Ultrasound

Standard musculoskeletal ultrasound is better than gold standard radiography at detecting overall joint pathology in the hands and feet of patients with psoriatic arthritis. MR imaging showed marginally better sensitivity at detecting joint effusions and synovitis, while radiography detected more erosions in the joints. But the low cost and comparable performance of ultrasound make it a viable tool for assessment of the small joints of patients with psoriatic arthritis.

Unnecessary surgeries for suspected, but ultimately benign, ovarian tumors could be reduced if ultrasonography is improved, according to a recent report in The Lancet Oncology. The study showed that the number of surgeries for suspected cancers was significantly higher after routine ultrasounds compared with ultrasounds performed by sonographers who have more than 10 years of experience.

Ultrasound assessment of cervical length in first pregnancies past 41 weeks can serve as an independent predictor of the likelihood of spontaneous labor and successful vaginal delivery. Cervical length was shorter in women who experienced spontaneous onset of labor.

Three-D ultrasound designed for cardiac imaging may be just what interventionalists need to improve the administration of nerve blocks, according to researchers at the Mayo Clinic in Jacksonville, Florida.

Ultrasound is the most commonly used abdominal imaging modality. The addition of color and spectral Doppler imaging has been particularly beneficial. When ultrasound findings are nonspecific, however, patients are generally referred to CT or MRI

The American Society of Echocardiography has issued a new consensus statement for interpreting and responding to results of carotid artery ultrasound. The guidelines set carotid artery wall thickness values greater than the 75th percentile as the threshold for aggressive treatment.

Color Doppler flow and sonographic wall thickness are as good as -- and in some cases better than -- contrast MRI for showing the extent of Crohn’s disease. Both ultrasound and MRI match clinical results from barium studies, surgery, and colonoscopy.

The colossal linemen of the National Football League and large folks in general may have more in common than their size. Everyone who weighs more than 300 pounds is more than twice as likely as a lighter person to die from a heart attack or stroke, according to a study sponsored by the Living Heart Foundation.

Ablation using high-intensity focused ultrasound can effectively control some types of localized prostate cancer for five years or longer, according to a study by German researchers.

Ultrasound exams conducted by expert sonographers make a measurable difference over routine exams in the treatment of suspected ovarian cancer, decreasing the number of major staging procedures and reducing in-patient hospital stays.

Contrast-enhanced ultrasound is almost as accurate as contrast-enhanced CT for diagnosing solid organ injuries in children following blunt abdominal trauma. This less expensive option is also beneficial because it doesn't require irradiating young patients.

Ultrasound exams of patients with a history of idiopathic carpal tunnel are better diagnostic tools than the standard physical maneuvers known as Tinel’s sign and Phalen’s maneuver.

Global demand for hand-carried ultrasound units rose 42% in 2007, according to industry analyst Harvey Klein. Total medical sales were $565 million compared to $398 million the year before.

A study by University of British Columbia researchers has found that ultrasound-guided prolotherapy can alleviate the pain of patients with chronic tendinosis of the Achilles tendon.

The massive American College of Radiology Imaging Network 6666 trial shows that adding ultrasound to the initial breast screening protocol for high-risk women could help detect 30% more cancers, but at the questionable cost of many more needless biopsies of benign lesions.

New data presented at the 2007 RSNA meeting may help ease fears that use of preoperative breast MRI will hike mastectomy rates and cause delays in time to surgery.
