Could MRI or CT scan detect brain cancer?

Could MRI or CT scan detect brain cancer?

Sure: Mri would be the imaging test of choice, though often we start with a ct. Ultimately, you'll likely need a biopsy to prove it's a cancer. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Can MRI or CT scan show brain damage from stimulants?

Can MRI or CT scan show brain damage from stimulants?

Stimulants: Stimulants such as Cocaine and amphetamine exert their effects on the user's nervous system and change the user's emotions, behavior, and affects cognition. They may cause miicrovascular ischemic disease of the brain which is unlikely to be detected by MRI or ct scan. ...Read more

Could a mri/ct scan detect all brain injurys?

Could a mri/ct scan detect all brain injurys?

Nope: Sometimes you can see evedence of bleeding. With traumatic brain injury sufficient to cause changes on ct typically survival is markedly reduced. Certain types of MRI done at the right time following a brain injury can sometimes show evidence of cerebral contusion. Much of the damage done with traumatic brain injury is microscopic (too small even with diffuse axonal injury) to be seen on mri. ...Read more

Would a plain CT scan show an unruptured aneurysm in the brain ?

Would a plain CT scan show an unruptured aneurysm in the brain ?

Need contrast: Very difficult to see aneurysms in the brain without contrast. If you are concerned about this as a possibility you should ask your doctor about your risk. ...Read more

Is it possible for MRI or CT scan to detect brain cancer?

Is it possible for MRI or CT scan to detect brain cancer?

Yes: A CT scan can detect a brain tumor, but will be better able to detect a tumor if it performed with IV contrast. Mri with contrast can detect very small tumors that may not be seen with a ct scan. ...Read more

Can CT scan without contrast show any brain tumors?

Can CT scan without contrast show any brain tumors?

Sometimes: Brain swelling, hemorrhage and mass effect can be noted on a head ct without contrast. Also, some tumors have calcification a which can be seen in a head ct. Smaller and lower grade tumors can sometimes be missed on a head ct without contrast. ...Read more

Can a CT scan without contrast dye detect brain tumours?

Can a CT scan without contrast dye detect brain tumours?

Should do it: If a brain tumor is causing significant symptoms, it should surely be large enough to be detected on a cat scan. ...Read more

Can CT scan without contrast show brain aneurysm?

Unlikely: Ct scan without contrast is unlikely to show an aneurysm unless it is very large and is calcified. A ct angiogram is a better study to visualize an aneurysm. ...Read more

Ct scan can reveal a brain tumour and an MRI showed nothing. Which to believe?

Ct scan can reveal a brain tumour and an MRI showed nothing. Which to believe?

Strange: Usually an MRI is more sensitive (better) at detecting rumors than CT. Did the radiologist who read the MRI have access to the CT and its report? It is possible that something that was thought to be a mass on a CT turned out not to be one on MRI. ...Read more

Can a CT scan of the head without contrast dye detect brain aneurysms?

Can a CT scan of the head without contrast dye detect brain aneurysms?

Yes: While plain ct scan is not the best test for aneurysm, large aneurysms can potentially be spotted. Mri is a better test, especially when blood vessels are looked at as well. ...Read more

Does getting an MRI reveal brain tumors?

Does getting an MRI reveal brain tumors?

Usually: An MRI is probably the best way to detect a brain tumor in a patient who has symptoms or findings on a medical examination that suggests a brain tumor may exist. Getting an MRI if you are asymptomatic(have no medical issues) is unwarranted and should not be done. ...Read more

Would a spinal Tumor show on an MRI scan?

Would a spinal Tumor show on an MRI scan?

Usually: Sometimes a spinal cord tumor, especially with extrinsic compression, can result in false localizing clinical signs, which could result in imaging at wrong level, but if precise, the MRI will show lesion. However, you say that you have B-12 issues, and this can cause spinal cord problems in posterior columns, which are also seen on MRI. Do you feel Concierge visit might help? ...Read more

Does a CT scan without dye detect an unruptured brain anuerysm?

Does a CT scan without dye detect an unruptured brain anuerysm?

Not likely: Most intracranial vascular anomalies, including aneurysms, require IV contrast to be seen on ct head. However, ct without contrast is 90% sensitive for intracranial bleeding. The risks of IV contrast for ct include kidney injury and allergy to contrast dye. Good luck! ...Read more

Can a CT scan detect brain aneurysms?

Can a CT scan detect brain aneurysms?

CT angiogram: A regular ct scan might detect a large aneurysm with calcium. A test that is designed specifically to look for aneurysms is the ct angiogram. With this test contrast goes into the vessels of the brain. If there is an aneurysm that is larger than 2 mm, it should be detected with this technique. ...Read more

Would a brain MRI without contrast show everything?

Would a brain MRI without contrast show everything?

No: Imaging studies do not show "everything". For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine. ...Read more

Can MRI with contrast miss brain tumor?

Can MRI with contrast miss brain tumor?

Best test: An MRI with contrast is the best test to detect a brain tumor. If the MRI did not detect a brain tumor then it is likely either too small to see or there is no brain tumor. ...Read more

Brain Damage (Definition)

Anything that disrupts tissue integrity can cause brain damage: lack of or reduced oxygen (stroke), viamin deficiency, pressure (hydrocephalus, or, bleeding or tumor inside the skull), blunt or penetrating trauma; infection; inflammation (immune system mediated or otherwise); toxins (alcohol, ecstasy, lead, mercury, arsenic, to name but a few); diseases (ms, diabetes, ...Read more
