An emerging deep learning radiomics model, based on B-mode ultrasound and color Doppler flow imaging, demonstrated a 91 percent AUC for predicting lymphovascular invasion in a multicenter study of women with invasive breast cancer.
Ultrasound can detect aneuploidy, structural fetal anomalies in first trimester
November 1st 2010Not only is it possible to detect aneuploidy and structural fetal anomalies with sonography during the first trimester, but doing so allows for better treatment options, according to a study published in the Journal of Ultrasound in Medicine.
Indian radiology association secretary suspended for fetal sex determination test
March 29th 2010A regional secretary of the Indian Radiology and Imaging Association and two other doctors were accused of conducting sex determination tests on decoy patients, according to an article in the Times of India.
Fetal MRI bests traditional-controversial-autopsies
August 18th 2009When it comes to determining the cause of death for fetuses, parents may have another option besides conventional autopsy. Whole-body high-field MRI offers a reliable option for postmortem exams in a less invasive way, according to British researchers.
Findings blow whistle on suspected gender selection
July 1st 2009An abnormally low female birth rate among the Asian population in California's Santa Clara County may be closely related to the fetal keepsake ultrasound industry's growth in a region covering San Jose and the homes of nearly two million residents.
Thermal effects of fetal US remain uncertain
September 8th 2008A study on thermal effects of diagnostic fetal ultrasound could not confirm a causal relationship between exposure and obvious adverse effects. Study authors cautioned, however, that subtle effects cannot be ruled out and called for more research.
Brain anomalies on fetal MRI call for postnatal imaging backup
June 3rd 2008Posterior fossa anomalies detected on fetal MR imaging should be confirmed with postnatal imaging, according to a study in the June American Journal of Roentgenology. Investigators from the U.S. and Canada found significant discrepancies between fetal and postnatal posterior fossa findings on MRI.
Obesity in pregnant women impairs obstetric sonography
June 1st 2008Canadian researchers have found that pregnant women who are overweight or obese are more than 10 times more likely than women of normal weight to have their second trimester fetal ultrasound screening recalled due to poor results. Worse yet, a second exam may not improve visualization but instead add only to cost and patient distress.
Report from ARRS: Obesity impairs obstetric sonography
April 18th 2008Canadian researchers have found that pregnant women who are overweight or obese are more than 10 times more likely than women of normal weight to have their second trimester fetal ultrasound screening recalled due to poor results. Worse yet, a second exam may not improve visualization but instead add only to cost and patient distress.
Radiation spotlight shows jump in pregnancy imaging
January 10th 2008One of the first studies to evaluate rates of radiological exams that expose pregnant women to ionizing radiation found a dramatic increase in the utilization of diagnostic imaging. The increase is driven largely by CT studies of the head and CT pulmonary angiography.
Three-D sonography measures fetal bladder volume with ease
July 23rd 2007Traditional ultrasound has long been used to take bladder measurements of fetuses as early as 11 to 14 weeks gestation, including length and echogenicity. But measurement of bladder volume has tended to be inaccurate because of the limited algorithms for estimating volume using a 2D image. Fetal urine production rate can also be tricky to evaluate with 2D ultrasound.
Keepsake ultrasound videos make the rounds on YouTube
May 30th 2007Expectant parents no longer seem satisfied with keeping 3D fetal videos in their DVD collection armoire. Now they are posting them on the web. This practice could undermine organized radiology efforts to rein in unwarranted fetal sonography scans.
Duke 3D software opens door to medical and consumer applications
April 30th 2007Engineers at Duke University’s Pratt School of Engineering have come up with software that twists the data composing volumetric ultrasound images into stereoscopic views, creating images that appear to float off display monitors into 3D space. The software splits the single ultrasound image into two separate images 7° from each other -- one seen by the right eye and the other by the left.
Imaging center offers tribute to romance
February 14th 2007Pacific Coast Ultrasound of Los Alamitos, CA, operates at the nexus between medical need and self-indulgence, specializing in prenatal diagnostics and medically supervised 3D/4D prenatal elective ultrasounds. Throughout February, the center, which positions itself as a certified independent diagnostic facility, promotes a month-long tribute to Valentine’s Day.
Getting into the fetal position
August 18th 2006One of the first stories I wrote for Diagnostic Imaging magazine made a lot of radiologists unhappy. It was about sonographers who were not only performing echocardiograms in private offices but also providing interpretations. One of these techs told me she had to because she knew more about it than the cardiologist. That was 24 years ago.

Radiologists can play central role in fetal MRI's bright future
May 15th 2006This month sees a clutch of national radiological congresses taking place. The annual U.K., German, and Spanish meetings are held during May, but a more specialized event looks set to attract considerable attention: the first International Congress on Fetal MRI, to be staged in Vienna from 12 to 13 May.
