Question 1

Of the following body substances, which one is most radiolucent?

Accepted Answer

Air is the most radiolucent substance as it allows the most x-rays to pass through, appearing black or dark on a radiograph.

Question 2

The use of high frequency sound waves to visualize soft tissue structures in the body functioning in real time is called a(n)

Accepted Answer

The use of high frequency sound waves to visualize soft tissue structures in the body functioning in real time is called an ultrasound. CT scans use X-rays, MRI uses magnetic fields and radio waves, teleradiology refers to transmitting medical images electronically, and interventional radiology involves using medical imaging to guide minimally invasive surgical procedures.

Question 3

The term that refers to the use of a minimally invasive procedure for both diagnostic purposes and for treatment is

Accepted Answer

The term that best fits the description of using minimally invasive procedures for both diagnosis and treatment is interventional radiology. This involves the use of imaging guidance such as fluoroscopy or ultrasound to perform procedures such as biopsies, angioplasties, or the placement of catheters or stents. Teleradiology, digital radiography, and ultrasound may be used in the course of interventional radiology procedures, but they are not specific to this type of diagnostic and treatment approach.

Question 4

The vertical plane that divides the body into right and left portions is the ________ plane.

Accepted Answer

The answer of The vertical plane that divides the body...

Question 5

The person who operates ultrasound imaging devices to produce diagnostic images is a

Accepted Answer

A person who operates ultrasound imaging devices to produce diagnostic images is called a sonographer. The other options listed are roles in radiology, but not specifically for ultrasound imaging.

Question 6

The record produced by an x-ray image of the breast is called a

Accepted Answer

Mammograms are the images produced by the x-ray of the breast. A mammograph or mammography refers to the process of taking the x-ray image, but not the image itself. Mastogram and mastograph are not commonly used terms in medical imaging.

Question 7

Agents such as barium sulfate and iodine, which can be administered orally, rectally, intravenously, or in an artery to enhance the real-time imaging of dynamic processes in blood vessels, or peristalsis in the GI tract are called ________ agents.

Accepted Answer

The answer of Agents such as barium sulfate and iodine,...

Question 8

The abbreviation for the imaging technique which uses strong magnetic fields to produce cross-sectional images is

Accepted Answer

MRI stands for Magnetic Resonance Imaging, which uses strong magnetic fields to produce cross-sectional images. IR stands for Infrared Radiation, CT stands for Computerized Tomography, DR stands for Digital Radiography, and MLO stands for  Mediolateral Oblique, which is a position used in mammography.

Question 9

The transmission of radiographic digital images from one location to another for interpretation by a radiologist is called

Accepted Answer

The transmission of radiographic digital images from one location to another for interpretation by a radiologist is specifically referred to as teleradiology. The other options listed are either unrelated or refer to different aspects of radiology.

Question 10

In the medical term craniocaudal, the root means

Accepted Answer

"Craniocaudal" is an anatomical term that describes a direction from the head (cranial) to the tail (caudal), so the root "caudal" means "tail".

Question 11

Identify the root/combining form and its meaning in the medical term ultrasonography.

Accepted Answer

The root/combining form in ultrasonography is "sono" which means sound.

Question 12

A patient is scheduled for an oblique chest x-ray.This means that the

Accepted Answer

An oblique chest x-ray involves the x-rays traveling at an angle through the chest, which allows for visualization of the lungs from a different perspective. It is different from a standard PA (posterior-anterior) or AP (anterior-posterior) chest x-ray where the x-rays travel from the back or front to the opposite side of the chest.

Question 13

X-rays, like light and radio waves, are a form of ________ radiation.

Accepted Answer

The answer of X-rays, like light and radio waves, are...

Question 14

The term which means a line of central support and comes from the Greek meaning central support is

Accepted Answer

The term that means a line of central support and comes from the Greek meaning central support is axis. The axis is the second cervical vertebra of the spine, which serves as a pivot around which the first cervical vertebra and the skull rotate.

Question 15

The medical specialty that uses imaging techniques to diagnose and treat disease which can be visualized within the human body is ________.

Accepted Answer

The answer of The medical specialty that uses imaging techniques...

Question 16

The vertical plane that divides the body into front and back portions is the ________ plane.

Accepted Answer

The vertical plane that divides the body into front (anterior) and back (posterior) portions is the coronal plane. The other options refer to different planes: sagittal plane divides the body into left and right portions, midsagittal plane is a specific type of sagittal plane that divides the body into equal left and right halves, and transverse plane divides the body into upper and lower portions. "Axial plane" is not a commonly used term in anatomy.

Question 17

PET images can be fused with ________ and ________ images to improve diagnostic accuracy.

Accepted Answer

PET imaging is often used in conjunction with CT or MRI imaging to improve diagnostic accuracy. CT provides anatomical details while PET provides metabolic and functional information. MRI also provides anatomical details and can offer higher resolution than CT, but is less commonly used due to the higher cost and longer acquisition times. SPECT and scintigraphy are both nuclear medicine imaging techniques that use radioactive isotopes, but they are not typically used in conjunction with PET imaging. IR (infrared) imaging is not used in conjunction with PET imaging.

Question 18

In the medical term tomography, the root/combining form means

Accepted Answer

Tomography is a medical imaging technique that uses cross-sectional images to create a three-dimensional representation of an object. The root/combining form "tomo" means "section" or "cut," which refers to the process of creating these cross-sectional images.

Question 19

Which of the following statements regarding radiation doses delivered to a patient during a nuclear medicine procedure is correct?

Accepted Answer

During nuclear medicine procedures, radioactive drugs are administered to patients. These drugs decay and are excreted through urine and stool within a matter of hours or days, and do not cause long-term radiation exposure. The other statements are incorrect: A) The risk of developing cancer from nuclear medicine procedures is low, and potential benefits often outweigh risks. B) Nuclear medicine procedures can be used in patients with liver and kidney disease, and the dose can be adjusted accordingly. C) Side effects are possible, but generally mild and short-lived. E) Depending on the specific procedure, some patients may be advised to limit contact with children for up to 24 hours following the procedure, but not for one month.

Question 20

The most commonly used tracer for the destruction of thyroid tissues is

Accepted Answer

Iodine-131 is the most commonly used tracer for the destruction of thyroid tissues because it emits both beta and gamma radiation, which can penetrate and kill thyroid cells.
