What are the MRI findings in MS?

Classically, the MRI shows lesions in the white matter deep in the brain near the fluid spaces of the brain (the ventricles). The test may also show changes in the cortex or near the cortex. MRI can also show changes in the brainstem and in the spinal cord.

What would an MRI show for a ACL tear?

Imaging specialists may use an MRI to see swelling and to look for fiber discontinuity. They may also look at the angle of your ACL compared to the optimal angle of this ligament to see how it’s shifted. By examining the direction of the ligaments apex, they can usually assess the severity of the tear.

Can ACL tear be misdiagnosed on MRI?

ACL tears are also often misdiagnosed as collateral ligament knee strains. With that being said, when a trained musculoskeletal radiologist is reading the case, an ACL tear or other abnormality is rarely missed. This is why a radiologist with subspecialty training is recommended to look at your MRI.

How accurate is MRI in detecting ACL tear?

The sensitivity, specificity, and accuracy of MRI in the diagnosis of ACL injury were 95.45% (63/66), 91.67%, and 94.87%, respectively. The accuracy of MRI in the diagnosis of complete and partial tears were 92.86% and 94.74%, respectively.

Where are lesions most common in MS?

Lesions may be observed anywhere in the CNS white matter, including the supratentorium, infratentorium, and spinal cord; however, more typical locations for MS lesions include the periventricular white matter, brainstem, cerebellum, and spinal cord.

Where do MS lesions appear?

MS can cause a wide variety of neurologic symptoms since it can affect numerous areas of the brain, optic nerve, and spinal cord (Figure 3). Characteristic lesions are located in the periventricular and juxtacortical regions, in addition to the brainstem, cerebellum, spinal cord, and optic nerve.

What can a knee MRI miss?

MRI has been quoted in the literature as being only about 76% accurate for medial meniscal tears, 75% accurate for lateral meniscal tears1 and about 86% accurate for diagnosing ACL tears2. Therefore, for even the most common knee injuries MRI can miss up to ΒΌ of all potential actual pathologies!

What is the gold standard for ACL tear?

The gold standard in ACL injury evaluation is diagnostic arthroscopy3,4; however, the diagnostic accuracy of clinical diagnostic tests and magnetic resonance imaging (MRI) is debatable. Because of the frequency of knee injury,3 MRI is a common diagnostic tool used for imaging and diagnosis.
