Medical Imaging

In medical imaging, a variety of imaging technologies are used to examine the human body to diagnose, monitor, or treat health conditions. Each technology provides a different level of insight into the body part that is being studied or treated. The insight pertains to disease, injury, or the results of medical treatment.

With this quiz, you will learn the different kinds of medical imaging equipment, their purposes, and how they perform medical procedures.

  • Question of

    The process of using X-rays to examine the human breast for diagnosis and screening.

    • Mammography
    • Projectional radiography
    • Single-photon emission computed tomography (SPECT)
    • Ultrasound

    Correct Wrong

    Mammography is the process of examining the human breast using low-energy X-rays for diagnostic purposes. Mammography aims to detect breast cancer early. Mammographies are projection radiographies of the breasts.

  • Question of

    The use of high-energy sound waves to look at organs and tissues in the body.

    • Ultrasound
    • Projectional radiography
    • Mammography
    • Echocardiography

    Correct Wrong

    Ultrasound utilizes high-energy sound waves to examine tissues and organs inside the body.

  • Question of

    Sectioning and imaging by using a penetrating wave.

    • Tomography
    • Projectional radiography
    • Fluoroscopy
    • Medical imaging

    Correct Wrong

    In tomography, sections are scanned using penetrating waves. A tomograph is a device used in tomography, while a tomogram is the image it produces.

  • Question of

    Also known as a gamma scan.

    • Scintigraphy
    • Mammography
    • Computed tomography (CT) scan
    • Echocardiography

    Correct Wrong

    Scintigraphy, or gamma scanning, generates images when radioisotopes attached to drugs are taken into an organ or tissue, and the gamma radiation they emit is captured by external detectors to produce two-dimensional pictures.

  • Question of

    The use of X-rays to obtain a moving image of an object’s interior in real-time.

    • Fluoroscopy
    • Ultrasound
    • Computed tomography (CT) scan
    • Elastography

    Correct Wrong

    In fluoroscopy, X-rays are used to obtain real-time images of the interior of an object. The fluoroscopy procedure permits a physician to observe the internal structure and function of a patient; for example, the heart's pumping action or the swallowing motion can be observed.

  • Question of

    The technique and process of creating visual representations of the interior of a body.

    • Medical imaging
    • Nuclear medicine
    • Computed tomography (CT) scan
    • Fluoroscopy

    Correct Wrong

    In medical imaging, visual representations of some organs or tissues (physiology) are made for the purpose of clinical analysis and medical intervention.

  • Question of

    The use of imaging technology for diagnosing and treating disease.

    • Radiology
    • Mammography
    • Tomography
    • Echocardiography

    Correct Wrong

    Imaging technology is used in radiology to diagnose and treat disease. The two areas of radiology are diagnostic radiology and interventional radiology. Physicians who specialize in radiology are called radiologists.

  • Question of

    Also called Plain X-Ray.

    • Projectional radiography
    • Echocardiography
    • Tomography
    • Positron emission tomography

    Correct Wrong

    Radiation produced by x-rays produces two-dimensional images by projectional radiography, which is also known as conventional radiography. The term "plain radiography" generally refers to projection radiography (without the use of more advanced techniques such as computed tomography).

  • Question of

    An imaging test using powerful magnets and radio waves.

    • Magnetic resonance imaging (MRI) scan
    • Elastography
    • Positron emission tomography
    • Projectional radiography

    Correct Wrong

    The magnetic resonance imaging (MRI) scan creates images of the body using powerful magnets and radio waves. No ionizing radiation is used (x-rays). MRI images are divided into slices. A single exam can produce dozens or even hundreds of images.

  • Question of

    A medical specialty involving the application of radioactive substances.

    • Nuclear medicine
    • Mammography
    • Ultrasound
    • Single-photon emission computed tomography (SPECT)

    Correct Wrong

    Radioactive tracers are used in nuclear medicine to diagnose and treat diseases and assess bodily functions. Imaging techniques are heavily used in nuclear medicine diagnosis. In nuclear medicine, single photon emission computed tomography and positron emission tomography are the two most common imaging modalities.

  • Question of

    Nuclear medicine tomographic imaging using gamma rays.

    • Single-photon emission computed tomography (SPECT)
    • Echocardiography
    • Mammography
    • Fluoroscopy

    Correct Wrong

    Single-photon emission computed tomography (SPECT, or SPET less commonly) is a nuclear medicine imaging technique using gamma rays. The use of SPECT can complement any gamma imaging study, where a true 3D representation can be beneficial, such as tumor imaging, infection (leukocyte) imaging, thyroid imaging, or bone imaging.

  • Question of

    A nuclear medicine tomographic imaging technique scan that shows how organs and tissues are working.

    • Positron emission tomography
    • Scintigraphy
    • Ultrasound
    • Projectional radiography

    Correct Wrong

    An organ or tissue's function can be seen with positron emission tomography (PET), a nuclear medicine imaging technique. It differs from MRIs and CT scan. These tests reveal the structure of the organs as well as the blood flow to and from them. PET/CT machines, which combine the images of PET and CT, are commonly used.

  • Question of

    This form of medical imaging maps the elastic properties and stiffness of soft tissue.

    • Elastography
    • Echocardiography
    • Magnetic resonance imaging (MRI) scan
    • Scintigraphy

    Correct Wrong

    A medical imaging modality called elastography measures the elastic properties and stiffness of soft tissue. A low-frequency vibration is used to perform elastography during an ultrasound or MRI. A fatty liver disease (FLD) and fibrosis can be diagnosed with elastography

  • Question of

    Imaging tool that uses x-rays and computer technology to produce a more detailed cross-sectional image of your body.

    • Computed tomography (CT) scan
    • Fluoroscopy
    • Elastography
    • Magnetic resonance imaging (MRI) scan

    Correct Wrong

    In computed tomography (CT) scans, x-rays are combined with computer-processed combinations to produce cross-sectional images of the body. The technology has become an essential tool in medical imaging as a complement to X-rays and medical ultrasonography.

  • Question of

    An ultrasound of the heart, uses standard two-dimensional, three-dimensional, and Doppler ultrasound to create images of the heart.

    • Echocardiography
    • Positron emission tomography
    • Tomography
    • Mammography

    Correct Wrong

    A heart ultrasound is called an echocardiogram. Heart images can be taken using two-dimensional, three-dimensional, or Doppler ultrasound. Patients with suspected or known heart diseases are routinely diagnosed, managed, and followed up using it.
