Why is a PET Scan Important?
A PET scan is a very crucial medical and research tool that has revolutionized the administration of health care to the sick. This form of imaging will always show images of changing functional processes of the body before any other scan such as CT or MRI. This type of scan has been very useful to clinical oncologists who deal with mild to complicated brain conditions. This scan helps oncologists to map the behavior and functioning of the human brain while also registering any alteration that might affect its physiology. The brain scan uses a glucose analog tracer, which is phosphorylated by hexokinase after being consumed by glucose-using cells. Hexokinase is mostly found in malignant tumors that are growing rapidly.

The PET scan allows for the analysis of brain activity through a check on the blood and glucose flow as the two processes work in tandem. The PET scans have been carried out using different radiotracers that allow for the visualization of different neuropsychiatric and neurologic illnesses. Neuroimaging allows for the identification and differentiation of various brain conditions. For instance, the neuroimaging can differentiate between dementia and Alzheimer’s disease. On that note, PET scan can be used by psychiatrists, neuropsychologists, and radio surgeons.
Cardiology and Infectious Diseases
PET scans are very imperative when it comes to the study of cardiovascular diseases, especially atherosclerosis, which can be tested using an 18-F fluoride emission (Joshi et al., 2014). However, the cost-effectiveness of the PET scan is in doubt when compared to other tomographies. The imaging of infections allows for the improvement of treatment follow-up and diagnosis. Through the use of fluorodeoxyglucose (FDG), physicians have been able to image bacterial infections, which allow them to detect inflammatory responses. The mapping of bacterial infections in vivo has improved the treatment of infectious diseases.
My interest in MRI started when I first read the book “MRI, The Basics” written by the author Ray Hashemi. By the time I successfully finished my MRI clinical placement in Tehran University of Medical Sciences, I knew for sure that MRI would be the field I would be choosing to take on. What attracts me most about MRI is how beautifully scientist could create a technology that can take advantage of the magnetic moments of human body for imaging it without any harms of ionizing radiation. Although there are drawbacks to MRI, combining it with other modalities would be a more effective approach to an accurate diagnosis.
The careful familial and patient history is imperative for this exam and procedure. And as the video indicated, is this really an effective screening tool for a healthy person more so than seeing the primary care physician. According to the research in the Indian Journal of Medical Research, the “PET/CT doses were found to be higher than many other conventional diagnostic radiology examinations suggesting that all efforts should be made to clinically justify and carefully weigh the risk-benefit ratios prior to every 18FDG whole body PET/CT investigation” (Kaushik et al,
As an ultrasound technician/sonographer I will have the ability to see dangerous defects within the human anatomy and begin a lifelong profession with many benefits. The Ultrasound was first invented in the early 1900’s and was surprisingly not used to produce photos of a fetus. In 1917 Paul Langen a marine life scientist used a form of ultrasound equipment in his attempt to detect submarines. After many failed attempts at using high frequency sound waves Dr. Ian Donald and his team in Glasgow, Scotland invented the first ultrasound machine in 1957. Dr. Donald even tested his machine on patients within a year of completing the invention, by the late 1950’s ultrasounds became routine in Glasgow hospitals.
Doctors need a sure way to diagnose the disease before treatment or studies can be done. The diagnosis is an autopsy of brain tissue examined under a microscope. In addition, medical history, a physical exam, and mental status tests are used for diagnosis (Posen, 1995). Often, tests are done to rule out other potential causes of the dementia. This allows the identification of other causes of thinking and behavioral changes to be made before concluding that the patient has Alzheimer’s or another form of dementia. The tests that are requested to be done include CT and MRI scans to rule out strokes or brain tumors which could account for change in memory and behavior; thyroid and psychological tests which can also detect thinking and behavior problems (Posen, 1995).
