MR Imaging of Primary Bone Tumors and Tumor-like Conditions in Children.
This article provides a review of the MR imaging features of the major primary malignant and benign bone tumors and tumorlike conditions encountered in the pediatric population. Malignant tumors discussed include osteosarcoma, Ewing sarcoma, chondrosarcoma, lymphoma, and malignant fi...
Ultrasound in musculoskeletal tumors with emphasis on its role in tumor follow-up.
Ultrasonography allows visualization of musculoskeletal masses that are not confined to the intraosseous compartment and assists in the determination of the consistency of such masses. Making a specific diagnosis using ultrasonography is hampered by the lack of specificity; however, it may be an ind...
Primary tumors of the optic nerve are uncommon. The most common are optic nerve gliomas (ONGs), which account for 66% of all primary optic nerve tumors. Seventy-five percent of gliomas are diagnosed in the first decade of life, and 90% are diagnosed in the first two decades. This article discusses t...
Pelvic tumors in childhood.
Pelvic neoplasms can arise from the genitourinary tract, gonads, or soft tissues. When a pelvic mass is detected on physical examination or a conventional radiographic study imaging evaluation is performed to characterize the lesion further and determine its site of origin and extent. Ultrasonograph...
Valvular heart disease.
This article reviews existing magnetic resonance imaging techniques used to evaluate valvular heart disease. Specifically, this article discusses the capabilities of magnetic resonance imaging for (1) the detection and quantification of valvular regurgitation; (2) the detection and quantification of...
Evaluation of ischemic heart disease by magnetic resonance imaging and spectroscopy.
Important aspects of ischemic heart disease are currently evaluated with magnetic resonance imaging and phosphorus-31 spectroscopy. The combined use of magnetic resonance imaging and spectroscopy will enable the noninvasive visualization of the coronary arteries, provide flow velocity and volume dat...
Angiocardiography in the diagnosis of congenital heart disease.
Despite tremendous advances in cardiac imaging technology, there still exists an important role for the performance of angiocardiography in children with congenital heart disease. This article contains an outline describing the facilities in which the examinations are performed, how the examination...
Clinical syndromes and differential diagnosis of spinal disorders.
In this article an overview of the different clinical aspects of spinal syndromes is presented. The common disorders involving the spinal cord, the spine, and the intervertebral disc are emphasized.
The fetal genitourinary tract.
Early recognition of fetal urinary tract anomalies may dramatically influence obstetric or neonatal management. Major fetal urinary abnormalities, including renal agenesis, obstructive lesions, and cystic disease, may be clinically silent but readily identified by sonography. Careful...
Fetal gastrointestinal abnormalities.
A wide range of abnormalities of the fetal gastrointestinal tract is currently detectable by antenatal sonography, but the sonographic appearance of normal fetal bowel is variable, with considerable overlap between normal and abnormal patterns. In examining the major gastrointestinal disorders that...
