PET MYOCARDIAL PERFUSION STUDY AT REST AND DURING PHARMACOLOGICAL STRESS

DATE: 10/5/2005

PROCEDURE:  After IV injection of N-13 ammonia, images of resting myocardial perfusion were acquired on a Siemens/ CTI PET scanner.  Under physician supervision with cardiac monitoring, a pharmacological stress test was performed, and the patient was reinjected with N-13 ammonia for stress imaging.  The rest and stress images were reconstructed into transaxial images with attenuation correction from a pre-injection transmission scan.  Both image sets were re-sliced into short-axis, vertical long-axis, and horizontal long-axis images.

Pharmacologic stress agent and dose:  Dipyridamole [...] mg, Adenosine: [...] mg

REST N-13 Ammonia DOSE: [30] mCi

STRESS N-13 Ammonia DOSE: [30] mCi

SESSION NUMBER:  p00000

COMPARISON: None

CLINICAL HISTORY: The patient is a [...]-year-old [fe]male with a history of [...] who is being evaluated for stress induced ischemia.  

PHARAMACOLOGIC RESPONSE: 

ECG at rest: Normal sinus rhythm.

ECG with stress: No ischemic ST segment changes.

Stress Response:

Heart rate at rest: [...] beats per minute

Heart rate at peak stress: [...] beats per minute

Blood pressure at rest: [...] mmHg

Blood pressure at peak stress: [...] mmHg

Symptoms: Mild shortness of breath, flushing that resolved 1-2 minutes post adenosine infusion.

Aminophylline Required: None

Left ventricular chamber size: Normal

Perfusion Rest: Homogeneous, normal tracer uptake in all regions.

Perfusion Stress: Homogeneous, normal tracer uptake in all regions.

CONCLUSIONS:

1. Normal left ventricular chamber size.

2. Normal myocardial perfusion with no evidence for stress-induced ischemia.

3. The likelihood for hemodynamically significant coronary artery disease is very low.

Thank you for referring this patient to the UCLA Nuclear Medicine Clinic.
