Imaging Studies II: Positron Emission Tomography and Scintigraphy

668
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Brain Imaging

787
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Positron Emission Tomography01:29

Positron Emission Tomography

7.8K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

529
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...

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...

The Pituitary Gland01:17

The Pituitary Gland

11.3K
The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.

Area of Science:

  • Radiology
  • Medical Imaging
  • Endocrinology

Background:

  • Historically, diagnosing pituitary masses relied on indirect signs from plain radiography, pneumoencephalography, and angiography.
  • Computed tomography (CT) and Magnetic Resonance Imaging (MRI) have revolutionized pituitary lesion visualization.

Purpose of the Study:

  • To review the evolution and current roles of imaging modalities in diagnosing pituitary masses.
  • To highlight the complementary utility of CT and MRI in pituitary imaging.

Main Methods:

  • Review of historical and current imaging techniques for pituitary pathology.
  • Comparison of diagnostic capabilities of plain radiography, angiography, CT, and MRI.

Main Results:

  • MRI is the preferred modality for delineating pituitary lesions.
  • CT provides superior bone detail and calcification detection, crucial in select cases.
  • Older techniques are largely superseded by CT and MRI.

Conclusions:

  • MRI is the gold standard for pituitary imaging.
  • CT remains valuable for assessing bony structures and calcifications associated with pituitary masses.
  • A combination of imaging modalities may be necessary for comprehensive pituitary mass evaluation.
