Radiologists display powerful new tools

Article Abstract:

Presentations given at the 80th Scientific Assembly and Annual Meeting of the Radiological Society of North America in 1995 unveiled promising applications of radiologic technology that may aid medical research, diagnosis, and patient care. The National Library of Medicine's Visible Man is a compilation of thousands of radiographic and photographic images of the human body. The images were digitized and can be downloaded from the Internet. Virtual reality applications use patients' radiologic images to create three-dimensional anatomical models. The reproductions can be used to help physicians diagnose lung or colon cancer. Patients with brain tumors may be spared surgery in favor of a new treatment that uses radio waves guided by magnetic resonance imaging (MRI). A new ultrafast MRI technique that uses an echoplaner device can scan the entire human body in 18 to 40 seconds. This technique may increase the quality of MRI images and improve patient comfort.

Images gleaned at radiologists' annual meeting

Article Abstract:

Some of the issues discussed at the 1995 annual meeting of the Radiological Society of North America included a variation of skier's thumb, domestic violence, appendectomy without surgery and secure data transmissions. Researchers have developed a variation of a software program called PGP to encrypt medical images that will be transmitted over high-speed networks. Magnetic resonance imaging of the thumb can identify skiers who need surgery for Stener lesion, a variation of skier's thumb in which the ligaments in the thumb are torn. A physician described a procedure that uses an endoscope guided by fluoroscopy to remove a tumor or diseased appendix without surgery. Emergency room physicians should consult with a radiologist when confronted by a patient who may have been abused. Detailed X-ray images can detect the signs of abuse.

Radiologists learn results of new therapy trials, hear latest speculations on cause of old disorder

Article Abstract:

Several new therapies, diagnostic techniques and discoveries were announced at the 82nd Scientific Assembly and Annual Meeting of the Radiological Society of North America. The therapies included using embolus therapy where a gelatin sponge is placed on the bleeding site to prevent uterine hemorrhages and a sterilization technique where metal coils are put in the fallopian tubes without surgery. Computed tomography (CT) advances help diagnosis of appendicitis and determining the infectious agents causing pneumonia. The 19th century Elephant Man was also diagnosed with Proteus syndrome instead of neurofibromatosis based on CT of his skeleton.
