Contrast medium protocols in routine chest CT: a survey study.

Acta radiologica (Stockholm, Sweden : 1987)

Henning MK, Aaløkken TM, Johansen S.
PMID: 33648351
Acta Radiol. 2021 Mar 01;284185121997111. doi: 10.1177/0284185121997111. Epub 2021 Mar 01.

BACKGROUND: Administration of contrast medium (CM) is an important image quality factor in computed tomography (CT) of the chest. There is no clear evidence or guidelines on CM strategies for chest CT, thus a consensus approach is needed.PURPOSE: To...

[Stress echocardiography: it is all in the contrast!].

Revue medicale suisse

Ciaroni S.
PMID: 19374047
