Question 1

mri shows three lobulations in bone above knee.  bone scan says everything ok.  how could mri and bone scan show two different results?

Accepted Answer

"Lobulations": is not medical diagnosis or useful information with regard to your MRI results. Please consult with your doctor regarding how your imaging results may (or may not) be relevant to your knee problems.

Question 2

there is increased flow and uptake in the dynamic and blood pool phases of the bone scan of right knee but appears decreased intensity from the prior study suggest hyperemia secondary to inflammatory process. should i be worried?

Accepted Answer

: All imaging and laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. 
Wish you good health!

Question 3

3 phase bone scan, what does it mean? "delayed images photopenic defect is seen of l knee medial compartment arthroplasty hardware. moderate to high grade uptake around tibial component."

Accepted Answer

: It is important to interprete in context of clinical evaluation, however the bone scan is used to measure inflammation because there is increased blood flow to area of inflammation and sometimes inflammation is due to infection. You should follow up with the medical provider so appropriate interpretation and management could be done.

Question 4

what does stable increased flow and uptake of the right knee joint on the triple phase bone scan suggests hyperemia secondary to infection or inflammatory process and bone remodeling or repair and suspect loosening mean. concerning?

Accepted Answer

: I think this report reflects probable ongoing inflammation or loosening of a prosthesis in your knee. I assume you're experiencing significant knee discomfort. Your orthopedic surgeon, who knows your operative history,current symptoms and knee exam findings,  is best to advise you. He/she can also confer with the radiologist who interpreted your study.

Question 5

could a bad scoliosis cause a wrong interpretation of a bone scan, looking for cancer?

Accepted Answer

Unlikely: While the bones scan would likely be abnormal, the reader can interpert based on the obviousfinding, and suggest the prospect whether it is from the conditon or likley to be metastasis.  Mets are usually not just to one bone, but multiple non-adjacent bones, never crossing joint spaces.

Question 6

what's a bone scan for?

Accepted Answer

Cancer or pain: Usually in adults it is used to detect metastatic cancer. It also is frequently used to evaluate for possible stress fractures.

Question 7

how does abone scanwork?

Accepted Answer

Radioactive "dye": A bone scan is usually used to assess the whole skeleton for cancer spread, to look at specific bone sites for fracture or for bone infections.  The patient receives an injection of a radiolabeled substance that is mostly incorporated in to areas of high bone turnover.  A camera to detect the radioactive decay then acts to count the amount of activity.  Areas of high decay are more fully evaluated.

Question 8

what is a bone scan used for?

Accepted Answer

Cancer or pain: Usually in adults it is used to detect metastatic cancer. It also is frequently used to evaluate for possible stress fractures and other bone problems.

Question 9

what do bone scan results tell you?

Accepted Answer

Hot spot, cold spots: The radiologist looks for evidence of abnormal bone metabolism on the scans. These show up as darker "hot spots" and lighter "cold spots" where the tracers have or haven't accumulated.
 
Although a bone scan is very sensitive to abnormalities in bone metabolism, it's less helpful in determining the exact cause of the abnormality.

Question 10

what lights up in a normal bone scan?

Accepted Answer

The bones,: In a fashion similar to that of a skeleton. No areas of "hot spots" or "cold spots".
