RADIOLOGY REPORT:
PERSANTINE SESTAMIBI STRESS TEST
CLINICAL INDICATION: Paroxysmal nocturnal dyspnea, pericardial
effusion, diabetes, hypertension, hypercholesterolemia.
PROCEDURE: After obtaining informed consent, patient was infused
intravenously with 58-mg of Persantine over 4-minutes. Stress dose
of the radiotracer was injected intravenously at 7-minutes into the
infusion and the Persantine was reversed at 8 1/2-minutes with
100-mg of Aminophylline.
FINDINGS: The heart rate rose from 68 to the 97 beats per minute.
Blood pressure rose from 146/90 to 153/91 millimeters of mercury.
She had mild chest tightness but no changes from baseline EKG.
IMPRESSION:
1. ADEQUATE RESPONSE TO PERSANTINE.
MYOCARDIAL PERFUSION IMAGING: Rest and gated stress Persantine
Sestamibi stress testing is performed per protocol using 11.3-mCi of
technetium 99m sestamibi at rest and 34.3-mCi at stress.

| Note the absence of any
background activity around the heart. This is due to
the pericardial effusion surrounding the heart. |

FINDINGS: Rest and stress tomographic imaging show homogeneous
distribution of the radiotracer throughout a normal sized left
ventricle. There is a dark halo extending around nearly the entire
heart. This is seen on the raw data, slices, and on the gated
slices.
IMPRESSION:
1. NO PERFUSION DEFECTS NOTED TO INDICATE ISCHEMIA OR SCARRING.
PHOTOPENIC HALO AROUND THE LEFT VENTRICLE CONSISTENT WITH A
PERICARDIAL EFFUSION.
QUANTITATIVE FUNCTIONAL IMAGING: The stress tomographic images were
acquired by the gated technique.
FINDINGS: The ejection fraction is greater than 65%. End diastolic
volume is 97-ml. CINE of the slices shows normal wall motion and
thickening throughout.
IMPRESSION:
1. NORMAL PUMP FUNCTION.