How does radiology help in the medical field and everyday life? In the medical they use it in dental, doctor offices, they can also use radiology when they give a live injection into the human body. How do they use radiology in everyday? When you live at the beach and water table is high you have to call someone first to come and X-ray of ground to make sure you're digging down to the water table or you digging up lines or other
The dream that I most desire in life is to become a Diagnostic Medical Sonographer. I’ve always had an interest in the inner workings of the human body, but I also value life, and care for others, and my happiness is the happiness of others. Although this career has its bumps on the road just to see mothers face light up when they see the image of their unborn baby is such a breath taking experience. This all originated from going to one of my sisters’ ultrasound appointment that I ended up going to all my sisters’ ultrasound appointments. I believe becoming a diagnostic medical sonographer is something I can do because I have what it takes. Diagnostic medical sonographer is imaging modality that can work in conjunction with other imaging modalities
Do diagnostic Medical Sonographers actually help begin a new life? Yes, according to researchers they do help patients indicate any problems that there may be and what may be expected. This essay will talk about Diagnostic Medical Sonographers and everything it takes to become one and how to become successful as well as why they are important to our global community. Sonographer’s are also known as ultrasound Technicians, they are very important in the medical field because they help patients and physicians diagnose and treat diseases as well as other medical information. The following paragraphs will talk about the information of the Salary and also the Job Responsibilities. With the technicians continuously providing
Ultrasound Technicians are very valuable in the world of health care. Also known as Diagnostic Medical Sonographer, an Ultrasound Technician uses special machines and equipment that operates on sound waves to determine or diagnose medical problems for patients. There are specializations within this field in which some individuals explore. For instance, areas of specialization includes but not limited to; pregnancy, heart health, gynecology, and abdominal sonography. Although each specializing branch has its own distinctive function, they all involve probing the body to facilitate doctors with diagnoses.
I am a patient and caring person who enjoy helping people. My ambition to become a Diagnostic Imaging technologist developed when I was working at Queen Elizabeth University Hospital in Glasgow. During this time, I worked as a temporary support worker who helped patients to attend their scheduled medical examinations at the Imaging Department.
Other problems with using these noninvasive imaging methods of only few changes of variables in the brain’s activity are that maybe the problem does not reside in the blood, oxygen intake, or glucose utilization. It may be in other factors that we do not observe that is causing the trouble. By being limited to these estimations of brain activity does not really make our effort of correcting the problem that successful.
The training, experience and interests during my existence up to now happen to be quite varied. I've resided and labored in Germany, The country and France too as with the United kingdom. Lately, I've thought extensively about altering my career and been attracted to radiography because it offers attractive possibilities to use abilities and private characteristics which i consider I possess, to supply an immediately tangible and satisfying contribution to individuals??utes health.
When it comes to many things in the medical field there will always be a potential health risk involved in the treatment and diagnosis that will be beneficial to the patient. This is including things from prescription drugs to anything used to diagnose a medical issue. Diagnostic imaging has many modalities and is often used to diagnose many issues that include fractures, diseases, tumors, and cancer. Computed Tomography (CT), which uses radiation exposure, is one of the diagnostic imaging modalities used to detect and diagnose the medical issues previous listed and more. Computed Tomography comes with some potential health risk but also many medical diagnostic benefits.
Radioisotopes have helped create advanced imaging techniques. Beforehand, X rays could only provide so much information such as broken bones, abnormal growths, and locating foreign objects in the body. Now it is possible to obtain much more information from medical imaging. Not only can this advanced imaging give imaging of tiny structures in the body, but it can also provide details such as cancerous cells and damaged heart tissue from a heart...

Positron-emission tomography (PET) is a nuclear medicine imaging modality which detects gamma rays emitted by a positron-emitting radioactive tracer. The most common tracer used for neuroimaging is 2-deoxy-2 (18F) fluoro-d-glucose (FDG). It approximates for the metabolic processes in the brain providing a broad range of functional and metabolic information to help understand mechanisms of neurologic diseases and guide therapeutic approaches. Most settings have used 2-deoxy-2 (18F) fluoro-d-glucose (FDG) in the interictal state [35,47]. Ictal PET is not of much help as the half-life of radiotracer used extremely short. For patients with temporal lobe epilepsy interictal studies shows hypometabolism in epileptogenic areas. Interictal FDG-PET provides more information about epileptogenic foci compared to
