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...

Anatomy of the Brain: Ventricles

8.9K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

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...

Brain Waves

4.1K
Brain waves are electrical signals generated by the neurons in the brain, which are regularly monitored to measure mental activities. Brain waves and their frequency ranges can be measured using an electroencephalogram or EEG. There are four main types of brain waves, each with distinct characteristics:

Organization of the Brain

2.7K
The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Summary

Diffusion-weighted imaging (DWI) is a key tool for diagnosing brain diseases like infarctions. This review covers advanced techniques such as diffusion-tensor imaging (DTI) and fiber tracking, expanding on DWI capabilities.

Area of Science:

  • Neuroimaging
  • Radiology
  • Medical Physics

Context:

  • Diffusion-weighted imaging (DWI) is a standard clinical technique.
  • DWI is crucial for evaluating brain pathologies, particularly ischemic strokes.
  • Advanced DWI techniques offer enhanced diagnostic information.

Purpose:

  • To review technical advancements in diffusion imaging of the brain.
  • To explain diffusion-tensor imaging (DTI) and fiber tracking as extensions of DWI.
  • To highlight the clinical applications of these neuroimaging methods.

Summary:

  • This review focuses on diffusion-weighted imaging (DWI), a vital neuroimaging modality.
  • It details diffusion-tensor imaging (DTI) and fiber tracking, which build upon DWI principles.
