Oncology Imaging

 

Five years ago the American Society of Clinical Oncology (ASCO) advised clinicians not to order advanced imaging or tumor marker tests for survivors of early-stage breast cancer. Yet the exam orders keep coming.

Reviewing brain MRI of close to 4,000 children as part of an ongoing population-based study, European neuroradiologists and neuroscientists discovered at least one incidental finding in more than one-quarter of the cohort.

The National Academy of Medicine announced Monday, Oct. 17, that it elected 80 new members, including Deborah Watkins Bruner, RN, PhD, a professor of radiation oncology at Emory University in Atlanta. 

A single 90-minute examination designed to assess chemotherapy-induced injuries of the brain, heart and joints among childhood cancer survivors has been proven feasible by a new study.

Starting annual screening mammography for breast cancer at age 40 helps detect a significant number of cancers, according to a recent study published in the American Journal of Roentgenology.

Prostate cancer may face new foe in photoacoustic/ultrasound imaging

Researchers at Japan’s National Defense Medical College have developed an ultrasound-equipped photoacoustic imaging (PAI) system that shows potential for imaging the angiogenesis, or formation of troublesome new blood vessels, in prostate cancer.

CT colonography coverage hoists screening rates

Individuals who have insurance covering CT colonography are almost 50 percent more likely to get screened for colon cancer by either that option or colonoscopy—both of which can help prevent as well as detect cancer—than those who lack such coverage, according to a study published online July 11 in Radiology.

Brain ultrasound during tumor surgery matches pre-op MRI guidance and then some

Italian researchers have shown how surgeons resecting glioblastomas, the most common and aggressive brain tumors, can use contrast-enhanced ultrasound to guide their view of tumor location, morphologic features, margins and dimensions in real time and for the duration of the entire surgery.

MRI adds real value to prostate cancer diagnostics

Diagnostic prostate MRI can be a good tool for triaging biopsy candidates, as the one-two punch of that exam followed by MRI-guided biopsy of suspicious lesions has again proven not only clinically efficacious but also cost-effective when compared with transrectal ultrasound-guided biopsy. 

MRI guidance enables more comfortable prostate biopsy

Prostate biopsy via the perineum with local anesthetic and MRI targeting is feasible, tolerable and can be performed in ambulatory settings, according to a British study published online May 9 in Prostate Cancer and Prostatic Diseases.

Long look at lots of rad techs: No link between work-related radiation exposure and fatal brain tumors

After assessing several decades’ worth of survey data on more than 110,000 radiologic technologists, researchers have all but ruled out a dose-response association between cumulative protracted occupational radiation and death by brain tumor.  

Mobile lung screening unit eliminates barriers to access in Carolinas

Levine Cancer Institute launched the first mobile lung CT unit to provide cancer screening to rural communities in North and South Carolina, two states with above-average rates of lung cancer diagnosis.

Gadolinium MRI superior to contrast CT for evaluating some here-and-gone metastases

MRI enhanced with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid—the scan referred to as “EOB MRI”—is significantly better than contrast-enhanced CT for assessing colorectal liver metastases that disappear after chemotherapy, according to a study published online March 22 in Radiology.

Geography, not patient need, driving endoscopic ultrasound utilization

A group of researchers from the University of Wisconsin found patients who underwent endoscopic ultrasound (EUS) had longer times-to-surgery than those who didn’t. Led by resident Ryan Schmocker, MD, the team linked certain geographical areas and institutional factors to a higher likelihood of undergoing EUS, in addition to a baseline increase in utilization nationwide.

Recurrent skin cancers more likely to be found by patient self-checks than by imaging

Patients and their physicians detect more recurrences of melanoma than routine surveillance imaging does, according to a study published online Feb. 8 in the Journal of the American College of Surgeons.
