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.

Sonography Current Events and Sonography News RSSFirst acoustic metamaterial 'superlens' created by U. of I. researchers
A team of researchers at the University of Illinois has created the world's first acoustic "superlens," an innovation that could have practical implications for high-resolution ultrasound imaging, non-destructive structural testing of buildings and bridges, and novel underwater stealth technology.
Ultrasound more cost efficient than other medical imaging choices
In comparing ultrasound with other medical imaging methods such as MRI and CT scans, a literature review of published studies in the May/June issue of Journal of Diagnostic Medical Sonography (JDMS) describes the use of ultrasound to provide an accurate diagnosis more cost effectively than the alternatives.
3T MRI Detects "Early" Breast Cancer Not Seen on Mammography and Sonography
3T MRI, a powerful tool for evaluating patients with a high risk of having breast cancer, can detect a significant number of lesions not found on mammography and sonography.
Ultrasound Changes Care of Some Patients with Rheumatic Conditions
Ultrasound can be used to make an appropriate decision regarding care for patients with rheumatic conditions involving the hands and feet, according to a study performed at St. Joseph's Healthcare/McMaster University in Hamilton, Canada.
New ultrasound-guided biopsy method allows improved diagnosis of endometrial disease

What is the clinical character of Fitz-Hugh-Curtis syndrome?
Fitz-Hugh-Curtis syndrome is characterized by inflammation in perihepatic capsules with concomitant pelvic inflammation. The pain in the right upper abdomen appeared as the main symptom.
Computer model improves ultrasound image
Doctors use diagnostic sonography or ultrasound to visualise organs and other internal structures of the human body.
Ultrasound first, not CT, for diagnosing suspected acute appendicitis
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.
