Doctor insights on: Focal Tracer Uptake In Bones

Share

Bone (Definition)

Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more

Q. 1 of 2. Renogran, left kidney. Parenchymal tracer uptake is reduced with negligible wash out. What does it mean?

Q. 1 of 2. Renogran, left kidney. Parenchymal tracer uptake is reduced with negligible wash out. What does it mean?

If I understand the: Question correctly, the left kidney renogram shows decreased uptake of tracer, which means decreased kidney function. The negligible wash out means little urine production, or possibly a blockage of the upper ureter. Please discuss with your doctor, as this appearance needs to be correlated with your medical condition and the reason your doctor ordered the test. ...Read more

Increased tracer uptake in the cervical spine/ body scan. Neck pain associated w/ torn labrum. COPD diagnosis as well. Is this worth a second look?

Increased tracer uptake in the cervical spine/ body scan. Neck pain associated w/ torn labrum. COPD diagnosis as well. Is this worth a second look?

Unclear story: Increased tracer uptake may or may not be pathological- arthritic joints in the neck will commonly have increased uptake. If it is in the vertebral bone itself, that is unusual and would need a "second look". A "torn labrum" would suggest shoulder pathology, not the neck- you may simply have your terms confused. Obviously, you had a test done for a reason so need to f/u with the ordering doc. ...Read more

Hi could you please explain what "moderately intense increased tracer uptake at the L5-S1 level of the lumbar spine and L4-5 level and right hip joint?

Hi could you please explain what "moderately intense increased tracer uptake at the L5-S1 level of the lumbar spine and L4-5 level and right hip joint?

Bone scan?: Did you have a bone scan done? Assuming that is the case, a chemical (tracer) is injected into the body and will "light up" anywhere there is increased bone activity (increased tracer uptake). Causes of intense increased uptake usually are seen with a fracture, some metastatic lesions, and infections of the bone. Moderate uptake can be seen in arthritic joints such as possibly your hip and back ...Read more

What are the risks of getting a bone scan? If I'm allergic to the tracer could I die?

What are the risks of getting a bone scan? If I'm allergic to the tracer could I die?

Possibility of death: Is rather rare from an allergy. Make sure you mention your allergies to the technician/rediologist. There are alternatives tracers which they might be able to. Use. Make sure you tell them. If they don't have alternatives they won't do the test.
Otherwise risk for this procedure are very few.
Good luck. ...Read more

I had a bone scan done recently I'm trying to see what results mean the findings say homogenous uptake throughout skeleton seen what does it mean?

I had a bone scan done recently I'm trying to see what results mean the findings say homogenous uptake throughout skeleton seen what does it mean?

Homogenous = normal: The term "homogenous" means something similar to consistent or equal. If there is homogenous uptake throughout the skeleton it means there are no abnormal areas of "high uptake" or "hot spots" such as bone cancers.
Therefore, homogenous uptake in the skeleton is considered normal. Still, have a discussion with the doctor who ordered the scan as they will have a better understanding of your case. ...Read more

Hi, I had a question. I recently had a whole body Nuclear Medicine bone scan done and the report says "Unremarkable tracer localization is seen in the osseous structures, what does this mean?

Bone scan: The fact that the interpreting md. Stated it appears unremarkable is an indication that your scan is normal. The description about the distribution is the regular venacular describing the normal uptake by the bone (osseous means our bony skeleton) of the material that has been injected. ...Read more

What does radiopharmaceutical uptake from a bone scan mean in layman's terms?

What does radiopharmaceutical uptake from a bone scan mean in layman's terms?

Tracer uptake: Read the report. But it sounds like it means that there is increased bone metabolism at that location. The radiopharmaceutical maps calcium activity (osteoblastic) of the bone. Can have increased metabolism in response to mechanical stress, a fracture, cancer, infection, and miscellaneous reasons. ...Read more

For a bone scan what is the purpose of doing some scans before/during the injection of the tracer? I thought that the scans were after it was absorbed

Easy imaging...: It sounds like you are referring to a three phase bone scan (flow, blood pool, and delayed images). Early images can provide more information depending on what your condition is. Early images are helpful to look for osteomyelitis, RSD, and some other conditions and can help determine if a condition is acute or chronic. ...Read more

What does "uptake" mean on a bone scan as in "mildly increased uptake involving the RIGHT C6-C7 facet joint?

