Brain Imaging01:14

Brain Imaging

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 Stimulation (TMS).

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Imaging Studies VII: Vascular Imaging

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...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

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.

Area of Science:

  • Neurology
  • Radiology
  • Obstetrics

Background:

  • Pregnancy alters physiology, potentially causing neurological problems.
  • Diagnosing and treating pregnant patients with neurological symptoms presents unique challenges.
  • Neuroimaging is frequently necessary for evaluating pregnant patients with neurologic complaints.

Purpose of the Study:

  • To review the risks of computed tomography (CT) and magnetic resonance imaging (MRI) for the embryo and fetus.
  • To discuss the safety of intravenous contrast agents used in neuroimaging during pregnancy.
  • To outline neurologic diseases and syndromes specifically associated with pregnancy.

Main Methods:

  • Literature review of neuroimaging in pregnancy.
  • Analysis of risks associated with CT and MRI.
  • Discussion of contrast agent safety.
  • Review of pregnancy-associated neurologic conditions.

Main Results:

  • CT and MRI carry potential risks to the embryo and fetus, influenced by radiation and magnetic fields.
  • Intravenous contrast administration requires careful consideration of fetal safety.
  • Specific neurologic conditions unique to pregnancy are identified and discussed.

Conclusions:

  • Neuroimaging decisions in pregnancy must balance maternal diagnostic needs with fetal safety.
  • Understanding the risks of CT, MRI, and contrast agents is crucial for clinical practice.
  • Knowledge of pregnancy-specific neurologic disorders aids in accurate diagnosis and management.
