Which of the following imaging types is most useful for detecting lesions that may be missed on T1 scans?

The most useful imaging type for detecting lesions that may be missed on T1 scans is T2 weighted MRI. T2 weighted MRI sequences are particularly adept at highlighting areas of increased water content, which is often indicative of edema and inflammation commonly seen in Multiple Sclerosis. T2 scans are sensitive to changes in tissue composition and can reveal lesions that might not be visible on T1 scans due to their low sensitivity to certain types of lesions.

Leison visualization in MS patients is crucial, and T2 weighted MRI does a superior job in displaying demyelinating lesions, particularly those that are more acute or those that have high water content. This increased sensitivity makes T2 weighted MRI the preferred choice when it comes to identifying lesions that may be undetected on T1 sequences, where lesions that have undergone certain changes may appear as isointense or hypointense compared to surrounding brain tissue.

While other imaging modalities have their own uses, they do not provide the same level of detail or specificity for detecting the lesions characteristic of Multiple Sclerosis. CT scans are less sensitive to subtle changes in the brain's white matter. FLAIR imaging, while also useful for visualizing lesions, can sometimes be seen as a more specific variant of T2 MRI, but it
