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.

Ultrasound shows efficacy of carpal tunnel treatments

Patients injected with a steroidal anti-inflammatory for symptom relief of carpal tunnel syndrome are well-served by follow-up imaging with ultrasound to show whether or not the treatment is working, according to a small study published online in Skeletal Radiology.

Human + computer combination improves follow-through on radiology recommendations

Following a review of radiology reports and patient records that turned up glaring communications gaps over noncritical yet potentially serious findings, an urban academic medical center has invested in software and dedicated staff to close the gaps and cut the associated risks for harm.

Neuro MRI shows cost-effective cognitive tests best for monitoring Alzheimer’s

Older patients with mild cognitive impairment (MCI) marked mainly by memory loss are most accurately evaluated with intensive neuropsychological test batteries. However, if such mental decline progresses to full-on Alzheimer’s disease, the patients are better monitored with the quicker, less costly Mini-Mental State Examination (MMSE).

Ultrasound excels at surveilling larger pancreatic cysts

Transabdominal ultrasound is an excellent tool for follow-up imaging of larger cysts on or in the pancreas, although its performance falls off as surveilled known lesions decline in size, according to a study published online Aug. 1 in Abdominal Radiology.

Most incidental findings on trauma CT go uncaptured

As emergency CT has grown in use, incidental findings in trauma patients have multiplied. No surprise there, but a study conducted at a level-1 trauma center in New York City suggests that documentation of incidental findings may be seriously lacking, with obvious potential implications for follow-up care.

Ultrasound nets a qualified win in tennis-elbow contest

Pitting ultrasound against MRI at detecting and grading tears of the common extensor tendon in patients with chronic lateral epicondylitis—aka “tennis elbow”—researchers in Poland have found the former is fine at screening for high-grade tears. However, when any tear is clear on ultrasound, MRI should be considered to precisely assess the extent of the injury, they conclude.

Gastro bleeds give it up to multiphasic, multidetector CT

The source and cause of gastrointestinal bleeding can be notoriously difficult to pinpoint, but French researchers have found 64-slice multiphasic, multidetector CT up to the job. Diagnostic and Interventional Imaging published the team’s findings online June 25.

FDA clears first NICU-friendly neonatal MRI system

The FDA has cleared an MRI system for head and brain imaging in neonatal intensive care units (NICUs).

Guided by ultrasound, ROSE thyroid biopsies obviate do-overs

South American radiology and pathology researchers have reduced unsatisfactory biopsy samples of thyroid nodules by almost a third using the rapid on-site evaluation (ROSE) technique guided by ultrasound, according to a study published online July 19 in Current Problems in Diagnostic Radiology.

Infant MRI strongly recommended for suspected cerebral palsy

Thanks largely to advances in neuro MRI, cerebral palsy—the most common motor disability in children—can now be diagnosed before babies are even 6 months old (in adjusted age, meaning going by due date rather than delivery date). The stepped-up diagnostic capabilities are key, as early detection is critical to optimizing effective intervention, the authors of a new review of the literature emphasize.
