Imaging Biological Samples with Optical Microscopy

4.8K
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

7.0K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Area of Science:

  • Neurology
  • Radiology
  • Medical Imaging

Background:

  • Endovascular treatment (EVT) for acute ischemic stroke requires specific imaging.
  • Current imaging protocols aim for efficient treatment triage and procedural strategy determination.
  • No single imaging technique is perfect; each has unique advantages and disadvantages.

Purpose of the Study:

  • To outline the minimal imaging requirements for EVT in acute ischemic stroke.
  • To discuss the importance of selecting imaging that quickly determines EVT candidacy and guides treatment.
  • To review common EVT imaging protocols and their limitations.

Main Methods:

  • Review of standard stroke imaging protocols for EVT triage.
  • Discussion of non-contrast CT (NCCT) with CT angiography (CTA), CT perfusion (CTP) with CTA, and MRI with MR angiography (MRA).
  • Consideration of dual-energy CT for post-EVT assessment.

Main Results:

  • NCCT and CTA is a common triage option, but may lack sufficient information.
  • CTP and CTA or MRI and MRA offer more comprehensive data but may be more time-consuming.
  • Dual-energy CT aids in differentiating post-EVT hemorrhage from contrast leakage.

Conclusions:

  • Optimal imaging for EVT selection balances information needs with time constraints.
  • The necessity of perfusion imaging or MRI within 6 hours of stroke onset remains an area for further investigation.
  • Efficient and accurate pre-EVT imaging is crucial for successful stroke intervention.
