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. ​​​​​​​

Pairing ultrasound with a blood test to detect high alpha fetoprotein (AFP) levels demonstrated up to a 40 percent improvement in detecting early-stage liver cancer, according to new research published in the journal Gastroenterology.

Pennsylvania researchers discovered opposed-phase MRI imaging is less accurate in detecting treated spinal metastases compared to those lesions that are untreated.

Nuclear imaging may better locate recurrent prostate cancer after prostatectomy and aid in earlier detection after recurrence all while simultaneously providing the sensitive imaging needed to guide salvage radiotherapy in patients, according to a study in the February issue of The Journal of Nuclear Medicine.

MRI potentially more cost-effective than CT for imaging liver metastases

Contrast-enhanced MRI is more sensitive than contrast-enhanced CT for diagnosing liver metastases in patients with known colorectal cancer. What’s more, while it’s pricier, the MRI option can also be cost-effective, delivering returns on investment in the form of greater quality-adjusted life years for the patient.
