Summary
This study reviews imaging techniques like CT, MR, and PET/CT for characterizing adrenal masses. Key features help differentiate benign adrenal tumors from malignant ones.
Area of Science:
- Radiology
- Medical Imaging
- Oncology
Background:
- Adrenal masses are common findings, requiring accurate characterization to guide management.
- Distinguishing benign from malignant adrenal lesions is crucial for patient outcomes.
- Multimodality imaging plays a key role in the diagnostic pathway.
Purpose of the Study:
- To provide a comprehensive overview of multimodality imaging for adrenal masses.
- To highlight the utility and limitations of computed tomography (CT), MR imaging, and PET/CT.
- To detail imaging features aiding in the differentiation of adrenal lesions.
Main Methods:
- Review of computed tomography (CT) characteristics including washout kinetics.
- Analysis of MR imaging features, focusing on fat content (macroscopic and microscopic).
- Evaluation of positron emission tomography/computed tomography (PET/CT) for metabolic activity assessment.
Main Results:
- Specific imaging features like fat content and CT washout kinetics are vital.
- Metabolic activity on PET/CT can indicate malignancy.
- Combined imaging modalities improve diagnostic accuracy for adrenal masses.
Conclusions:
- Multimodality imaging provides a robust framework for adrenal mass characterization.
- Understanding the strengths and limitations of CT, MR, and PET/CT is essential.
- Accurate differentiation of benign (adenomas, myelolipomas) from malignant (adrenocortical carcinoma, metastases) adrenal lesions is achievable.

Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
Imaging Studies III: Computed Tomography
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
