Computed tomography (CT) BoardReview - Body CT The Essentials
1. Computed tomography (CT) is at the heart of every modern
radiology department because of its:
1. speed
2. reliability
3. ability to separate overlapping structures: 1, 2, & 3
2. The primary interaction with the anode is excitation
resulting in radia- tion.: Infrared (heat)
3. T/F:
X-rays pass through the patient interacting with tissue by
absorption or scattering, which results in a measured
attenuation of the incident beam.: True
4. Once the data has been acquired, the CT gantry rotation
and the computer renders the raw projection data as an
image set.: Decelerates
5. A sharpening kernel is commonly referred to as a
kernel used to accentuate fine pulmonary or osseous detail,
but simultaneously increases noise.: Bone
6. Numerous formats are available to store images,
including:: a. JPEG
, b. GIF
c. PNG
7. Hodgkin lymphoma accounts for the majority of
lymphomas.: Thymic
8. Carcinoid tumors arising in the thymus tend to be far more
aggressive
than their pulmonary counterparts, primarily as a result of
high rates of local reoccurrence and:: Metastasis
9. Ectopic parathyroid tissue is a cause of anterior
mediastinal mass.: Rare
10. The middle mediastinum is located between the anterior
and posterior compartments and contains the:
1. heart
2. pericardium
3. trachea: 1, 2, & 3
11. are the most common tumors of the peripheral
nerves.: Schwannomas
12. Because many pulmonary structures and abnormal
findings are smaller than mm, imaging of the chest is
preferably performed using high resolution CT (HRCT)
technique.: 3
13. Lung is defined as increased attenuation of the lung
that obscures the underlying architecture.: Consolidation
