Will a CT scan of the lumbar spine post fusion without contrast show pinched nerves or just bone structure and hardware?

Will a CT scan of the lumbar spine post fusion without contrast show pinched nerves or just bone structure and hardware?

Limitations: No, a better view of nerve compression will be available if MRI is chosen, but the CAT does reveal nice images of fusion integrity, and surrounding vertebral bodies and foramina. ...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 of the lumbosacral spine show infection without contrast?

Can MRI of the lumbosacral spine show infection without contrast?

Yes. MRI does not : Need contrast enhancement and is a great imaging device for making a diagnosis of infection inthe spine whether it involves bone ( osteomyelitis ), disc ( discitis) or an epidural abscess. ...Read more

My MRI report say this: levoconvex curvature of the lumbar spine. The spinal cord terminates at the inferior aspect of the t12 vertebral body.Meaning?

My MRI report say this: levoconvex curvature of the lumbar spine. The spinal cord terminates at the inferior aspect of the t12 vertebral body.Meaning?

Doctor speak: We need to sound smart. It basically means a bit of a scoliosis i the lower spine with the apex of the curve pointed to the left. The spinal cord is ending at the bottom of the last thoracic vertebrae, which isn't to far from normal. Speak to your doctor and they can likely go over the actual films with you and show you what they mean. ...Read more

MRI of lumbar spine showed regions of focal fatty replacement and/or hemangiomas within the lumbar spine and chronic wedge deformities. Should I worry?

MRI of lumbar spine showed regions of focal fatty replacement and/or hemangiomas within the lumbar spine and chronic wedge deformities. Should I worry?

Not too much: The area of fatty replacements and/or hemangiomas within the lumbar spine are not significant, and pose no future problem for you. However, the chronic wedge deformities may be due to prior trauma with injury to the vertebral bodies, or possible osteopenic compression fractures. Discuss with you doctor about possibly osteoporosis or other bone abnormality, and how to limit further injury. ...Read more

What is the different between one series of Spine MRI pictures to Cervical, Thoracic, or lumbosacral Spine Mri (each separate)?

What is the different between one series of  Spine MRI pictures to Cervical, Thoracic, or lumbosacral Spine Mri (each separate)?

Being able to: optimize MRI technical parameters to specific regions of the spine allows for a more detailed examination than when attempting to image the entire spine in a single field of view. ...Read more

My dad had a nuclear bone scan. Nuclear bone scan findings: there are several focal areas of isotope accumulation in the region of the sacroiliac joints bilaterally which correspond to lesions noted on the CT pelvis consistent with bony me

My dad had a nuclear bone scan. Nuclear bone scan findings: 
       there are several focal areas of isotope accumulation in the region of the 
       sacroiliac joints bilaterally which correspond to lesions noted on the CT pelvis consistent with bony me

Possibly metastases: Nuclear bone scans usually demonstrate areas of increased bone metabolism, the bone reacting to a stimulus, such as tumor, fracture, infection, etc.Bone scan is very sensitive but not specific. Ct and MRI are cross sectional imaging that can more specifically identify the pathology and characterize the abnormalities on bone scan. ...Read more

Does an MRI of the spine show spinal fluid problems?

Does an MRI of the spine show spinal fluid problems?

Need a spinal tap: For evaluating spinal fluid a spinal tap is necessary. This is the only way to evaluate the fluid for any problems. An MRI would only be able to evaluate if there is a leak in the sac containing the nerves. ...Read more

What is the major benefit of fusion imaging with PET and CT scans?

What is the major benefit of fusion imaging with PET and CT scans?

It combines: the high sensitivity of PET with the high level of anatomic detail of CT, so an abnormality on PET can be accurately localized. ...Read more

Can CT scan and MRI of pelvis and abdomen also gather images of the interior colon?

Can CT scan and MRI of pelvis and abdomen also gather images of the interior colon?

CT Colongraphy: A special ct with bowel cleansing and gentle inflation of the colon can provide an excellent view of the inside of the colon. This specific protocol is called ct colonography, and not every imaging center or hospital can perform it well. Ask about special reviewing software, and how many ct colonographies performed per week. ...Read more

A slight loss of anterior stature of the L1 vertebra is unchanged, compared to the CT scanogram of 2009. Other lumbar vertebrae are normal in stature. There is no lumbar spondylolisthesis. Axial images suggest a nondisplaced fracture of the L4 facet (imag

Need more info: Not sure what your question is, but how old are you and what are your symptoms? Have you had any trauma lately? All these factors help determine the significance of any radiographic abnormality. Also, when the radiologists use a term like "suggest", it means they can't tell for sure if an abnormality is really present or not. ...Read more

Bone scan showed increased vascularity in pelvis. Could this be arthritis in my lumbar spine?

Are you: referring to the vascular phase of a 3 phase bone scan? Lumbar spine pathology would localize to the lumbar spine on the bone scan, not the pelvis. ...Read more

Does CT scan of the brain also include looking for scull fractures?

Does CT scan of the brain also include looking for scull fractures?

See answer: Yes - bony fractures, calcifications, blood, some parenchymal abnormalities and possibly infarcts are the main things noncontrast enhanced ct identifies - MRI of the brain is a more sensitive modality to characterize lesions. ...Read more

What does 'diffuse severe attenuation of the left vertebral artery" mean on a neck ct scan with contrast?

What does 'diffuse severe attenuation of the left vertebral artery" mean on a neck ct scan with contrast?

Risk of stroke: Depending on age and other risks, this could be caused by arteriosclerosis (hardening of the arteries), certain autoimmune diseases associated with arterial inflammation (arteritis), certain infections (e.g. syphilis), and other conditions. Whatever the cause, the person with this finding may be at high risk for stroke. Discuss with your doctor without delay. ...Read more

What's the difference between the CT head the MRI brain scan?

What's the difference between the CT head the MRI brain scan?

CT vs MRI: Ct's and mris can focus on different things. Ct is typically used to view bone and look for bleeding while mris are used to view tissues. Also, cts use radiation similar to xrays while and MRI does not expose the patient to any radiation. However, anyone with a magnetic metal in their body can not get an mri, since MRI uses a large magnet. ...Read more
