Q

What is standard for diagnosing pulmonary emboli?

A

Pulmonary CTA

17
Q

Coronary CTA

A
  • Contrasted Computed Tomography of the heart
  • Gated
  • Great spatial resolution for non-invasive evaluation of the coronary arteries
  • Can get functional data
18
Q

Echocardiography, describe it

A
  • Ultrasound- Transthoracic or Transesophageal
  • Real-time imaging
  • Functional and Flow data- Can be done with stress
  • Good resolution within the chambers
  • Contrast can identify shunts
19
Q

Describe nuclear imaging…

How is it done?

What kind of camera?

When is it performed?

Gated?

What data does it provide?

What is the spatial resolution like?

A
  • Injection of a radiopharmaceutical
  • Gamma camera
  • Performed at baseline and with stress
  • Gated
  • Provided perfusion and functional data
  • Low spatial resolution
20
Q

Describe cardiac MR

What kind of imaging?

Gated? Contrast?

Describe the spatial and contrast resolution

What data does it provide?

How’s the evaluation of surrounding structures

Unique additional functions?

A
  • Magnetic Resonance Imaging
  • Gated and with IV contrast
  • Great spatial and contrast resolution
  • Functional and flow data
  • Great evaluation of the surrounding structures
  • Unique additional functions - yup
