Introduction

A positron emission tomography Shaquille O’Neal Jersey , also known as a PET scan, uses radiation to show activity within the body on a cellular level.

Positron emission tomography (PET) is being increasingly used for diagnosis, staging, and follow-up of various malignancies. It has been studied in the evaluation of various tumors including but not limited to solitary pulmonary nodules, non鈥搒mall cell lung carcinoma, lymphoma Terrell Brandon Jersey , melanoma, breast cancer, and colorectal cancer.

Combined with a CT or MRI scan, a PET scan can produce multidimensional, color images of the inside workings of the human body.

It is most commonly used in cancer treatment, neurology Jordan Clarkson Cavaliers Jersey , and cardiology.

It shows not only what an organ looks like, but how it is functioning.

A PET scan is used to diagnose certain health conditions, to plan treatment, to find out how an existing condition is developing, and to see how effective a treatment is.


Facts on PET CT Scan

Here are some key points about PET scans. More detail is in the main article.
鈥?PET scans are often used to diagnose a condition or to track how it is developing.
鈥?Used alongside a CT or MRI scan, it can show how a part of the body is working.
鈥?PET scans are often used to investigate epilepsy George Hill Cavaliers Jersey , Alzheimer's disease, cancer, and heart disease
鈥?A scan is not painful, but patients should not consume any food for at least 4 to 6 hours before a scan. They should drink plenty of water.
Uses
PET scans are often used with CT or MRI scans to help make a diagnosis or to get more data about a health condition and the progress of any treatment.

While an MRI or CT scan shows how part of the body looks, a PET scan can reveal how it is functioning.

PET scans are commonly used to investigate a number of conditions:
鈥?Cancer
鈥?Heart disease
鈥?Epilepsy
鈥?Alzheimer's disease

How it works

In a PET scan, a machine detects radiation that is emitted by a radiotracer.
A radiotracer consists of radioactive material that is tagged to a natural chemical Kevin Love Cavaliers Jersey , such as glucose.
This radiotracer is injected into the body, where it travels to cells that use glucose for energy.
The more energy a group of cells needs, the more the radiotracer will build up in that location. This will show up on images that are reconstructed by a computer.

The cells, or activity, will show up as "hot spots" or "cold spots."

Active areas are bright on a PET scan. They are known as "hot spots."

Where cells need less energy, the areas will be less bright. These are "cold spots."

Compared with normal cells LeBron James Cavaliers Jersey , cancer cells are very active in using glucose, so a radiotracer made with glucose will light up areas of cancer.

Procedure

A PET scan is normally an outpatient procedure.

Normally, the patient should not consume any food for at least 4 to 6 hours before the scan, but they should drink plenty of water. They may have to avoid caffeine for at least 24 hours before the scan.
First, the doctor will inject a small amount of radiotracer into a vein. The tracer can also be breathed in as a gas, taken by mouth Kyrie Irving Cavaliers Jersey , or injected directly into an organ.

Depending on which the organ is involved, it may take from 30 to 90 minutes for the radiotracer to reach the targeted part of the body.

Meanwhile, the patient will normally be asked to stay still and not talk. Some patients may be given medication to relax.

The patient will probably need to wear a gown, and they may have to remove jewelry.

When the patient is ready, they will be taken to a special room scan for the scan. They will lie down on a cushioned examination table.

The table slides into a large hole so that the patient is surrounded by the machine.

The patient will have to stay as still as possible. They may be able to listen to music.

During the scan, the machine takes images.

Depending on which part of the body is being scanned Jordan Clarkson Youth Jersey , this should take about 30 minutes.

It is not painful. If the patient feels unwell, they can press a buzzer to alert the staff.

A qualified practitioner will watch the patient during the scan.

The entire testing procedure typically takes about 2 hours. Most patients can go home as soon as the scan is finished.
Patients should consume plenty of liquid to flush the radioactive drugs out of their system more quickly. The radiotracers should have left the body completely within 3 to 4 hours.

Conclusion

PET scan with its widespread applications has emerged as an indispensable tool in the detection, staging, treatment monitoring, and identification of recurrent disease in a large number of malignancies.

NEW DELHI, Aug. 19 (Xinhua) -- India's Delhi government has threatened to take over some 449 private schools in the city if they fail to give back "excess fees" charged from students within a fortnight.

Delhi Chief Minister Arvind Kejriwal issued the ultimatum to the private schools Friday evening after a special panel that looked into school fee hike in the Indian capital found many of them had overcharged students over the years and recommended refund of the excess money.

"We are not against private schools, there is no witch hunting. We are appealing to these 449 schools to implement the committee's recommendations and give back extra fees to students within two weeks," Kejriwal told the media.

"The Delhi government does not intend to interfere, but will surely discipline the schools if needed. I hope we don't have to take over. Today, we intend to sen. Cheap Vans Old Skool White   Cheap Vans Old Skool Blue   Cheap Vans Old Skool Pro   Cheap Vans Old Skool Checkerboard   Cheap Vans Old Skool Grey   Cheap Air Vapormax Blue   Cheap Air Vapormax Pink   Cheap Air Vapormax Online   Cheap Air Max 2018 Shoes   Cheap Air Vapormax Online
