Brightness of the display is determined by the amplitude of the echo which in turn is determined by the difference in density of the 2 adjacent tissues. Real time scanning refers to the fact that the image is updated so frequently that motion of the tissues being scanned is detectable on the screen (e.g. echocardiography). Abdominal scanning, equine tendons, ocular examinations (higher frequency 5-7.5 mHz). Computed Tomography is also known as __________.

Animal is placed on a platform that moves by controlled increments through a circular aperture of a gantry that supports the X-ray tube and detectors. At each incremental position, the X-ray tube rotates quickly around the animal as it emits X-ray and, through the use of a computer, it converts the X-rays to a cross-sectional image of the slice. This process is used for imaging the __________.

Study Notes

Heat Therapy

  • Heat therapy uses hot packs, wet heat, electrically heated pads, hot water bottles, and dry heat infrared lamps
  • Effects of heat:
    • Analgesia
    • Reduction of muscle spasm
    • Vasodilation
    • Reduction of edema
    • Increased blood flow to the skin
    • Increased nutrients and antibodies
    • Increased metabolism
  • Indications:
    • General malaise
    • Post-trauma
    • Following surgery
    • Sprains and muscle stiffness
    • Colic
  • Contraindications:
    • Light sensitive conditions
    • Impaired sensation

Cold Therapy

  • Cold therapy uses cold water, ice, or cold compresses
  • Effects of cold:
    • Immediate vasoconstriction
    • Decrease in tissue temperature
    • Reduced tissue activity and oxygen requirement of local undamaged cells
    • Increased circulatory flow in deep arteries adjacent to the area of damage
  • Techniques:
    • Running stream
    • Whirlpool tubs
    • Hosing
    • Cold bandaging
  • Indications:
    • Fillings in legs and joints
    • Local edema
    • Hematoma formation
  • Contraindications:
    • Open wounds
    • Fractures
    • Areas with nerve involvement (sensory or motor)

Diagnostic Imaging

  • Endoscopy:
    • Laryngoscopy and bronchoscopy for upper airway obstructions
    • Gastrointestinal endoscopy for visualizing mucosal surfaces of esophagus, stomach, and colon
  • Radiology:
    • Uses X-rays to produce images of internal structures
    • Contrast agents used to highlight certain areas
  • Ultrasonography:
    • Uses high-frequency sound waves to produce images of internal structures
    • Non-invasive and painless
  • Computed Tomography (CT):
    • Uses X-rays and computer algorithms to produce detailed cross-sectional images of internal structures

Alternative Therapies

  • Iridology:
    • Studies the iris to diagnose health conditions
    • Discolorations or marks in the iris indicate abnormal conditions in the body
  • Ayurveda Philosophy:
    • Three dynamic forces (doshas): Vata, Pitta, and Kapha
    • Tongue diagnosis: different areas of the tongue correspond to different organs of the body
    • Pulse diagnosis: determines the functioning and health of the mind-body constitution
    • Facial diagnosis: indicates disorders and diseases on the face in the form of lines, wrinkles, etc.
