pharmacologic mycocardial single photon emission computed tomography (SPECT)

Introduction

Also see myocardial perfusion scintigraphy

Indications

• evaluation of myocardial ischemia

Adverse effects

• radiation exposure

Procedure

• computed reconstruction of images obtained from myocardial tissue uptake of Tl-201 or Tc-99
• gating & correction for attenuation with Tc-99
• late perfusion imaging to evaluate myocardial viability with Tl-201

More general terms

• pharmacologic stress testing
• mycocardial single photon emission computed tomography (SPECT)
