Diagnostic Imaging Exam 2

Front 1

When to order an inspiratory & expiratory film?

Back 1

Foreign body

Front 2

When to order an expiratory film?

Back 2

Small pneumothorax

Front 3

When to order a decubitus film?

Back 3

Pleural Effusions

Front 4

The quality of the film is dependent on which three factors?

Back 4

Inspiration

Penetration

Rotation

Front 5

How to know if the patient had an adequate degree of inspiration?

Back 5

Count 6 ribs on the right anterior hemidiaphragm, 10-11 ribs on the posterior.

The anterior 7th rib should meet at the midclavicular line.

Front 6

If the patient didn't inspire enough, what can the film mimic?

Back 6

CHF, pneumonia

Front 7

Area of increased density in the lung means one of four possibilities:

Back 7

Consolidation

Interstitial

Nodule/Mass

Atelactasis

Front 8

Any pathologic process that fills the alveoli with fluid, pus, blood, cells (including tumor cells) or other substances resulting in lobar, diffuse or multifocal ill-defined opacities. When it reaches a fissure the spread stops there.

Back 8

Consolidation

Front 9

A Pneumothorax is diagnosed using which modality?

Back 9

Lateral decubitus CXR

Patient lies on opposite site of the suspected pneumothorax to accentuate the view.

CT

Front 24

Diagnostic study of choice for a bronchiectasis?

Back 24

HRCT

Front 25

Diagnostic study of choice for COPD?

Back 25

HRCT

Front 26

Most common cause of a benign pulmonary tumor?

Back 26

Granuloma

Front 27

Dilatation of pulmonary vessels proximal to embolism along with collapse of distal vessels, often with a sharp cut off.

Back 27

Westermark sign - Pulmonary embolism

Front 28

Diagnostic study for Pulmonary Embolism?
