymphoid leukemia who presented subsequently a papillary carcinoma of the thyroid with metastases to regional lymph nodes. The patient was treated with surgical thyroidectomy with regional and cervical lymph node excision and radioiodine therapy (I-131). The protocolar control scintigraphy 4 days after the radioactive dose showed I-131 uptake in both axillae and even in the inguinal regions. PET/CT showed faint FDG-F-18 uptake in one lymph node of the […]

A 69-year-old Caucasian female was referred to the Imaging Department for investigation of fever of unknown origin (FUO), fatigue for seven months, and recent onset of atypical chest pain. Laboratory tests revealed elevation of serum C-reactive protein levels and erythrocyte sedimentation rate. Positron emission tomography with computed tomography fusion (PET-CT) with F18-fluorodeoxyglucose (FDG) was performed for the evaluation of FUO by excluding malignancy. The FDG images revealed markedly diffuse and circumferential increased uptake suggesting diffuse inflammatory process along the walls […]
