Multimodality Imaging of Neuroendocrine Tumors
Neuroendocrine tumors are rare solid tumors with an estimated 12,000 people in the United States diagnosed each year. Neuroendocrine tumors can occur in any part of the body. There is…
Neuroimaging of the Pituitary Gland
The pituitary gland is a small endocrine organ located within the sella turcica. Various pathologic conditions affect the pituitary gland and produce endocrinologic and neurologic abnormalities. The most common lesion…
Neuroendocrine Tumors
Neuroendocrine neoplasms are a heterogeneous group of tumors arising from cells distributed throughout the body. Local and regional disease is managed with surgical resection; however, treatment of higher-grade neuroendocrine tumors…
Molecular Imaging in the Head and Neck
This article is a summary of the most up-to-date applications of radiopharmaceuticals to the diagnosis and therapy of benign and malignant diseases involving endocrine or neuroendocrine organs of the head…
Neck Procedures: Thyroid and Parathyroid
Fine-needle aspiration (FNA) and core biopsy of masses in the neck predominantly include samples from thyroid nodules, parathyroids and lymph nodes. The diagnostic rate of a thyroid nodule FNA improves…
Imaging of Adrenal-Related Endocrine Disorders
Endocrine disorders associated with adrenal pathologies can be caused by insufficient adrenal gland function or excess hormone secretion. Excess hormone secretion may result from adrenal hyperplasia or hormone-secreting (ie, functioning)…
Parathyroid Imaging
Primary hyperparathyroidism (PHPT) is a common endocrine abnormality, caused in most cases by a single parathyroid adenoma. Surgery remains the first-line curative therapy in PHPT. Imaging plays a vital role…
Computed Tomography and MR Imaging of Thyroid Disease
Over the past several years, there has been an increase in the discovery of thyroid cancers, likely because of the marked increased utilization of computed tomography (CT) and MR imaging….
Ultrasound of the Normal Thyroid with Technical Pearls and Pitfalls
Ultrasound is the best imaging modality for comprehensive evaluation of the thyroid. The thyroid is best imaged using a high-frequency linear probe with the patient in a supine position with…
Thyroid Incidentalomas
Radiologists very frequently encounter incidental findings related to the thyroid gland. Given increases in imaging use over the past several decades, thyroid incidentalomas are increasingly encountered in clinical practice, and…
