Clarissa complained of shortness of breath and currently has a pacemaker. A myocardial perfusion imaging, tomographic (SPECT), multiple studies, was done. What is the appropriate CPT code for this procedure? a. 78452
b. 78451
c. 78453
d. 78456

a. 78452

Explanation:

Myocardial perfusion imaging is use to assess myocardial viability or to determine the extent of myocardial ischemia. SPECT systems is widely using now a days as imaging can be done in less than 10 minutes.

The appropriate CPT code for the procedure that Clarissa is undergoing is  78452. 78452 include multiple studies at stress or rest condition by providing injection of radionuclide in  resting phase before taking resting images. This code also determine radioactivity distribution counts arising from certain areas such as anterior wall counts may be reduced.

Hence, the correct option is a. 78452

protocol for imps extraction focusing on membrane protein extraction, solubilisation, and purification.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
