Study Notes
Microscopy
- Microscopy is the process of using a microscope to examine small structures.
- Light microscopy uses a beam of light and provides lower magnification.
- Electron microscopy utilizes electrons for higher magnification.
Preparing Tissue for Microscopy
- Fixation preserves specimens.
- Sectioning cuts specimens into thin slices.
- Acidic stains, negatively charged, bind to positive cellular components.
- Basic stains, positively charged, bind to negative cellular components.
Types of Electron Microscopy
- Scanning Electron Microscopy (SEM) provides 3D images of entire surfaces.
- Transmission Electron Microscopy (TEM) displays inner structures like crystal morphology.
- Artifacts are minor distortions in preserved tissues that do not represent living tissues.
Radiographic Anatomy
- Radiographic anatomy studies anatomy using imaging techniques like X-rays, CT scans, and MRIs.
- It's important for non-invasive visualization in clinical practice.
Clinical Anatomy—Medical Imaging Techniques
- Key medical imaging techniques include X-Ray Images, Computed Tomography (CT), Angiography, Positron Emission Tomography (PET), Sonography (Ultrasound), and Magnetic Resonance Imaging (MRI).
X-Ray Images
- X-Ray Images uses utilizes electromagnetic waves of very short length.
- X-Rays are most effective for visualizing bones and abnormal dense structures.
Computed Tomography (CT)
- Computed Tomography (CT), also known as axial tomography.
- CT generates detailed body section images using successive X-rays around the circumference of the patient.
Digital Subtraction Angiography (DSA)
- Angiography highlights vascular structures using contrast mediums.
- DSA captures images before and after contrast injection.
- A computer analyzes the images to identify blockages in arteries.
Positron Emission Tomography (PET)
- Positron Emission Tomography (PET) creates images by detecting radioactive isotopes administered into the body.
Ultrasound Imaging (Sonography)
- Ultrasound Imaging (Sonography) uses high-frequency sound waves that echo off body tissues.
- Primarily used for determining the age of a developing fetus.
Magnetic Resonance Imaging (MRI)
- Magnetic Resonance Imaging (MRI) produces high-contrast images focused on soft tissues.
- MRI allows differentiation of body structures based on water content.
