Diagnostic Imaging


Recent research published in Current Problems in Diagnostic Radiology suggests new strategies in thyroid fine needle aspiration to avoid biopsies may be safer and more cost effective in older patients.

A study in the March issue of the American Journal of Roentgenology found that minority, socioeconomically disadvantaged, high-risk populations may be more prone to developing late-stage and aggressive lung cancers than more privileged communities.

New research suggests emergency patients are often given unwarranted CT scans to check for skull fractures and brain hemorrhage, resulting in wasted healthcare dollars and increasing exposure to radiation, according to an American Roentgen Ray Society (ARRS) press release.

Colorectal cancer is the second leading cause of cancer-related death in the U.S., but a lack of education and invasive procedures keep screening numbers down.

Patients with anterior cruciate ligament (ACL) mucoid degeneration at MRI who are also at-risk for osteoarthritis (OA) are associated with progression of joint space loss in the primary weight-bearing area of the knee, according to research published online Feb. 21 in Radiology.

CEUS works well for central-line check, less so for ruling out misplacement

Contrast-enhanced ultrasound (CEUS) imaging is safe, efficient and highly specific for confirming location and placement of central venous catheter tips in adult patients, according to a medical literature meta-analysis running in the December edition of the Journal of Ultrasound in Medicine.

POCUS excels in management of intra-abdominal hypertension

Point-of-care ultrasound has shown notable prowess as an adjuvant tool for aiding both diagnosis and treatment of intra-abdominal hypertension (IAH), a common complication in critically ill patients, according to a study published online Nov. 28 in Anaesthesiology Intensive Therapy.

RSNA 2017: Exercise alone won’t fend off osteoarthritis in knees

Exercise and improvement in eating habits, as two recommendations from a physician, could improve the overall health of most patients. Weight loss is associated with plenty of benefits. But MRI evidence presented at RSNA 2017 shows how an individual sheds extra pounds can impact the progression of knee osteoarthritis.

POCUS aids palliative care in poorer rural regions

In resource-strapped parts of the world, point-of-care ultrasound can help palliative care clinicians provide better care for patients with life-limiting conditions and, in turn, offer more confident guidance to these patients’ families, according to a study published online Nov. 15 in the Journal of Clinical Oncology.

MRI may be more trouble than it’s worth for diagnosing ACL tears

Athletes suffering suspected tears of the anterior cruciate ligament (ACL) are often adequately assessed with clinical diagnostic tests performed in the clinician’s office. When these are inconclusive, diagnostic arthroscopy is the gold standard—and MRI is a generally low-value option due to its time and cost burdens.

Baby MRIs show prolonged anesthesia may cause brain atrophy

Parents may start to reconsider treatment options when it comes to the effects of anesthesia on their children thanks to new findings from Boston Children's Hospital. 

Defective lead aprons give themselves up to infrared light

Radiology researchers at Children’s National Health System in Washington, D.C., have shown that infrared thermal testing is better than the human touch at finding wear spots and other defects in protective lead aprons.

Awaiting imaging results, patients remain patient for up to 3 days

After getting imaged, outpatients expect to hear back on the results within one to three days. If the wait goes longer than that, they’re likely to feel worried—or perhaps perturbed—and call in for themselves within five days, according to researchers at the University of Michigan.

Follow-up head CT in elderly trauma patients can detect new hemorrhages

Routine follow up CT imaging in elderly patients who have experienced head trauma may need to be implemented into standardized treatment plans at a more cost-effective rate, according to a recent article by JACR.  

New emergency rad-report system passes test

Radiologists and ED physicians at Brown University have developed a simple, five-category system for triaging imaged emergency patients based on their radiology reports, and the team’s test of the system has shown very good interobserver agreement.
