Context: Reoperative surgery is the most efficient treatment of cervical persistent thyroid carcinoma. The extent of the surgery should be guided by the preoperative imaging findings, the primary surgery and the patient’s prognosis. However, there is no consensus concerning the optimal surgical strategy.Objective: Primary objective was to evaluate morbidity of a reoperative surgery. Secondary objectives were to evaluate performances of preoperative ...

Introduction: The management of large non secreting adrenal tumors (at least 4 cm) is still a matter of debate as it is unclear whether imaging, especially 18F-FDG, can be used to characterize their potential malignancy. Moreover, the risk of new hypersecretion in non-operated tumors is uncertain. Our aim was to better characterize these large adrenal incidentalomas.Methods: Patients followed in our Center for a non-secreting large (at least 4 cm) adrena...

Purpose: Persistence of well-differentiated thyroid carcinoma most commonly involves cervical lymph nodes. The purposes of the study were to evaluate the ability of FDG-PET/CT imaging to localize residual disease in initial stage M0 thyroid carcinoma thyroid cancer patients and to compare FDG-PET/CT to neck US.Methods: FDG-PET/CT and neck US results of 93 patients were retrospectively analysed. All FDG-PET/CT were performed during thyrotropin stimulation...

Background: Recombinant human TSH (rhTSH) has become the modality of choice for radioiodine remnant ablation of residual thyroid cancer tissue in low-risk patients.Methods: The FACIT-F was administered from the early postoperative period to 9 months. Socio-demographic parameters, anxiety and depression scales were also evaluated. At 24 h, 48 h and d6 post-therapy, dose rate were measured. Using a simplified model, radiation exposure to public was estimat...

Purpose: The widespread use of high resolution cross-sectional imaging such as computer tomography (CT) and magnetic resonance imaging (MRI) for the investigation of the abdomen is associated with an increasing detection of incidental adrenal masses. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) has proved to be an efficient tool in the diagnosis and follow-up of malignancies. We evaluated the ability of FDG-PET to distinguish benign from malignant adrenal mass...

Background: Pheochromocytoma (PHEO) is a rare neuroendocrine tumor arising from chromaffin cells of adrenal gland that can cause life-threatening complications due to overproduction of catecholamines. Per EANM/SNMMI 2019 guidelines for radionuclide imaging of PHEO and paraganglioma, 18F-fluoro-L-dihydroxyphenylalanine (18F-FDOPA) is recommended as a positron emission tomography (PET) radiotracer of choice followed by 68Ga-DOTA(0)-Tyr(3)-octreot...

Background: The purpose of this prospective study was to evaluate and compare the detection rates of 18F-L-dihydroxyphenylalanine (18F-FDOPA), 68Ga-DOTATATE, 18F-FDG, and 18F-fluorodopamine (18F-FDA) PET or positron emission tomography/computed tomography (PET/CT), computed tomography (CT), and magnetic resonance imaging (MRI) in the detection of VHL-related pheochromocytoma (PHEO).<p class="abstext...

Background: To evaluate and compare the diagnostic performance of 68Ga-DOTATATE PET/CT to 18F-FDG PET/CT, CT of neck, chest, abdomen and pelvis (CT), and MRI of cervical, thoracic, and lumbar spine (MRI spine), for the detection of spinal bone metastases in metastatic pheochromocytoma and/or paraganglioma (PPGL).Methods: Between 2014 and 2019, 41 consecutive metastatic PPGL patients (19 females; mean age, 43 years) underwent 68...
