Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

627
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Imaging Studies for Cardiovascular System V: CT

581
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Adrenal Gland Disorders01:27

Adrenal Gland Disorders

3.9K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Area of Science:

  • Radiology
  • Oncology
  • Endocrinology

Background:

  • Adrenal glands are frequent sites for primary tumors and metastatic disease.
  • Accurate characterization of adrenal masses is crucial for patient management.
  • Various imaging modalities are employed for adrenal gland assessment.

Purpose of the Study:

  • To review the established morphologic criteria for assessing adrenal masses using CT and MR imaging.
  • To discuss the role of fluorine-18 fluorodeoxyglucose PET combined with CT in evaluating adrenal lesions.
  • To outline how imaging findings guide decisions regarding follow-up, biopsy, or resection of adrenal masses.

Main Methods:

  • Computed tomography (CT) and Magnetic Resonance (MR) imaging utilize established morphologic criteria.
  • Fluorine-18 fluorodeoxyglucose Positron Emission Tomography (PET) combined with CT is a key imaging modality.
  • Differentiation of benign from malignant adrenal masses is based on imaging characteristics.

Main Results:

  • CT and MR imaging provide criteria to assess adrenal mass nature (benign vs. malignant).
  • These modalities aid in determining the need for further intervention (follow-up, biopsy, resection).
  • In patients with known cancer, imaging helps distinguish benign adrenal masses from metastases.

Conclusions:

  • Established morphologic criteria on CT and MR imaging are vital for adrenal mass evaluation.
  • Integrated PET-CT enhances the diagnostic capability for adrenal lesions.
  • Imaging plays a critical role in guiding the management strategy for adrenal gland abnormalities.
