Subarachnoid space disease: diagnosis with fluid-attenuated inversion-recovery MR imaging and comparison with gadolinium-enhanced spin-echo MR imaging--blinded reader study.

abstract：:The difficulty of demonstrating lesions near the chest wall is one source of error in mammography. A mediolateral xeroradiograph of the breast which images the chest wall was added to the routine mediolateral and cephalocaudal film-screen projections to minimize this problem. In one case, a posterior breast lesion was...
