According to a research made by the American Heart Association, more than 80 million suffer from heart diseases. The high number of deaths due to heart disorders has led to the invention of new machines to enhance treatment. The molecular imaging device is the latest technology being used to diagnose cardiovascular diseases. This is why molecular imaging helping with cardiovascular diagnosis is such a good idea.
More information on heart disorders can be detected by using the machine. It assists physicians discover molecular and cellular level changes in the body. Unlike other imaging machines, it detects heart diseases during their early stages.
The extent and severity of the disease can be determined by using this method. With the information it provides, patients and doctors are able to decide on the form of therapy to be used. The effects of the medicine given to the patient can be determined. The main benefit of using the molecular image is the accuracy it has. It accesses the cell and body changes that take place during treatment.
Any recurrence of the disorder can be identified and precautions taken. Progression of the disease and the effects of the medicine can be accessed. Response of the patient to treatment can be evaluated using the new technology. These features make it the best option to use with patients. They are noninvasive, safe, and painless. They are comfortable for both the patient and physician.
Cell changes can be detected early enough, even before the structural changes begin to occur. It works in a bit different way compared to CT, MRI scans and X-rays. The process involves an visualization device and agent. The main role of this agent is to visualize on the cells activities.
Nuclear medicine is a branch of molecular visualization technology. There are also different types of equipments used in diagnosing heart disorders. Myocardial perfusion visualization is one of them, and is used in cardiovascular diagnosis. The blood flow of the patient is evaluated in two phases. It has similar functions, like any other molecular imaging.
Before a doctor decides on the treatment to administer, some procedures will be taken. A stress test is usually the first step. In case a patient is not able to do the exercise, a drug is given. This helps the doctor evaluate the blood pressure of the patient as well as the heart rate. After the stress test, a patient is ready to take the picturing procedure. Radio-tracer, as an agent, is injected to the patient, and it accumulates in the heart muscle.
Once the radio tracer is in, cameras and scanning machines will be used to produce images. SPECT cameras and PET scanners are used to produce three dimensional images. The images clearly show the blood flow as it goes through the arteries to the heart. This is done when the patient has performed a physical test and also when resting. This enables the doctor notice the changes on the flow of blood during the different stages. The scans produced are accurate and clear for the doctor to interpret to the patient. The information gathered by this model of the molecular imaging guides the doctor in giving the best treatment on cardiovascular disorders. It is easy to see how molecular imaging helping with cardiovascular diagnosis.
One of the top digital imaging companies providing modalities specifically designed for preclinical research such as In vivo imaging, in vivo testing micro imaging, high-resolution imaging, scientific Molecular Imaging, digital imaging system.
