Heart Attack, or Something Else?
Unless a patient with chest
pain is checked out right
away, it can be difficult to
diagnose a heart condition,
as opposed to less
life-threatening causes such
as heartburn. A new stress

GPS For The Brain
Neurosurgeons' jobs are made
easier by a 3-D CT scan
produced by an advanced
imaging system. It produces
a computerized image of
blood vessels and
surrounding soft tissue,
which can be rotated for

Better Body Images In 3D
With MRI or CT scans,
clinicians have to identify
and extract the anatomy out
of cross-sections views of
the body. Computer
scientists have created a
new interactive tool that

Targeting Cancer in 3D
Radiation therapy requires
visualizing exactly where a
tumor is located, usually
from looking at hundreds of
different X-ray , CT or PET
scan images. A new system
patches together 2D images
into one 3D view of the

Neurologists Use New Brain Scanning Device To Better Control Seizures
Doctors are now using a new kind of brain scan called magnetoencephalography (MEG), which measures brain activity in real time. In some cases, MEG can pinpoint the source of an epileptic seizure much ... > more -
Radiologists Use CT Scan To
Medical physicists used computed tomography to compose a picture of the body within an ancient mummy. The scan provided more detail in both bone and tissue than a conventional x-ray. The three ... > more -
Gastroenterologists Use Hi-Res Narrow-Band Imaging to Find Cancer
Gastroenterologists Use Hi-Res Narrow-Band Imaging To Find Cancer New optical technologies are helping gastroenterologists improve cancer detection using colonoscopy. A new endoscope uses HDTV ... > more -
Radiologists Use Digital Tomosynthesis To Produce 3-d Image Of Breast
Radiologists have devised a better way to perform a mammogram, called digital tomosynthesis. An X-ray tube moves in an arc around the breast, capturing several images. The information is then sent to ... > more -
Doctors Catch Cancer Earlier with Special MRI
A new kind of MRI machine helps doctors diagnose breast cancer earlier. Patients lie on their stomach and their breasts are placed in two coils, which focus radio waves and allow for more complete ... > more -
Neurologists, Imaging Scientists Use Medical Physics to Spot Disease in Blood Vessels
A new brain-imaging method allows physicians to diagnose Alzheimer's before its onset. A radioactive dye is injected in the blood and travels to the brain, where it attaches to plaque deposits of ... > more -
Neurosurgeon Devises MRI-Based Technique to Diagnose Sciatica
Up to 40 million American suffer from sciatica pains, but the condition is often not diagnosed correctly. A new imaging technique uses a specially tuned MRI scan to image nerves and highlight them ... > more -

MRI Can Replace CT Scans, Reducing Cancer Risks
New studies by radiologists have shown that MRI can be just as accurate as CT scans at helping radiologists diagnose pathologies such as cancer, cysts and kidney stones -- while carrying less risk, ... > more -
Portable Machines Go Beyond Prenatal Uses
Ultrasound uses sound waves that bounce off body parts, producing echoes. A computer translates the echoes into images that rival the quality of CAT scans and MRIs, showing broken bones, muscle ... > more -
CT Scans of Legs May Help Prevent Recurring Pulmonary Embolisms
Pulmonary embolisms kill 60,000 people every year. Often, the clots form in the legs, break free and travel to the lungs, where they can cause sudden death. CAT scans can identify these clots in the ... > more
