HEART

 

heart (normal #1)

Clinical indications: patient w/ metastatic breast cancer who is a candidate for bone marrow transplant - evaluating cardiac status.

Dose: 30mCi Tc-99m-RBC given i.v.

Results: normal size ventricular chambers; w/ exercise there was improvement in wall motion w/ increase in the ejection fraction to 72% in the first exercise stage which remained essentially stable in the second and third exercise stages.

 


heart (normal #2)

Clinical Indication: 55 year white female w/ leukemia - rest and stress NEF.

Dose: 30 mCi Tc-99m labled RBC given i.v.

Results: normal ejection fraction; no evidence of wall motion abnormality.

 


heart (normal#3)

Clinical Indications: 53 year white female w/ chest pain - treadmill thallium scintigraphy.

Dose: 4 mCi TI-201 given i.v.

Results: normal distribution of thallium in myocardium.

 


heart (normal #4)

Clinical Indication: 36 year old white female w/ non-Hodgkins lyphoma - resting NEF.

Dose: 25 mCi Tc-99m RBC given i.v.

Results: heart at upper limits of normal size.

 


heart (normal #5)

Clinical Indication: 66 year old w/ history of breast carcinoma - resting NEF.

Dose: 25 mCi Tc-99m RBC given i.v.

Results: normal

 


heart (normal #6)

Clinical Indication: 42 year old white female w/ breast cancer - NEF, radionuclide ventriculogram.

Dose: 25mCi Tc-99m RBC given i.v.

Results: normal.

 


heart (abnormal #1)

Clinical Indication: 53 year old white female with chest pain and non-diagnostic thallium treadmill test while on beta blockers.

Dose: 56mg/kg dipyridamole thallium.

Results: hypoperfusion of proximal interventricular septum; thallium images show finding consistent w/ impaired coronary flow reserve of the proximal septum.

 


heart (abnormal #2)

Clinical Indication: 52 year old male w/ multiple myeloma - ventilation/perfusion scan.

Dose: 35mCi Tc-99m-RBC given i.v.

Results: no ECG changes to suggest myocardial ischemia; normal ventricular contractions w/ normal left ventricular ejection fraction; normal cardiac reserve capacity.

 


heart (abnormal #3)

Clinical Indication: 55 year old female - resting radionuclide ventriculogram.

Dose: 25 mCi Tc-99m RBC given i.v.

Results: hypercontractile left ventricle with LVEF of 83%; consider high-output state as cause of high ejection fraction.

 


heart (abnormal #4)

Clinical Indication: male with chronic heart failure - nuclear ejection fraction.

Dose: 25mCi Tc-99m RBC given i.v.

Results: left and right ventricular enlargement; hypokinesis of left ventricle.

 


heart (abnormal #5)

Clinical Indication: 67 year old white female w/ history of diabetes mellitus, high blood pressure, coronary artery disease, and CHF now with large cell lyphoma.

Dose: 25 mCi Tc-99m RBC given i.v.

Results: left ventricular enlargement and hypokinesis; halo effect may be consistent with left ventricle hypertrophy, percardial fat, or percardial effusion.
