CAT cardio05

18F-FDG CARDIAC PET-CT

DESCRIPTION: Study of the metabolism of cardiac glucose, as part of myocardial perfusion studies.

ATTENUATION CORRECTION CARDIAC PERFUSION PET-CT

POST-PHARMACOLOGIC-INTERVENTION DIPYRIDAMOLE, DOBUTAMINE)
CARDIAC PERFUSION TOMOSCINTIGRAPHY (SPET) 

DESCRIPTION: Normofunctional study of myocardial perfusion by intravenous administration of a radiotracer marked with technetium or thallium to evaluate the alterations of myocardial perfusion (necrosis, viability, ischemia). A cardiologist performs a cardiac stress test with physical exercise (or pharmacological stimulation). The aim is to increase heart oxygen consumption through the increase of cardiac overload produced by a maximum subjective effort. This test can detect regional reductions in the myocardial flow reserve.

PREPARATION: Three to four-hour fasting is required. In the case of pharmacological stimulation with dipyridamole, it is essential to avoid consumption of xanthines (caffeine, theophylline: coffee, Coca Cola, tea) three days before the procedure. Depending on the drug, the weight of the patient and the criterion of the nuclear doctor, the stress and rest detection sessions can be performed the same day (short protocol) or on different days (long protocol).

INDICATIONS: Diagnosis of coronary artery disease and localization of ischemia. Evaluation of post-revascularization myocardial perfusion (percutaneous transluminal coronary angioplasty-PCTA- or surgery). Evaluation of myocardial viability. Predictive evaluation of ischemic heart disease. Evaluation of the risk of non-cardiac surgery in the patient with ischemic heart disease.

DURATION OF PROCEDURE: 4 hours.

CAT cardio06

REST CARDIAC PERFUSION
TOMOSCINTIGRAPHY (SPET)

DESCRIPTION: Normofunctional study of myocardial perfusion in a baseline situation by means of the intravenous administration of a radiotracer marked with technetium or thallium to evaluate the alterations of myocardial perfusion at rest (extension of necrosis and myocardial viability).

PREPARATION: No previous preparation is required. It may be necessary to administer sublingual nitrates and to monitor blood pressure.

INDICATIONS: Evaluation of the extent of myocardial necrosis. Assessment of myocardial viability.

DURATION OF PROCEDURE: Administration-detection times depend on the radiotracer used (thallium: 3-4 and 24 hours, technetium compounds: 60 minutes).

CAT cardio07

GATED/NON-GATED EQUILIBRIUM ISOTOPE VENTRICULOGRAPHY (STRESS/REST)

POST-PHARMACOLOGIC-INTERVENTION (DOBUTAMINE) EQUILIBRIUM ISOTOPIC VENTRICULOGRAPHY

DESCRIPTION: Evaluation of blood circulation through the heart and assessment of its pumping and contracting function after physical effort. The systolic and diastolic function of both cardiac ventricles is assessed, as well as their overall ejection fraction, the regional left ventricle ejection fraction, and the regional contractility. The procedure also allows for the calculation of ventricular volumes during the effort phase.

PREPARATION: A 4-hour minimum fasting is required.

INDICATIONS: Assessment of left ventricular ejection fraction behavior at rest and the subsequent response to a physical effort, mainly for the diagnosis of coronary artery disease of patients who have suffered a cardiac infarction and for the evolutionary control of patients with aortic insufficiency.

DURATION OF PROCEDURE: 90 minutes.

CAT cardio08

REST EQUILIBRIUM ISOTOPE VENTRICULOGRAPHY

GATED-SPET ISTOTOPE VENTRICULOGRAPHY

DESCRIPTION: Evaluation of blood circulation through the heart and assessment of its pumping and contracting function IN BASELINE SITUATION. The systolic and diastolic function of both cardiac ventricles is assessed, as well as their overall ejection fraction, the regional left ventricle ejection fraction, and the regional contractility. The procedure also allows for the calculation of ventricular volumes.

PREPARATION: No previous preparation is required.

INDICATIONS: Ischemic cardiophaty: Diagnosis: Evaluation of ejection fraction of left ventricle at rest and the existence of alterations of the regional contractility. Acute cardiac infarction: Stratification of patients according to their functional situation after necrosis by means of ejection fraction measurements, being this and VTS the parameters with the highest prognostic value after an infarct; evaluation of regional contractility (areas of hypokinesia, akinesia or dyskinesia, and detection of right ventricle infarction) and study of ventricular remodeling after necrosis. Valvulopathies: evolutionary control of the function and ventricular volumes. Conduction disorders: Evaluation of ventricular function and description of the myocardial contraction sequence: pacemaker situation, pre-excitation syndromes, ventricular tachycardia. Myocardiopathies: Evolution of the function in myocardial pathology of any etiology. Control of myocardial involvement by chemotherapies (adriamycin).

DURATION OF PROCEDURE: 1 hour.
