Ultrasound leads conservative treatment of calvarial dermoids

July 09, 2008

Calvarial dermoids and epidermoids in young pediatric patients can be monitored using ultrasound alone instead of x-ray based imaging, according to German researchers. Besides being safer and cheaper, sonography could rule out unnecessary surgeries.

Bedside ultrasound provides easy way to monitor lungs of heart failure patients

June 24, 2008

Bedside ultrasound can be a valuable diagnostic tool for monitoring pulmonary congestion in patients with acute decompensated heart failure. As the heart weakens, fluid backs up into the lungs, and critical patients could benefit greatly by being monitored for their condition without having to be moved for radiographs or other diagnostic tests.

Contrast-enhanced ultrasound shows vascular details of liver nodules

June 16, 2008

Contrast-enhanced ultrasound with microflow imaging provides noninvasive analysis of the vascular structure and hemodynamics of liver nodules. This analysis, in turn, provides information about how advanced hepatocellular carcinoma is.

Endoscopic ultrasound proves to be safe and effective in children

June 09, 2008

Endoscopic ultrasound, a common test for adults, is rarely used on children. Researchers in Israel who studied the efficacy of the test on these smaller patients have found it to be a safe and effective tool for diagnosing pediatric gastroenterology patients.

Contrast-enhanced ultrasound diagnoses small renal lesions

June 03, 2008

Solid renal parenchymal lesions with a diameter of 5 cm or less can be difficult to diagnose, requiring irradiation and biopsy. Catching renal cell carcinoma in early stages before tumors grow larger than 7 cm, however, increases a patient’s chances of survival over five years. Researchers in China have found that contrast-enhanced ultrasound can accurately diagnose these small lesions.

Optic nerve sonography reliably indicates intracranial pressure

May 26, 2008

Ultrasound measurement of optic nerve sheath diameter can gauge intracranial pressure in patients who cannot tolerate invasive assessments. Sonography has proved useful in brain-injured pediatric patients, and a recent study confirmed that optic nerve sheath diameter correlates with intracranial pressure in adults with brain injuries.

Ultrasound elastography quickly identifies malignant thyroid nodules

May 19, 2008

Ultrasound elastography provides an accurate diagnosis for malignant thyroid nodules about eight out of 10 times, according to Italian researchers. Elastography has previously shown promise in the diagnosis of breast and prostate cancers.

Emergency triage uses portable ultrasound to spot pulmonary embolism

May 12, 2008

Portable ultrasound in the emergency room can identify pulmonary embolism in patients having difficulty breathing, allowing for prompt treatment.

Ultrasound proves as good as MRI for presurgical staging of endometrial cancer

May 05, 2008

Transvaginal ultrasound exams conducted by expert practitioners can replace MR imaging for preoperative staging of endometrial cancer. Researchers conclude that expensive MRIs should be reserved for patients whose ultrasound exams are unclear.

Lung ultrasound quickly spots acute respiratory failure

April 28, 2008

Specific lung ultrasound signs reliably indicate common causes of acute respiratory failure and rapidly differentiate it from similar diseases. More than 90% of patients admitted to university teaching hospital intensive care units with trouble breathing could have been easily diagnosed with lung ultrasound.
