Heterogeneity: Causes & Reasons

Possible Causes for Heterogeneity

It is suggested that the Russell-Silver syndrome is heterogeneous and that the criteria for its diagnosis need re-evaluation. [ncbi.nlm.nih.gov]

Clinical presentation is heterogeneous in RSS patients with 11p15 ICR1 hypomethylation. [ncbi.nlm.nih.gov]

The case is another illustration of the genetic heterogeneity of Russell-Silver phenotype. [ncbi.nlm.nih.gov]

Common Cold

The very high heterogeneity means that the averaged estimates must be viewed with caution. [ncbi.nlm.nih.gov]

Heterogeneity was evaluated using the I 2 statistic. When substantial heterogeneity was found ( I 2 ≥ 40%), subgroup analyses were performed. [dx.doi.org]

In addition, we aimed to identify potential sources of heterogeneity in results obtained and to assess their clinical significance. [ncbi.nlm.nih.gov]

Hibernoma

MRI revealed that the lesion was heterogeneously hyperintense on T1W (lower in intensity than subcutaneous fat) and heterogeneously hypointense on fat-saturated T2W and STIR [mdanderson.elsevierpure.com]

On T1-weighted imaging, it was heterogenous and hypointense to surrounding subcutaneous fat. [ncbi.nlm.nih.gov]

It showed mild heterogeneous enhancement on the post-contrast fat-saturated T1 MR images due to increased vascularity. A biopsy of the lesion was performed. [mdanderson.elsevierpure.com]
