2024年8月30日 · Bone marrow signal of the clivus changes predictably with age and is well assessed with midline non-contrast T1WI without fat saturation. As is seen in the rest of the body the proportion of yellow (fatty) marrow increases with age.

2024年5月9日 · The clivus (of Blumenbach) is the sloping midline surface of the skull base anterior to the foramen magnum and posterior to the dorsum sellae 1. Specifically, the clivus is formed by the sphenoid body and the basiocciput, which …

Typical MRI findings ( Fig. 6—I, II) include hypointense signal on T1W and hyperintense signal in the clivus on T2W images with enhancement on post-contrast imaging. However, fungal infections appear classically hypointense on T2W images.

The clivus is a bone region between dorsum cella and foramen magnum. It can be evaluated very clearly in routine brain magnetic resonance imaging (MRI) dueto its central location. Quantitative and qualitative evaluation of the clivus and its changes ...

2013年1月19日 · MR images of 21 patients with an abnormal clivus (19 with tumor invasion and two with marrow reconversion) were also evaluated retrospectively and compared with those of the control group to assess MR features distinguishing the two groups.

2013年11月23日 · Sagittal T1 MRI image shows a smooth, ovoid mass centred in the clivus. A further deposit of similar low T1 signal intensity lesion is also noted within the body of C2 vertebra. This patient had myeloma.

The clivus (Latin for "slope") is a part of the cranium, a shallow depression behind the dorsum sellæ that slopes obliquely backward. It forms a gradual sloping process at the anterior most portion of the basilar occipital bone at its junction with the sphenoid bone.

1990年9月1日 · We retrospectively reviewed 330 T1-weighted sagittal images, 80 T2-weighted sagittal images, and 83 gadopentetate-dimeglumine-enhanced scans of normal adults to determine the MR appearance of the normal adult clivus.

We retrospectively reviewed 330 T1-weighted sagittal images, 80 T2-weighted sagittal images, and 83 gadopentetate-dimeglumine-enhanced scans of normal adults to determine the MR appearance of the normal adult clivus.

tomography (CT) and magnetic resonance imaging (MRI) are helpful to differentiate between non-tumoral and tumoral conditions and in searching for malignant characteristics.
