What is SPECT? SPECT stands for single photon emission computed tomography. A radioactive tracer like technetium sestamibi is injected into a vein and a nuclear scan using a gamma
Positron Emission Tomography (PET) in Cardiology Positron emission tomography (PET) imaging is useful in assessment of myocardial perfusion and viability, atherosclerotic plaque activity as well as cardiac innervation
Positron emission tomography (PET) is usually taken as the gold standard for assessment of myocardial viability. A mismatch between perfusion and metabolism whereby underperfused region of myocardium is
Balanced myocardial ischaemia If all three major coronary branches have similar degree of stenosis, the radionuclide used for perfusion study will have equal uptake in all regions of
Single photon emission computed tomography (SPECT) - pros and cons: Important advantages of SPECT are that it has been extensively validated and has a good sensitivity, compared to
Thallium 201 single photon emission computed tomography (SPECT) Thallium 201 SPECT imaging is one of the oldest methods of assessing myocardial viability, though of late it is seldom
Reversed mismatch on PET (Positron Emission Tomography) scan is seen in: Left bundle branch block Right ventricular pacing Non ischemic cardiomyopathy All of the above Correct answer: 4)
Tracer used to assess cardiac sympathetic denervation: a) 11C-meta-hydroxyephedrine b) Technetium (99mTc) sestamibi c) Fludeoxyglucose (18F) d) None of the above Correct answer: a) 11C-meta-hydroxyephedrine Myocardial sympathetic denervation assessed by 11C-meta-hydroxyephedrine has been shown
FDG-PET CT in prosthetic valve and device related endocarditis FDG-PET CT in prosthetic valve and device related endocarditis: Prosthetic valve endocarditis and intracardiac device related endocarditis are difficult
PET CT in aortic disease Positron emission tomography using fluorodeoxyglucose is useful in detecting areas of high metabolic activity as in case of inflammatory cells and malignant cells.
