Scanning with low kV

Discover the great impact of low kV imaging. The following clinical cases are scanned with low kV and see its power on the reduction of radiation dose or the contrast media administration.

Case 4: CT chest abdomen pelvis angiography

SOMATOM Force

Diagnosis: A re-evaluation CTA using only 20 mL of contrast media confirmed a Stanford B aortic dissection, beginning behind the junction of the left subclavian artery and stretching to just below the diaphragm, with a new partially thrombotic occlusion of the false lumen.

Scan length: 673.6 mmCTDIvol: 2.09 mGy
Rotation time: 0.25 sEff. dose: 2.3 mSv
