A CAT scan may show a lesion on the spinal cord due to various underlying conditions, such as tumors, infections, or inflammation. Lesions can appear as abnormal areas that differ in density from the surrounding tissue, indicating potential issues like demyelination or compression. Further diagnostic tests, such as MRI or biopsies, may be needed to determine the exact nature and cause of the lesion. Prompt evaluation is crucial for appropriate treatment and management.
What else can I help you with?
What is the full form of CAT scan?
A "Computerized Axial Tomographic" scan is a type of X-ray scan that is utilized for diagnostic purposes in a variety of health issues.
Are lymph nodes revealed on a cat scan?
do lymph nodes show on a cat scan
What is a Myocardial perfusion scan used for?
does myocardial perfusion scan show blockage in heart system.
What does a lumbar ct scan show that an mri doesn't?
A lumbar CT scan is particularly useful for visualizing bone structures, making it more effective for detecting fractures, bone spurs, and certain types of degenerative changes in the spine. It provides detailed images of the spinal canal and can also reveal calcifications that an MRI might not show as clearly. Additionally, a CT scan is often quicker and may be more accessible in emergency situations. However, MRI is better for visualizing soft tissues, such as muscles, nerves, and intervertebral discs.
What would a ct scan show in diagnosing PTSD?
yes
Is tethered spinal cord and AVM the same?
== == No.AVM: arteriovenous malformation, which is basically veins or arteries that are not properly formed. This is extremely rare and symptoms don't usually show until the patient is in his/her 30'sTethered Spinal Cord: A disorder caused by tissue attachments that limit the movement of the cord within the column. Causes abnormal stretching of the spinal cord.
What is done in myelography?
In myelography, dye is injected into the spinal canal and the patient is then tilted in different directions on a special table, allowing dye to outline the spinal cord and nerve roots and to show areas of compression.
How long does a spinal cord tear take to heal after blood has been injected into the spinal cord?
It is not certain that full recovery can be made after a spinal cord injury, but stem cell injection therapies have been shown to help in some cases. It can take over 6 months for this therapy to show results. In the case of a blood patch after spinal tap or epidural, the "leak" usually heals itself within a day or two.
How can fat cells be able to help people with spinal cord injuries?
Studies show that fat cells can be changed into nerve cells (by obtaining stem cells from a patient's own fat), thereby possibly helping repair spinal cord injuries.
What is total effacement of csf anterior to the cord?
Total effacement of cerebrospinal fluid (CSF) anterior to the spinal cord refers to the complete loss of the CSF space in front of the spinal cord, typically due to conditions such as a mass effect from a tumor, hematoma, or other lesions. This can lead to increased pressure on the spinal cord, potentially causing neurological deficits. The imaging findings may show the absence of the subarachnoid space normally filled with CSF, which is critical for cushioning and protecting the spinal cord. This condition requires prompt evaluation and management to prevent irreversible damage.
How long does a spinal cord tear take to heal once blood has been injected into the spinal cord?
It is not certain that full recovery can be made after a spinal cord injury, but stem cell injection therapies have been shown to help in some cases. It can take over 6 months for this therapy to show results. In the case of a blood patch after spinal tap or epidural, the "leak" usually heals itself within a day or two.
What is a hypoattenuating lesion in the liver?
A hypoattenuating lesion in the liver refers to an area on imaging studies, such as a CT scan, that appears darker than the surrounding liver tissue due to decreased attenuation of X-rays. This can indicate a variety of conditions, such as cysts, hemangiomas, or metastases, that have different densities compared to normal liver tissue. Further evaluation with additional imaging modalities or biopsy may be necessary to determine the specific nature of the lesion.
A lesion in a blood vessel that show through the skin is called?
vascular lesion
What is the section that demonstrates the continuity between the spinal and cranial cavities?
A midsaggital plane will show the continuity between the spinal and cranial cavities.
What is hemisection of the spinal cord?
hemisection anywhere in spinal cord, and the result is a mixed sensory deficit. you'll lose proprioception (two point discrimination) on the same side as the hemisection. you'll lose pain and temperature sense on the side opposite of the hemisection. depending on level in spinal cord, the effects will be different
Would a ct scan fail to show a malignancy that an mri would show?
Yes, a CT scan can sometimes miss a malignancy that an MRI might detect. This is because MRI provides better contrast for soft tissues, making it more effective in visualizing certain types of tumors, particularly in the brain, spinal cord, and areas with complex anatomy. Additionally, the differences in imaging techniques can lead to variations in sensitivity for specific types of cancers. Therefore, depending on the location and characteristics of the malignancy, MRI may reveal details that a CT scan does not.
Can arachnoiditis show on Mri in the brain as lesions?
Yes, a arachnoidtis will show on an MRI. This will show up on an MRI as a brain lesion, but doctors will furthur be able to determine exactly what the lesion is from.
