Dearborn County Hospital is
Greater Cincinnati’s First and Only Hospital to Offer the PET/CT
Cardiac Stress Test
DCH is the first and only
hospital in the Greater Cincinnati area to offer Positron Emission
Tomography/Computerized Axial Tomography (PET/CT) Myocardial
Perfusion Imaging with rubidium, a new, advanced form of cardiac
stress test. Only hospitals with a PET scanner are capable of
performing this type of cardiac examination.
“Cardiac stress tests that utilize PET/CT provide physicians with
highly sensitive images that are far superior to those commonly
available through the use of traditional nuclear medicine (SPECT)
modalities. PET/CT is currently the most advanced cardiac imaging
technique for heart muscle,” explained Roger Howard, DCH Director of
Clinical Services and Facilities.
A PET/CT cardiac stress test does not require walking on a treadmill
and can be performed in one visit of approximately 45 minutes.
Patients no longer need to come for testing on two consecutive days
or wait for hours between scans. PET/CT cardiac uses a rubidium
isotope as its tracing agent. Because rubidium has a very short
half-life of 75 seconds, examinations of the heart at rest and those
while the heart is being exerted can be performed back to back.
Also, the much shorter half-life of rubidium compared to traditional
tracing agents means the patient is exposed to less radiation.
“While PET/CT cardiac provides an overall superior examination, it
is extremely valuable for obese individuals and female patients with
large breasts,” elaborated Mr. Howard. “Rubidium is more easily
detected through abundant body mass than traditional tracing agents,
providing a more accurate, distortion free image. In addition, the
CT portion of PET/CT also helps the image compensate for differences
in body mass among patients.”
PET/CT cardiac is also
extremely valuable in diagnosing balanced three vessel disease where
three of the four arteries of the heart each have a significant
blockage of approximately the same amount. Using a traditional
cardiac nuclear medicine scan, these arteries may appear as normal
even though three have significant blockages.
The procedure also provides superior images in patients with
diabetes. Persons with diabetes are more prone to have numerous,
small auxiliary vessels compensating for and/or circumventing
larger, partially obstructed arteries.
“Because of the accuracy and abundance of information derived from
the PET/CT cardiac stress test, we anticipate having patients
referred from throughout the Tri-State area. In fact, PET/CT cardiac
is so good, in some cases it may rule out the need for a follow-up
cardiac catheterization. Also, because the trace element, rubidium,
is generated on site, it is possible to schedule and perform an exam
on the same day. This is especially important for patients seeking
cardiac clearance for an unexpected surgery or procedure,” Mr.
Howard stated. “It’s also important to note that while a physician’s
order is required for this test, the ordering physician does not
need to be a member of the DCH Medical Staff.”
