PET hybrid technologies are already hot, and two innovations discussed during the final session of ECR 2011 are aimed at making them more even powerful and efficient.

A molecular imaging technique may prove useful in early assessment of treatment response for cisplatin-resistant ovarian cancer, according to a study published in the Journal of Nuclear Medicine.

PET with CT colonography provides an alternative for detecting polyps and cancer in the colon, according to a study published in the Journal of Nuclear Medicine.

Researchers in the radiation oncology department at UCLA’s Jonsson Comprehensive Cancer Center have received a $14 million grant to develop countermeasures that will help treat damage caused by radiological or nuclear threats such as a dirty bomb attack.

Radiation in any form brings risk. Medical radiation as a screening, diagnostic or treatment tool is designed with safeguards in mind to minimize the risk and maximize the benefit of the test or treatment. For instance, if a patient presents with a breast lump that can be felt but not viewed with mammography or ultrasound, medical professionals must employ the most appropriate diagnostic tools that identify potential cancer.

Some nuclear-based breast imaging exams may increase a woman’s risk of developing radiation-induced cancer, according to a special report appearing online and in the October issue of Radiology. However, the radiation dose and risk from mammography are very low.

A commonly used probe for PET scanning and a new probe developed by researchers at UCLA reveal different functions in diverse cells of the immune system, providing a much clearer picture of an immune response in action.
