Reasons to Go Beyond 16-slice CT
Greater spatial resolution for
improved differential diagnosis
Improved image quality
without artifacts
Higher temporal resolution
for robust cardiac imaging
Faster volume coverage where
needed, e.g. arterial CTA and PE

� Can Dual-Source MDCT Technology Provide 83 ms Temporal
Resolution for Single Segment Recon.of Coronary CT Angio.?Mannudeep Kalra MD
Compared to single source MDCT (165MS temporal resolution for single segment
reconstruction), the dual source MDCT scanner has better temporal resolution of 83
MS for single segment reconstruction of ECG gated CCTA. Faster, dual source
MDCT can improve image quality of CCTA, evaluate patients with higher heart rate in
shorter time, and avoid artifacts from cardiac motion.

� Design of a 64-Slice Dual-Source CT (DSCT) Scanner
Herbert Bruder PhD
Due to the constant temporal resolution of DSCT, which is below 100 ms for all heart
rates, coronary CTA exams can be performed without beta-blockers. Compared to
single source 64-slice MSCT, the fast volume coverage (increased pitch values),
combined with efficient mA modulation, enables cardiac CT examinations at 30-57%
of the radiation dose.
� Dose Performance of a New 64-Channel DSCT ScannerCynthia McCollough PhD
The use of a cardiac wedge filter, 310 ms pulsing window, HR-dependent pitch, and
3-D adaptive filtering allows DSCT to achieve 85 ms temporal resolution – at
equivalent image noise and with a single-segment reconstruction - using only 30 to
57% of the dose of MDCT (factors of 1.7 to 3.0 reduction in dose).
