Radiotherapy is a major tool in the clinician's arsenal against cancer, and new techniques are being developed that minimize damage to healthy tissue next to the targeted cancerous tumors, as well as improve the treatment effect by concentrating the radiation dose where it is most needed.

An off-label use of MRI is showing significant promise in the treatment of patients with thalassemia, a condition that often requires frequent blood transfusions which leave patients at risk for complications from a dangerous build-up of iron in the heart.

While the next generation of technology for breast cancer screening may well be based on digital breast tomosynthesis (DBT), there is another promising approach under development that also can produce three-dimensional images of the breast. Investigators in Texas and New York are reporting positive developments with respect to cone-beam breast CT (CBBCT), an approach that may be able to deliver certain advantages in terms of exam time, comfort, and diagnostic accuracy.

A newly released guideline on colorectal cancer screening offers recommendations for various alternatives for colorectal cancer detection, including — for the first time — radiological examination by CT colonography (CTC), also known as virtual colonoscopy.
