[8] Thorax & Chest CT Imaging

Which one of the following is NOT the indication for CT chest/thorax?

• Mediastinal mass

• Pulmonary embolism

• Small cell lung carcinoma

• Retinoblastoma

How the arms positining during the CT chest/thorax?

• Arms by side

• Arms elevated above head

• Arms on the chest

• Arms on the abdomen

One of the post-processing technique in CT chest/thorax is MPR which is creating other planes of images (sagittal & coronal) from the axial. What is MPR stand for?

• Multiplanar reformation

• Maximum intensity projection

• Minimum intensity projection

• Multiplanar redistribution

Why in CT chest/thorax, the shortest scanning time is very important?

• To produce lung window images

• To produce mediastinal window images

• To reduce the motion artifact due to heart & inspiration

• To reduce patient dose

CT of the airway (CT bronchography) is routinely performed during __________

• inspiration

• expiration

The best setting to rule out heart tissue in CT chest/thorax by using _______________ window images.

• mediastinal

• lung

• bone

The best setting to rule out interstitial disease inside the lungs in CT chest/thorax by using _______________ window images.

• mediastinal

• lung

• bone

Hight Resolution Computed Tomography (HRCT) of the lung using _____________
