Angioleiomyoma represents a benign stromal tumor, which usually occurs in the subcutaneous tissue of the extremities. The angioleiomyoma in the finger is rare. We report 2 rare cases of an angioleiomyoma in finger. Case one, was a 72-year-old man with a mass on the radial side of distal phalanx of the left third finger. Case two, was a 70-year-old man with a mass on the ulnar side of interphala...

Objective: The aim of this study was to compare the quality of images obtained with 3D T2-weighted sequence with the quality of conventional 2D T2-weighted images. Subjects and Methods: Thirty consecutively registered patients (average age, 55 year; age range 32-79 years) underwent imaging at 3.0 T with a 6-element body array coil. All imaging was performed with three T2-weighted images: 3D axi...

Magnetic Resonance (MR) Image-guided prostate biopsy in a 0.5-T open scanner is described, validated in phantom studies, and employed in two patients. The needles are guided by fast gradient recall and T2-weighted fast spin echo images. Surgical navigation software provided T2-weighted images that were critical in targeting the peripheral zone and the tumor. MR imaging can be used to guide pros...

BACKGROUND MR-guided focused ultrasound (MRgFUS) might be a very safe and effective minimally invasive technique to treat facet joint pain caused by arthritis and other degenerative changes. However, there are still safety concerns for this treatment and challenges regarding MR imaging and temperature mapping due to susceptibility effects between the bone and soft tissue near the joint, which h...

Introduction High-resolution 3D imaging is useful for improving the specificity of breast MRI since morphological characteristics, such as spiculations and heterogeneity, vary with histology [1]. The specificity of breast MRI can be further improved by considering physiological information such as diffusion [2]. Unlike T1-weighted contrast-enhanced imaging, it is difficult to acquire high-resol...

Automatic detection of brain tumor is a difficult task due to variations in type, size, location and shape of tumor. A multi-modality framework for automatic tumor detection by fusing different Magnetic Resonance Imaging modalities including T1-weighted, T2-weighted, and T1 with gadolinium contrast agent. The intensity, shape deformation were extracted from each image. The Multimodal MR images ...

PURPOSE To retrospectively determine the accuracy of diffusion-weighted (DW) magnetic resonance (MR) imaging for identifying cancer in the prostate peripheral zone (PZ) and to assess the accuracy of tumor volume measurements made with T2-weighted imaging and combined T2-weighted and DW MR imaging by using surgical pathologic examination as the reference standard. MATERIALS AND METHODS The ins...
