BACKGROUND AND PURPOSE:The histogram method has been shown to demonstrate heterogeneous morphologic features of tumor vascularity. This study aimed to determine whether whole-tumor histogram analysis of the normalized CBV for contrast-enhancing lesions and perienhancing lesions can differentiate among GBMs, SMTs, and lymphomas.

In cases of sharp or pointed foreign body ingestion, if the result of an initial inspection of oro- and hypopharynx reveals negative findings, the first imaging modality should be MDCT for better diagnosis and management.
