Peering into the body and visualizing its molecular secrets one step closer to reality

Peering into the body and visualizing its molecular secrets, once the stuff of science fiction, is one step closer to reality with a study from researchers at the Stanford University School of Medicine and the University of California, San Diego School of Medicine.

Decoding gene expression in cancer tumors using noninvasive imaging

By correlating images of cancerous liver tissue with gene expression patterns, a research team led by a radiologist at the University of California, San Diego (UCSD) School of Medicine has developed tools that may some day allow physicians to view a CT image of a cancer tumor and discern its genetic activity.

Simple clinical criteria can eliminate pulmonary embolism risk and expense

Although clots in the lung (pulmonary embolism or PE) are the second-leading cause of sudden death in the United States, blood tests and ultrafast CT scanning to detect PE are being used on so many patients that over 90% of these tests are negative.

Surgeons rebuild war veteran's nose using his own body parts

It took only seconds for the Humvee to flip over and crash on a highway near Camp Bucca in southern Iraq in August 2005.

Computer models predict mechanical stresses in any region of the skeleton

Journal of Biomechanics, the most prestigious journal in biomechanical research, published on 12 April 2007 the electronic preprint of a paper entitled: "Schileo E, Taddei F, Malandrino A, Cristofolini L, Viceconti M. Subject-specific finite element models can accurately predict strain levels in long bones. J Biomech. 2007 Apr 12'".

Distant ancestor less mentally advanced than expected

A surprisingly complete fossil skull of an ancient relative of humans, apes and monkeys bears striking evidence that our remote ancestor was less mentally advanced than expected by about 29 million years ago.

CT and MRI are highly accurate at determining which patients would be optimal candidates for liver transplantation

CT and MRI are highly accurate at determining which patients would be optimal candidates for liver transplantation, says a recent study.

FDG-PET imaging predicts lung cancer patients' response to chemotherapy

An earlier indication of whether chemotherapy benefits non-small cell lung cancer patients, provided by positron emission tomography (PET) imaging, can guide doctors in offering them better care, according to researchers in the May Journal of Nuclear Medicine.

Low-dose MDCT of the abdomen and pelvis reduces hospital stay in patients with acute nonspecific abdominal pain

Extremely low-dose MDCT of the abdomen and pelvis is useful in providing needed diagnostic information and reducing hospital stay in patients with acute nonspecific abdominal pain, according to a new study by researchers from the Emory University School of Medicine in Atlanta, GA, and Massachusetts General Hospital in Boston, MA.

CT angiography can replace digital subtraction angiography

CT angiography (CTA) alone is an effective, noninvasive means to detect peripheral vascular disease, according to a study conducted by researchers at Charite Campus Benjamin Franklin in Berlin, Germany.

PET-CT is better for early detection of muscular lymphoma than CT alone

For the study, PET-CT was used to image 305 patients with lymphoma. Twelve of these patients had muscular involvement in which 10 were biopsy proven and two were proven by imaging follow-up.

New option for soft-tissue imaging in interventional radiology procedures

Soft-tissue cross-sectional imaging acquired on a flat panel C-arm fluoroscopic unit located in the interventional radiology area is feasible and useful for interventional radiology procedures, avoiding the necessity of sending patients out to a CT scanner, according to a new study by researchers from the Baptist Cardiac & Vascular Institute in Miami, FL.

High intracoronary attenuation significantly improves diagnostic accuracy in 64-slice CT-CA of the coronary arteries

For the study, 170 patients with suspected coronary artery disease underwent CT-CA. The average vascular attenuation measured in the aortic root and in coronary arteries was used to divide the population into two groups of 85 patients each, one with low attenuations and one with high.

CT angiography has a nearly 100% detection rate in acute ruptured, cerebral aneurysms

CTA correctly detected the ruptured aneurysm in 170 cases when compared to intraoperative findings, Bijal Patel, MD, lead author of the study. Of the 22 cases where there was more than one aneurysm, CTA correctly identified the ones that were ruptured every time.

CT colonoscopy has 90 percent agreement rate with optical colonoscopy

Nearly 90% of colon polyps greater than or equal to 6 mm in size detected at CT colonoscopy were demonstrated to represent true polyps at subsequent optical colonoscopy (the traditional method of viewing the colon and removing precancerous growths), according to a new study by researchers from the University of Wisconsin Hospital and Clinics in Madison, WI.

CT imaging can play important role in car crash testing

Crash test injuries analyzed with CT imaging provide valuable data that can help engineers develop safer cars and reduce the severity of injuries during car accidents, according to a new study by researchers from The Ohio State University in Columbus.

CT better than plain radiographs in diagnosing lumbar spine fractures

Lumbar spine fractures in a majority of patients with trauma can be detected by routine trauma abdomen and pelvis CT compared to plain radiographs, according to a recent study conducted by radiologists at the University of Cincinnati in Cincinnati, OH.

Vigorous active lifestyle keeps people thin with age

The old adage "use it or lose it" is truer than ever. People who maintain a vigorously active lifestyle as they age gain less weight than people who exercise at more moderate levels, according to a first-of-its-kind study that tracked a large group of runners who kept the same exercise regimen as they grew older.

New treatments for brain hemorrhage

The first scientifically proven treatments for intracerebral hemorrhage, or "bleeding," strokes, are on the horizon, including a new drug that holds promise for slowing bleeding and limiting brain damage resulting from such a stroke, according to updated American Heart Association/American Stroke Association guidelines.
