Not too long ago, the capability of precisely directing and guiding a potent beam of radiation to eradicate a cancerous tumor without harming the healthy tissue around it was a pipe dream. Fodder for the imagination and science fiction.

One of the most prominent figures in nuclear medicine in the last half-century is Dr. Henry Wagner of Johns Hopkins University in Baltimore, MD. Dr. Wagner has conducted pioneering research in imaging the perfusion and ventilation of the lungs, kidney and spleen scanning, myocardial perfusion scanning with potassium-43, gated blood pool imaging and imaging brain receptors with PET.

Digital imaging is now ubiquitous in medicine. Contemporary imaging modalities are generating an ever-increasing amount of data, and a growing number of healthcare professionals require access to this data. However, this exponential increase in the generation and usage of digital imaging poses new data management problems for the administrators of picture archiving and communication systems (PACS). In response, emerging storage grid technologies offer a practical means to addressing many of these problems.
Explosion of Imaging Data

A 30-year-old woman arrives in the emergency room with “abdominal cramping and vaginal bleeding. A physical examination reveals a palpable left adnexal mass. She has a positive pregnancy test with beta-HCG of 14,000 IU/L. The emergency department (ED) physician considers magnetic resonance imaging (MRI) of the pelvis, yet it is expensive and not the initial study of choice.

Anyone who remembers – or for that matter, still uses – single-slice CT scanners can appreciate the dramatic advancements made by leading CT system manufacturers in recent years. The latest CT, Multidetector CT (MDCT), and MRI systems are faster and feature higher resolution than ever before.


For most of us, handheld devices put the “fun” in functional. In the medical world, these tools do much more — they help save lives.

Acquiring used equipment carries with it certain stereotypes that span the spectrum of good to bad. Facilities that acquire used equipment either are considered economically savvy or they’re simply picking up a poorly serviced clunker to help them deliver basic service with no ambitions or goals of being a high-end provider.

Chest pain is a common complaint among ED patients, yet failure to diagnose acute myocardial infarction in the trauma unit occurs in as many as 20 percent of cases, according to some estimates.
Serious conditions that are occasionally misdiagnosed in the ED include: acute myocardial infarction, stroke, pulmonary embolism, meningitis and appendicitis. Standard protocol for chest pain is an echocardiogram (ECG); however, physicians may rely too heavily on this test, which does not rule out a heart attack if results are normal.

The Harmony V Keyless Entry (push-button) cart features a programmable automatic re-lock and a manual key override. The cart is available in four standard color options: white, red, blue and yellow. Optional accessories include: plastic trays and dividers; sharps container; suction pump holder; upper rack with tilt-out bins; monitor/defib shelf; IV pole; scope holder; and more.

Along with the already established S2 20-inch surgery light, the new S1 surgery “satellite” and the new P1 video camera system have just been introduced. The S1 complements the larger S2 light, as a smaller, more compact surgery head which includes all of the features found in the S2. The new P1 video camera dramatically increases the capabilities for the surgery room, regarding monitoring or recording surgeries. The P1 features a 27x optical zoom and autofocus, as well as manual focus.
