What is the scanning of a cuddle?
Heart PET scan uses Po positron emission tomography (PET) to explore the blood flow and heart function and diagnostics of related disorders. Doctors can also use this non -invasive medical imaging facility for diagnosing other health conditions, including brain and cancer disorders. While scanning magnetic resonance imaging (MRI) and computer tomography (CT) also provide images of anatomical structures, PET scanning shows physiological functional processes.
Doctors believe that PET scan provides more accurate information than conventional electrocardiograms and stress tests in attempting to diagnose heart disease. Doctors may require scanning of heart PET if it suspects that heart disease in patients who show no visible symptoms of vascular flow deficiency. PET scan also provides diagnostic information when doctors suspect heart or vascular problems based on symptoms that occur during physicalexertion or at rest.
The patient of the heart of a cuddle usually receives intravenous (IV) injection of chemicals of radionucleotide combined with glucose. Fluorodeoxyglucose, commonly referred to as FDG, is the most commonly used radioactive tracking material. FDG releases gamma rays that detect the PET scanner when it revolves around the machine. The scanner transmits signals to a computer console that displays signals as an image.
doctors evaluate the path of blood flow to the heart by observing images created by scanning a heart animal. Upon receiving the circulation images, when the patient is calm and relaxed, doctors may require other images after physical exercise or simulated exertion induced drugs such as dipyridamol. Hospital Vasculature shows signs of reduced blood flow during physical activity due to stenosis.
In addition to monitoring the blood flow patterns, the pictures of the petal petThey also illuminate the areas of heart and vasculature that do not absorb the chemicals of glucose loaded IV. These places are areas in which tissue is damaged. Scanning usually provides doctors with the information necessary to decide on a specific treatment plan. Doctors may observe the efficacy of lipid reducing agents or determine whether patients require surgical intervention, including bypass or transplantation procedures.
Since the radiation is involved in the procedure, scanning of heart animals is generally not recommended for pregnant or nursing patients, and diabetic patients may receive special instructions on glucose used in injection. Before the procedure, the period of abstinence from food and drink is required. However, unless the instruction is otherwise, the water is usually allowed before scanning.
