Relationship between MRI findings and invasive breast cancer with podoplanin-positive cancer-associated fibroblasts.

Objective: Purpose of our study is to assess the relationship between MRI findings and invasive breast cancer (IBC) with cancer-associated fibroblasts (CAFs) that are positive for podoplanin.

Methods: We retrospectively analyzed the consecutive 109 IBCs. The IBCs were dichotomized as with (+) or without (-) podoplanin-positive CAFs.

Tumor-stromal ratio (TSR) of invasive breast cancer: correlation with multi-parametric breast MRI findings.

Objective: To correlate the tumor-stromal ratio (TSR) of invasive breast cancer and MRI findings.

Methods: This study was approved by our institutional review board. 126 consecutive patients with surgically proven invasive breast cancer were included.

Arterial spin-labeling MR imaging of cerebral hemorrhages.

Introduction: The purpose of this study is to identify the characteristics of brain perfusion measured by arterial spin-labeling magnetic resonance imaging (ASL-MRI) in cerebral hemorrhages.

Methods: Brain blood flow values (CBF-ASL values) for cerebral and cerebellar hemispheres and segmented cerebral regions were measured by ASL-MRI in 19 putaminal hemorrhage patients and 20 thalamic hemorrhage patients in acute or subacute stages. We assessed the lateralities of CBF-ASL values and the relationships between CBF-ASL values and other imaging findings and clinical manifestations.

CT-gastrography for early gastric cancer visualized by wall-carving technique using contrast-enhanced MDCT for portal phase.

Objective: The wall-carving (WC) imaging technique is used to evaluate early gastric cancer using multidetector row computed tomography (MDCT) image data for only the arterial phase. Our purpose was to investigate if WC images derived from portal phase MDCT images can enhance the visualization of early gastric cancer.

Subjects And Methods: Fourteen consecutive patients (average age/age range (years) = 75.
