An exhibit of the types of head trauma one may see during an evening shift in a busy emergency room. This exhibit won the Cum Laude Award for scientific exhibits at the 2001 meeting of the American Society of Neuroradiology, in Boston, MA.
This computer-based exhibit outlines the MRI protocols we use to evaluate the breast for malignancy and to evaluate breast implant integrity. The MR appearance of various breast disease states, with pathologic correlation is reviewed. Special emphasis is placed on the dynamic enhancement characteristics of benign and malignant breast disease. Attention to both morphology and enhancement of breast lesions, in the setting of the associated mammographic and ultrasound findings, can improve the accuracy of breast MRI interpretation.
This computer exhibit reviews the typical characteristics of benign and malignant breast disease on MRI and contrasts this with cases having unusual imaging findings. Mammographic, ultrasound and pathologic correlation is included. Evaluation of breast lesions with MRI must be performed in the context of the mammographic, ultrasound and physical exam findings.
External to Internal Carotid Artery Anastomotic Connections: Potential for Danger in Neurologic Interventional Procedures
With the ever-increasing field of intracranial neurologic interventions, the knowledge of potentially dangerous collateral pathways is essential for decreasing the risk of iatrogenic hemorrhage and infarction and is critical for planning neurologic interventional procedures. This web-based program is used to illustrate anastomotic connections between the internal and external carotid circulations, display examples of intracranial circulatory normal variants and describe angiographic techniques which improve visualization of these anastomoses.
First, pick a tendon and a scanning plane. Then, move your mouse over the scanning planes shown on the patient's shoulder to see a sonographic slice through that tendon in that location. To see labeled anatomy on a given slice, click your mouse button.
Tibial plateau fractures represent a complex injury to the knee. At our institution, these fractures are classified by radiologists and orthopedic surgeons using the Schatzker classification system. This system sorts these fractures into groups with similar mechanisms and patterns, and aids in treatment planning.
Hallux valgus is a common foot disorder of several etiologies, which can lead to significant foot pain and deformity. This online exhibit covers some of the typical pre- and postoperative radiographic findings of this very common and very treatable cause of foot pain.
