Positron emission tomography/computed tomography in platinum-sensitive recurrent ovarian cancer: A single-center italian study
No full textAim: To assess the correlation between contrast-enhanced computed tomography (CE-CT) and positron-emission tomography (PET)/CT results and surgical and pathological findings in patients with recurrent platinumsensitive ovarian cancer who underwent secondary cytoreduction. Patients and Methods: 18F-fluorodeoxyglucose (18F-FDG) PET/CT with/without CE-CT were performed before 56 cytoreductive surgeries in 49 patients with suspicious recurrent ovarian cancer. Results: 18F-FDG PET/CT showed higher sensitivity and diagnostic accuracy compared with CECT for both the whole series (100% versus 90.6%, respectively, and 97.8% versus 85.3%), and the 24 cases in which both examinations were performed (100% versus 87.0% and, respectively, 95.8% versus 83.3%). The addition of CE-CT to 18F-FDG PET/CT did not improve its diagnostic reliability. Conclusion: 18F-FDG PET/CT appears to be the more reliable imaging technique for the evaluation of patients with suspicious recurrent ovarian cancer, and for the selection of those more suitable for secondary cytoreductive surgery
Thyroid ultrasound and other imaging procedures in the pediatric age
No full textThe purpose of this review is to provide a reappraisal of the diagnostic imaging procedures for thyroid carcinoma in pediatric patients, including thyroid ultrasound (US), ultrasound-guided fine-needle aspiration biopsy (FNAB), scintigraphy, radiological techniques (CT, MR), and PET/CT. The most frequent indication for thyroid imaging is characterization of a palpable mass in the neck or thyroid gland. Thyroid US is a first-line examination for visualizing the thyroid gland as it provides anatomic and perfusion in-formation; on the other hand, scintigraphy mostly provides functional information but combined with some anatomic information as well. CT and MRI have a supplemental role in these patients. Furthermore, with the introduction of PET/CT and the development of new imaging agents, nuclear medicine plays an important role in different phases of neoplastic disease in terms of both staging and evaluation of response to medical/surgical treatments
