What is the best machine (x-ray, CT scan or mri) to see/identify arthritis? More specifically for hip and back arthritis. Thank you :)

X-ray often good: Each imaging modality has its own strengths and weaknesses. Usually will start with a regular x-ray..Since it may answer the question, is fast, easy and less expensive. If it does not answer the question, a ct or MRI may be needed. The MRI would be the best to see if there is nerve root impingement, and is best for looking at the discs. ...Read more

If somebody had kidney cancer can doctors tell what stage it's in by doing an MRI or cat scan on the patient?

If somebody had kidney cancer can doctors tell what stage it's in by doing an MRI or cat scan on the patient?

Imaging good info: You want to know if imaging studies like ct scan or MRI will help determine the stage in renal cancer. You will get good infrmation from imaging and the staging will be estimated. If the renal cancer extends into the inferior venae cavae or to the right atrium it can be detected by imaging studies. Surgery will confirm the clinical staging.

I'd like to ask can my DEXA scan report be useful to my doctor who want to see my xray. Is DEXA scan serve as a xray ?

I'd like to ask can my DEXA scan report be useful to my doctor who want to see my xray. Is DEXA scan serve as a xray ?

Maybe: Dama: the dexa does take a scan of your bones, but it does not replace a regular x-ray. In fact, often if there is something seen on dexa, a true x-ray will be recommended to further evaluate. On the other hand, the dexa report will give your doctor a good idea of the status of your overall bone health and whether your bones are beginning to thin or not. I recommend that you do the xray too. ...Read more

How often do you need to use PET scan or bronchoscope to locate lung cancer because it does not show on CT scan but symptoms tell you to keep looking?

Clinical judgement: This pathologist is underwhelmed with the health or public benefits of intensive screening for tiny lung cancers. I'd hope that if the person is symptomatic, some other investigations are undertaken and the actual cause gets found. ...Read more

How does an MRI scan work? I have not been able to find much information about MRI scans and i just want to know the basic facts.

How does an MRI scan work? I have not been able to find much information about MRI scans and i just want to know the basic facts.

When : When the MRI (magnetic resonance imaging) was invented it allowed making diagnoses without invading the body much, much easier. A person lies inside what looks like a big donut hole (not the entire body). The MRI machine uses both a magnetic field and radio waves to make detailed pictures of the body. It can show the image of bones, muscles, the brain, internal organs etc. The MRI makes cross-sectional images — so that the body can be examined at numerous depths and levels. Quite an amazing diagnostic tool! ...Read more

What steps are necessary for doctors to diagnose lung cancer?

What steps are necessary for doctors to diagnose lung cancer?

Lung Cancer: Evaluation most commonly includes anatomic imaging (xray, chest CT); tissue sampling (bronch, percutaneous biopsy, surgical resection); and staging (PET/CT, Brain MRI). In addition to this medistinoscopy (surgical eval of medistinal lymph nodes) may be necessary. A team approach between surgeon, medical and radiation oncologists, pathologist, and radiologist should be optimally considered. ...Read more
