blood pool imaging

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. Using a gamma camera to align the observed organs for continuous photography, it can be seen that the radioactivity is first perfused with the blood flow and flows through the organ, which can be used to diagnose ischemic brain lesions, unilateral renal artery stenosis, and distinguish benign and malignant lesions. Monitor the vascular anastomosis of the transplanted kidney and so on. Basic Information Specialist Category: Cardiovascular Examination Category: Radionuclide Applicable gender: whether men and women apply fasting: fasting Tips: Iodine allergy or serious condition can not accept X-ray angiography is not suitable for this examination. Do not eat, do not drink sugary drinks and carry out glucose rehydration, keep quiet. Keep quiet during the inspection process, avoid exercise, talk, and chew. Normal value True ventricular aneurysms and aneurysms present local elevation images of wide basement, and pseudoaneurysms and ventricular aneurysms are mostly localized images with thin necks. Clinical significance Abnormal results: The blood pool image is significantly smaller than the X-ray heart shadow, which 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. The people who need to be examined are generally those who have diseases and symptoms in the heart and those who have pathology in the organs need to be examined. Precautions 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 A radioactive imaging agent (such as 99mTc-red blood cells) that does not escape the bleeding bed within a few hours is injected into the vein until it is mixed (ie, equilibrated) in the systemic blood bed. Because of the large amount of blood in the heart chamber and large blood vessels (called the blood pool), there is more radioactivity. The image of the heart chamber and the large blood vessels can be taken with a gamma camera. This method can be used to observe the shape and size of each heart chamber and large blood vessels. Not suitable for the crowd Inappropriate people: Iodine allergies or serious illness can not accept X-ray angiography. Adverse reactions and risks Nothing.
