By

Researchers identified a potential new way to predict which patients with head and neck cancer will benefit most from chemotherapy.

Increased detection of low-risk tumors driving up thyroid cancer rates

By

Low-risk cancers that are asymptomatic and presumably will not cause problems in the future are responsible for the rapid increase in the number of new thyroid cancer diagnoses over the past decade, according to a study.

Imaging technique allows pediatric brain tumors to be classified noninvasively at diagnosis

By

Researchers have discovered that determining a tumor's medulloblastoma subgroup can be achieved noninvasively, using magnetic resonance spectroscopy (MRS).

By

A new procedure for analyzing radiologic imaging scans increases the chance to accurately predict the course of malignant gliomas.

Appropriate use of tomosynthesis mammography

Appropriate use of tomosynthesis mammography

By

With the availability of tomosynthesis mammography, should women at high risk for developing breast cancer still undergo annual MRI?

Follow-up PET/CT more than 95% sensitive for non-Hodgkin lymphoma

By

BALTIMORE, MD—For more aggressive cases of non-Hodgkin lymphoma (NHL), posttreatment surveillance with molecular imaging could mean the early start of a new, life-saving treatment. This was presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2015 Annual Meeting.

Imaging technique identifies early metastasis in lymph nodes

By

A new, accurate imaging technique, combining photoacoustics with nanosensors, has been developed for the noninvasive screening of lymph nodes for metastatic cancer.
