    Study Notes

    Radiologic Modalities

    • Radiology modalities are used to identify medical conditions like bone fractures, cancers, and cardiovascular disease.
    • Radiology modalities offer a wide range of images for radiologists to examine.

    Ultrasound

    • Ultrasound uses soundwaves to create images of the body's organs, tissues, and structures.
    • Ultrasound gel is made of water and propylene glycol.
    • Ultrasound is also called ultrasonography or sonography.
    • Ultrasound uses sound waves instead of radiation, making it safe for its user.
    • Ultrasound is non-invasive.

    X-Ray

    • X-rays are used to create images of internal structures, such as bones and organs.
    • X-rays help diagnose fractures, infections, and diseases like pneumonia.
    • X-ray scanners are used to inspect luggage and cargo for security threats.
    • X-ray telescopes are used to observe celestial objects and phenomena, such as black holes, neutron stars, and supernovae.
    • X-ray fluoroscopy provides real-time imaging, useful for surgeries and procedures.
    • X-ray equipment is available in most hospitals, clinics, and dental offices.
    • X-rays are a fast and accurate diagnostic tool, especially in emergency situations.
    • X-rays can be used to inspect materials and products without causing damage.

    Mammography

    • Mammography uses low-dose X-rays to examine the breast.
    • Mammography's primary use is in breast health and cancer screening.
    • Mammography is used to detect early signs of breast cancer in asymptomatic women.
    • Diagnostic mammograms help evaluate breast tissue and guide further investigation.
    • Mammograms can monitor changes in breast conditions like cysts or calcifications over time.
    • Mammograms can identify small tumors that may not be felt during a physical breast exam.

    Magnetic Resonance Imaging (MRI)

    • MRI uses strong magnetic fields and radio waves to create detailed images of internal structures.
    • MRI is commonly used to examine the brain and spinal cord for conditions such as tumors, stroke, and multiple sclerosis.
    • MRI helps assess injuries to muscles, ligaments, and joints, including tears and fractures.
    • MRI can evaluate heart structures, function, and blood flow, useful in diagnosing heart diseases.
    • MRI provides detailed images of soft tissues.
    • MRI can be used for various conditions and body parts.
    • MRI allows for the assessment of physiological processes.

    Computed Tomography (CT)

    • CT scans use X-rays to create detailed 3D images of internal structures.
    • CT scans help guide surgeons during procedures such as biopsies or planning surgeries.
    • CT scans detect internal bleeding, brain injuries, and other conditions after trauma.
    • CT scans help identify the cause of abdominal pain.
    • CT scans locate tumors, assess their size, and stage cancers.
    • CT scans monitor how cancer responds to treatment.
    • CT scans provide detailed 3D images of the body.
    • CT scans are a very accurate tool for detecting abnormalities.

    Fluoroscopy

    • Fluoroscopy uses continuous X-rays to create real-time, moving images of internal structures.
    • Fluoroscopy is used to guide a variety of procedures, such as catheter insertion, stent placement, or biopsy.
    • Fluoroscopy can visualize blood vessels and conditions like blockages or aneurysms.
    • Fluoroscopy assists in fracture repair, spinal surgeries, and joint replacement procedures.
    • Fluoroscopy provides quick and efficient results.
    • Fluoroscopy can be used in various medical fields, including cardiology, gastroenterology, orthopedics, and urology.
