"Digistain," which uses invisible mid-infrared light to photograph tissue slices, could help eliminate the human subjectivity and variability in grading cancer tumors, according to research published in Convergent Science Physical Oncology.

T2 weighted-based radiomics proved superior in classification performance than qualitative assessment and diffusion-weighted (DW) imaging for diagnosing pathologic complete response (pCR) in patients with rectal cancer who received therapy prior to their main treatment, according to a March 8 study in Radiology.

One-time prostate-specific antigen (PSA) cancer screenings in men does not improve mortality rates for the disease, according to a study published online March 6 in JAMA.

Zika virus has had a significant impact in North and South America, most notably by causing microcephaly in babies born to infected mothers. But Brazilian researchers have found the deadly virus may be an effective treatment for glioblastoma—the most common and aggressive form of malignant brain tumor in adults.

In patients with early-stage breast cancer, neoadjuvant chemotherapy (NAC) is a common treatment to reduce tumor size before surgery. A team has found dynamic diffuse optical tomography (DDOT) can detect if a tumor has responded to chemotherapy within two weeks of initial treatment—potentially life-saving information for patients. ​​​​​​​

Nonsmoker lung cancer curiously on the rise in the UK

The annual frequency of never-smokers developing lung cancer in Britain has more than doubled over the last seven years, from 13 percent to 28 percent, according to a study set to run in the October edition of the European Journal of Cancer.

Nuke-med tracking aids management of advanced biliary tract cancer

Rare but aggressive, cancers of the bile duct can be added to the list of carcinomas for which PET scanning with the radiotracer 18F-FDG adds diagnostic and/or prognostic value, according to the authors of a study running in the August edition of the Journal of Nuclear Medicine.

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.
