PET Scans Essay example

Role and Side-Effects of a PET Scan As a diagnosis and imaging procedure, PET has many uses in the medical field [23]. Its most common utilization being related to oncological detection [23]. However, a PET scan is also used to determine the malignancy of a tumor, or to establish the stage that a particular cancer has reached [23]. This information is ascertainable due to observations about the metabolic uptake of the glucose radiotracer [23]. A PET scan is utilized to detect all types of cancers

The technology that is being investigated is the PET scan. The PET scan functions as a result of the specific atomic properties of positrons which are subatomic particles that have the opposite charge of electrons but the same mass. The PET scanner detects these positrons which are emanated by the radioactive chemicals attached to a chemical the body naturally metabolizes (Positron Emission Tomography, 2014). The PET scan is used in the fields of oncology, neurology, and cardiology to determine the

Positron-Emission Tomography (PET scans) Positron-Emission Tomography (PET) scan is a medical test that allows doctors to check the human body for any diseases. Doctors use the PET scan for many things, the main uses are checking for cancer, heart-related (Cardiovascular) diseases and brain (neurological) diseases. It also allows doctors to check organs and tissues and to see how they are working. PET scanners are a way of tracking diseases, using radioactive tracking that is injected into a vein

PET Scan Diagnostic Imaging is extremely relevant in today’s medical treatments. Doctors have a variety of different imaging and scans techniques that help diagnose, evaluate, and treat patients. The PET scan stands for Positron Emission Tomography and is a nuclear imaging test that shows metabolic activities of the brain. Unlike a CT, MRI and X-ray that scan to image the anatomy of the brain the PET scan image is an image of how the brain is functioning. A PET scan Uses Positron radiation combined

POSITRON-EMISSION TOMOGRAPHY SCAN Introduction A positron-emission tomography scan (PET scan) is a machine that is used to discover how organs and the brain work. Although it is mainly used to detect cancer, heart problems and brain conditions. How does it work? A PET scan uses radiation produced from a radiotracer as it gathers in different parts of the body. Most PET scans use a radiotracer called fluorodeoxyglucose (FDG). FDG is similar to that of normal glucose. By investigating where the radiotracer

CC: Followed up PET scan. History of Present Illness: Ms. Dall is a very pleasant woman who has a very extensive smoking history. She has obtained an initial CT scan, which showed a right upper lobe pulmonary nodule. She has subsequent PET scan and she is here today for followup of those results as well as pulmonary function testing. She continues to smoke about a pack a day and is not willing to quit at this point. Medications: 1. Metformin. 2. Pravastatin. 3. Lisinopril. 4. Amlodipine

Interpretation of PET/CT scan There are different methods for assessment of radiotracer uptake by normal and pathologic tissues, such as visual inspection, the standardized uptake value (SUV) and the glucose metabolic rate. Visual inspection in analysis of PET-CT results is used by comparing PET and CT data, as well as viewing fused PET-CT images. SUVs are used for semi-quantification of FDG uptake. Another method of quantification of dynamic PET results is the more complex glucose metabolic rate

Position Emission Tomography (PET). A PET scan measures the blood flow, brain metabolism and glucose intake. During the procedure, the patient is given a harmless dose of a radioactive substance, which is most likely 2-deoxyglucose (2-DG) which is taken up by cells and accumulates in active neurons (Pinel, 2011). The radioactive element releases positrons which are detected by the scan showing which parts of the brain are

refers you for a PET scan, you will be introduced to a fairly new medical imaging technique. Since this emerging modality is so new, a lot of the general public is not aware of what a PET scan exactly is. This essay will help explain the concept of this modality and the characteristics of it that allow doctors to diagnose and manage the proper care for some of today's most devastating medical conditions known to man. Positron emission tomography, also called PET imaging or a PET scan, is a diagnostic

REMISSION, REMISSION, REMISSION = HAPPY ENDING! Well Michelle had her PET scan and a CT scan last Thursday. We thought we had to wait until Tuesday for the results but to our relief the doctor called Friday night to tell us the good news. The tumors had shrunk and Michelle is officially in remission. Well, I went crazy happy but Michelle wanted to wait until we saw the doctor on Tuesday, just to make sure what we heard was right. Well we went to the doctor yesterday and she confirmed that everything
