We report a case of benign osteoblastoma of the temporal bone and a review of the literature. Osteoblastoma is a rare bony tumor that usually develops in the long bones or in the vertebral column. To our knowledge, this is the fourth reported case of benign osteoblastoma confined to the temporal bone, and it is the second such reported case to include(More)
Thyroglossal duct cysts (TDCs) are common congenital abnormalities of thyroid development. Carcinoma occurs rarely in patients with TDCs. In a large case series drawn from medical records at a health maintenance organization from 1971 through 1995, 14 cases of carcinoma in a TDC were found. This represents the largest known reported case series to date.(More)
Magnetic resonance (MR) imaging is the preferred imaging modality for evaluating internal derangement of the knee, due to its superior soft tissue contrast resolution, multiplanar imaging capability, and lack of ionizing radiation. The superb image quality facilitates learning of normal imaging anatomy and conceptualizing spatial relationships of anatomic(More)
This article discusses anatomic relationships, anatomic variants, and MRI protocols that pertain to the foot and ankle. MR images with detailed anatomic description form the cornerstone of this article. The superb image quality will facilitate learning normal imaging anatomy, as well as conceptualizing spatial relationships of anatomic structures.
BACKGROUND The failure rate of tendon-bone healing after repair of rotator cuff tears remains high. A variety of biologic- and cell-based therapies aimed at improving rotator cuff healing have been investigated, and stem cell-based techniques have become increasingly more common. However, most studies have focused on the implantation of exogenous cells,(More)
Magnetic resonance (MR) imaging is the modality of choice for evaluating the soft tissues of the thigh and leg because of its superior soft tissue contrast resolution, multiplanar imaging capability, and lack of ionizing radiation. The superb image quality facilitates learning normal imaging anatomy, which ultimately forms the foundation of diagnostic(More)
The light yield from both luminol and fluorescein is studied at a fixed concentration of luminol and by varying the concentration of fluorescein in 3 X 10(-2) M basic solution by direct chemical reaction as well as by aqualuminescence technique. The emission spectra of chemiluminescence and aqualuminescence of the alkaline luminol-fluorescein mixture are(More)
