100
This term describes a curvature of the spine that is convex (curves outward posteriorly), commonly found in the thoracic and sacral regions
What is kyphosis?
100
In this standard chest film view, x-ray beams pass from the back of the patient to the front while they are standing upright
What is a PA (Posterior-Anterior) view?
100
On a standard radiograph, this substance represents the least dense material and appears completely black
What is air?
100
On an oblique radiograph of the spine, this anatomical part of the vertebra forms the "neck" of the "Scottie Dog" and is the site of spondylolysis
What is the pars interarticularis?
100
This imaging modality is non-ionizing and utilizes sound waves and the varying densities of soft tissues to generate images
What is ultrasound?
Bonus Points: Other than OB's, who is this imaging modality the best for?
200
This term refers to a structure that appears bright or white on a Computed Tomography (CT) scan
What is hyperdense (or hyperattenuated)?
200
This imaging plane, also called the transverse plane, captures the patient as if they are being viewed from their feet while lying supine
What is an axial view?
200
Cerebrospinal fluid (CSF) will appear bright or white on this specific type of MRI pulse sequence
What is a T2-weighted image?
200
A lateral view radiograph of the skull showing the "Turkish Saddle" depression in the sphenoid bone
What is the sella turcica?
200
Because it uses powerful magnets, this imaging modality is generally contraindicated for patients with cardiac pacemakers
What is MRI?
300
his clinical term describes the premature fusion of cranial sutures, which can lead to abnormal head shapes like scaphocephaly
What is craniosynostosis?
300
To determine if a chest x-ray was taken at full inspiration, a radiologist should be able to count this many posterior ribs above the diaphragm
What is ten?
300
These are the four basic densities recognizable on a standard radiograph?
(dont overthink it!)
What are air, fat, water (soft tissue), and metal (or calcium/bone)?
300
300
Both conventional radiography and Computed Tomography (CT) utilize this form of energy, which carries a risk of tissue energy deposition
What is ionizing radiation?
Bonus Points: Which has more radiation exposure?
400
This ultrasound term describes a fluid-filled structure that does not produce echoes and appears completely black
What is anechoic?
400
In this imaging modality, unlike all other kinds, lateral views can be obtained.
Xray
400
On a T1-weighted MRI, fat typically appears bright, while this fluid between the pia adn arachnoid mater appears dark
What is CSF (or water)?
400
What vertebrae is shown in the following image?
T12
400
This branch of radiology is unique because it focuses primarily on body function and physiology rather than just static anatomy
What is nuclear medicine?
500
In nuclear medicine, a region of increased metabolic activity is described by this "temperature" related term
What is hot?
500
This specific skull view is used to visualize the maxillary sinuses clearly by minimizing overlapping bone from the rest of the skull
What is the Waters view?
500
Unlike on a CT scan where it appears bright white, pure cortical bone will always appear dark or black on this imaging modality
What is MRI?
500
What strucutre is this? (Side Matters)
L pedicle of the L3
500
MRI images are generated based on the interaction between magnetic fields, radiofrequencies, and these specific molecules in the body
What are hydrogen protons (or molecules)?
