Not necessarily. Nephrogenic systemic fibrosis (nsf), also known as nephrogenic fibrosing dermopathy (nfd), is a disease of fibrosis of the skin and internal organs reminiscent but distinct from scleroderma or scleromyxedema. It is caused by gadolinium exposure used in imaging in patients who have renal insufficiency.
I am not sure? Scleromyxedemalike skin lesions occur without associated paraproteinemia. Serum protein electrophoresis and immunoelectrophoresis results are negative. Nephrogenic systemic fibrosis (nsf) occurs in the setting of renal disease. Thus, abnormal values of BUN and creatinine are typically present. Thyroid studies produce normal findings in patients with nephrogenic systemic fibrosis.
Affects skin, joints. Nephrogenic systemic fibrosis (nsf) is a serious condition where fibrosis of skin leads to scar-like nodules & plaques. Joints can be affected, leading to contractures & pain. Serious cases can lead to fibrosis of organs. The cause is unknown, but is related to kidney failure & exposure to gadolinium, used in mri. A skin biopsy is diagnostic, showing thickened collagen bundles & sclerotic bodies.
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.
Not likely. The site of biopsy will be sore for a day or two, but you should be able to return to work the day after. More important for your ability to work may be the reason for which you need bone marrow biopsy.
No. No, bone marrow biopsy is taken from the hip bone, they don't go close to the bowels, you should get evaluated though for the bloody stools!
Neither is common. None of these procedures are common and even less common together, however, that does not mean that there was any thing inappropriate in doing the two procedures in one visit. It would depend on what is suspected to be your health issue.
