Aim of the prospective single-center study was to investigate the effect of a device-assisted suction against resistance Mueller maneuver on transient interruption of contrast (TIC) in the aorta and pulmonary trunk on computed tomography pulmonary angiogram (CTPA).

The results of the study and a summary can be downloaded via the tile below. 

The results show, that performing the Mueller maneuver with the prototype of the Contrast Booster from ulrich medical can increase contrast attenuation in CTPA and effectively prevent the TIC phenomenon, [...]. Moreover, implementation of a such device in pulmonary embolism (PE) diagnostics with CTPA may enhance diagnostic accuracy and lower the risk of missed PE.
