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
