Occult cardiotoxicity in childhood cancer survivors exposed to anthracycline therapy.

Background: More than 50% of >270 000 childhood cancer survivors in the United States have been treated with anthracyclines and are therefore at risk of developing cardiotoxicity. Cardiac magnetic resonance (CMR) has demonstrated utility to detect diffuse interstitial fibrosis and changes in regional myocardial function. We hypothesized that CMR would identify occult cardiotoxicity characterized by structural and functional myocardial abnormalities in a cohort of asymptomatic pediatric cancer survivors with normal global systolic function.

Reduced Z-axis coverage multidetector CT angiography for suspected acute pulmonary embolism could decrease dose and maintain diagnostic accuracy.

Multidetector computed tomographic angiography (MDCTA) is the method of choice for evaluation of suspected acute pulmonary embolism (PE) in most patients because it is accurate and widely available. The use of computed tomography, including MDCTA for PE, has risen dramatically over the last several years with an attendant rise in radiation exposure. Many methods currently employed to reduce radiation dose may affect image quality and potentially affect diagnostic accuracy.

Sonographically guided percutaneous radio frequency ablation of a renal cell carcinoma in a transplanted kidney.

Radio frequency ablation is an effective treatment for focal renal cell carcinoma (RCC). We report a patient with RCC in a transplanted kidney that was successfully treated with percutaneous sonographically guided radio frequency ablation.