Bone scan: Uptake means there is simply bone turnover or bone production and degradation in the form of cellular activity. Diagnosis includes fracture arthritis infection tumor anything that dynamically affects bone A bone scan is not an absolute and MUST be correlated with a clinical question plain X-rays and a working differential diagnosis. You must speak to the ordering or treating physician!!!! ...Read more

What are the risks of radioactive tracers in bone scans? Is there risk of nephrogenic systemic fibrosis, and should creatinine be checked before test?

No: NSF is a rare condition sometimes associated with gadolinium administration (contrast) during an MRI exam in patients with renal disease. This is not the same radioactive tracer used in bone scans, usually Technesium 99m. As a matter of fact, gadolinium is not radioactive. The amount of radioactive tracer used for a routine bone scan is so small, no significant side effects are expected ...Read more

Positive, intense uptake on bone scan, lose spinal hardware, bone marrow edema, family history, paternal taking Forteo to strengthen bones.?? ideas?

For one: You probably should remove the hardware. Increased uptake is informing you there is bone activity. You don't state on what phase. This could indicate a fracture or infection.... The doctor should have a clinical suspicion of what he is looking for.
If removing the hardware a bone biopsy can be performed if suspecting infection. ...Read more

What does increased uptake around the area of the left acetbulum mean? Have had two hip replacements, last one in 1999. Bone scan shows significant bone lose and CT shows increased uptake around the area of the left acetabulum as well as the femoral comp

Uptake on bone scan: Bone scan after injection of IV radiotracer is sensitive for changes in bone metabolism. Increased uptake is not specific but can be related to infection, fracture, loosening or even tumor. However ct shows anatomy and pathology. The loss of bone can occur from lack of normal weight bearing or disuse.
Demineralization around stem of prosthesis can be loosening. You should consult your doctor. ...Read more

See specialist: Your best option is to see an ORS who is a tumor/ reconstructive surgeon. There are several centers in Canada and many in the U.S.You want a surgeon who has done this surgery before (if needed). They can also determine if this benign bone tumor is the cause of your pain and your options. Best of luck! ...Read more

What can I do if my latest bone scan shows results in both focal and linear areas, what is the difference?

Many possibilities.: It depends why you had your bone scan done. Focal lesions means "localized" and can have various shapes (circular, linear.) and various localizations. A linear lesion usually means a fracture or compression such as seen in the vertebral column. These are two different descriptive terminologies. Again, it should be easier to respond to your answer if we had the results of your scan. Good luck. ...Read more

What is mild lateral excursion to the patella with focal subchrondral bone marrow along the median ridge inferior patella? Overlying chondromalacia

Weak VMO-LrgQ angle: The VMO ->the medial part of quadriceps muscle, when relatively stronger, it can help your patella (knee cap) track in the middle of its groove. As you grow, hips get wider and that increases the Q angle (look it up). Strengthen your VMO with Quad Sets. Put a Coffee can under your knee straighten- hold.

8.5 yrs daughter with bone age of 11.5 yrs. Mri: diffused enlargement of pituitary gland 10.5x7.3x7.8mm with no focal lesion. How abnormal is the size

8.5 yrs daughter with bone age of 11.5 yrs. Mri: diffused enlargement of pituitary gland 10.5x7.3x7.8mm with no focal lesion. How abnormal is the size

A bit tricky: The pituitary grows during childhood and peaks in the 2nd or 3rd decade. Most studies measuring pituitary size on MRI focused only on the height of the pituitary gland and find that the mean peak height is usually about 6 mm +/- 1 mm. More recent studies measure the actual volume of the pituitary with special 3d mri. The mean volume for 5-9 yo girl in one study was 336+/-113 mm3. ...Read more

Had anterior labral focal depression of shoulder bone &got repaired through binocular surgery, now when I do shoulder exercise spring like sound comes?

Focal scarring: I believe the labrum probably has some scar tissue associated with the original injury, and there is bound to be some scarring from the surgery itself. If there is no pain or limitation of range of motion, the noise should not be a concern, only a side effect of injury and surgery. If there is pain or a limitation to your use of the shoulder, see an ortho and get an MRI to investigate ...Read more

This is my X-ray diagnostic "no focal bone lesion, thoracic vertebral body compression fracture, degenerative bony lipping or disc height loss is see?

That is normal: The radiologist when they read a film will often say what they don't see to show that they looked for it. A focal bone lesion is a tumor or fracture. A compression fracture is a fracture from trauma or osteoporosis. Disc loss height and degenerative body spurs are signs of arthritis. So what you quote here is the radiologist saying that they do not see any of that. ...Read more
