ARRS: Harmonic Imaging Identifies Hard-To-See Breast Cysts
[04/30/2001; Doctor's Guide]
SEATTLE, WA -- April 30, 2001 -- Breast harmonic imaging, a new
ultrasound technique, can be successfully used to diagnose hard-to-see
A study shows this technique could eliminate the
need for some biopsies. A study of 30 patients with 117 breast
cysts found that harmonic imaging provides higher resolution
and better detail of small cysts or cysts that are deeper in
the breast than conventional ultrasound, says Derek Muradali,
MD, of the University Health Network and Mount Sinai Hospital
in Toronto, Ontario.
The patients in the study underwent a conventional
ultrasound examination and a harmonic imaging examination. Two
radiologists reviewed both sets of images and found-- in 80 percent
of the cases-- that harmonic images were "superior to conventional
ultrasound," says Dr. Muradali. The radiologists did not know
which images were conventional and which were harmonic when they
made their assessment, adds Dr. Muradali.
"Harmonic imaging is now available on some ultrasound machines,
and we just simply flip a switch on the machine to change to
the harmonic image," says Dr. Muradali. Harmonic imaging has
been used in the past, but it is only recently that linear transducers
(the probes) used in breast ultrasound have become available
for use in harmonic imaging, notes Dr. Muradali.
