Cancer On An Mri
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Is it possible for physicians to miss the dx. Of cancer on an MRI when it has spread all the way to your brain?
Not often: Mri is quite good at recognizing metastatic cancer in the brain, once a tumor had grown to the size at which it can be detected...Usually a few millimeters in diameter. Mri cannot detect microscopic spread. Of course, it is always possible for MRI films to be misread, as those who read them are human and might make a mistake. ...Read more
If someone has pancreatic cancer and an MRI was done that showed a new tumor (liver) does this mean it is always cancerous? Does a biopsy make sense?
Maybe: Every lesion seen doesn't mean its cancer. A biopsy would make sense if you would do something different with either a positive, negative, or non-diagnostic result. If there would be nothing different done in terms if treatment, life planning, etc., twgardless of the result, them don't do it. Hope this helps! ...Read more
I am 30 year male with rectal cancer. Finished radiation. Mri report is "small lymphnode (size 4mm) is seen along inferior mesenteric vessel". What's it?
Most likely LN: This is most likely a lymph node (you can also feel them in the groin and neck areas0. 4 mm is indeterminate in size (thus within the range of sizes for a normal lymph node). The only way to know if it is connected with the cancer is a followup MRI in 4 to 6 months to see if it is getting bigger. ...Read more
If I get to many CT scans are x rays. Will I get cancer eventually? And MRI s use magnets so they are fine right? And all with the contrast.
I have normal cervix after pap test, I've endometriosis. Now normal left ovary, Rt. Ovary contain 100mm cyst Very afrid, may I have cancer? Next week MRI
What test is best to rule out lung cancer or lukemia? MRI with contrast or pet scan? Been having heavyness weak pulse for 6 months
Tests: The best test to screen for lung cancer, in my opinion, is a chest ct scan as a conventional chest xray can miss it. A simple blood test, cbc and differential, is adequate to screen for leukemia. These are screening tests but a tissue diagnosis is required in most cases for a definitive diagnosis. Your pulse description is nonspecific. An MD can check your bp and pulse to look for abnormalities ...Read more
Could a CT scan without contrast (allergy) be effective detecting lthymoma or small cell lung cancer or could mri no contrast be as good as CT.
Can CT scan miss lung cancer? Can an MRI find it while doing scan on thorastic spine? Both without contrast
No symptoms. 62 yr female, shadow chest xray breast region. No fam hist of breast cancer. Will have MRI, but anxious about possible explanations other than breast cancer? Smoker, has/had fibrocystic breasts.
My former endocrinologist told me that I was likely going to develop cancer from several mris I have had to follow a pituitary adenoma and benign liver tumor. Are mris causing cancer in patients?
Nonsense: Mris use powerful magnets to harmlessly and temporarily change the orientation of atoms in your tissues. They then use radio waves to visualize the image. The change of atom spin and orientation has no effect on the molecules or their function. The type of radiation that causes cancer is ionizing radiation. You get exposed to that with ct scans, xrays, air travel, etc. But not mris. Fear not. ...Read moreSee 2 more doctor answers
Is there any possible way that my doctor could have mistakin cancer on an MRI of my upper back for arthritis?
Not likely: I understand your concern as I assume you are having significant pain in your back. However, cancer and arthritis usually appear very different on mris. First, tell your doctor (who ordered the mri) about your concern about cancer. He or she may view the MRI personally or ask a second radiologist to check again for the possibility of cancer. Cancer is always looked for in cases of back pain. ...Read moreSee 2 more doctor answers
I have middle back pain that doesn't start hurting until I am up a while. I had mri. If I had cancer would MRI caught it?
YES IT WILL:
The pain comes after you are up and about. It is more likely to be muscular but it may be originnating from the spine but unlikely
mri will show the bones and if there is herniated or bulging disc ot spinal stenosis.Consult your doctor, it is very unlikely that you have cancer but have it checked by your doctor. ...Read more
What's better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.
What's better for diagnosing pancreatic cancer? Ct scan or mri? 34yr male. I've had normal ultrasound and CT scan with contrast. Still worried.
CT, ERCP, MRCP: Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures... Blood tests including tumor markers: ca-19-9, ca-15-3, and CEA can alert the clinician for ca. Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy. Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority. ...Read more
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
