Acquisitions of 360-degrees are usually performed for bone single phot
on emission computed tomography (SPECT). However, the spine is a perip
heral and median structure; it therefore seemed interesting to compare
the 360-degrees and the posterior 180-degrees SPECT images. In a phan
tom study and in 25 adult patients, the 360-degrees SPECT images were
compared with the posterior 180-degrees images obtained during the sam
e acquisition: the posterior 180-degrees images are at least equivalen
t to the 360-degrees images. With a reduction in the examination time,
SPECT could become easier to perform, especially in patients sufferin
g from back pain.
