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. 

Obesity can improve lung cancer outcomes, but only if skeletal muscle quality is maintained

Does obesity improve lung cancer outcomes? Yes, to some extent

New research findings could help explain the “obesity paradox,” wherein being overweight is linked to both improved outcomes in certain diseases and increased mortality rates in others.
