Diagnostic value of magnetic resonance imaging in thoracic outlet syndrome.
[thoracic outlet syndrome]
PURPOSE
.
To
evaluate
the
diagnostic
value
of
magnetic
resonance
imaging
(
MRI
)
in
thoracic
outlet
syndrome
(
TOS
)
.
METHODS
.
Medical
records
of
30
women
and
10
men
aged
18
to
68
(
mean
,
38
)
years
who
presented
with
unilateral
(
n
=
35
)
and
bilateral
(
n
=
5
)
TOS
and
underwent
42
surgical
decompressions
of
the
right
(
n
=
23
)
and
left
(
n
=
19
)
sides
were
reviewed
.
MRI
findings
were
compared
with
intra-operative
findings
to
evaluate
the
diagnostic
value
of
MRI
.
RESULTS
.
MRI
findings
correlated
poorly
with
intra-operative
findings
.
Of
the
42
cases
,
MRI
and
intra-operative
findings
were
matched
in
17
and
not
matched
in
25
.
MRI
appeared
normal
but
intra-operative
findings
were
in
fact
positive
for
TOS
in
23
of
24
cases
.
The
sensitivity
and
specificity
of
MRI
in
diagnosing
TOS
were
41
%
and
33
%
,
respectively
,
whereas
its
positive
and
negative
predictive
values
were
89
%
and
4
%
,
respectively
.
CONCLUSION
.
Sensitivity
and
specificity
of
MRI
in
diagnosing
TOS
are
low
.
Diagnosis
should
be
based
on
a
holistic
approach
including
history
,
clinical
examination
,
and
radiological
findings
.
