Using contrast enhanced sonography improves diagnosis of liver and spleen injuries
October 02, 2006Contrast-enhanced sonography shows liver and spleen injuries better than non-contrast enhanced sonography, according to a study conducted at the University of California, Davis School of Medicine department of radiology in Sacramento, CA.
This study included 22 liver, spleen or renal injuries. Contrast-enhanced sonography depicted 20 (91%) of the 22 injuries while non-contrast-enhanced sonography revealed 11 (50%).
"The main focus of sonography for patients with blunt abdominal trauma is to detect free fluid," said John McGahan, MD, lead author of the study. Free fluid is non-clotted blood within the peritoneal cavity. "However, there could be an organ injury without free fluid and the injury could be missed," he said. "Contrast-enhanced sonography allows the radiologist to see free fluid as well as the injury itself," he said.
On a scale ranging from 0, being non-visualization, to 3, being high visualization, the average grade went from 0.67 to 2.33 for spleen injuries and from 1.0 to 2.2 for liver injuries when comparing contrast-enhanced sonography to non-contrast-enhance sonography, said Dr. McGahan.
"We are very happy with the results and can say that the use of contrast-enhanced sonography is accurate for depicting solid organ injuries," said Dr. McGahan.

Color Doppler ultrasound, not CT, should be the first imaging examination for adult patients with suspected acute appendicitis, a new study emphasizes.
Cancer could return unless stored ovarian tissue undergoes adequate testing before re-implantation
Cancer patients who have been successfully treated for their disease face the prospect of its return if stored ovarian (or testicular) tissue is transplanted back into their bodies without adequate checks, according to researchers at two university hospitals in Israel.
Mammography plus sonography can help rule out breast cancer in patients with palpable lesions
When mammography and sonography are used together to evaluate palpable breast lesions, they can rule out cancers in most patients, according to a recent study conducted by researchers at Baystate Health in Springfield, MA. However, uncommonly, malignancies cannot be diagnosed using this imaging protocol.
In-vitro fertilization improved with 3-D/4-D-guided embryo transfer and new placement target
Beverly Hills, Calif. and Washington DC (ASRM Annual Meeting) - October 15, 2007 - The pregnancy rate for patients undergoing in-vitro fertilization (IVF) is improved when doctors use advanced 3D/4D imaging to guide the placement of embryos to the point where the endometrium is most receptive to implantation.
Different method of evaluating the urinary tract system reduces radiation dose
The split-bolus (cross sectional imaging) MDCT urography technique reduces both radiation dose and number of images produced, according to a recent study conducted by radiologists from Stanford University School of Medicine in Stanford, CA and VA Palo Alto Health Care System in Palo Alto, CA.
Study proves alcohol injections for common cause of foot pain highly successful
Sonographically-guided alcohol injections has a high success rate and is well tolerated by patients with Morton's neuroma, a common cause of foot pain.
Dynamic sonography accurate in diagnosing muscle tears
Dynamic sonography is useful in the diagnosis, management and follow-up of muscle tears and hematomas, according to a recent study conducted by researchers from Khoula Hospital in Muscat, Oman.
Ultrasound could help couples undergoing IVF
Ultrasound-based tests allowing women undergoing in-vitro fertilization (IVF) to count their chickens before they've hatched may provide alternatives to the hormone-based tests used today. Less costly and invasive than the current ovarian reserve tests, clinicians may in future consider using ultrasound scans of a woman's ovaries to predict her ovaries' response to IVF.
Study recommends new tool to assess blunt abdominal trauma
Contrast-enhanced sonography compared with sonography and CT proves to be a useful tool in the assessment of blunt abdominal trauma, concludes a study conducted by the departments of emergency, internal medicine, and radiology at the University of Bologna in Bologna, Italy.
Prenatal sonography has no effect on the intellectual capacity of the developing child
Scientists carrying out a major epidemiological study at Karolinska Institutet and Uppsala University have discovered that there is no clear correlation between routine ultrasonic scans and intellectual impairment. "Fears have been expressed that sonography can lead to diminished intellectual capacity," explains Helle Kieler, research scientist at Karolinska Institutet.
