Could the florbetapir f18 injection for pet scan have any possible side effects?

Could the florbetapir f18 injection for pet scan have any possible side effects?

Low Risk - Headache: Florbetapir f18 (trade name amyvid) is a new pet imaging agent that helps to diagnose alzheimer's disease. From the clinical trials, side effects (also called adverse reactions) were quite unusual, with no serious ones. The most common side effect was headache, occurring in 1.8% of the patients. Next was musculoskeletal pain (0.8%), followed by nausea and fatigue (each at 0.6%). ...Read more

Pet Scan (Definition)

Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more

PET scan is the answ: PET scan is a safe test. It is the best test to find out if the nodule in your lung is benign(no PET uptake) or Cancerous(increased PET update also called Hot scan. Your doctor will guide you according to the results of your PET scan. Let us know the result when available. ...Read more

What would cause what appears to be telangiectasias to form on the skin after having a cardiac PET scan/stress test? Is this a common side effect?

What would cause what appears to be telangiectasias to form on the skin after having a cardiac PET scan/stress test? Is this a common side effect?

Don't know - not awa: I'm not aware of any drug that causes telangiectasias other than alcohol. Alcohol will do it over time, and they can appear in clusters depending on the underlying conditions. Go see your doctor or use HealthTap Prime to get more information. ...Read more

Lost about 50 pounds and have tenderness on right side and small lump. Doctor ordered pet scan also said it looks like cancer thank you in advance

Lost about 50 pounds and have tenderness on right side and small lump. Doctor ordered pet scan also said it looks like cancer thank you in advance

Complete the workup: Get the pet scan and any other labs and tests your health care provider thinks are necessary. Unexplained weight loss is a sign of cancer. Lumps and tenderness need to be explained too. Get all the information possible, perhaps including a biopsy, so a proper plan of action can be determined. ...Read more

My husband has a melanoma on the right side of his stomach. Blood work, X-ray and pet scan are normal. Does that mean it is not nessery for a node biopsy?

My husband has a melanoma on the right side of his stomach. Blood work, X-ray and pet scan are normal. Does that mean it is not nessery for a node biopsy?

Not necessarily: The decision to perform a sentinel node biopsy hinges on factors in the original melanoma biopsy and is not affected by "negative" x-rays or scans because only sentinel node biopsy can detect microscopic disease in lymph nodes. ...Read more

Got results for PET scan on lung nodules. Nodules are "undetermined" cuz of size but parotid glands on both side of neck showed "hot". Any relation?

Got results for PET scan on lung nodules. Nodules are "undetermined" cuz of size but parotid glands on both side of neck showed "hot".  Any relation?

No relation: Parotid glands can have chronic inflammation which will show up on a PET scan just like tumors do. But it is unlikely to be anything significant that should worry you. You can ignore it for the time being. ...Read more

What is the question: Currently pet scans are widely use for evaluation of glucose metabolism in the body. In oncology, is use to for initial metabolic characterization of tumors, metastases as well as for treatment response and surveillance. In cardiology, pet scans are use to assess heart ischemia and viability and in neurology the study is use to evaluate cognitive disorders, epilepsy and brain tumors ...Read more

What are pet scans? What exactly is a pet scan?

Positron Emission: These studies are done by injecting a special "dye" that is attached to a specific molecule. Most of the pet today is done using FDG (a glucose/sugar look-a-like molecule). Wherever this molecule is used/concentrated, the pet scan is brighter. Hence, tumors/infections (which use a lot of energy/sugar/fdg) are bright on such studies.

Can someone be with me while I have a pet scan?

Probably: I would not recommend a child or pregnant woman be the companion.The amount of radiation dose is minimal to caretaker as long as has usual distance of 3.5 feet from patient.Study involves injection of isotope and sitting in quiet room for about 45 minutes.Then pet ct scan performed possibly for another half hour. Typical dose would be about 0.13 msv.Round-trip flight from new york to tokyo 0.13msv. ...Read more

Are pet scans accurate or are other scans better?

Are pet scans accurate or are other scans better?

Depends: Depends on what you are looking for. PET scan usually uses a glucose based tracer to evaluate metabolic activity which can be increased in tumors. All modalities have a certain rate of false positives and negatives. Sometimes multiple modalities can each give you different information to obtain a complete evaluation. ...Read more

Physiology of lesion: Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making it hard to see. ...Read more

How many pet scans can a person safely have in 2 months?

How many pet scans can a person safely have in 2 months?

Depends: Radiation received from pet ct is relatively high compared to other imaging tests. Pet ct is mainly used for demonstrating metastatic disease, making decisions about effect of therapy, and looking for recurrence.Pet ct has helped prolong life because it can detect small lesions not seen by other tests. Wise decision should be made judging radiation risk versus positive benefit to the patient. ...Read more

What is the difference between mris & pet scans?

What is the difference between mris & pet scans?

Anatomy vs Physiolog: Mri and ct look at the structure of the body, the anatomy, and the way diseases change or distort it. Pet looks at the physiology, or how the body uses, or metabolizes something. For pet, the most common metabolism pathway looked at is how glucose is used. A low dose ct is often acquired at the same time as the pet (as in pet/ct scan), to correlate the pet findings with the ct anatomy. ...Read more

Why PET?: Pet very valuable study to assess metabolic dysfnctn areas in brain due to many causes, and now we can inject newer chemicals to assess both alzheimer's and parkinson's, but really rather un-necessary and expensive test for stroke, as visualization readily available on an mri. ...Read more

Is a full body pet scan good in the diagnosis of lymphoma ?

Is a full body pet scan good in the diagnosis of lymphoma ?

Very good test: Pet/ct is used quite often in the initial diagnosis and restaging of many types of lymphoma. Lymphoma consumes glucose at a much higher rate than normal tissues. That makes pet/ct with f-18 fdg, which images glucose metabolism, is a great test for lymphoma. ...Read more
