Equilibrium radionuclide angiography (ERNA)

Balanced radionuclide angiography (ERNA) includes the following 1 blood pool imaging. The blood pool image of the lesions in the liver and spleen is thicker than normal tissue and is a feature of cavernous hemangioma. The 2 wall motion movie showed that the ventricular aneurysm was characterized by no movement of the local wall at rest or abnormal pulsation, and abnormal pulsation after exercise or more obvious. This method is convenient for observing changes before and after treatment to judge the effect. 3 Heart function measurement, the sensitivity to myocardial ischemia is about 85%, higher than the exercise electrocardiogram (sensitivity is about 65%). Because the exercise electrocardiogram is simple, it is still the preferred method for diagnosing myocardial ischemia, but when the results are inconsistent with the clinical situation and the diagnosis, or factors that affect the ECG analysis (such as bundle branch block), you can use this law. This method is also commonly used to observe the efficacy of drugs and surgery. Basic Information Specialist Category: Cardiovascular Examination Category: Radionuclide Applicable gender: whether men and women apply fasting: fasting Tips: Do not eat before the test, can not drink sugary drinks and glucose rehydration, to keep quiet. Normal value Blood pool imaging of true ventricular aneurysms and aneurysms presents a local elevation image of a wide basement. Pseudoaneurysms and ventricular aneurysms are mostly localized images with thin necks. The wall motion movie showed normal motion of the wall and no specificity. Cardiac function determination The normal left ventricular EF was greater than 0.50 and the right ventricular EF was greater than 0.40. After the second extreme exercise, both increased by 0.05 or more. Clinical significance Abnormal results: 1, the blood pool image is significantly smaller than the X-ray heart shadow, is a clear evidence of pericardial effusion. The distance between the left and right ventricle blood pools is significantly widened, which supports the diagnosis of hypertrophic cardiomyopathy. The blood pool image of the lesions in the liver and spleen and other organs is concentrated in normal tissues and is a feature of cavernous hemangioma. 2, the ventricular aneurysm is characterized by no movement or partial abnormal pulsation of the local wall at rest, abnormal pulsation after exercise or more obvious. This method is convenient for observing changes before and after treatment to judge the effect. 3, for early diagnosis of pulmonary hypertension and pulmonary heart disease, myocardial ischemia. Left ventricular myocardial infarction and ventricular aneurysm appear in the shallow zone at rest. The right ventricular wall is very thin and often poorly developed at rest. People who need to be examined: Patients with cardiovascular disease or patients with related diseases can be examined. Positive results may be diseases: heart disease during pregnancy, mitral regurgitation, occult coronary atherosclerotic heart disease, chronic heart failure, painless myocardial infarction, mesenteric aneurysm, dilated cardiomyopathy in children, heart rhythm in children Abnormal right ventricular cardiomyopathy, drug-induced cardiomyopathy considerations Taboo before the test: can not eat, can not drink sugary drinks and glucose rehydration, to keep quiet. Requirements for inspection: Keep quiet during the inspection, avoid exercise, talk, chew. Inspection process It can be used for the diagnosis of congenital heart disease, the diagnosis of large vessel malformation, etc. This method has complementary effects and mutual verification with ultrasound and cardiac catheterization. The method has the advantages of non-invasive, repeatable, quantitative analysis, and dynamic observation. Not suitable for the crowd Inappropriate people: Iodine allergies or serious illness can not accept X-ray angiography. Adverse reactions and risks Nothing.
