Extended staging of Oesophageal cancer using FDG-PET . A critical appraisal
Review of the accuracy of FDG.PET in the staging of esophageal cance
Evolving paradigms for successful molecular imaging of medullary thyroid carcinoma.
The principals methodologies to investigate meduallry thyroid carcinoma are described in detail
Imaging identifies submanibular ectopic thyroid tissue
The identification of submandibular ectopic normal thyroid in the lateral neck with a coexisting normally located and functional thyroid gland is rare. Ectopic normal thyroid tissue in the midline location is most commonly related to aberrant migration along the thyroglossal duct (ie, lingual thyroid). A 54-year-old man with a 6-month history of visible asymptomatic swelling in the right submandibular region had ultrasonography and Tc-99m pertechnetate imaging
How has the management of medullary thyroid carcinoma changed with the advent of 18F-FDG and non-18F-FDG PET radiopharmaceuticals
Comparison between anatomical cross-sectional imaging and 18F-FDG PET/CT in the staging, restaging, treatment response, and long-term surveillance of squamous cell head and neck cancer: a systematic literature overview
Surgical therapeutic planning options in nodular goiter
Abstract: Nodular goiter encompasses a spectrum of diseases from the incidental asyntomatic small solitary nodule to the large intrathoracic goiter causing pressure symptoms as well as functional complaints. The mainstay in the diagnostic evaluation is related to functional and morphological characterization with serum thyroid-stimulating hormone (TSH), ultrasound (US) and other imaging procedures and cytology by fine needle aspiration (FNA) on the basis of the different diseases. A clinical classification considering solitary cyst, adenomatous functioning nodule, follicular lesion and multinodular goiter may be proposed to consider the alternative therapies other than surgery as TSH suppressive or thyrostatic treatment, (131)I therapy, percutaneous ethanol injection therapy (PEIT) or the only clinical exam in benignant lesions. Surgery should be advocated for the treatment of thyroid nodules whenever a patient presents with either pressure symptoms, hyperthyroidism or follicular/indeterminate cytology. Surgical approach, intraoperatory strategy and the extension of surgical treatment are correlated to the different clinical categories. At surgery the frozen section analysis in case of hemithyroidectomy is of aid to rule out malignancy and to prevent the reoperation. The surgical treatment of choice in case of uninodular goiter is lobectomy, total thyroidectomy or near total thyroidectomy is the correct treatment of multinodular bilateral goiter. The choice of the treatment must be condivided with the patient
Comparative studies of radiolabeled choline positron emission tomography, histology of primary tumor and other imaging modalities in prostate cancer: a systematic review and meta-analysis
Imaging identifieds submanidibular ectopic thyroid tissue
Abstract: The identification of submandibular ectopic normal thyroid in the lateral neck with a coexisting normally located and functional thyroid gland is rare. Ectopic normal thyroid tissue in the midline location is most commonly related to aberrant migration along the thyroglossal duct (ie, lingual thyroid). A 54-year-old man with a 6-month history of visible asymptomatic swelling in the right submandibular region had ultrasonography and Tc-99m pertechnetate imaging
18F-DOPA PET/CT in the evaluation of hereditary paraganglioma-pheochromocytoma syndromes
Non invasive parathyroid imaging in primary hyperparathyroidism
Several studies suggested that preoperative localization of abnormal parathyroid (PT) glands may be useful in reducing operative time facilitating parathyroidectomy, especially in patients with ectopic PT glands. At present, noninvasive techniques used to evaluate patients with primary HPT include (1) 99mTc-sestamibi scintigraphy, (2) high-resolution neck ultrasonography, (3) CT scanning, and (4) magnetic resonance imaging (MRI). The sensitivity and positive predictive value of each technique range from 70% to 90%, and a combination of two of more tests may significantly improve the results. In the minimally-invasive era both radioguided and video-assisted parathyroidectomy require an accurate preoperative localization of the abnormal PT glands, and PT imaging should be obtained before surgery in all patients with primary hyperparathyroidism, with the aim of reducing operative time and hospital stay
