resting imaging

Resting imaging shows the uptake and distribution of the radionuclide imaging agent by the heart while the patient is at rest. It is often used in conjunction with motion imaging. 15 minutes to 30 minutes after intravenous injection of the imaging agent, the patient took 250 ml of milk or yogurt, and the myocardial plane or tomography was performed 1 h to 2 h later. Basic Information Specialist Category: Oncology Inspection Category: Radionuclide Applicable gender: whether men and women apply fasting: fasting Tips: Fasting 3-4h before the test. Normal value The radioactivity does not change much in a certain period of time, so it is allowed to collect radioactive counts that meet the statistical requirements for visualization, so the resulting images are clear and of good quality. Clinical significance Abnormal results: the diagnosis and risk grading of coronary heart disease, to determine the location, extent and extent of ischemic or infarction lesions, can assess the risk of various cardiac events in the future. Auxiliary diagnosis of myocardial disease. Patients with myocardial disease and coronary heart disease who need to be examined can be examined. Precautions Forbidden before examination: fasting 3-4 hours before the test. Requirements for examination: 15 minutes to 30 minutes after intravenous injection of the imaging agent, the patient took 250 ml of milk or yogurt, and the myocardial plane or tomography was performed 1 h to 2 h later. Inspection process Myocardial tomography was performed 60-90 min after intravenous injection of 99mTc-MIBI740MBq. The acquisition matrix was 64×64, the probe was rotated 180°, and 32 original images were acquired. After reconstruction, three cross-sectional images of short axis, horizontal long axis and vertical long axis were obtained. After 48 hours, 0.5 mg of NTG was taken under the tongue 5 minutes before the intravenous injection of radioactive drugs, and the resting state was taken after taking the drug. The instruments used for the 2nd imaging, the dose of the nuclide and the acquisition conditions were the same. Not suitable for the crowd Inappropriate crowd: None. Adverse reactions and risks Nothing.
