Two steps ahead


Body


Thoraco-Abdominal Imaging

With the Vectron™ tube, TAVI planning in a heavy patient with chronic kidney disease (shrunken kidney) can be performed at only 90 kV. The increased contrast-to-noise ratio allows the reduction of contrast media down to 40 mL. Due to the minimal renal strain, the patient can soon undergo his subsequent minimal invasive procedure.

In this obese patient, suffering from dyspnea (shortness of breath), Turbo Flash scanning allowed to perform the examination without breath-hold. Maximizing the contrast-to-noise ratio at 70 kV shows great vessel contrast while preserving softtissue contrast – with a contrast media dose of only 30 mL.

Thoracic Imaging

A 140 kg patient was scanned with Cardiac Turbo Flash mode at only 100 kV and 40 mL contrast media. The left main and the left anterior descending artery are shown without artifacts from motion or photon starvation. The new mode allows a pitch-dependent field of view, ranging from 35 to 50 cm, and is suitable for patients up to 220 kg.

Peripheral Imaging

A non-dynamic runoff study of this patient suggests an occlusion of tibialis anterior. However, a 70 kV dynamic 4D angiography scan with only 30 mL of contrast media (400mgl/mL) shows the vessel to be patent, thus sparing the patient a complicated bypass procedure.
