With the new 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.

Collimation: 2 x 192 x 0.6 mm
Spatial resolution: 0.24 mm
Scan time: 1.44 s
Scan length: 727 mm
Rotation time: 0.25 s
Tube settings: 90 kV, 194 mAs
DLP: 334 mGy cm
CTDIvol: 4.4 mGy
Eff. dose: 5.0 mSv
Contrast media: 40 mL


Thanks to the new Vectron tube, 70 kV imaging is also applicable with the Adaptive 4D Spiral Plus. The combination with the Adaptive Dose Shield allows for the coverage of long ranges at very low doses. In this dialysis patient (dialysis shunt), a high-grade stenosis could be safely identified with only 20 ml of contrast media.

A SOMATOM Force coronary CTA shows the noninvasive diagnosis of a patent stent at 70 kV and 0.24 mm spatial resolution. With the new Cardiac Turbo Flash mode higher intravascular contrast at lower radiation doses are possible. Thus making this mode the first choice for the detection of early signs of coronary heart disease.

Collimation: 2 x 192 x 0.6 mm
Spatial resolution: 0.24 mm
Scan time: 0.18 s
Scan length: 144 mm
Rotation time: 0.25 s

DLP: 31 mGy cm
CTDIvol: 1,77 mGy
Eff. dose: 0.4 mSv
HR independent Temp resolution: 66 ms


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

Collimation: 2 x 192 x 0.6 mm
Spatial resolution: 0.24 mm
Scan time: 0.7 s
Scan length: 294 mm
Rotation time: 0.25 s

CTDIvol: 2.38 mGy
Eff. dose: 1.16 mSv
Contrast media: 30 mL


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 pitchdependent field of view, ranging from 35 to 50 cm, and is suitable for patients up to 220 kg.

Collimation: 2 x 192 x 0.6 mm
Spatial resolution: 0.24 mm
Scan time: 0.2 s
Scan length: 125 mm
Rotation time: 0.25 s
Tube settings: 100 kV, 581 mAs
DLP: 99 mGy cm
CTDIvol: 5,76 mGy
Eff. dose: 1.7 mSv
Contrast media: 40 mL
HR independent Temp resolution: 66 ms


This liver perfusion study, with a liver metastasis, was acquired with the new Stellar Infinity detector and the Adaptive 4D Spiral Plus, in combination with the Adaptive Dose Shield. Prior to targeted therapy, the baseline blood flow quantification was dynamically acquired over a range of 22 cm at very low perfusion dose.

Collimation: 192 x 0.6 mm
Spatial resolution: 0.24 mm
Scan time: 35 s
Scan length: 176 mm
Rotation time: 0.25 s

DLP: 948 mGy cm
CTDIvol: 49,4 mGy
Eff. dose: 14 mSv
Temporal resolution: up to 1.5 s cycle time


The new 90/150 kV Sn mode and a 35 cm field of view allow for obese DE examinations (male, 48 years, 100 kg). The new Selective Photon Shield II increases energy separation by 30%. This combination expands DE information also to challenging patients for more precise tissue and material decomposition.

Collimation: 2 x 192 x 0.6 mm
Spatial resolution: 0.24 mm
Scan time: 3.6 s
Scan length: 309 mm
Rotation time: 0.25 s
Tube settings: 90/150 kV Sn, 104/76 mAs
DLP: 187 mGy cm
CTDIvol: 5.54 mGy
Eff. dose: 2.6 mSv
