Lymphatic pathway around the pancreatic head and extrahepatic bile duct: evaluation using MR imaging at 3.0-T.

Purpose: To evaluate the utility of spectral presaturation with inversion recovery (SPIR) T2-weighted images with 3-dimensional (3D) volume isotropic turbo spin echo acquisition (VISTA) at 3.0-T for the detection of the normal lymphatic systems located around the pancreatic head and extrahepatic bile duct.

Materials And Methods: Fifty-six patients with suspected hepatic or pancreaticobiliary diseases and diagnosed as normal or benign pathologies were evaluated as having normal lymphatic systems.

"Peripancreatic strands appearance" in pancreatic body and tail carcinoma: evaluation by multi-detector CT with pathological correlation.

Objectives: In pancreatic body and tail carcinoma, "peripancreatic strands appearance" is frequently seen on multidetector CT (MDCT). The purpose of this study was to clarify the pathological and clinical implications of peripancreatic strands appearance.

Methods: We retrospectively evaluated MDCT images in 17 patients with pancreatic body and tail carcinoma who underwent surgical resection.

Salivary duct carcinoma of the extra-glandular segment of Stensen's duct: radiological findings and pathological correlation (2008: 10b).

Salivary duct carcinoma (SDC) of the extra-glandular segment of Stensen's duct is a very rare but aggressive neoplasm. Ultrasonography, computed tomography, and magnetic resonance imaging findings in a patient pathologically proven to have SDC of the extra-glandular segment of Stensen's duct are reported. When an early peak enhancement region in the mass with a well-enhanced dilated and thickened Stensen's duct wall is apparent on dynamic studies, a SDC of the extra-glandular segment of Stensen's duct should be strongly suspected.

Peripancreatic lymphatic invasion by pancreatic carcinoma: evaluation with multi-detector row CT.

Peripancreatic lymphatic networks are frequently involved in pancreatobiliary carcinoma, affecting the prognosis. However, little attention has been paid to CT imaging of normal and pathological conditions of peripancreatic lymphatic networks. We evaluated multi-detector row CT (MDCT) images of peripancreatic lymphatic networks invaded by pancreatic carcinoma and compared them with those of normal peripancreatic lymphatic networks using imaging reconstruction every 1 mm with a multiplanar reformation technique.
