Mri Of The Foot Without Contrast
Maybe safer in some: Gadolinium contrast could potentially cause kidney complications on rare occasion. Mri without contrast will reveal areas of atrophy, stroke, bleeding, tumors, hydrocephalus, etc, but will not clearly show certain ms lesions, aneurysms, avm's, some inflammatory problems, so, always discuss with your doctor as to why an ordered MRI might be done in a variety of ways. ...Read moreSee 2 more doctor answers
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
No contrast usually: Contrast is not usually given for an MRI of the knee. Many times, the knee has an effusion, which acts as a natural contrast agent for MRI. In complex situations, such as after surgery or when the patient's symptoms are more sever than expected by the Doctor, then contrast can be used either by venous injection or with an arthrogram. ...Read moreSee 2 more doctor answers
Is MR arthrography of the hip joint a fancy way of saying MRI of the hip with contrast media (Gadalinium)?
Is there a visual difference b/w anterior view of knee on X-ray and posterior view of knee on X-ray? Can the patella block view on the anterior X-ray
YES: There would be some difference in what is magnified more, so the accepted x-ray format is an ap. Everyone does it the same. As in a chest x-ray it is always a pa. This uniform practice means any one reviewing a knee x-ray it is always an ap. As far as the patella blocking any thing, yes it does to some degree but also in a pa. This standard is universal so thre is no deviation worldwide. ...Read more

MRI w/w/out Contrast: MRI uses magnetic fields to form images in the body and term with and without contrast comprises the series of films of the MRI. The study is performed with contrast in event there is need for specific differentiation of tumor from other structures, find smaller lesions, and see dynamic assessment of lesion (how active). ...Read more
Will a CT scan of the lumbar spine post fusion without contrast show pinched nerves or just bone structure and hardware?
Yes: Arteries and veins are both seen on non contrast studies also depends on how study is done ...Read more
Why would a MRI of the back be ordered without, and with contrast? What is the contrast enhancing?
It depends: It depends what they are looking for. It is common to perform a spine MRI without/with contrast. If you had prior back surgery, it will help differentiate post surgical scarring(which enhances) from other processes like disc extrusion. Inflammatory and malignant abnormalities will also generally enhance. Vascular abnormalities will enhance. ...Read more
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
CT brain: One of the most common reasons to order CT brain without contrast is to rule out a cerebral hemorrhage - new blood shows up better, and can be obscured with contrast. Structures and any abnormalities such as lesions can still show up quite well without contrast, especially with newer CT imaging. Hope that helps! ...Read more
Spine or ENT spaces: Mri of the neck could mean a study of the cervical spine, and therefore would show disc herniations, vertebral problems and spinal cord problems. It could also mean a study of the anterior spaces of the neck, in which case it will show any problems with the soft tissues, i.E cancer, infection and congenital anomalies. ...Read more
Some things: CT scan of brain without contrast shows basic anatomy of brain, gray white matter differentiation, ventricles, and physiologic calcifications.Ventricles enlarged/ hydrocephalus, mass effect with displacement of normal structures, some bleeding,abnormal calcifications in tumors or old subdural hematomas, fractures.CT with contrast adds enhancement of certain lesions not seen,hyper/hypo vascular. ...Read more

Can CT scan clearly pin point the location of colon perforation and determine the size of the hole, using color contrast drink?
Sometimes : If the perforation is large enough, and the oral contrast is in that loop of bowel, then yes. A very small hole may not be seen that way, but the ct will show air that has leaked out of the bowel, which can help the surgeons if an open repair is required. ...Read moreSee 1 more doctor answer
Which is the better way to determine the degree of cervical stenosis: MRI or CT scan? Where does a contrast dye fit in either approach?
Pluses and minuses: A ct myleogram gives great bony detail but is invasive, contrast placed in thecal sac MRI will give equivalent information without risk of intrathecal contrast and additional information about the state of spinal cord increased signal intensity within the cord bad sign. ...Read more
