What is super scan in bone scan?
A bone scan in which there is excessive skeletal radioisotope uptake in relation to soft tissues along with absent or faint activity in the genitourinary tract is known as a ‘superscan’.
What is a Superscan in nuclear medicine?
A superscan is defined as a bone scintigraphy which demonstrates markedly increased skeletal uptake relative to soft tissue and is usually with absent or faint genitourinary tract activity.
What is the difference between a bone scan and a nuclear bone scan?
Overview. A bone scan is a test that uses nuclear imaging to helps diagnose and track several types of bone disease. Nuclear imaging involves using small amounts of radioactive substances (radiotracers), a special camera that can detect the radioactivity and a computer to see structures such as bones inside the body.
How many types of bone scans are there?
There are two main types of bone exams. A three-phase bone scan is a nuclear imaging test that shows how the bones process an injected agent. A DEXA bone scan is a type of X-ray that tests bone strength and density to diagnose osteoporosis.
What is flare phenomenon?
The flare phenomenon is defined as bone-scan and serum alkaline phosphate (ALP) findings that show disease progression after treatment despite indications of a good therapeutic response in terms of clinical symptoms or decreased tumor size on computed tomography (CT) scans.
What do they inject you with for a bone scan?
They give you an injection of a radioactive liquid called a radionuclide or radioactive tracer. They inject it through a small tube (cannula) in a vein in your arm or back of your hand. It’s a small amount of radiation.
What is a full body bone scan called?
A nuclear bone scan is a medical test that uses a small amount of radioactive material to check the condition of your bones. It’s also known as skeletal scintigraphy. You probably think of radioactivity as something to avoid. But in a medical setting, radioactive material can tell you important things about your body.
Why is scintigraphy used?
A procedure that produces pictures (scans) of structures inside the body, including areas where there are cancer cells. Scintigraphy is used to diagnose, stage, and monitor disease. A small amount of a radioactive chemical (radionuclide) is injected into a vein or swallowed.
How is renal bone disease treated?
How can you treat renal bone disease?
- Eat a diet that is low in phosphorus. A dietitian can help you make an eating plan that is low in phosphorus.
- Take a medicine called a phosphate binder.
- Take vitamin D and calcium pills.
- Take medicine to control your parathyroid glands.
- Exercise to strengthen your bones.
How is renal osteodystrophy treated?
The major treatment modalities for renal osteodystrophy include phosphate binders, vitamin D compounds, and calcimimetics. Aluminum-containing phosphate binders have been shown to be toxic to bone secondary to their effects on bone turnover, mineralization, and bone volume.
What are bone flares?
Purpose: The bone scan flare phenomenon, defined as an increase in the number or intensity of bone lesions with subsequent improvement while the patient is receiving chemotherapy, has been described in solid tumors including breast cancers and small-cell lung cancers.
How long does flare phenomenon last?
As it can be misinterpreted as progression in bone metastasis, follow up bone scintigraphy for 6 months or more is the rule. If there is a subsequent decrease uptake in these lesions on repeat exam in 2-3 months, it then likely represents a flare phenomenon.
Is a bone scan painful?
While the bone scan itself causes no pain, having to lie still for the length of the procedure might cause some discomfort or pain, particularly in the case of a recent injury or invasive procedure such as surgery.
