Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT.

High-dose radiation therapy improves survival in formerly incurable cancer patients

Results of a new randomized, phase II clinical trial have demonstrated an aggressive form of precision radiation therapy can increase the lifespan of oligometastatic cancer patients and doubles how long they can live without cancer, according to the American Society for Radiation Oncology (ASTRO).

X-ray utilization for infants with bronchitis still high

In spite of guidelines recommending against routine x-rays for infants diagnosed with bronchitis, new analysis of emergency department visits in the United States suggests there has been no decrease in x-ray utilization.

Unenhanced CT should be first test for adults with new-onset seizure

For adults with a new-onset seizure, what neuroimaging test, if any, should initially be performed to prevent serious complications or emergency intervention? A new analysis published in the American Journal of Roentgenology recommends unenhanced CT with MRI as a supplementary technique for patients whose CT is negative and those in the non-acute setting.

Study: Frequent lung cancer CT screening doesn't improve survival rate

More frequent surveillance imaging does not improve overall survival or post-recurrence survival for patients with non-small cell lung cancer (NSCLC), according to research published in the October issue of Annals of Surgery.

Is breast US, mammography or both ideal for women under 40 with focal breast symptoms?

Breast ultrasound should be used as the primary initial imaging modality when evaluating focal breast symptoms in women 30 to 39 years old, according to research published Oct. 9 in the American Journal of Roentgenology. Although mammography can detect symptomatic breast cancer, the researchers found its cancer detection rate (CDR) to be lower than that of ultrasound.
