Abstract
The aim of this study was to
investigate the variation of the size of
pulmonary vein ostia during cardiac
cycle using ECG-gated multi-detector
row CT (MDCT). Nineteen patients
were included in this study. Transaxial
images at the level of right inferior
pulmonary vein (RIPV) were reconstructed
in increments of 5%. The
ostial diameter of RIPV was measured,
the reconstruction windows showing
maximal and minimal diameters were
selected. The ostial areas of four
pulmonary veins were measured at
axial image sets of two selected
reconstruction windows. The measurement
of RIPV revealed that the
maximal diameter (1.50±0.32 cm) was
generally 35% and the minimal diameter
(1.28±0.28 cm) was usually at
85%. The measurement of ostial areas
showed that the ostia enlarged at the
end of ventricular systole when compared
with those at the end of ventricular
diastole, by the factors of 1.44±
0.55 for the right superior, 1.25±0.23
for the right inferior, 1.45±0.81 for the
left superior, and 1.31±0.26 for the left
inferior pulmonary vein (P<0.05). The
size of the pulmonary vein ostia is
variable during the cardiac cycle and
the measurement of the pulmonary
veins should always be in the same
phase of the cardiac cycle during the
follow-up of patients.
