Indications:
This is a spiral scanning protocol, using a rotation time
of 0.5 s, ECG gating technique and a dedicated cardiac
filter which can reduce image noise thus provides the
possibility of dose reduction.
Topogram:
AP, 512 mm.
Approximately, from
the carina until the
apex of the heart.
A typical range of
12 cm covering the
entire heart can
be done in 28.7 s.
