In patients with cancer undergoing routine ECHO, the cardiothoracic ratio at routine CT scans was highly correlated with that at CXR. Preliminary estimates in this small study indicate a low likelihood of LVH when the CTR is less than 0.49.

OBJECTIVE: To document the incidence and clinical characteristics of (tropical) pyomyositis in a predominantly First Nations population in northwestern Ontario. METHODS: The present study was a retrospective case series conducted over a 38-month period in a population of 29,105 in northwestern Ontario. RESULTS: The authors identified seven cases of pyomyositis and describe demographics, comorbidity, clinical course, and the results of imaging and microbiology investigations. The incidence of pyomyositis in northwestern Ontario is 7.6 cases per 100,000 person-years, a rate that is approximately 15 times higher than the only published incidence rate for a developed country (Australia). CONCLUSION: The rate of pyomyositis is high. It may be mediated by overcrowded housing, inadequate access to clean water, and high background rates of methicillin-resistant Staphylococcus aureus infection, injection drug use, and type 2 diabetes mellitus.

Advances made since the first application of breast magnetic resonance imaging (MRI) in the late 1980s have made it an integral complement to a comprehensive breast assessment centre. Incorporating breast MRI into an existing practice can appear daunting, but a structured and organized approach allows for a smoother transition. With a well thought out plan that engages all team members and experience in interpretation and performing of interventional procedures, breast MRI will serve to add valuable information in patient management.
