Voluntary breath-hold reduces dose to organs at risk in radiotherapy of left-sided breast cancer.

Aim: To compare the dose to organs at risk with free breathing (FB) or voluntary breath-hold (VBH) during radiotherapy of patients with left sided breast cancer.

Background: Radiotherapy reduces the risk of breast-cancer-specific mortality but the effects on other organs increase non-cancer-specific mortality. Radiation exposure to the heart, in particular in patients with left sided breast cancer, can be reduced by breath hold methods that increase the distance between the heart and the radiation field.

Paraneoplastic Cerebellar Degeneration as Initial Presentation of Papillary Carcinoma of the Fallopian Tube: Evaluation and Usefulness of (18)F-FDG PET-CT. Case Report and Literature Review.

The acquisition of an (18)F-FDG PET-CT scan in patients with suspected paraneoplastic cerebellar syndrome can be helpful in determining the origin of a neoplasm because of its high sensitivity and also helps guide the neurological development course depending on the degree of incorporation of (18)F-FDG to the cerebellar parenchyma when compared with the rest of the brain.
