The Advantages And Disadvantages Of Imaging Modalities Used In Bioconjugation Systems

The MRI machine and the time it takes perform a scan is the bottleneck of the process. Each scan can have different times associated with it depending on the type of scan that will be performed. This will limit the capacity of the overall process. For example, a scan without contrast will usually take 30 minutes. A scan that requires contrast will double that time to 60 minutes.

The Diagnostic Sonography more commonly known as Ultrasound is a medical procedure in which you use high frequency sound waves to produce visual images of organs tissues or blood flow inside the body. Ultrasound is regularly known as the procedure used to examine women who are expecting. Although, Sonography is used in many different ways other than for expectant mothers. Sonography is also used to detect such things as heart disease, heart attacks, and vascular disease that can lead to stroke. (SDMS, 2010) Moreover, Sonography is also used to examine breasts, abdomens, female reproductive systems,

Purchasing new MRI scanners would be a good investment for the hospital. If one takes into consideration, operating costs along with repairing and purchase of the product alone. Many hospitals may consider wanting to purchase refurbished items but that would not be a good idea considering the costs to maintain and longevity of the product itself. Purchasing a brand new MRI scanner is just like the purchase of a brand new, high end car. Although it may be very expensive to purchase, there will not be so much high maintenance done in the beginning. Once the product gets very old within about ten years, then the high maintenance repairs will need to be done. All equipment

Being able to identify lumps, swelling, tissue damage, cysts, and the overwhelming news of the sex of a baby all have something in common, an ultrasound. Swelling of the spleen, kidney stones, blood clots, aneurysms, cancer and so much more can be identified through the works of an ultrasound’s imaging technique. Ultrasound involves many concepts, procedures, and careers. The amount of medical possibilities involved with ultrasounds is useful in major medical diagnostics. The field of ultrasounds and career opportunities are widely growing. As medical careers flourish, needs for technicians in many fields of medicine are increasing. Instead of a doctor choosing complex and risky surgery to find out problems within the body, they can now

Ultrasound imaging has many uses in medicine, from confirming and dating a pregnancy to diagnosing certain conditions and guiding doctors through precise medical procedures

Another form of imaging is ultrasound. Ultrasound, which uses very high frequency sound, is directed into the body. And because the tissue interference's reflect sound, doctors are able to produce, by use of a computer, a photograph or moving image on a television. Ultrasound has many application uses on the body, but is more commonly used in examinations of the fetus during pregnancy, because use of radiation may affect the outcome of the baby. Some other practices for ultrasound include examination of the arteries, heart, pancreas, urinary system, ovaries, brain, and spinal cord. And because sound travels well through fluids it is a very useful technique for diagnosing cysts( which are filled with fluid), and fluid filled structures such as the bladder. And since sound is absorbed by air and bone it is impossible to use a ultrasound on bones or lungs.

Diagnostic medical sonography is a profession where sonographers direct high-frequency sound waves into a patient’s body through the use of specific equipment to diagnose or monitor a patient’s medical condition. As described by the Bureau of Labor Statistics, this examination is referred to as an ultrasound, sonogram, or echocardiogram. The high-frequency sound waves emitted from the handheld device, called a transducer, bounce back creating an echo and therefore produce an image that can be viewed on the sonographers computer screen. This image provides the sonographer and physician with an internal image of the patient’s body that will be used in the diagnosis. The most familiar use of ultrasound is used in monitoring pregnancies

As my sweaty hands lay on top of my stomach, I glanced at what seemed to be the end of the machine. The only section that was lit and in my mind, the only part of me that was safe. I had gone through this twice already, but I hadn’t made it inside the MRI machine and never thought I would.

Sonography utilizes sound waves to generate an image that can be analyzed to determine or rule out a diagnosis. Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. A diagnostic medical sonographer works directly with patients in a dimly lit room with imaging machines. The sonographer gets the medical history of the patient and prepares the patient for an ultrasound examination. The sonographer explains the noninvasive procedure and answers any question the patient might have. The sonographer positions the patient and covers the patient only exposing the area needed for the procedure. The sonographer

Diagnostic medical sonographers play a key role in the health care team and often work alongside doctors, nurses, and other technologists. They prepare patients by explaining the procedure and collect necessary patient history information prior to examination. An ultrasound is then performed, which is a non-invasive process that enables sonographers to send high-frequency sound waves into the body. The return signals are then analyzed to help visualize internal organs in 2D, 3D or 4D. These images help physicians with medical diagnoses and are also used for monitoring pregnancy. An ultrasound is often executed on many different areas of the body including the abdomen, pelvis, tissues, and vascular and cardiac systems. A DMS may also be required

One of the authors patients of that very day was order a multitude of tests, when, one test being the ultrasound, held a better stand in imaging or screening over the others but she was asked to do all the test. An additional test, that was not necessary, added to the cost of health care for that patient. The article mentions over testing and over treatment in one way or another, cost thousands of dollars that come out of paychecks from every household each year. The excesses use of these tests and accruing cost has been looked at as financial and physically toxic in the name of health care. As a patient inquiring which test would best help bring about a conclusion to a symptom, could exclude the extra test altogether, unless the other test is acquired after all possible conclusions have been

"The new improvements are designed to address those issues. Try to alleviate some of the fears, try to make them feel more comfortable, more in control of their environment while they're getting an MRI. They can choose their lighting, their sound, the video they watch. They can also play DVDS if we have one that they like," says MRI Team Leader Shelia Turner.

Medical ultrasound (also known as diagnostic sonography or ultrasonography) is an diagnostic imaging technique based on the application of ultrasound. It is used to see internal body structures such as tendons, muscles, joints, vessels and internal organs. The aim of often to find a source of a disease or to exclude any pathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound, and is widely used.

There are always going to be advantages and disadvantages in anything that is developed in the area of technology. MRI is no different.

The patients who filled out a questionnaire one week prior to the MRI scan answered questions concerning the characteristics of depression, anxiety, stress, confinement and suffocation. The patients who filled out a questionnaire immediately after the MRI scan answered questions concerning their experience, did they complete or not complete the MRI scan, their willingness to undergo a further scan, and the history of previous MRI scans. Claustrophobia 3 The patients who filled out a questionnaire one month after the MRI scan filled out the same questionnaire as the one prior to the MRI scan. The results of this MRI scan study proved that patients who had failed to complete their MRI scan experienced an increase in the claustrophobic fear since they left during the MRI scan while their fears were high, which reinforced these patients from escaping from a similar situation in the future. It has been found that patients who have these MRI scans may develop conditions of anxiety such as claustrophobia and panic attacks. The patients who complete the MRI scan successfully reduced their fear of confined places in the future. It was also found that the patients exposed to a confined situation without the possibility of suffocation were only concerned with the fear on confinement, but had no effect on the fear of suffocation. To get the best results for the treatment of claustrophobia you need to address the fear of
