Jan 19, 2013 · 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.

In brain MRI, by proportioning intensity values (signal intensity ratios of clivus/pons and clivus/CSF) measured from equal size areas at T1-weighted sequence at midsagittal sections, normal ranges have been determined for clivus intensity values according to …

Aug 30, 2024 · 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.

Sep 22, 2020 · An important normal variant that can sometimes be mistaken for clival pathology is a prominent basilar venous plexus that can appear to erode the posterior surface of the clivus 4, as well as prominent clival diploic veins that may mimic masses of the body of the clivus 5.

Jan 19, 2013 · Primary neoplasms, metastatic tumors, and inflammatory, vascular, and hematopoietic disorders are the most common abnormalities to arise from or directly involve the clivus. MR imaging exquisitely shows and helps characterize the diseases that affect this area.

Sep 1, 1990 · 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.

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.

May 9, 2024 · MRI. On T1-weighted images, the signal intensity of clivus varies with age. In childhood, red haematopoetic bone marrow contributes to low signal intensity on T1-weighted images. As the child ages, the signal intensity of clivus becomes heterogenous with increasing infiltration of fatty marrow and subsequently become hyperintense in old age 5.

Background: 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. Objectives: Quantitative and qualitative evaluation of the clivus and its changes according to age in a group of healthy people.
