Does An Mri Show Blood Clots
Does a normal brain MRI without contrast show blood vessel abnormalities or do you need another test like an MRA?
Depends on question: Common misconception: MRI (or MRA) doesn't "see everything". ANY imaging test used to help confirm a diagnosis has limitations & doesn't establish Dx from "thin air". MRI can see SOME of the effects of blood vessel abnormalities (like scarring or infarction) & perhaps large abnormalities like aneurysms, but isn't the best test to determine blood flow. So it depends on clinical question being asked ...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
Not usually: Plain x-ray is not a usual modality to evaluate blood vessels. If by "widening" you mean dilatation or aneurysm, ultrasound is the most common diagnostic tool to start with. However, depending on location of the vessel ct or MRI may be reasonable starting points. Ct does use xray. Angiography is a diagnostic tool I use when treating blood vessel disease and is very good at evaluating as well. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Vein Thrombosis : Brain mr angiogram (mra) and mr venography (mrv) are specifically designed to examine your blood vessels. Mrv is often used to examine the intracranial venous system, particularly in the evaluation of dural sinus thrombosis. Mri in conjunction with mrv is both sensitive and specific enough to provide the best noninvasive method of diagnosing cerebral venous thrombosis. ...Read moreSee 1 more doctor answer
Absence: An ecg/ekg is not really a test of flow--unless you counted the rate and assumed a faster one meant more flow. It better assesses the electrical conduction of/through the heart. Certain rhythms (like atrial fibrillation) are associated with less efficient pumping. An echo would be a better test to examine flow / stroke volume / etc. ...Read moreSee 1 more doctor answer
Can a full blood screen/complete blood count test show if my immune system isn't good? The doctor mentioned white blood cells would show something?
CBC: Your complete blood count measures the number and type of white blood cells, which are an important part of your immune system. If they are normal, you are unlikely to have a significant immune system problem (there are rare immune system abnormalities that do not show on your cbc). ...Read more
Tell us more details: Where is the blood clot? Is it in the leg or in the lungs? The disease process of clots is called dvt. Most times DVT occurs without a clear cause. But pateints with occult cancers can, sometimes have a blood clot. Most doctors would screen you for any cancer in your body by doing a ct scan of abdomen and a chest x-ray, besides a good physical exam. Pet scan is another good cancer screening test. ...Read more
Would a Contrast-enhanced CT pulmonary angiogram also show lesions, abnormalities, masses, nodes, etc. of the lung or does it only show the blood vessels? (Basically, does it provide more or less information than regular Chest CT?)
Cancer/ inflammation: Both cancer and noncancerous inflammatory conditions like diverticulitis can cause obstruction of the colon and symptoms associated with that obstruction. During colonoscopy, the obstruction will not allow the colon to distend properly allowing the operator to visualize the problem and biopsy any abnormality. ...Read moreSee 1 more doctor answer
Think about it, Remy: Whatever would you do brain MRIs for if they didn't show "damage"? The difficulty here lies with your terminology. Brain "damage" is so vague as to be essentially meaningless. MANY disease processes can afflict the brain, & the MRI appearance of "damage" is distinctive depending on the kind of "damage" it is. Neuroradiologists interpret the "damage" all day long. I'm very grateful that they exist. ...Read more
