An MRI can provide images of your veins that may show if a blood clot has formed. The test uses radio frequency waves and a strong magnetic field to create the images of your veins. MRI image testing does a good job of finding deep vein thrombosis(DVT) in the thigh and pelvis.
CT scans detect and diagnose blood clots by providing detailed, accurate imagery of the body's blood vessels and their obstructions. Doctors generally use two CT scan techniques for blood clot detection and diagnosis — CT venography and CT pulmonary angiography.
The rate of missed diagnosis of lower-limb DVT by ultrasound amounts to 50% or so in patients without symptoms of DVT.
MRI or CT scan: These imaging tests can provide visual evidence of the blood clots.
CT scan of the head, abdomen, or chest, may be used to confirm that you have a blood clot. This imaging test can help rule out other potential causes of your symptoms. Magnetic resonance angiography (MRA) is an imaging test similar to a magnetic resonance imaging (MRI) test.
These include headaches, seizures, confusion, weakness involving one side of the body, and problems with speech. A stroke — a blood flow blockage within the brain that begins to kill brain cells — can cause similar symptoms.

Duplex ultrasonography is an imaging test that uses sound waves to look at the flow of blood in the veins. It can detect blockages or blood clots in the deep veins. It is the standard imaging test to diagnose DVT.
Symptoms of Deep Vein Thrombosis
One of the problems in diagnosing DVT is that many people develop the condition without any symptoms. This usually makes the condition go undetected for a very long time.
Some people may have a blood clot without noticeable symptoms. But if you do have symptoms, they may depend on where in your body the blood clot is located, whether the arm/leg, lungs, heart, or brain.
“But about 30–40% of cases go unnoticed, since they don't have typical symptoms.” In fact, some people don't realize they have a deep vein clot until it causes a more serious condition. Deep vein clots—especially those in the thigh—can break off and travel through the bloodstream.
1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug." 3) Activation of the coagulation cascade.
The primary treatment for DVT and PE is anticoagulation with blood thinners. These medications increase the time it takes for blood to clot. They prevent new clots from forming and existing clots from growing larger. Anticoagulants do not dissolve a clot.
Typically, your body will naturally dissolve the blood clot after the injury has healed. Sometimes, however, clots form on the inside of vessels without an obvious injury or do not dissolve naturally. These situations can be dangerous and require accurate diagnosis and appropriate treatment.
Warm skin. The skin around painful areas or in the arm or leg with the DVT may feel warmer than other skin. Trouble breathing. If this happens, it could mean that the clot has moved from your arm or leg to your lungs.
A D-dimer test is used to find out if you have a blood clotting disorder. These disorders include: Deep vein thrombosis (DVT), a blood clot that's deep inside a vein. These clots usually affect the lower legs, but they can also happen in other parts of the body.
Blood clots may not produce visible symptoms. However, symptoms of a blood clot may become visible or palpable, especially if the blood clots develop near the surface of the skin or if they disrupt blood flow deep in an extremity. A hematoma that has formed may cause what looks like a bulging area of the skin.
However, a blood clot that forms in the invisible "deep veins" can be an immediate threat to your life, as compared to a clot that forms in the visible "superficial" veins, the ones beneath your skin.
Standard MRI can't see fluid that is moving, such as blood in an artery, and this creates "flow voids" that appear as black holes on the image. Contrast dye (gadolinium) injected into the bloodstream helps the computer "see" the arteries and veins.
If you receive quick treatment, then the chances of your recovery are higher and you are more likely to survive. There are different emergency treatments, and they depend on the type of stroke. Even a small blood clot in the brain can result in ischemic stroke.
A blood clot in your brain can lead to serious health hazards like brain stroke or brain attack.
