This study aimed to evaluate magnetic resonance (MR) imaging appearances of 11 gastrointestinal stromal tumors in the abdomen and pelvis and compared them with some histological findings. Gastrointestinal stromal tumor showed nonhomogeneous signal intensity and included hemorrhage in large tumors. Gastrointestinal stromal tumors showed a wide variety of(More)
Primary small cell carcinoma of the breast is a rare breast cancer. We report two cases of this entity showing a non-mass-like pattern on multimodality images and histopathology. Both women presented with a breast mass, and one had axillary lymphadenopathy. Both cases revealed fine calcification on mammography (MMG) and an irregularly shaped, hypoechoic(More)
PURPOSE To assess the feasibility of contrast-enhanced fat-saturated three-dimensional steady-state free precession (FIESTA) imaging for contrast-enhanced magnetic resonance (MR) portography. MATERIALS AND METHODS Contrast-enhanced fat-saturated three-dimensional fast spoiled gradient-echo (SPGR) and FIESTA were performed as MR portography. In 10 cases,(More)
OBJECTIVE The objective of our study was to use MRI to show the cardiac morphology and function of patients with hypertrophic obstructive cardiomyopathy after percutaneous transluminal septal myocardial ablation. CONCLUSION Black blood T2-weighted and contrast-enhanced fast inversion recovery gradient-echo images displayed ablated septal myocardium until(More)
BACKGROUND/AIMS To accurately quantify liver function using gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid (Gd-EOB-DTPA)-enhanced MR imaging. METHODOLOGY A total of 105 patients with suspicion of a hepatic tumor (Child–Pugh scores: 5 in 56, 6 in 26, 7 in 20, and 8 in 3) who underwent Gd-EOB-DTPA-enhanced MR imaging and an indocyanine green(More)
The collapsed maxillary alveolar arch in bilateral cleft lip and palate (BCLP) patients was quantitatively evaluated by three dimensional analysis. Materials were consisted of alveolar models taken from 15 Japanese boys (11 years old) with BCLP. The findings obtained were as follows: 1. Examination of the alveolar displacement in individual BCLP patients(More)
PURPOSE The purpose of this study was to determine texture parameters reflecting the background parenchymal enhancement (BPE) of the breast, which were acquired using texture analysis (TA). METHODS We investigated 52 breasts of the 26 subjects who underwent dynamic contrast-enhanced MRI. One experienced reader scored BPE visually (i.e., minimal, mild,(More)
An 82-year-old Japanese man was referred for detailed examination of hyperkeratotic erythematous plaques on his palms and soles for 6 months. Two weeks before his first visit, he had undergone lung lobectomy for right lung squamous cell carcinoma (SCC). Laboratory findings showed elevations of eosinophil counts, serum IgE, thymus and activation-regulated(More)
