WebBone determinations due to malignant hemopathies (MH) were in general hypointense on T1-weighted sequences, iso- or hyperintense on T2-weighted sequences. On the other hand, bone metastases were hypo- or isointense on T1-weighted sequences, and had no specific signal intensity on T2-weighted sequences. WebT1 -hypointense lesions (T1-black holes) in multiple sclerosis (MS) are areas of relatively severe central nervous system (CNS) damage compared with the more non-specific T2-hyperintense lesions, which show greater signal intensity than normal brain on T2-weighted magnetic resonance imaging (MRI).

WebPituitary microadenomas are easier to identify on T1-weighted sequences than on T2-weighted sequences because they are often isointense to normal pituitary tissue on the latter. On T1-weighted sequences, microadenomas tend to appear as focal hypointense lesions. Occasionally, they are isointense or even hyperintense to the surrounding pituitary. Webspinal cord and was isointense with it on T1-, proton density–, and T2-weighted images (Fig 2). At surgery, the dimple was resected.

WebClival tumors were found to enhance intensely. A clivus of very low signal intensity (signal void) on T1- or T2-weighted images was always abnormal. The clivus with marrow reconversion was uniformly hypointense relative to the pons on T1-weighted images and isointense relative to normal marrow on T2-weighted images. WebAbnormal marrow is isointense or hypointense to skeletal muscle on T1-weighted imaging because the replacement of fatty marrow elements by the pathologic process causes loss of the normal fat signal (Fig. 1A, 1B, 1C ). Both STIR and T2 fast spin-echo-weighted fat-suppression images are extremely sensitive for detecting fluid.
