Rad CH.1

Ultrasonographic imaging of the heart and associated vasculature.

• Computerized Tomography

• Magnetic Resonance Imaging

• Sonography

• Echocardiography

Answer explanation

Echocardiography

↓

Cardio

↓

Heart/Exercise

-Recording of a predetermined plane in the body using an x-ray beam that is measured, recorded, and then processed by a computer for display on a monitor.

-Uses x-ray energy and sophisticated software to create sectional images of the human body.

-Acquires hundreds of views of patient anatomy, as the x-ray tube and CT detector rotate around the patient.

-Ionizing

what is this describing?​ (a)  

• Computed Tomography (CT)
• Magnetic Resonance Imaging (MRI_
• Vascular Interventional Radiography (VI)

Answer explanation

CT sounds like for ‘CUT’—it slices your body into sectional images

Computerized -> Software

Computer -> Charged -> Ionized

When did Wilhelm Röntgen discover x-rays?

• 1924

• 1913

• 1895

• 1845

Answer explanation

He discovered X-rays sometime in 1895

The first X-ray was taken November 8 1895

Any process by which a neutral atom gains or loses an electron, thus acquiring a net charge is​ (a)  

• Ionization
• Radiation
• Polarization 
• Spaghettification 

Answer explanation

Mnemonic Device:

Think of ION as ‘I’m ON’—an atom switches ON its charge by gaining or losing electrons (getting ionized)

Organize these options into the right categories

Groups:

(a) Non-Ionizing

,

(b) Ionizing

• CT (Computed Tomography)

• Radiation Therapy

• Diagnostic Medical Sonography (Ultrasound)

• MRI (Magnetic Resonance Imaging)

• X-Ray

• Positron Emission Tomography (PET)

• Mammography

​ (a)   is the creation of sectional images of the body that demonstrate the physiologic function of various organs and systems

• Positron Emission Tomography (PET)
• Magnetic Resonance Imaging (MRI)
• Ultrasound Imaging
• X-ray Radiography

Answer explanation

Mnemonic Device:

PET to the VET - pets can’t communicate so you take it to the vet to test it’s physiological function

Positron -> Charged -> Ionizing

The study of diseases of muscles and bones is ​​ (a)   ?

• orthopedics
• cardiology
• neurology
• dermatology

Match the following

• Radiologist

• Physician who specializes in the use of x-rays and other forms of both ionizing and nonionizing radiation in the diagnosis and treatment of disease.

• Radiologist Assistant (R.A.)

• An advanced-level radiographer who extends the capacity of the radiologist in the diagnostic imaging environment, thereby enhancing patient care.

• Radiologic Technologist (R.T.)

• General term applied to an individual who performs radiography, radiation therapy, or nuclear medicine technology.

Energy transmitted by waves through space or through a medium.

• Absorption

• Radiation

• Gamma Radiation

• Radiowaves

Answer explanation

Mnemonic Device:

“Picture radio signals transmitting through the air and walls of your home—Radiation!”

Select what is true about :

Cardiac Interventional Radiography

• Radiologic procedures for the diagnosis and treatment of diseases of the cardiovascular system.

• Uses x-rays to visualize human blood vessels and heart anatomy.

• Requires the use of a catheter and the injection of x-ray contrast material to visualize anatomy.

• Uses high-frequency sound energy to create medical images.

• Process of using a magnetic field and radio frequencies to create sectional images of the body.

Answer explanation

Cardiovascular
