Had blood clots in lungs2012, why does it still show up in my MRI? Does it ever disappear.?

MRI?: Pulmonary emboli are uncommonly seen on MRI but are commonly detected with ct pulmonary angiogram. Most emboli resolve though sometimes there are changes detected in the involved arteries suggesting previous clot. If clot is seen in the same artery one year later it is worrisome for a new embolus. Bottom line, you need to discuss this with your doctor until you understand. ...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

Can MRI contrast cause blood clots in people with hyper coagulate disorders?

Can MRI contrast cause blood clots in people with hyper coagulate disorders?

Extremely rare : The contrast is very unlikely to cause a blood clot. However, the venipucture used to administer the contrast could very slightly increase the risk of a clot at/near the site of the procedure if someone is hypercoagulable. ...Read more

Hi my thigh is swollen has been since February. Been to my doctor in March they did a mri to check for blood clots And it came back negative.?

Swelling: A venous ultrasound is the test done to check for blood clots. An MRI of the thigh, if negative, is reassuring that there is no tumor. If thigh swelling persists, consult an orthopedic surgeon. ...Read more

Would a Mri without contrast and a Mra show a blood clot in the brain?

Would a Mri without contrast and a Mra show a blood clot in the brain?

Both can be useful : MRI of the brain can be useful to demonstrate the territory of the brain affected by the stroke. MRI without contrast can indirectly show clot in the brain. MRA of the brain will potentially show clot. This is typically done in conjunction with MRA of the neck. ...Read more

Would an MRI or mra of the brain show a blood clot forming, or stroke risk?

No: It is not a useful test for looking at the caliber of the artery to assess for risk of stroke or forming a blood clot.
Ct angiography or cerebral angiography would be better tests for this problem. ...Read more

I have a blood clot in my right atrium attached to the catheter on my chemo port. Have had multiple TEEs. Is MRI a better way to tell what it really is?

I have a blood clot in my right atrium attached to the catheter on my chemo port. Have had multiple TEEs. Is MRI a better way to tell what it really is?

No. Ultrasound.: In all likelihood, the MRI won't reveal any more information than what ultrasound has already determined (TEE is a type of echocardiogram or ultrasound of the chest). TEE checks for migration (movement) of the clot & it's size. An MRI is an expensive way to do that; TEE is "as-good". If you're being treated w/ blood thinners, stay the course for 6 mo as clots can take long time to shrink. Patience ...Read more

Sprained ankle in March, RICE /walking boot for a month. Had Xray, no breaks.MRI to check for blood clot that was negative.outer ankle still swells.

Sprained ankle in March, RICE /walking boot for a month. Had Xray, no breaks.MRI to check for blood clot that was negative.outer ankle still swells.

I never really : Heard of anyone getting an MRI to check for blood clots. Usually a venous duplex ultrasound or even a d dimer blood test would be ordered to rule out a clot. The MRI would be ordered to assess for structural damage and could explain the swelling, having said that some swelling one month after an ankle sprain is not uncommon. Wear some type of compressive anklet while walking. ...Read more

Muscular: It sounds like a muscle issue. I'm not sure why a brain or throat MRI would be done for upper arm problem. If it is painful or affecting your function, I would have it checked out again. ...Read more

Do blood clots in the lungs show up in the lungs in a xray as well as nuclear scan?

No: Very rarely a chest x-ray can show typical signs of plumonary emboli. Chest-x-ray is performed to rule out other causes of symptoms such as pneumonia or pleural effusion. Ct with contrast agent or v/q lung scan with radioisotopes inhalation and intravenous injection are the most common methods for diagnosing pulmonary emboli. ...Read more

2 weeks after outpatient orthoscopic surgery for medial meniscus tear should I still be concerned about blood clots? Can CT scan show clot?

2 weeks after outpatient orthoscopic surgery for medial meniscus tear should I still be concerned about blood clots? Can CT scan show clot?

Usually not unless..: Arthroscopic knee meniscectomy surgery is a relatively quick, benign procedure. It is performed at times with a tourniquet. Blood clots rarely occur after it. Some people have predisposing factors (smokers on birth control bills, clotting disorders). Keeping the leg active can prevent it as well as taking baby aspirin. Ultrasound evaluation is best for diagnosing a clot. If concerned c your doc. ...Read more
