CT and MRI of adrenal masses

From: Applied Radiology | Date: August 1, 2006| Author: Westphalen, Antonio Carlos A; Joe, Bonnie N | Copyright information

The incidentally discovered adrenal mass is a reasonably common finding that occurs in up to 1.9% of patients at computed tomography (CT).1 Both CT and magnetic resonance imaging (MRI) are excellent methods for visualizing and characterizing adrenal lesions. The selection of specific CT and MRI protocols (Tables 1 and 2) will allow for an accurate diagnosis of such masses in many instances, especially when the imaging findings can he correlated with clinical data. This article reviews the CT ...

Usefulness of Standardized Uptake Values for Distinguishing Adrenal Glands with Pheochromocytoma from Normal Adrenal Glands by Use of 6-^sup 18^F-Fluorodopamine PET
The Journal of Nuclear Medicine ; 6-^sup 18^F-Fluorodopamine (^sup 18^F-FDA) PET is a highly sensitive tool for the localization of pheochromocytoma (PHEO). The aim of this study was to establish cutoff values for pathologic and physiologic adrenal gland tracer uptake. Methods: ^sup 18^F-FDA PET with CT coregistration was performed

The American Surgeon ; Rectal carcinoids are slow-growing tumors. They metastasize when their size is more than 2 cm. Common sites of metastasis are the liver, lungs, and bones. Metastases to thyroid, pancreas, kidneys, adrenal glands, pituitary glands, posterior fossa, and spleen are very rare. We present the case of a

Medical Imaging ; CT uses x-ray radiation, which is a known carcinogen. However, since the introduction of CT more than 30 years ago, the incidence of cancer within the United States has remained stable while the mortality rate has declined. One of the many reasons for this decline has undoubtedly been the
