Anatomy and Imaging Review

Identify the imaging modality

• x-ray (radiograph)

• Magnetic Resonance (MR)

• Computed Tomography (CT)

• fluoroscopy

Answer explanation

MR uses radio waves and strong magnetic fields. These images have better contrast resolution than CT, highlighting subtle differences in soft tissues.

Identify the imaging modality

• x-ray (radiograph)

• Magnetic Resonance (MR)

• Computed Tomography (CT)

• fluoroscopy

Answer explanation

CT scans have excellent spatial resolution, defining the edges of borders. Notice that soft tissues have a grainy appearance when compared to an MRI scan.

Identify the imaging modality

• x-ray (radiograph)

• Magnetic Resonance (MR)

• Computed Tomography (CT)

• fluoroscopy

Answer explanation

Radiographs are best at imaging bony anatomy.

Identify the imaging modality (set of images)

• x-ray (radiograph)

• Magnetic Resonance (MR)

• Computed Tomography (CT)

• fluoroscopy

Answer explanation

This is called a fluoroscopy swallow test, or a barium swallow.

What anatomical plane is being displayed?

• coronal

• axial

• sagittal

• oblique

What anatomical plane is being displayed?

• coronal

• axial

• sagittal

• oblique

Which image is displayed in the coronal plane?

• 
• 
• 
• 

Identify the imaging modality

• Computed Tomography (CT)

• Magnetic Resonance (MR)

• Positron Emission Tomography (PET)

• fluoroscopy

What substance is usually injected into a patient shortly before a PET scan?

• FDG

• barium

• gadolinium

• air

Answer explanation

FDG is the acronym for fluorodeoxyglucose and is used as a radioactive tracer that is detected by the PET scanner.

Identify the imaging modality

• fluoroscopy

• Computed Tomography (CT)

• ultrasound

• Positron Emission Tomography (PET)

Answer explanation

This is an ultrasound of the brain.
