Will MRI scans show cancer?

Will MRI scans show cancer?

Depends: Mri is very good at showing abnormal tissue from normal tissues and can pick up various cancers very well. Some cancers, however, can be small and not well seen on mri. Some may be better seen on ct. Cancers involve in the stomach and colon are usually not well seen and may require endoscopy or colonscopy. Some breast cancers are also better seen on mammograms than mri. ...Read more

Mri (Definition)

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

Mri shows benign looking 1.6 cm supraclavicular node-dr recommends I see hemotologist oncologist. Possibly malignant even if benign looking? Lymphoma?

Mri shows benign looking 1.6 cm supraclavicular node-dr recommends I see hemotologist oncologist. Possibly malignant even if benign looking? Lymphoma?

Excision.: If this node is easily accessible, then it should be removed for definitive diagnosis. Tests like ultrasound and MRI can suggest benignity or malignancy, but taking it out and sending it to the lab would give us the most accurate and reliable answer. Bring the MRI to a surgeon and see about having it removed. ...Read more

Atypical hemangioma on spine MRI. Why spine MRI can't determine cancer? Full-body scan recommended but how about whole-body MRI to avoid radiation?

Atypical hemangioma on spine MRI. Why spine MRI can't determine cancer? Full-body scan recommended but how about whole-body MRI to avoid radiation?

Not performed.: Contrary to what you might have been told, a "whole body MRI" is almost NEVER performed - it's too expensive, & the technology doesn't work to make it easier. A PET or PET/CT scan is a better test for detecting cancer, but unless you have SYMPTOMS indicating cancer, the chance of picking something up is remote. It wastes your time, worry, & money. Hemangiomas are common. TTYD or use HealthTap Prim ...Read more

Mammogram with punctate pleomorphic calcifications. Is that breast cancer?

Mammogram with punctate pleomorphic calcifications.  Is that breast cancer?

Needs investigation: Although breast calcifications may not necessarily mean cancer, pleomorphic calcifications are suspicious. A biopsy should be done. Talk to your doctor. Pleomorphism means that something is of varying shape and characteristics. A non-cancerous or benign calcification will be read as "benign-appearing". Don't delay your biopsy. ...Read more

Breast tumor biopsy revealed 'canercous change'?

Breast tumor biopsy revealed 'canercous change'?

Need more info: "cancerous change" can mean many things. There are different pre-cancerous changes seen on breast biopsies, such as ADH (vasopressin) or alh (atypical ductal or atypical lobular hyperplasia). There are early cancers called dcis or lcis (ductal carcinoma in situ or lobular carcinoma in situ). Hopefully this is nothing, but we need more information. Make sure to follow-up with your doctor! ...Read more

Malignant melanoma causing hot spots on bone scan?

Malignant melanoma causing hot spots on bone scan?

Possible: Melanoma does have the ability to travel to bone and would show up on a bone scan. However other processes (non-malignant) can also also light up on a bone scan. Only a biopsy could tell for certain. ...Read more

Mammo:ill marginated focal assymetry, sono:two lipomas or intramamary lymphs, mri:looks benign but birads 4, and recommends biopsy.Im confused/scared!

Seek expert opinion: I would advise that you consult a breast cancer surgeon or medical oncologist who has reputation of being a specialist in breast diseases/cancer. Based on your history, you may need to have a biopsy of the lumps/masses/ shadows that you have mentioned. That is the final solution to any palpable/visible lump in the breast. This will remove your anxiety which is due to the uncertainty you are facin. ...Read more

They can: The diagnostic yield of increased with use of IV contrast material as some tumors disrupt the so called blood brain barrier affording the contrast the ability to infiltrate from the blood stream into the tumor. Small tumors that have not disrupted the integrity of blood vessels may escape detection on CT especially if the have the same radiographic tissue density as their surrounding tissue. ...Read more

Could heart MRI detect breast cancer?

Could heart MRI detect breast cancer?

It is: possible, but a cardiac MR is not optimized for breast evaluation, so breast cancer detection on cardiac MR is likely to be accidental and imprecise. It cannot substitute for the standard breast imaging techniques such as mammography, sonography, and breast MR. ...Read more
