Cardiac study with and without Hawkeye Cardiac Attenuation

Cardiac study with and without Hawkeye Cardiac Attenuation
Summary:
Patient presents with chest pain. A resting Tc99m perfusion scan is scheduled to evaluate for myocardial infarction. Following standard myocardial perfusion imaging, in the inferior wall, there is a mild severity defect. Left Ventricular systolic function at rest, post stress, is borderline normal; Ejection Fraction equaled 47%. Following Hawkeye CT based attenuation correction, Myocardial Perfusion is normal. Neither transient LV dilatation or increased lung uptake are observed. The Myocardial Perfusion scan is normal, Myocardial Infarction ruled out.

Clinical Information and Procedure:
Patient presents with chest pain. A resting Tc99m perfusion scan is scheduled to evaluate for myocardial infarction.

Findings:
In the inferior wall, there is a mild severity defect. LV systolic function at rest, post stress, is borderline normal; EF equaled 47%.

With Attenuation Correction:
Myocardial perfusion is normal on AC images. Neither transient LV dilatation or increased lung uptake are observed

Impression:
Normal Myocardial perfusion study.
 
Quality Control Display:
Standard quality control display allows for the assessment of Emission to Transmission registration. Three plane visual display provides qualitative sagittal, coronal and transaxial alignment assurance.

Findings:
Exact registration of Emission and Transmission datasets.
