Imaging studies of intraductal tubulopapillary neoplasms of the pancreas: 2-tone duct sign and cork-of-wine-bottle sign as indicators of intraductal tumor growth.
The objective of this study was to describe the imaging findings for intraductal tubulopapillary neoplasms of the pancreas. ⋯ Intraductal tubulopapillary neoplasms are rare tumors showing characteristic imaging findings such as the 2-tone duct sign and the cork-of-wine-bottle sign that represent their intraductal growth.

Diffusion tensor magnetic resonance imaging of rat glioma models: a correlation study of MR imaging and histology.
Diffusion tensor magnetic resonance (MR) imaging (DTI) can be used to characterize the microstructures of ordered biological tissues. This study was designed to assess histological features of gliomas and surrounding brain tissues in rats using DTI. ⋯ Quantitative analysis of DTI indices provides useful information for assessing tumor microstructure and tumor cell invasion into the adjacent gray matter and white matter.
