Primary Peritoneal MesotheliomaA 56-year-old Vietnam veteran man was admitted with a three-day history of worsening abdominal pain progressing into an acute abdomen. He had past medical history of Hepatitis C, diabetes mellitus, high blood pressure and chronic abdominal pain of unknown etiology. There was no gross bowel pathology by upper endoscopy or colonoscopy early the year of admission.

Tomographic tactic conquers planar imaging limitationsImaging in medicine dates its origin to 1895, when Roentgen discovered the x-ray. This exciting and novel technology opened an unprecedented era in medicine, which continued through the 20th century and remains a major element of the day-to-day practice of radiology. Limited, modest efforts made during the mid-20th century to employ tomographic methodologies eventually led to the introduction of x-ray CT by Sir Godfrey Hounsfield in 1973.

Ultrasound leads conservative treatment of calvarial dermoidsCalvarial dermoids and epidermoids in young pediatric patients can be monitored using ultrasound alone instead of x-ray based imaging, according to German researchers. Besides being safer and cheaper, sonography could rule out unnecessary surgeries.

FDG-PET imaging tackles large arteries with atherosclerosisA noninvasive technique to detect vulnerable atherosclerotic plaque is critically needed. Formation of atherosclerotic plaque is a dynamic inflammatory process that involves interactions between atherogenic lipoproteins and macrophages. As vulnerable plaques are usually numerous, extending beyond the culprit plaque and involving multiple vessels, targeting a single plaque underestimates the complexity and extent of disease. Thus, an ideal imaging modality should be able to identify the vulnerable arterial bed and, therefore, the vulnerable patient, to prevent the serious complications of atherosclerosis.

Three-D postprocessing shines in abdomen, pelvisMoviegoers may relegate those red- and green-lensed cardboard glasses worn while watching 3D movies to a bygone era. But the release of a spate of animated movies in true digital 3D format over the past several years proclaims the comeback of this exciting genre. In an unlikely comparison, 3D diagnostic imaging, buoyed by recent technological advances, is also beginning to hit its stride and could herald a new imaging paradigm in multislice CT.

Faster temporal resolution takes on all heart ratesCoronary CT angiography is one of the most promising new applications of CT technology. Despite the increasing number of detectors in CT scanners, however, coronary CT imaging had not solved the key issue: dealing with a structure that is in almost constant motion. That is, until the advent of dual source CT.
