Ruptured pancreaticoduodenal arterial aneurysms: diagnosis and treatment by angiographic intervention.

This article describes a 54-year-old patient who presented with a long history of epigastric pain. Laboratory values revealed a decreased red blood cell count, decreased hemoglobin level, and positive stool hemoccult test. A computed tomography scan of the abdomen revealed intra-abdominal and retroperitoneal hematomas.

Serial nonenhancing magnetic resonance imaging scans of high grade glioblastoma multiforme.

Magnetic resonance imaging (MRI) from clinical experience has proven to be superior to all other diagnostic imaging modalities, including computed tomography (CT) in the detection of intracranial neoplasms. Although glioblastoma multiforme presents a challenge for all diagnostic imaging modalities including MRI, MRI is paramount to CT in detecting subtle abnormal water accumulation in brain tissue caused by tumor even before there is disruption of the blood brain barrier. Currently, clinical research and investigational trials on nonionic gadolinium contrast agents have proven that nonionic gadolinium HP-DO3A (ProHance) contrast agents have lower osmolality and greater stability, which make them superior compounds to gadolinium diethylenetriamine-pentacetic acid (Gd-DTPA).

AIDS: the role of imaging modalities and infection control policies.

The availability of imaging modalities, such as the chest radiograph, gallium scan, double-contrast barium enema, computed tomography, and nuclear magnetic resonance, are very helpful in the diagnosis, treatment, and follow-up evaluation of patients with acquired immunodeficiency syndrome (AIDS). Because this syndrome causes irreversible destruction of the immune system, patients are susceptible to a multitude of opportunistic infections and malignancies. Health care professionals and the general public would be less fearful and apprehensive of AIDS victims if properly informed about the communicability of this syndrome.
