Diagnostic Imaging

 

Researchers have developed a new method for segmenting kidney ultrasound (US) images that demonstrated an increased efficiency and accuracy compared to traditional methods.

In babies born with fetal ventriculomegaly, an enlargement of the cerebral ventricles in utero, determining when cerebrospinal fluid (CSF) diversion is required after birth can be difficult.

Studies suggest on-call residents perform well in limiting errors between preliminary and final reports, but mistakes happen. Researchers examined the most common errors radiology residents make when interpreting abdominopelvic (AP) CT while on call in a study published in Current Problems in Diagnostic Radiology.

Disruption of the internal body clock is commonly associated in people with Alzheimer’s Disease (AD) and may lead to further development of the disorder. New research suggests circadian rhythm abnormalities occur earlier in people who don’t have AD, but whose brain scans may show early risk of developing the disease.

Brain imaging advances can determine a greater number of stroke victims who can receive therapy later than previously thought, according to a new study published in The New England Journal of Medicine.

Emergency residency program learns from its alumni: Ultrasound among areas needing more emphasis

Getting alums of emergency-medicine training programs to evaluate their own practice skills can help directors of said programs strengthen their curriculum where it’s weak, according to a study published online Oct. 21 in Emergency Medicine Journal. Of interest to imaging observers, the researchers found that diagnostic ultrasound was one of several ER subcompetencies in need of attention at their institution.

POCUS up to the task of finding, ruling out pediatric forearm fractures

Emergency physicians armed with point-of-care ultrasound (POCUS) may have all they need to diagnose children with suspected fractures of the distal forearm.

NYU study involves CT findings in diagnosing cecal volvulus

A recent study conducted by four radiologists at New York University assessed the utility of CT features in the detection and official diagnosis of cecal volvulus.

Ultrasound helps find seizure sites in neonatal brains

Researchers in Europe have combined ultrafast ultrasound with electroencephalography (EEG) to localize seizure sites in the brain microvasculature of newborn babies whose cortexes had developed abnormally.

Pediatric IBD patients imaged gently, accurately with MR enterography

MR enterography is an excellent performer when it comes to diagnosing active inflammation in children and adolescents with inflammatory bowel disease (IBD), especially at the per-patient (vs. per-lesion) level, according to a literature review conducted in South Korea and published online Oct. 9 in JAMA Pediatrics.

MRI outperforms ultrasound in Zika-affected fetuses

The effects of Zika virus on fetuses can be better analyzed using MRI over ultrasound as the imaging modality. According to ongoing research by the Children’s National Health System in Washington, D.C., MRI provides more detailed images that reveal more extensive areas of damage to the developing fetal brain.

MRI important in reducing re-excision rates in surgical management of HG DCIS

A study in the European Journal of Radiology suggests MRI could be an important tool in reducing the re-excision rates in the management of high grade (HG) ductal carcinoma in situ (DCIS), when used in preoperative diagnosis and evaluation.

Lumbar MRI recommended over CT for diagnosing pediatric spondylolysis

Lumbar MRI is a high performer when it comes to presenting pediatric radiologists with images aimed at confirming or ruling out spondylolysis, a common cause of low back pain among young athletes.

Technologist educators could do more to get students active in professional orgs

Students training to become radiologic technologists in the U.S. could and probably should join at least one professional society, organization or association at the state or national level in order to optimize their access to up-to-date learning resources and opportunities. However, many accredited rad-tech education programs either don’t mandate such participation or give it sufficient financial support.

Children’s ERs choosing ultrasound over CT for tummy pain; general ERs encouraged to follow suit

Pediatric patients with nontraumatic abdominal pain are less likely to receive CT scans—and more likely to be imaged with ultrasound instead—in pediatric emergency departments than their peers taken to general emergency departments (EDs).
